Steak dinners, sales reps, and risky procedures: Inside the big business of clogged arteries
On June 14, 2017, just before noon, a doctor made an incision near a patient’s groin. Kari Kirk, a representative for the world’s largest medical device company, Medtronic, looked on and began texting her colleague a play-by-play.
“Fixing both legs from the ankles,” she wrote.
It was a fairly common procedure at the Robert J. Dole Veterans Affairs Medical Center in Wichita, Kansas, performed to treat blockages in the leg vessels.
Within reach were an array of Medtronic products: tubes with blades attached to shave hardened deposits off of artery walls; stents to widen blood vessels; balloons coated with therapeutic drugs.
Each time a doctor puts a foreign device in someone’s body, it carries a risk of complication, which can include clots or even require amputation. So medical experts, research and even Medtronic’s own device instructions urge doctors to use as few as are necessary.
“Just used 12 [drug-coated balloons]!!” Kirk texted her colleague.
“Does that mean I owe u $$,” he responded.
“Thats what I’m thinking!!!” she said. “And now 14 balloons?!”
“but only one stent so far??”
“So far!”
As the texting continued, her colleague replied, “U are going to want to start going to the VA all the time.”
The messages, recently unsealed in an ongoing whistleblower lawsuit, give a window into the way money and medicine mingle in the booming business of peripheral artery disease, a condition that afflicts 6.5 million Americans over age 40 and is caused when fatty plaque builds up in arteries, blocking blood flow to the legs.
Representatives from companies are often present during vascular procedures to guide doctors on how to use their complex devices. This kind of access has the potential to influence treatment plans, as companies and their representatives profit when more of their product is used.
The suit, filed in 2017 by a sales representative for a competing medical device firm, alleges an illegal kickback scheme between Medtronic and hospital employees. According to the complaint and documents released in the suit, between 2011 and 2018, VA health care workers received steakhouse dinners, Apple electronics, and NASCAR tickets, and in turn, Medtronic secured a lucrative contract with the hospital. Meanwhile, the company’s representatives allegedly “groomed and trained” physicians at the facility, who then deployed the company’s devices even when it was not medically indicated.
Independently from the whistleblower suit, internal investigators at the Wichita facility have also examined the treatment patterns of its vascular patients in recent years and found numerous cases where medical devices were used excessively. While it’s not uncommon to deploy several devices, a medical expert on the investigation team found that the VA doctors sometimes used more than 15 at a time – one used 33 – deviating from the standard of care.
“It is unconscionable – there can be no valid medically acceptable basis to cram so many devices into a human being,” wrote attorneys representing the whistleblower in legal filings from January 2023. “This is not medical treatment. This is abuse.”
Dr. Kim Hodgson, former president of the Society for Vascular Surgery and an expert retained by the plaintiff, said the findings of the internal review of patient data raise “a high level of concern regarding necessity of treatment provided,” according to case documents.
Medtronic declined to respond to ProPublica’s questions, citing the ongoing litigation. “These allegations are false and Medtronic is defending against these claims in court,” said Boua Xiong, a spokesperson for the company. Medtronic representative Kirk declined to respond to ProPublica’s request for comment.
The hospital investigation found that amputations increased sixfold in the same time frame as the procedures in question, according to internal emails, but made no conclusion about whether those two things were connected. ProPublica reached out to the VA to ask whether any patients had been harmed.
The VA is “conducting an extensive review of patient care” at the Kansas hospital, “including the number of devices used on patients – to make sure that Veterans were not harmed by any procedures,” press secretary Terrence Hayes said in a statement. So far, the VA’s investigation has found no “quality of care issues,” he said, and the investigation will continue “until every Veteran’s case has been reviewed.” (Read the full statement here.) Neither the department nor the hospital has taken formal action against the medical providers, Hayes said.
The medical group that had a contract with the VA for vascular interventions, Wichita Radiological Group, did not respond to ProPublica’s requests for comment, nor did the doctors named in the suit: Dr. Shaun Gonda, Dr. Bret Winblad, and Dr. Kermit Rust. It is unclear from the case documents which doctors conducted which procedures. Eric Barth, an attorney for the medical group, denied the allegations in recent legal filings, calling the claims “baseless” and the lawsuit a “witch hunt.”
The lawsuit comes amid growing concern about one of these procedures – atherectomies – after researchers and doctors have uncovered patterns of excessive and inappropriate use. Recent research has found that this procedure, a common but costly treatment to shave or laser plaque from blood vessels, is not more effective than cheaper alternatives and may even be associated with a higher risk of complications including amputation. In recent years, several doctors and clinics have been investigated for allegedly taking advantage of Medicare’s reimbursement rates, and one study found that many doctors are resorting to atherectomies in the earliest stages of peripheral artery disease, against best practices that urge noninvasive treatment.
“Atherectomy is important in certain settings. But it’s being used in a way that is entirely inappropriate and it’s largely driven by the incentive structure,” said Dr. Caitlin Hicks, the lead author of the study and an associate professor of surgery at Johns Hopkins University School of Medicine.
Although different payment structures govern the care of veterans, the whistleblower lawsuit alleges that outside physicians, paid hourly by the Dole VA, were motivated to conduct longer and more complex procedures that would earn them higher payment.
Under different circumstances, the patient in the procedure room on that summer day could have been done after 2 hours.
But, 150 minutes in, those Medtronic representatives were still texting. At that point, more than 15 of their vascular devices had been used, including stents, balloons, and those for atherectomy.
“Long case!” Kirk’s colleague texted. “Is it looking ok??”
“It is,” she said. “Thought we were done a few times! Now he’s going back in to cut again!”
A little while later, she texted: “....17!”
He texted back [with laughing emoticons].
Hospital leaders had been scrutinizing the use of these procedures at the Dole VA for years.
In 2017, shortly after Rick Ament was hired to lead the facility, he noticed something was amiss. While the longtime hospital administrator was poring over the finances, he was alarmed to discover that the relatively small Dole VA had one of the most expensive cardiac programs in the country. As Ament dug deeper, he realized vascular interventions were the reason.
“It just did not make sense that the acuity level of our patients would generate such extreme cost variances from the norm,” he testified in December, in a deposition for the whistleblower case. “It was so significant, we needed to get to the bottom of it.”
Ament, a second generation Air Force veteran, quietly assembled a task force to investigate why the facility had purchased so many medical devices for these procedures. After they examined inventory records, calculating the total number of medical devices and the cost of devices per patient, they grew concerned.
“We were more expensive than, I believe it was, the top 10 hospitals in the VA combined,” he said. “My feeling was that we either had very, very bad providers or we had product walking out the door.”
Ament enlisted experts from other VA hospitals to help his team investigate, including an administrative officer who could understand finances and a respected interventional radiologist who could examine records. The task force gathered a list of patients from 2016 to 2018, according to internal emails, and analyzed their medical charts.
According to internal VA documents released through the whistleblower suit, the review found a number of clinical failings: Evidence-based medicine had not been followed in the majority of cases reviewed. Procedures were over-aggressive, treating lesions that should have been left alone. And there was a total disregard for established best practices for treating peripheral artery disease.
One of the experts on the investigative team explained to Ament that while it was not uncommon for doctors to use a couple of devices in one intervention, the total number of devices in many of the procedures at his facility went into the double digits, sometimes five times the expected amount.
In one encounter, a doctor deployed 33 devices in one procedure – 3 atherectomy devices, 9 stents, and 21 balloons.
This use of devices was exorbitant, Ament came to understand. “I want to say the term ‘egregious’ was used,” he testified. “It was kind of like validation, but I really wish I was wrong.”
“Did it make you concerned for patient care?” a lawyer asked during the deposition.
“It did,” Ament replied.
A member of his task force pulled data for veterans who had leg amputations due to vascular disease. Over 5 years, the number of veterans who had amputations increased, from about 6 in 2013 to 38 in 2018, according to internal emails released in the suit. The VA did not respond to ProPublica’s questions about the rise in amputations or whether it was due to complications from the procedures.
Even though Ament testified in December 2022 that he became aware of the excessive use of devices during his investigation that began about 5 years ago, neither he nor the VA have publicly acknowledged these findings outside of the lawsuit. It is unclear whether VA representatives informed the patients whose records were reviewed about their findings. ProPublica reached out to more than half a dozen veteran community groups in the Wichita area and none were aware of the investigation nor the allegations of overuse of vascular procedures at the facility.
The VA says that if its ongoing review finds instances of substandard care, it will reach out to affected patients and inform them about possible complications and benefits they may be entitled to. The press secretary said the review will take several months. Ament declined to respond to ProPublica’s questions, citing the ongoing case.
In 2018, Ament turned over his findings to the criminal division of the VA’s Office of Inspector General. He also shut down interventional radiology procedures at the facility’s catheter lab.
Federal agents separately opened an investigation into the same unit in the facility, looking into allegations of kickbacks.
More than 40 pages of expense reports from Medtronic, revealed in the whistleblower case, show sales representatives treating Dole health care workers to hundreds of meals over several years – lunches at Dempsey’s Biscuit Co.; business meals at the Scotch & Sirloin steakhouse; dinner at Chester’s Chophouse & Wine Bar, price per attendee: $122.39.
Federal agents obtained the receipts.
“Robert J. Dole VAMC employees may have received improper gratuities, in the forms of paid lunches, dinners, etc., from sales representatives from Medtronic,” Nathen Howard, a special agent in the VA OIG, wrote in an investigation memo from February 2019.
This kind of relationship could violate VA policy, which forbids federal employees from receiving any gifts, including meals, from people who do business or seek to do business with a federal institution. For health care workers, violating this policy could have serious implications for patients. Numerous studies have shown that even modest industry-sponsored gifts, including meals, may influence prescribing or treatment behavior of health care professionals.
The agents opened their investigation into kickbacks at the Wichita facility in response to the whistleblower lawsuit, which was filed by Thomas Schroeder in 2017. The VA OIG would not confirm or deny whether it was continuing to investigate kickbacks at the facility. The VA did not directly answer ProPublica’s questions about kickbacks at the Dole VA, but it said that every employee must complete an annual ethics training, which covers gift rules.
In recent years, Medtronic has settled a handful of other cases that have alleged kickbacks between company representatives and health care professionals.
In 2018, Medtronic’s subsidiary Covidien paid $13 million to settle claims with the U.S. Department of Justice that it paid kickbacks to health care institutions that used its mechanical blood clot devices. In 2019, the same subsidiary paid $17 million to resolve allegations that it provided in-kind marketing support to doctors using its vein products. And in 2020, Medtronic paid more than $8 million to settle claims that representatives had paid kickbacks to a neurosurgeon, including scores of lavish meals at a restaurant that the doctor owned, to induce him to purchase the company’s medication pumps.
Schroeder’s lawsuit is not the first time Medtronic’s vascular devices were named in an alleged kickback scheme. In early 2015, Medtronic acquired Covidien, and shortly after the merger, its subsidiary ev3 Inc. agreed to pay $1.25 million to resolve allegations that it had paid doctors who were “high volume users” of its atherectomy devices to act as evangelists for the company, and had provided physicians with company shares to participate in clinical trials for their tools.
The whistleblower in this earlier case, a former sales representative for the company, also alleged that the subsidiary was gaming Medicare’s payment system. Hospitals were often hesitant to conduct atherectomy procedures because of the low reimbursement rates. According to the suit, sales representatives encouraged doctors to admit patients for longer stays to reap greater reimbursements and make a profit, even though such stays were often not medically indicated.
“Medical device makers that try to boost their profits by causing patients to be admitted for unnecessary and expensive inpatient hospital stays will be held accountable,” special agent Thomas O’Donnell, from the Office of Inspector General at the U.S. Department of Health and Human Services, said in a press release for the settlement. “Both patients and taxpayers deserve to have medical decisions made based on what is medically appropriate.”
Medtronic spokesperson Xiong said that in each case, the company “cooperated fully with the DOJ to resolve its concerns and, where wrongdoing was found, took appropriate remedial action.”
Seton Hall Law School professor Jacob Elberg, a former assistant U.S. attorney for the District of New Jersey who led its health care and government fraud unit, is concerned by the frequency of such settlements in the last 2 decades. “There are, at this point, real questions as to whether the sanctions imposed by DOJ are sufficient to deter wrongdoing and to lead to meaningful change, especially within the medical device industry.”
Although the Department of Justice has declined to intervene in the lawsuit involving the Dole VA at this time, the case is ongoing and further depositions with Medtronic sales representatives and a former VA employee are scheduled for this month.
VA employees and doctors named in the suit declined to comment or did not respond to ProPublica’s questions about the alleged kickbacks and whether sales representatives may have influenced veterans’ treatment plans. In interviews with federal investigators, according to released transcripts, several of the employees who were questioned denied receiving frequent meals from sales representatives, contradicting Medtronic’s expense reports.
Their statements also stand in contrast to Medtronic representative Kari Kirk’s final text messages during that procedure in June 2017, which ultimately lasted more than 3 hours.
“Now u done??” her colleague asked.
“Just finished,” she texted. “Running to get them lunch!”

The lawsuit comes amid growing concern about one of these procedures – atherectomies – after researchers and doctors have uncovered patterns of excessive and inappropriate use. Recent research has found that this procedure, a common but costly treatment to shave or laser plaque from blood vessels, is not more effective than cheaper alternatives and may even be associated with a higher risk of complications including amputation. In recent years, several doctors and clinics have been investigated for allegedly taking advantage of Medicare’s reimbursement rates, and one study found that many doctors are resorting to atherectomies in the earliest stages of peripheral artery disease, against best practices that urge noninvasive treatment.
“Atherectomy is important in certain settings. But it’s being used in a way that is entirely inappropriate and it’s largely driven by the incentive structure,” said Dr. Caitlin Hicks, the lead author of the study and an associate professor of surgery at Johns Hopkins University School of Medicine.
Although different payment structures govern the care of veterans, the whistleblower lawsuit alleges that outside physicians, paid hourly by the Dole VA, were motivated to conduct longer and more complex procedures that would earn them higher payment.
Under different circumstances, the patient in the procedure room on that summer day could have been done after 2 hours.
But, 150 minutes in, those Medtronic representatives were still texting. At that point, more than 15 of their vascular devices had been used, including stents, balloons, and those for atherectomy.
“Long case!” Kirk’s colleague texted. “Is it looking ok??”
“It is,” she said. “Thought we were done a few times! Now he’s going back in to cut again!”
A little while later, she texted: “....17!”
He texted back [with laughing emoticons].
Hospital leaders had been scrutinizing the use of these procedures at the Dole VA for years.
In 2017, shortly after Rick Ament was hired to lead the facility, he noticed something was amiss. While the longtime hospital administrator was poring over the finances, he was alarmed to discover that the relatively small Dole VA had one of the most expensive cardiac programs in the country. As Ament dug deeper, he realized vascular interventions were the reason.
“It just did not make sense that the acuity level of our patients would generate such extreme cost variances from the norm,” he testified in December, in a deposition for the whistleblower case. “It was so significant, we needed to get to the bottom of it.”
Ament, a second generation Air Force veteran, quietly assembled a task force to investigate why the facility had purchased so many medical devices for these procedures. After they examined inventory records, calculating the total number of medical devices and the cost of devices per patient, they grew concerned.
“We were more expensive than, I believe it was, the top 10 hospitals in the VA combined,” he said. “My feeling was that we either had very, very bad providers or we had product walking out the door.”
Ament enlisted experts from other VA hospitals to help his team investigate, including an administrative officer who could understand finances and a respected interventional radiologist who could examine records. The task force gathered a list of patients from 2016 to 2018, according to internal emails, and analyzed their medical charts.
According to internal VA documents released through the whistleblower suit, the review found a number of clinical failings: Evidence-based medicine had not been followed in the majority of cases reviewed. Procedures were over-aggressive, treating lesions that should have been left alone. And there was a total disregard for established best practices for treating peripheral artery disease.
One of the experts on the investigative team explained to Ament that while it was not uncommon for doctors to use a couple of devices in one intervention, the total number of devices in many of the procedures at his facility went into the double digits, sometimes five times the expected amount.
In one encounter, a doctor deployed 33 devices in one procedure – 3 atherectomy devices, 9 stents, and 21 balloons.
This use of devices was exorbitant, Ament came to understand. “I want to say the term ‘egregious’ was used,” he testified. “It was kind of like validation, but I really wish I was wrong.”
“Did it make you concerned for patient care?” a lawyer asked during the deposition.
“It did,” Ament replied.
A member of his task force pulled data for veterans who had leg amputations due to vascular disease. Over 5 years, the number of veterans who had amputations increased, from about 6 in 2013 to 38 in 2018, according to internal emails released in the suit. The VA did not respond to ProPublica’s questions about the rise in amputations or whether it was due to complications from the procedures.
Even though Ament testified in December 2022 that he became aware of the excessive use of devices during his investigation that began about 5 years ago, neither he nor the VA have publicly acknowledged these findings outside of the lawsuit. It is unclear whether VA representatives informed the patients whose records were reviewed about their findings. ProPublica reached out to more than half a dozen veteran community groups in the Wichita area and none were aware of the investigation nor the allegations of overuse of vascular procedures at the facility.
The VA says that if its ongoing review finds instances of substandard care, it will reach out to affected patients and inform them about possible complications and benefits they may be entitled to. The press secretary said the review will take several months. Ament declined to respond to ProPublica’s questions, citing the ongoing case.
In 2018, Ament turned over his findings to the criminal division of the VA’s Office of Inspector General. He also shut down interventional radiology procedures at the facility’s catheter lab.
Federal agents separately opened an investigation into the same unit in the facility, looking into allegations of kickbacks.
More than 40 pages of expense reports from Medtronic, revealed in the whistleblower case, show sales representatives treating Dole health care workers to hundreds of meals over several years – lunches at Dempsey’s Biscuit Co.; business meals at the Scotch & Sirloin steakhouse; dinner at Chester’s Chophouse & Wine Bar, price per attendee: $122.39.
Federal agents obtained the receipts.
“Robert J. Dole VAMC employees may have received improper gratuities, in the forms of paid lunches, dinners, etc., from sales representatives from Medtronic,” Nathen Howard, a special agent in the VA OIG, wrote in an investigation memo from February 2019.
This kind of relationship could violate VA policy, which forbids federal employees from receiving any gifts, including meals, from people who do business or seek to do business with a federal institution. For health care workers, violating this policy could have serious implications for patients. Numerous studies have shown that even modest industry-sponsored gifts, including meals, may influence prescribing or treatment behavior of health care professionals.
The agents opened their investigation into kickbacks at the Wichita facility in response to the whistleblower lawsuit, which was filed by Thomas Schroeder in 2017. The VA OIG would not confirm or deny whether it was continuing to investigate kickbacks at the facility. The VA did not directly answer ProPublica’s questions about kickbacks at the Dole VA, but it said that every employee must complete an annual ethics training, which covers gift rules.
In recent years, Medtronic has settled a handful of other cases that have alleged kickbacks between company representatives and health care professionals.
In 2018, Medtronic’s subsidiary Covidien paid $13 million to settle claims with the U.S. Department of Justice that it paid kickbacks to health care institutions that used its mechanical blood clot devices. In 2019, the same subsidiary paid $17 million to resolve allegations that it provided in-kind marketing support to doctors using its vein products. And in 2020, Medtronic paid more than $8 million to settle claims that representatives had paid kickbacks to a neurosurgeon, including scores of lavish meals at a restaurant that the doctor owned, to induce him to purchase the company’s medication pumps.
Schroeder’s lawsuit is not the first time Medtronic’s vascular devices were named in an alleged kickback scheme. In early 2015, Medtronic acquired Covidien, and shortly after the merger, its subsidiary ev3 Inc. agreed to pay $1.25 million to resolve allegations that it had paid doctors who were “high volume users” of its atherectomy devices to act as evangelists for the company, and had provided physicians with company shares to participate in clinical trials for their tools.
The whistleblower in this earlier case, a former sales representative for the company, also alleged that the subsidiary was gaming Medicare’s payment system. Hospitals were often hesitant to conduct atherectomy procedures because of the low reimbursement rates. According to the suit, sales representatives encouraged doctors to admit patients for longer stays to reap greater reimbursements and make a profit, even though such stays were often not medically indicated.
“Medical device makers that try to boost their profits by causing patients to be admitted for unnecessary and expensive inpatient hospital stays will be held accountable,” special agent Thomas O’Donnell, from the Office of Inspector General at the U.S. Department of Health and Human Services, said in a press release for the settlement. “Both patients and taxpayers deserve to have medical decisions made based on what is medically appropriate.”
Medtronic spokesperson Xiong said that in each case, the company “cooperated fully with the DOJ to resolve its concerns and, where wrongdoing was found, took appropriate remedial action.”
Seton Hall Law School professor Jacob Elberg, a former assistant U.S. attorney for the District of New Jersey who led its health care and government fraud unit, is concerned by the frequency of such settlements in the last 2 decades. “There are, at this point, real questions as to whether the sanctions imposed by DOJ are sufficient to deter wrongdoing and to lead to meaningful change, especially within the medical device industry.”
Although the Department of Justice has declined to intervene in the lawsuit involving the Dole VA at this time, the case is ongoing and further depositions with Medtronic sales representatives and a former VA employee are scheduled for this month.
VA employees and doctors named in the suit declined to comment or did not respond to ProPublica’s questions about the alleged kickbacks and whether sales representatives may have influenced veterans’ treatment plans. In interviews with federal investigators, according to released transcripts, several of the employees who were questioned denied receiving frequent meals from sales representatives, contradicting Medtronic’s expense reports.
Their statements also stand in contrast to Medtronic representative Kari Kirk’s final text messages during that procedure in June 2017, which ultimately lasted more than 3 hours.
“Now u done??” her colleague asked.
“Just finished,” she texted. “Running to get them lunch!”

Diabetes drug tied to lower dementia risk
new research suggests.
Overall, in a large cohort study from South Korea, patients who took pioglitazone were 16% less likely to develop dementia over an average of 10 years than peers who did not take the drug.
However, the dementia risk reduction was 54% among those with ischemic heart disease and 43% among those with a history of stroke.
“Our study was to see the association between pioglitazone use and incidence of dementia, not how (with what mechanisms) this drug can suppress dementia pathology,” coinvestigator Eosu Kim, MD, PhD, Yonsei University, Seoul, South Korea, said in an interview.
However, “as we found this drug is more effective in diabetic patients who have blood circulation problems in the heart or brain than in those without such problems, we speculate that pioglitazone’s antidementia action may be related to improving blood vessel’s health,” Dr. Kim said.
This finding suggests that pioglitazone could be used as a personalized treatment approach for dementia prevention in this subgroup of patients with diabetes, the researchers noted.
The results were published online in Neurology.
Dose-response relationship
Risk for dementia is doubled in adults with T2DM, the investigators wrote. Prior studies have suggested that pioglitazone may protect against dementia, as well as a first or recurrent stroke, in patients with T2DM.
This led Dr. Kim and colleagues to examine the effects of pioglitazone on dementia risk overall and in relation to stroke and ischemic heart disease.
Using the national Korean health database, the researchers identified 91,218 adults aged 50 and older with new-onset T2DM who did not have dementia. A total of 3,467 were treated with pioglitazone.
Pioglitazone exposure was defined as a total cumulative daily dose of 90 or more calculated from all dispensations during 4 years after T2DM diagnosis, with outcomes assessed after this period.
Over an average of 10 years, 8.3% of pioglitazone users developed dementia, compared with 10.0% of nonusers.
There was a statistically significant 16% lower risk for developing all-cause dementia among pioglitazone users than among nonusers (adjusted hazard ratio, 0.84; 95% confidence interval, 0.75-0.95).
A dose-response relationship was evident; pioglitazone users who received the highest cumulative daily dose were at lower risk for dementia (aHR, 0.72; 95% CI, 0.55-0.94).
Several limitations
The reduced risk for dementia was more pronounced among patients who used pioglitazone for 4 years in comparison with patients who did not use the drug (aHR, 0.63; 95% CI, 0.44-0.90).
The apparent protective effect of pioglitazone with regard to dementia was greater among those with a history of ischemic heart disease (aHR, 0.46; 95% CI, 0.24-0.90) or stroke (aHR, 0.57; 95% CI, 0.38-0.86) before diabetes diagnosis.
The incidence of stroke was also reduced with pioglitazone use (aHR, 0.81; 95% CI, 0.66-1.0).
“These results provide valuable information on who could potentially benefit from pioglitazone use for prevention of dementia,” Dr. Kim said in a news release.
However, “the risk and benefit balance of long-term use of this drug to prevent dementia should be prospectively assessed,” he said in an interview.
The researchers cautioned that the study was observational; hence, the reported associations cannot address causal relationships. Also, because of the use of claims data, drug compliance could not be guaranteed, and exposure may have been overestimated.
There is also the potential for selection bias, and no information on apolipoprotein E was available, they noted.
More data needed
In an accompanying editorial, Colleen J. Maxwell, PhD, University of Waterloo (Ont.), and colleagues wrote that the results “not only support previous studies showing the potential cognitive benefit of pioglitazone but also extend our understanding of this benefit through the mediating effect of reducing ischemic stroke.”
However, because of their associated risks, which include fractures, weight gain, heart failure, and bladder cancer, thiazolidinediones are not currently favored in diabetes management guidelines – and their use has significantly declined since the mid to late 2000s, the editorialists noted.
They agreed that it will be important to reassess the risk-benefit profile of pioglitazone in T2DM as additional findings emerge.
They also noted that sodium-glucose cotransporter-2 inhibitors, which have significant cardiovascular and renal benefits and minimal side effects, may also lower the risk for dementia.
“As both pioglitazone and SGLT-2 inhibitors are second-line options for physicians, the current decision would easily be in favor of SGLT-2 inhibitors given their safety profile,” Dr. Maxwell and colleagues wrote.
For now, pioglitazone “should not be used to prevent dementia in patients with T2DM,” they concluded.
The study was supported by grants from the National Research Foundation of Korea funded by the Korean government and the Ministry of Health and Welfare. The investigators and editorialists report no relevant financial relationships.

New tool better estimates cardiovascular risk in people with lupus
Current risk estimators are inaccurate
A tool that incorporates lupus-related variables with traditional risk factors provides a much more accurate assessment of cardiovascular (CV) risk in patients with systemic lupus erythematosus (SLE), according to data presented at the annual meeting of the Canadian Rheumatology Association.
In the initial clinical assessment of this tool, called the SLECRISK, “it identified high-risk lupus patients who would otherwise be missed by traditional methods of CV risk assessment,” reported May Y. Choi, MD, associate director of translational research at the University of Calgary’s (Alta.) Lupus Centre of Excellence.
It is well known that patients with SLE face an increased risk of CV events starting at an age long before risk begins climbing in the general population, according to Dr. Choi. She cited one study that showed women aged 35-44 years have a 50-fold greater risk of myocardial infarction than healthy individuals.
All major guidelines recognize this increased risk and recommend CV risk assessment in patients with SLE, even though Dr. Choi pointed out that traditional tools, such as the American College of Cardiology atherosclerotic cardiovascular disease (ASCVD) risk calculator or the Framingham Risk Score (FRS) have a limited ability to detect the patients with SLE who are most likely to have an event.
In SLE, current tools are inadequate
“These risk assessment tools perform poorly in SLE patients because they do not capture SLE-related inflammation,” Dr. Choi said. Of several examples, Dr. Choi cited a study showing “seven times more MIs and strokes observed than expected in SLE patients on the basis of the FRS.”
The disparity between expected and observed MIs and strokes is worse with increasing severity of SLE. In a study she presented 3 years ago, rates of CV events were 12 times higher in those with inactive or mild SLE, rising to a 16-fold increase among those with moderate disease and jumping to a 32-fold increase in those with severe SLE.
The SLECRISK tool was developed from the Brigham and Women’s Hospital SLE Registry, which was initiated in 1992. Patients without a history of CV disease were evaluated for traditional CV risk factors and for SLE-specific characteristics such as disease activity, levels of the complement proteins C3 and C4, kidney function, the presence of nephritis, and SLE duration. The value of these characteristics as predictors of CV events were then assessed over a 10-year follow-up period before being assembled into the SLECRISK tool.
In an example of the risk equation, Dr. Choi described a 50-year-old patient with SLE and a 5% 10-year ASCVD risk score, which is low. After adjustment for SLE risks, which included 10 years disease duration, high disease activity, elevated creatinine, and positive anti–double stranded DNA status, the 10-year CV risk score climbed to 16.2%, which is moderate.
The performance of the SLECRISK was evaluated in 1,243 patients providing 8,946.51 person-years of follow-up. During this period, there were 90 major adverse cardiac events (MACE), of which 82% were adjudicated by cardiologists, and 211 secondary events.
Relative to the ASCVD risk score, the SLECRISK identified about twice as many patients with SLE as having moderate risk and 3.5-fold more patients as having high risk. Among patients who experienced CV events, traditional CV risk factors were more common but so were SLE-specific risk factors, including greater disease severity, a greater likelihood of lupus nephritis, increased complement levels, and greater exposure to glucocorticoids, according to Dr. Choi.
Specificities for CV events higher on SLECRISK
In predicting CV events, the differences in specificities were in the same general range, although somewhat higher for the ASCVD risk score in regard to predicting MACE (83% vs. 72%) and MACE plus secondary events (90% vs. 79%). However, the sensitivities were much higher for SLECRISK relative to the ASCVD risk score for MACE alone (64% vs. 41%) and for MACE plus secondary events (58% vs. 35%).
When comparing those who had an MI or stroke, the ASCVD risk score identified 8 (7%) patients missed by SLECRISK, whereas SLECRISK identified 89 (73%) missed by the ASCVD risk score. The remaining 25 patients (20%) were identified by both. The advantage of SLECRISK was similar for MACE plus secondary outcomes.
Dr. Choi noted that all of the SLE-specific variables in SLECRISK are readily obtained and often already available in patient charts. She said that there is a plan to validate the tool in larger groups, but with a goal of creating a tool available online for clinicians and their patients to use. There is also an even more ambitious plan for the future.
“We have funding to look at machine learning to evaluate predictive variables in SLE patients,” Dr. Choi said. Rather than adding SLE-specific variables to traditional risks, the plan is to “start from scratch,” letting artificial intelligence assemble predictors without prejudice to what might or might not be relevant.
A SLE-specific tool for evaluating CV risk is an important “unmet need,” according to Karen H. Costenbader, MD, professor in the division of rheumatology, inflammation, and immunity at Brigham and Women’s Hospital and Harvard Medical School, both in Boston. In an interview, she reiterated that measuring CV risk in SLE is already guideline recommended, but conventional tools have been shown to be inaccurate.
“I can envision it being used in clinical encounters to help guide shared decision-making with patients,” explained Dr. Costenbader, who was not involved in the presentation at the CRA meeting but worked with Dr. Choi in developing SLECRISK. “It would give us more precise estimates, allowing us to risk stratify our patients and informing us as to which modifiable SLE-specific and nonspecific factors are contributing most to CV risk.’
The problem of using conventional risk assessments in SLE has been well recognized. Of those who have written on this subject, Maureen McMahon, MD, site director of the Lupus Clinical Trials Network at the University of California, Los Angeles, said: “There is a critical need for the development of SLE-specific risk assessment tools like SLECRISK.”
Author of several studies looking at alternatives for CV risk assessment in SLE, including a study looking at a panel of biomarkers that was published in ACR Open Rheumatology, Dr. McMahon said in an interview that CV risk in SLE is high but conventional risk assessments are flawed.
“Multiple previous studies have demonstrated that these currently available calculators are not adequate for identifying risk in the lupus patient population,” she said. According to Dr. McMahon, the fact that rheumatologists remain “dependent upon [these conventional] cardiovascular risk calculators” is a well-recognized problem that needs resolution.
Dr. Choi has financial relationships with AstraZeneca, GlaxoSmithKline, Mallinckrodt. MitogenDx, Organon, and Werfen International. Dr. Costenbader reports no potential conflicts of interest. Dr. McMahon has financial relationships with AstraZeneca, Aurinia Pharmaceuticals, Eli Lilly, and GlaxoSmithKline.

The disparity between expected and observed MIs and strokes is worse with increasing severity of SLE. In a study she presented 3 years ago, rates of CV events were 12 times higher in those with inactive or mild SLE, rising to a 16-fold increase among those with moderate disease and jumping to a 32-fold increase in those with severe SLE.
The SLECRISK tool was developed from the Brigham and Women’s Hospital SLE Registry, which was initiated in 1992. Patients without a history of CV disease were evaluated for traditional CV risk factors and for SLE-specific characteristics such as disease activity, levels of the complement proteins C3 and C4, kidney function, the presence of nephritis, and SLE duration. The value of these characteristics as predictors of CV events were then assessed over a 10-year follow-up period before being assembled into the SLECRISK tool.
In an example of the risk equation, Dr. Choi described a 50-year-old patient with SLE and a 5% 10-year ASCVD risk score, which is low. After adjustment for SLE risks, which included 10 years disease duration, high disease activity, elevated creatinine, and positive anti–double stranded DNA status, the 10-year CV risk score climbed to 16.2%, which is moderate.
The performance of the SLECRISK was evaluated in 1,243 patients providing 8,946.51 person-years of follow-up. During this period, there were 90 major adverse cardiac events (MACE), of which 82% were adjudicated by cardiologists, and 211 secondary events.
Relative to the ASCVD risk score, the SLECRISK identified about twice as many patients with SLE as having moderate risk and 3.5-fold more patients as having high risk. Among patients who experienced CV events, traditional CV risk factors were more common but so were SLE-specific risk factors, including greater disease severity, a greater likelihood of lupus nephritis, increased complement levels, and greater exposure to glucocorticoids, according to Dr. Choi.
Specificities for CV events higher on SLECRISK
In predicting CV events, the differences in specificities were in the same general range, although somewhat higher for the ASCVD risk score in regard to predicting MACE (83% vs. 72%) and MACE plus secondary events (90% vs. 79%). However, the sensitivities were much higher for SLECRISK relative to the ASCVD risk score for MACE alone (64% vs. 41%) and for MACE plus secondary events (58% vs. 35%).
When comparing those who had an MI or stroke, the ASCVD risk score identified 8 (7%) patients missed by SLECRISK, whereas SLECRISK identified 89 (73%) missed by the ASCVD risk score. The remaining 25 patients (20%) were identified by both. The advantage of SLECRISK was similar for MACE plus secondary outcomes.
Dr. Choi noted that all of the SLE-specific variables in SLECRISK are readily obtained and often already available in patient charts. She said that there is a plan to validate the tool in larger groups, but with a goal of creating a tool available online for clinicians and their patients to use. There is also an even more ambitious plan for the future.
“We have funding to look at machine learning to evaluate predictive variables in SLE patients,” Dr. Choi said. Rather than adding SLE-specific variables to traditional risks, the plan is to “start from scratch,” letting artificial intelligence assemble predictors without prejudice to what might or might not be relevant.
A SLE-specific tool for evaluating CV risk is an important “unmet need,” according to Karen H. Costenbader, MD, professor in the division of rheumatology, inflammation, and immunity at Brigham and Women’s Hospital and Harvard Medical School, both in Boston. In an interview, she reiterated that measuring CV risk in SLE is already guideline recommended, but conventional tools have been shown to be inaccurate.
“I can envision it being used in clinical encounters to help guide shared decision-making with patients,” explained Dr. Costenbader, who was not involved in the presentation at the CRA meeting but worked with Dr. Choi in developing SLECRISK. “It would give us more precise estimates, allowing us to risk stratify our patients and informing us as to which modifiable SLE-specific and nonspecific factors are contributing most to CV risk.’
The problem of using conventional risk assessments in SLE has been well recognized. Of those who have written on this subject, Maureen McMahon, MD, site director of the Lupus Clinical Trials Network at the University of California, Los Angeles, said: “There is a critical need for the development of SLE-specific risk assessment tools like SLECRISK.”
Author of several studies looking at alternatives for CV risk assessment in SLE, including a study looking at a panel of biomarkers that was published in ACR Open Rheumatology, Dr. McMahon said in an interview that CV risk in SLE is high but conventional risk assessments are flawed.
“Multiple previous studies have demonstrated that these currently available calculators are not adequate for identifying risk in the lupus patient population,” she said. According to Dr. McMahon, the fact that rheumatologists remain “dependent upon [these conventional] cardiovascular risk calculators” is a well-recognized problem that needs resolution.
Dr. Choi has financial relationships with AstraZeneca, GlaxoSmithKline, Mallinckrodt. MitogenDx, Organon, and Werfen International. Dr. Costenbader reports no potential conflicts of interest. Dr. McMahon has financial relationships with AstraZeneca, Aurinia Pharmaceuticals, Eli Lilly, and GlaxoSmithKline.
A tool that incorporates lupus-related variables with traditional risk factors provides a much more accurate assessment of cardiovascular (CV) risk in patients with systemic lupus erythematosus (SLE), according to data presented at the annual meeting of the Canadian Rheumatology Association.
In the initial clinical assessment of this tool, called the SLECRISK, “it identified high-risk lupus patients who would otherwise be missed by traditional methods of CV risk assessment,” reported May Y. Choi, MD, associate director of translational research at the University of Calgary’s (Alta.) Lupus Centre of Excellence.
It is well known that patients with SLE face an increased risk of CV events starting at an age long before risk begins climbing in the general population, according to Dr. Choi. She cited one study that showed women aged 35-44 years have a 50-fold greater risk of myocardial infarction than healthy individuals.
All major guidelines recognize this increased risk and recommend CV risk assessment in patients with SLE, even though Dr. Choi pointed out that traditional tools, such as the American College of Cardiology atherosclerotic cardiovascular disease (ASCVD) risk calculator or the Framingham Risk Score (FRS) have a limited ability to detect the patients with SLE who are most likely to have an event.
In SLE, current tools are inadequate
“These risk assessment tools perform poorly in SLE patients because they do not capture SLE-related inflammation,” Dr. Choi said. Of several examples, Dr. Choi cited a study showing “seven times more MIs and strokes observed than expected in SLE patients on the basis of the FRS.”

Meta-analysis throws more shade aspirin’s way
A new meta-analysis has added evidence questioning the utility and efficacy of prophylactic low-dose aspirin for preventing cardiovascular events in people who don’t have atherosclerotic cardiovascular disease (ASCVD), whether or not they’re also taking statins, and finds that at every level of ASCVD risk the aspirin carries a risk of major bleeding that exceeds its potentially protective benefits.
In a study published online in JACC: Advances, the researchers, led by Safi U. Khan, MD, MS, analyzed data from 16 trials with 171,215 individuals, with a median age of 64 years. Of the population analyzed, 35% were taking statins.
“This study focused on patients without ASCVD who are taking aspirin with or without statin therapy to prevent ASCVD events,” Dr. Khan, a cardiovascular disease fellow at Houston Methodist DeBakey Heart and Vascular Institute, told this news organization. “We noted that the absolute risk of major bleeding in this patient population exceeds the absolute reduction in MI by aspirin across different ASCVD risk categories. Furthermore, concomitant statin therapy use further diminishes aspirin’s cardiovascular effects without influencing bleeding risk.”
Across the 16 studies, people taking aspirin had a relative risk reduction of 15% for MI vs. controls (RR .85; 95% confidence interval [CI], .77 to .95; P < .001). However, they had a 48% greater risk of major bleeding (RR, 1.48; 95% CI, 1.31-1.66; P < .001).
The meta-analysis also found that aspirin, either as monotherapy or with a statin, carried a slight to significant benefit depending on the estimated risk of developing ASCVD. The risk of major bleeding exceeded the benefit across all three risk-stratified groups. The greatest benefit, and greatest risk, was in the groups with high to very-high ASCVD risk groups, defined as a 20%-30% and 30% or greater ASCVD risk, respectively: 20-37 fewer MIs per 10,000 with monotherapy and 27-49 fewer with statin, but 78-98 more major bleeding events with monotherapy and 74-95 more with statin.
And aspirin, either as monotherapy or with statin, didn’t reduce the risk of other key endpoints: stroke, all-cause mortality, or cardiovascular mortality. While aspirin was associated with a lower risk of nonfatal MI (RR, .82; 95% CI, .72 to .94; P ≤. 001), it wasn’t associated with reducing the risk of nonfatal stroke. Aspirin patients had a significantly 32% greater risk of intracranial hemorrhage (RR, 1.32; 95% CI, 1.12-1.55; P ≤ .001) and 51% increased risk of gastrointestinal bleeding (RR, 1.51; 95% CI, 1.33-1.72; P ≤ .001).
“We used randomized data from all key primary prevention of aspirin trials and estimated the absolute effects of aspirin therapy with or without concomitant statin across different baseline risks of the patients,” Dr. Khan said. “This approach allowed us to identify aspirin therapy’s risk-benefit equilibrium, which is tilted towards more harm than benefit.”
He acknowledged study limitations included using study-level rather than patient-level meta-analysis, and the inability to calculate effects in younger populations at high absolute risk.
The investigators acknowledged the controversy surrounding aspirin use to prevent ASCVD, noting the three major guidelines: the 2019 American College of Cardiology/American Heart Association and the 2021 European Society of Cardiology guidelines for aspirin only among asymptomatic individuals with high risk of ASCVD events, low bleeding risk, and age 70 years and younger; and the United States Preventive Services Task Force guidelines, updated in 2022, recommending individualized low-dose aspirin only among adults ages 40-59 years with 10-year ASCVD risk of 10% or greater and a low bleeding risk.
The findings are not a clarion call to halt aspirin therapy, Dr. Khan said. “This research focuses only on patients who do not have ASCVD,” he said. “Patients who do have ASCVD should continue with aspirin and statin therapy. However, we noted that aspirin has a limited role for patients who do not have ASCVD beyond lifestyle modifications, smoking cessation, exercise, and preventive statin therapy. Therefore, they should only consider using aspirin if their physicians suggest that the risk of having a cardiovascular event exceeds their bleeding risk. Otherwise, they should discuss with their physicians about omitting aspirin.”
The study confirms the move away from low-dose aspirin to prevent ASCVD, said Tahmid Rahman, MD, cardiologist and associate director of the Center for Advanced Lipid Management at Stony Brook (N.Y.) Heart Institute. “The study really continues to add to essentially what we already know,” he said. “There was a big push that aspirin, initially before the major statin trials, was the way to go to prevent heart disease, but with later studies, and especially now with newer antiplatelet therapies and longer duration of medication for people with both secondary prevention and primary prevention, we are getting away from routine aspirin, especially in primary prevention.”
Lowering LDL cholesterol is the definitive target for lowering risk for MI and stroke, Dr. Rahman said. “Statins don’t lead to a bleeding risk,” he said, “so my recommendation is to be aggressive with lowering your cholesterol and getting the LDL as low possible to really reduce outcomes, especially in secondary prevention, as well as in high-risk patients for primary prevention, especially diabetics.”
He added, however, lifestyle modification also has a key role for preventing ASCVD. “No matter what we have with medication, the most important thing is following a proper diet, especially something like the Mediterranean diet, as well as exercising regularly,” he said.
Dr. Khan and Dr. Rahman have no relevant disclosures.

Guidance for PCI without on-site surgical backup updated
such as ambulatory surgery centers (ASCs) and office-based laboratories and which are best left to more traditional settings, such as hospitals with full cardiac support.
PCI has evolved quickly since SCAI issued its last update almost 9 years ago. The updated statement, published online in the Journal of the Society for Cardiovascular Angiography and Interventions, notes that the proportion of same-day PCI discharges has increased from 4.5% in 2009 to 28.6% in 2017.
The statement also notes that the Medicare facility fee for outpatient PCI in an ASC is about 40% less than the hospital fee: $6,111 versus $10,258 for the facility fee for 2022. The Centers for Medicare & Medicaid Services in 2020 extended coverage for PCIs in ASCs.
Rationale for update
Writing group chair Cindy Grines, MD, explained the rationale for updating the statement now. “The 2014 SCAI statement was very conservative, recommending only the simplest of cases be done without surgical backup,” Dr. Grines, chief scientific officer at Northside Hospital Cardiovascular Institute in Atlanta, said in an interview.
The statement drew on 12 global studies from 2015 to 2022 that evaluated more than 8 million PCIs at facilities with and without surgery on site. Dr. Grines noted those studies reported complication rates as low as 0.1% in PCI procedures in centers without surgical backup.
She also noted that the writing committee also received input that “by restricting the use of certain devices such as atherectomy, some patients who needed it as a bailout could be harmed.”
Another factor in prompting the statement update, Dr. Grines said: “Many hospitals have consolidated into heath systems, and these systems consolidated bypass surgery into one center. Therefore, centers with high volume, experienced operators, and excellent outcomes were now left with no surgery on site. It didn’t make sense to withdraw complex PCI from these centers who haven’t sent a patient for emergency bypass in several years.”
Statement guidance
The centerpiece of the update is an algorithm that covers the range of settings for PCI, from having a surgeon on site to ACS or office-based lab.
For example, indications for on-site surgical capability are PCI of the last remaining patent vessel or retrograde approach to epicardial chronic total occlusion (CTO), and when the patient is a candidate for surgery.
Indications for PCI in a hospital without on-site surgery but with percutaneous ventricular assist device or extracorporeal membrane oxygenation, calcium modification devices and high PCI volume are patients with decreased left ventricular ejection fraction, unprotected left main artery, CTO, or degenerated vein grafts.
For patients at high risk for transfusion, acute kidney injury or vascular complications, or who have high baseline respiratory risk, a hospital without on-site surgery but with respiratory care, blood bank, and vascular surgery services is indicated.
And for patients with none of the aforementioned characteristics or risks, ASC, office-based lab, or any hospital facility is acceptable.
The statement also provides guidance for operator experience. Those with less than 3 years’ experience, considered to have limited exposure to atherectomy devices and limited ST-segmented elevation MI (STEMI)/shock experience, should avoid doing PCIs in an ASC and performing atherectomy cases on their own, and have a colleague review case selection and assist in higher-risk cases. Experienced (3-10 years’ experience) and very experienced (more than 10 years’) should be able to perform in any setting and be competent with, if not highly experienced with, atherectomy and STEMI/shock.
Dr. Grines acknowledged the writing group didn’t want to set a specific operator volume requirement. “However, we recognize that lifetime operator experience is particularly important in more complex cases such as CTO, atherectomy, bifurcation stenoses, etc.,” she said. “In addition, performing these cases at a larger institution that has other operators that may assist in the event of a complication is very important. Specifically, we did not believe that recent fellow graduates with less than 3 years in practice or low-volume operators should attempt higher-risk cases in a no-SOS [surgeon-on-site] setting or perform cases in ASC or office-based labs where no colleagues are there to assist in case of a complication.”
In an interview, Gregory J. Dehmer, MD, professor of medicine at Virginia Tech University, Roanoke, reprised the theme of his accompanying editorial. “Things are evolving again, as Bob Dylan would say, ‘The Times They Are A-Changin’, so it’s very timely that the society in collaboration with other professional societies updated what are guidelines and rules of road if you’re going to do PCI in ASCs or office based laboratories,” said Dr. Dehmer, who chaired the writing committees of the 2007 and 2014 SCAI expert statements on PCI.
Having this statement is important for centers that don’t have on-site surgical backup, he said. “You couldn’t sustain a PCI operation at a rural hospital on just acute MIs alone. The key thing is that all of this built upon numerous studies both in the U.S. and abroad that showed the safety of doing elective cases – not only STEMIs, but elective PCI – at facilities without on-site surgery.”
CMS pushed the envelope when it decided to reimburse PCIs done in ASCs, Dr. Dehmer said. “That was not based on a lot of data. It was kind of a leap of faith. It’s logical that this should work, but in order for it to work and be safe for pats you have to follow the rules. That’s where SCAI stepped in at this point and said this is a whole new environment and we need to set some ground rules for physicians of who and who should not be having these procures in an office-based lab or an ambulatory surgery center.”

such as ambulatory surgery centers (ASCs) and office-based laboratories and which are best left to more traditional settings, such as hospitals with full cardiac support.
PCI has evolved quickly since SCAI issued its last update almost 9 years ago. The updated statement, published online in the Journal of the Society for Cardiovascular Angiography and Interventions, notes that the proportion of same-day PCI discharges has increased from 4.5% in 2009 to 28.6% in 2017.
The statement also notes that the Medicare facility fee for outpatient PCI in an ASC is about 40% less than the hospital fee: $6,111 versus $10,258 for the facility fee for 2022. The Centers for Medicare & Medicaid Services in 2020 extended coverage for PCIs in ASCs.
Rationale for update
Writing group chair Cindy Grines, MD, explained the rationale for updating the statement now. “The 2014 SCAI statement was very conservative, recommending only the simplest of cases be done without surgical backup,” Dr. Grines, chief scientific officer at Northside Hospital Cardiovascular Institute in Atlanta, said in an interview.
The statement drew on 12 global studies from 2015 to 2022 that evaluated more than 8 million PCIs at facilities with and without surgery on site. Dr. Grines noted those studies reported complication rates as low as 0.1% in PCI procedures in centers without surgical backup.
She also noted that the writing committee also received input that “by restricting the use of certain devices such as atherectomy, some patients who needed it as a bailout could be harmed.”
Another factor in prompting the statement update, Dr. Grines said: “Many hospitals have consolidated into heath systems, and these systems consolidated bypass surgery into one center. Therefore, centers with high volume, experienced operators, and excellent outcomes were now left with no surgery on site. It didn’t make sense to withdraw complex PCI from these centers who haven’t sent a patient for emergency bypass in several years.”
Statement guidance
The centerpiece of the update is an algorithm that covers the range of settings for PCI, from having a surgeon on site to ACS or office-based lab.
For example, indications for on-site surgical capability are PCI of the last remaining patent vessel or retrograde approach to epicardial chronic total occlusion (CTO), and when the patient is a candidate for surgery.
Indications for PCI in a hospital without on-site surgery but with percutaneous ventricular assist device or extracorporeal membrane oxygenation, calcium modification devices and high PCI volume are patients with decreased left ventricular ejection fraction, unprotected left main artery, CTO, or degenerated vein grafts.
For patients at high risk for transfusion, acute kidney injury or vascular complications, or who have high baseline respiratory risk, a hospital without on-site surgery but with respiratory care, blood bank, and vascular surgery services is indicated.
And for patients with none of the aforementioned characteristics or risks, ASC, office-based lab, or any hospital facility is acceptable.
The statement also provides guidance for operator experience. Those with less than 3 years’ experience, considered to have limited exposure to atherectomy devices and limited ST-segmented elevation MI (STEMI)/shock experience, should avoid doing PCIs in an ASC and performing atherectomy cases on their own, and have a colleague review case selection and assist in higher-risk cases. Experienced (3-10 years’ experience) and very experienced (more than 10 years’) should be able to perform in any setting and be competent with, if not highly experienced with, atherectomy and STEMI/shock.
Dr. Grines acknowledged the writing group didn’t want to set a specific operator volume requirement. “However, we recognize that lifetime operator experience is particularly important in more complex cases such as CTO, atherectomy, bifurcation stenoses, etc.,” she said. “In addition, performing these cases at a larger institution that has other operators that may assist in the event of a complication is very important. Specifically, we did not believe that recent fellow graduates with less than 3 years in practice or low-volume operators should attempt higher-risk cases in a no-SOS [surgeon-on-site] setting or perform cases in ASC or office-based labs where no colleagues are there to assist in case of a complication.”
In an interview, Gregory J. Dehmer, MD, professor of medicine at Virginia Tech University, Roanoke, reprised the theme of his accompanying editorial. “Things are evolving again, as Bob Dylan would say, ‘The Times They Are A-Changin’, so it’s very timely that the society in collaboration with other professional societies updated what are guidelines and rules of road if you’re going to do PCI in ASCs or office based laboratories,” said Dr. Dehmer, who chaired the writing committees of the 2007 and 2014 SCAI expert statements on PCI.

FROM THE JOURNAL OF SOCIETY FOR CARDIOVASCULAR ANGIOGRAPHY AND INTERVENTIONS
Three wild technologies about to change health care
When I was a child, I watched syndicated episodes of the original “Star Trek.” I was dazzled by the space travel, sure, but also the medical technology.
A handheld “tricorder” detected diseases, while an intramuscular injector (“hypospray”) could treat them. Sickbay “biobeds” came with real-time health monitors that looked futuristic at the time but seem primitive today.
Such visions inspired a lot of us kids to pursue science. Little did we know the real-life advances many of us would see in our lifetimes.
Artificial intelligence helping to spot disease, robots performing surgery, even video calls between doctor and patient – all these once sounded fantastical but now happen in clinical care.
Now, in the 23rd year of the 21st century, you might not believe wht we’ll be capable of next. Three especially wild examples are moving closer to clinical reality.
Human hibernation
Captain America, Han Solo, and “Star Trek” villain Khan – all were preserved at low temperatures and then revived, waking up alive and well months, decades, or centuries later. These are fictional examples, to be sure, but the science they’re rooted in is real.
one extreme case, a climber survived after almost 9 hours of efforts to revive him.)
Useful for a space traveler? Maybe not. But it’s potentially huge for someone with life-threatening injuries from a car accident or a gunshot wound.
That’s the thinking behind a breakthrough procedure that came after decades of research on pigs and dogs, now in a clinical trial. The idea: A person with massive blood loss whose heart has stopped is injected with an ice-cold fluid, cooling them from the inside, down to about 50° F.
Doctors already induce more modest hypothermia to protect the brain and other organs after cardiac arrest and during surgery on the aortic arch (the main artery carrying blood from the heart).
But this experimental procedure – called emergency preservation and resuscitation (EPR) – goes far beyond that, dramatically “decreasing the body’s need for oxygen and blood flow,” says Samuel Tisherman, MD, a trauma surgeon at the University of Maryland Medical Center and the trial’s lead researcher. This puts the patient in a state of suspended animation that “could buy time for surgeons to stop the bleeding and save more of these patients.”
The technique has been done on at least six patients, though none were reported to survive. The trial is expected to include 20 people by the time it wraps up in December, according to the listing on the U.S. clinical trials database. Though given the strict requirements for candidates (emergency trauma victims who are not likely to survive), one can’t exactly rely on a set schedule.
Still, the technology is promising. Someday we may even use it to keep patients in suspended animation for months or years, experts predict, helping astronauts through decades-long spaceflights, or stalling death in sick patients awaiting a cure.
Artificial womb
Another sci-fi classic: growing human babies outside the womb. Think the fetus fields from “The Matrix,” or the frozen embryos in “Alien: Covenant.”
In 1923, British biologist J.B.S. Haldane coined a term for that – ectogenesis. He predicted that 70% of pregnancies would take place, from fertilization to birth, in artificial wombs by 2074. That many seems unlikely, but the timeline is on track.
Developing an embryo outside the womb is already routine in in vitro fertilization. And technology enables preterm babies to survive through much of the second half of gestation. Normal human pregnancy is 40 weeks, and the youngest preterm baby ever to survive was 21 weeks and 1 day old, just a few days younger than a smattering of others who lived.
The biggest obstacle for babies younger than that is lung viability. Mechanical ventilation can damage the lungs and lead to a chronic (sometimes fatal) lung disease known as bronchopulmonary dysplasia. Avoiding this would mean figuring out a way to maintain fetal circulation – the intricate system that delivers oxygenated blood from the placenta to the fetus via the umbilical cord. Researchers at Children’s Hospital of Philadelphia have done this using a fetal lamb.
The key to their invention is a substitute placenta: an oxygenator connected to the lamb’s umbilical cord. Tubes inserted through the umbilical vein and arteries carry oxygenated blood from the “placenta” to the fetus, and deoxygenated blood back out. The lamb resides in an artificial, fluid-filled amniotic sac until its lungs and other organs are developed.
Fertility treatment could benefit, too. “An artificial womb may substitute in situations in which a gestational carrier – surrogate – is indicated,” says Paula Amato, MD, a professor of obstetrics and gynecology at Oregon Health and Science University, Portland. (Dr. Amato is not involved in the CHOP research.) For example: when the mother is missing a uterus or can’t carry a pregnancy safely.
No date is set for clinical trials yet. But according to the research, the main difference between human and lamb may come down to size. A lamb’s umbilical vessels are larger, so feeding in a tube is easier. With today’s advances in miniaturizing surgical methods, that seems like a challenge scientists can overcome.
Messenger RNA therapeutics
Back to “Star Trek.” The hypospray injector’s contents could cure just about any disease, even one newly discovered on a strange planet. That’s not unlike messenger RNA (mRNA) technology, a breakthrough that enabled scientists to quickly develop some of the first COVID-19 vaccines.
But vaccines are just the beginning of what this technology can do.
A whole field of immunotherapy is emerging that uses mRNA to deliver instructions to produce chimeric antigen receptor–modified immune cells (CAR-modified immune cells). These cells are engineered to target diseased cells and tissues, like cancer cells and harmful fibroblasts (scar tissue) that promote fibrosis in, for example, the heart and lungs.
The field is bursting with rodent research, and clinical trials have started for treating some advanced-stage malignancies.
Actual clinical use may be years away, but if all goes well, these medicines could help treat or even cure the core medical problems facing humanity. We’re talking cancer, heart disease, neurodegenerative disease – transforming one therapy into another by simply changing the mRNA’s “nucleotide sequence,” the blueprint containing instructions telling it what to do, and what disease to attack.
As this technology matures, we may start to feel as if we’re really on “Star Trek,” where Dr. Leonard “Bones” McCoy pulls out the same device to treat just about every disease or injury.

Drinking tea can keep your heart healthy as you age
according to the Heart Foundation and researchers from Edith Cowan University, Perth, Australia.
What to know
- Elderly women who drank black tea on a regular basis or consumed a high level of flavonoids in their diet were found to be far less likely to develop extensive AAC.
- AAC is calcification of the large artery that supplies oxygenated blood from the heart to the abdominal organs and lower limbs. It is associated with cardiovascular disorders, such as heart attack and stroke, as well as late-life dementia.
- Flavonoids are naturally occurring substances that regulate cellular activity. They are found in many common foods and beverages, such as black tea, green tea, apples, nuts, citrus fruit, berries, red wine, dark chocolate, and others.
- Study participants who had a higher intake of total flavonoids, flavan-3-ols, and flavonols were almost 40% less likely to have extensive AAC, while those who drank two to six cups of black tea per day had up to 42% less chance of experiencing extensive AAC.
- People who do not drink tea can still benefit by including foods rich in flavonoids in their diet, which protects against extensive calcification of the arteries.
This is a summary of the article, “Higher Habitual Dietary Flavonoid Intake Associates With Less Extensive Abdominal Aortic Calcification in a Cohort of Older Women,” published in Arteriosclerosis, Thrombosis, and Vascular Biology on Nov. 2, 2022.

- Study participants who had a higher intake of total flavonoids, flavan-3-ols, and flavonols were almost 40% less likely to have extensive AAC, while those who drank two to six cups of black tea per day had up to 42% less chance of experiencing extensive AAC.
- People who do not drink tea can still benefit by including foods rich in flavonoids in their diet, which protects against extensive calcification of the arteries.

Longer life after bariatric surgery, but suicide risk in young
Death from cardiovascular disease, cancer, and diabetes was 29%, 43%, and 72% lower, respectively, in the bariatric surgery patients versus nonsurgery peers, during a mean follow-up of 13 years (all P > .001).
However, the youngest group of bariatric surgery patients – who were 18-34 years old – had a fivefold increased risk of suicide during follow-up compared with their peers who did not undergo surgery (P = .001).
These findings are from a retrospective study in Utah that matched close to 22,000 patients with severe obesity who underwent Roux-en-Y gastric bypass, gastric banding, sleeve gastrectomy, or duodenal switch from 1982 to 2018 with an equal number of nonsurgery individuals.
The study, by Ted D. Adams, PhD, MPH, and colleagues, was published online in Obesity.
‘Impressive’ data, in men too, but psychological screening important
The overall improved survival and decreased deaths from diabetes, heart disease, and cancer over this long follow-up are “impressive,” Dr. Adams, of Intermountain Surgical Specialties/Digestive Health Clinical Program, Salt Lake City, said in an interview.
Previous studies have not shown a survival benefit from bariatric surgery versus no surgery in men, he said. However, “because we had a fair number of male patients and because of the length of follow-up, we did show that the improved mortality was not only evident for the female patients but also for the male patients,” Dr. Adams stressed.
Finding increased suicide rates among bariatric surgical patients who underwent surgery at a younger age (18-34 years) shows that “we need to try and determine who is at risk for suicide,” according to Dr. Adams.
Patients with severe obesity, especially younger ones, “may need more aggressive presurgical psychological screening and postsurgery follow-up,” wrote Dr. Adams and colleagues.
The findings may also “stimulate important research related to the discovery of physiologic and biomolecular mechanisms leading to nonsurgical treatment that results in weight loss and improved mortality similar to that achieved by bariatric surgery,” they suggested.
Close to 1 in 10 Americans has severe obesity
The prevalence of severe obesity (BMI ≥ 40 kg/m2) in the United States has increased from 4.7% during 1999-2000 to 9.2% during 2017-2018, based on National Health and Nutrition Examination Survey (NHANES) data, the researchers noted.
They previously published a study of long-term mortality in 7,925 patients who had gastric bypass surgery from 1984 to 2002 matched with patients with the same BMI who did not have bariatric surgery and were followed out to 2002.
The current study extends the follow-up through 2021, doubles the number of bypass patients, and includes three newer types of bariatric surgery.
The researchers matched 21,873 patients aged 18-80 who had Roux-en-Y gastric bypass, gastric banding, sleeve gastrectomy, or duodenal switch during 1982-2018 in Utah (from the Utah Population Database) with people of the same BMI category, age category (18-34, 35-44, 45-54, and 55-80 years), and sex (from Utah driver license data).
Most patients were women (79%) and most were White (94% and 85%). They had a mean age of 42 years and a mean BMI of 46 kg/m2.
Most patients had Roux-en-Y gastric bypass (69%), and the rest had sleeve gastrectomy (14%), gastric banding (12%), and duodenal switch (4.8%).
During follow-up, 13.5% of patients in the bariatric surgery group and 14.6% of people in the nonsurgery group died.
Overall, all-cause mortality was 16% lower in patients who had bariatric surgery versus matched nonsurgical participants; it was 14% lower in women and 21% lower in men (all P < .001).
All-cause mortality was significantly lower in patients who had bariatric surgery when they were 35-44, 45-54, and 55-80 years old compared with matched peers who did not have surgery.
However, the findings “should not imply patients necessarily postpone surgery until older age,” the researchers cautioned, “as postsurgical complications have been shown to increase with increasing age at surgery and surgical postponement may result in worsened clinical status related to certain conditions such as orthopedic joint health.”
The researchers found significantly improved all-cause mortality following either type of surgery (gastric bypass, gastric banding, and sleeve gastrectomy) compared with no surgery.
Along with fewer deaths from cardiovascular disease, cancer, and diabetes, deaths from lung disease were 39% lower in the surgery group than in the nonsurgery group.
However, in the youngest group (age 18-34), deaths from cirrhosis of the liver were significantly higher in the patients who had bariatric surgery, and rates of suicide were significantly greater for both females and males, compared with similar people who did not undergo surgery.
The study was supported by grants from Ethicon Endo-Surgery (Johnson & Johnson); the National Institute of Diabetes and Digestive and Kidney Diseases, a division of the National Institutes of Health; U.S. Public Health Service; and Intermountain Research and Medical Foundation of Intermountain Healthcare. Dr. Adams disclosed ties to Ethicon Endo-Surgery and Intermountain Healthcare. A coauthor reported ties with Biomedical Research Program at Weill Cornell Medicine in Qatar, a program funded by the Qatar Foundation. The other authors have reported no relevant financial relationships.

Acute cardiac events common during COVID hospitalization
particularly among those with underlying heart disease, and are associated with more severe disease outcomes, a new study suggests.
“We expected to see acute cardiac events occurring among adults hospitalized with COVID-19 but were surprised by how frequently they occurred,” Rebecca C. Woodruff, PhD, MPH, of the U.S. Centers for Disease Control and Prevention, Atlanta, told this news organization.
Overall, she said, “about 1 in 10 adults experienced an acute cardiac event – including heart attacks and acute heart failure – while hospitalized with COVID-19, and this included people with no preexisting heart disease.”
However, she added, “about a quarter of those with underlying heart disease had an acute cardiac event. These patients tended to experience more severe disease outcomes relative to patients hospitalized with COVID-19 who did not experience an acute cardiac event.”
The findings might be relevant to hospitalizations for other viral diseases, “though we can’t say for sure,” she noted. “This study was modeled off a previous study conducted before the COVID-19 pandemic among adults hospitalized with influenza. About 11.7% of [those] adults experienced an acute cardiac event, which was a similar percentage as what we found among patients hospitalized with COVID-19.”
The study was published online in the Journal of the American College of Cardiology.
Underlying cardiac disease key
Dr. Woodruff and colleagues analyzed medical records on a probability sample of 8,460 adults hospitalized with SARS-CoV-2 infection identified from 99 U.S. counties in 14 U.S. states (about 10% of the United States population) from January to November 2021.
Among participants, 11.4% had an acute cardiac event during their hospitalization. The median age was 69 years; 56.5% were men; 48.7%, non-Hispanic White; 33.6%, non-Hispanic Black; 7.4%, Hispanic; and 7.1%, non-Hispanic Asian or Pacific Islander.
As indicated, the prevalence was higher among those with underlying cardiac disease (23.4%), compared with those without (6.2%).
Acute ischemic heart disease (5.5%) and acute heart failure (5.4%) were the most prevalent events; 0.3% of participants had acute myocarditis or pericarditis.
Risk factors varied, depending on underlying cardiac disease status. Those who experienced one or more acute cardiac events had a greater risk for intensive care unit admission (adjusted risk ratio,1.9) and in-hospital death (aRR, 1.7) versus those who did not.
In multivariable analyses, the risk of experiencing acute heart failure was significantly greater among men (aRR, 1.5) and among those with a history of congestive heart failure (aRR, 13.5), atrial fibrillation (aRR, 1.6) or hypertension (aRR,1.3).
Among patients who experienced one or more acute cardiac events, 39.2% required an intensive care unit stay for a median of 5 days. Approximately 22.4% required invasive mechanical ventilation or extracorporeal membrane oxygenation, and 21.1% died while hospitalized.
“Persons at greater risk for experiencing acute cardiac events during COVID-19–associated hospitalizations might benefit from more intensive clinical evaluation and monitoring during hospitalization,” the authors conclude.
The team currently is taking a closer look at acute myocarditis among patients hospitalized with COVID-19, Dr. Woodruff said. Preliminary results were presented at the 2022 annual scientific sessions of the American Heart Association and a paper is forthcoming.
Contemporary data needed
James A. de Lemos, MD, co-chair of the American Heart Association’s COVID-19 CVD Registry Steering Committee and professor of medicine at the University of Texas Southwestern Medical Center, Dallas, said the findings mirror his team’s clinical experience in 2020 and 2021 and echo what was seen in the AHA COVID registry: that is, a 0.3% rate of myocarditis.
“The major caveat is that [the findings] may not be generalizable to contemporary COVID infection, both due to changing viral variants and higher levels of immunity in the population,” he said.
“Rates of COVID hospitalization are markedly lower with the current dominant variants, and we would expect the cardiac risk to be lower as well. I would like to see more contemporary data with current variants, particularly focused on higher risk patients with cardiovascular disease,” Dr. de Lemos added.
In a related editorial, George A. Mensa, MD, of the National Heart, Lung, and Blood Institute in Bethesda, Md., and colleagues suggest that the broader impact of the COVID-19 pandemic on human health remains “incompletely examined.”
“The impact of COVID-19 on cardiovascular mortality, in particular, appears to have varied widely, with no large increases seen in a number of the most developed countries but marked increases in hypertensive heart disease mortality seen in the United States in 2021,” they conclude. “The potential contribution of COVID-19 to these deaths, either directly or indirectly, remains to be determined.”
No commercial funding or relevant financial relationships were reported.

Universal testing for Lp(a): What are we waiting for?
atherosclerotic cardiovascular disease (ASCVD), but whether an elevated blood level was a biomarker or a causal factor proved difficult to determine. Studies of inheritance patterns confirmed that blood levels were primarily genetically determined and largely resistant to lifestyle and pharmacologic intervention. It seemed senseless to test for something that was deemed “unmodifiable,” so untreatable. That label stuck for decades.
It soon became clear that Lp(a) was associated withFortunately, a resurgent interest in molecular pathophysiology this past decade has clarified Lp(a)’s unique contribution to atherothrombotic disease and calcific aortic stenosis. While there remains much to be learned about this complex, highly atherogenic molecule and its role in cardiac disease, it seems shortsighted not to take the simple step of identifying who carries this risk. Why are we not testing everyone for an extremely common and potent risk factor for the most lethal disease on the planet?
Epidemiologic studies project a stunning number of people in the United States to be at increased risk for Lp(a)-mediated coronary and cerebrovascular events. Because the LPA gene which codes for the apo(a) component of the Lp(a) molecule is fully expressed at age 2, this is a truly lifelong risk factor for a projected 64 million individuals with blood levels (> 60 mg/dL) high enough to double their risk for ASCVD. Because risk increases linearly, this includes 16 million, like me, with levels > 116 mg/dL, who are at four times the risk for ASCVD as those with normal levels (< 30 mg/dL).
Because Lp(a) level remains relatively constant throughout life, a single blood test would help stratify the risk it confers on millions of people who, under current U.S. guidelines, would never be tested. Until Lp(a) is integrated into its algorithms, the commonly used ASCVD Risk Calculator will substantially underestimate risk in 20% of the population.
A potential barrier to universal testing is that the ideal method to measure Lp(a) has yet to be determined. Lp(a) comprises an apoB particle bonded to an apo(a) particle. Apo(a) is complex and has a number of isoforms that can result in large heterogeneity in apo(a) size between, as well as within, individuals. This contributes to controversy about the ideal assay and whether Lp(a) levels should be expressed as mass (mg/dL) or number of particles (nmols/L). This should not, however, deter universal testing.
One-time cost, lifetime benefit?
Absent universal testing, it’s impossible to estimate the economic toll that Lp(a) exacts, but it’s surely an extraordinary number, particularly because the highest-risk individuals are prone to recurrent, nonfatal vascular events. The substantial price tag for my personal decade of Lp(a)-induced vascular havoc included four percutaneous coronary interventions with rapid stent restenosis, an eventual bypass surgery, and an aborted left hemispheric stroke, requiring an urgent carotid endarterectomy.
As a frame of reference, U.S. expenditures related to ASCVD are estimated to be $351 billion annually. If everyone in the United States over the age of 18 were tested for Lp(a) at a cost of $100 per person, this would be a $21 billion expenditure. This nonrecurring expense would identify the 20% – or almost 42 million individuals – at high risk for ASCVD, a number of whom would have already had vascular events. This one-time cost would be a foundational step in securing year-after-year savings from enhanced ASCVD prevention and reduction in recurrent vascular events.
Such savings would be significantly enhanced if and when targeted, effective Lp(a) treatments become available, but it seems shortsighted to make this the linchpin for universal testing. It’s noteworthy that Canadian and European guidelines already endorse one-time testing for all.
The confirmation of Lp(a)’s causal role in ASCVD remains underappreciated by medical providers across all specialties. Much of the elegant Lp(a)-related science of the past decade has yet to translate to the clinical world. What better way to rectify this than by identifying those with high Lp(a)? Since the advent of the statin era, “good” and “bad” cholesterol values are common conversational fare, in part because virtually every adult has had not one, but many lipid panels. Universal Lp(a) testing would spotlight this pervasive and important risk factor that was referred to as the “horrible” cholesterol in a recent review.
U.S. guidelines need updating
To foster this, U.S. guidelines, which influence every aspect of care, including testing, prevention, treatment, reimbursement, and medical legal issues, need to be simplified. The discussion of Lp(a) testing in the 2018 U.S. guidelines on cholesterol management is already obsolete. The contingencies on when testing is “reasonable” or “may be reasonable” are dated and cumbersome. In contrast, a recommendation to test everyone once, perhaps in adolescence, would be a useful, forward-looking strategy.
To date, trials of an antisense oligonucleotide and a small interfering RNA molecule targeting hepatic LPA messenger RNA have confirmed that plasma Lp(a) levels can be significantly and safely lowered. If the ongoing Lp(a) HORIZON and OCEAN(a) phase 3 trials have positive outcomes in patients with known ASCVD, this would spawn a host of clinical trials to explore the possibilities of these therapies in primary prevention as well. These will require tens of thousands of enrollees, and universal testing would expand the pool of potential participants.
The majority of at-risk individuals identified through universal testing would be candidates for primary prevention. This large, currently unidentified cohort should have all coexisting risk factors assessed and managed; lowering elevated LDL cholesterol early and aggressively is paramount. Recent data from the United Kingdom suggest that attainment of specific LDL cholesterol levels may offset the risk for vascular events in those with high Lp(a) levels.
Of note, this was the advice given to the small fraction of high-risk individuals like me, who had their Lp(a) level tested long before its ominous implications were understood. This recommendation was informed mostly by common sense. For any number of reasons, the same might be said for universal testing.
Dr. Leahy, a retired cardiologist in San Diego, has an abiding professional and personal interest in Lp(a), which has been responsible for a number of cardiovascular events in his own life over the past 2 decades. He was a participant in the phase 2 clinical trial of the Lp(a)-lowering antisense oligonucleotide being studied in the Lp(a) HORIZON trial, funded by Novartis, and is currently undergoing apheresis treatment.

atherosclerotic cardiovascular disease (ASCVD), but whether an elevated blood level was a biomarker or a causal factor proved difficult to determine. Studies of inheritance patterns confirmed that blood levels were primarily genetically determined and largely resistant to lifestyle and pharmacologic intervention. It seemed senseless to test for something that was deemed “unmodifiable,” so untreatable. That label stuck for decades.
It soon became clear that Lp(a) was associated withFortunately, a resurgent interest in molecular pathophysiology this past decade has clarified Lp(a)’s unique contribution to atherothrombotic disease and calcific aortic stenosis. While there remains much to be learned about this complex, highly atherogenic molecule and its role in cardiac disease, it seems shortsighted not to take the simple step of identifying who carries this risk. Why are we not testing everyone for an extremely common and potent risk factor for the most lethal disease on the planet?
Epidemiologic studies project a stunning number of people in the United States to be at increased risk for Lp(a)-mediated coronary and cerebrovascular events. Because the LPA gene which codes for the apo(a) component of the Lp(a) molecule is fully expressed at age 2, this is a truly lifelong risk factor for a projected 64 million individuals with blood levels (> 60 mg/dL) high enough to double their risk for ASCVD. Because risk increases linearly, this includes 16 million, like me, with levels > 116 mg/dL, who are at four times the risk for ASCVD as those with normal levels (< 30 mg/dL).
