The confluence of atrial septal aneurysm and patent foramen ovale in noncoronary sinus of Valsalva has not been previously documented in the literature.

A 53 year-old white male with a past medical history of hypertension, hyperlipidemia, and former tobacco use was referred to the Dayton VAMC in Ohio for symptoms that included shortness of breath and a recent abnormal stress test. The patient reported no history of known coronary artery disease (CAD), congestive heart failure, or other cardiovascular diseases. The patient also reported no recent fever, bacterial blood infection, syphilis infection, recreational drug use, or chest trauma.

A physical examination was remarkable for grade 3/6 continuous murmur at the 5th interspace to the left of the sternum and a loud “pistol shot” sound heard over the femoral artery. The patient had jugular venous distension and 2+ leg edema bilaterally. His vital signs were normal, and laboratory blood tests showed normal hemoglobin level and kidney function.

An electrocardiogram showed nonspecific ST segment changes and a transthoracic echocardiogram (TTE) revealed a high-velocity jet in the right atrium (RA) above the tricuspid valve concerning for sinus of Valsalva aneurysm (SVA).

A transesophageal echocardiogram (TEE) showed a “windsock” appearance of the noncoronary SVA with possible rupture into the RA (Figure 1) and atrial septal aneurysm (ASA) with more than 2-cm displacement beyond the plane of the atrial septum and a 2-mm patent foramen ovale (PFO) (Figure 2).

 

Right heart catheterization revealed elevated RA pressures with positive shunt study showing oxygen saturation step-up in the RA (Figure 3). Left heart hemodynamic measurement from an aortic approach to the distal part of the noncoronary cusp SVA revealed an RA pressure-tracing pattern consistent with rupture of the noncoronary SVA into the RA (Figure 4).

Coronary angiography revealed single vessel CAD involving the proximal right coronary artery.

The primary diagnosis was of acute heart failure secondary to ruptured aneurysm of the noncoronary SVA into RA. The patient also received a secondary diagnosis of atrial septal aneurysm and PFO.

Treatment & Outcome

The patient was treated with aggressive diuresis and responded well to therapy. Considering the high mortality rate associated with a ruptured SVA, the patient was referred to a tertiary care center for surgical evaluation. He underwent repair of aorto-right atrial communication with a Cormatrix patch (Roswell, GA) from the aortic side and with primary closure from the right atrial side with resection of the windsock tract; coronary artery bypass graft x1 with right internal mammary artery to the right coronary artery; closure of the PFO with the Cormatrix patch.

The postoperative TEE confirmed preserved LV and RV function, no shunts, no aortic or tricuspid insufficiency. Biopsy of the tissue resected showed intimal fibroplasia. A TTE completed 1 year after surgery showed normal valvular function and without any structural abnormalities. The patient had improvement in symptoms and an uneventful year after surgical intervention followed by 24 session of cardiac rehabilitation.

 

 

Discussion

Sinus of Valsalva aneurysm is a dilation of the aortic wall between the aortic valve and the sinotubular junction that is caused by the lack of continuity between the middle layer of the aortic wall and the aortic valve.1 Cases of SVA are rare cardiac anomalies with prevalence of 1% in patients undergoing open-heart surgery.2 Between 65% and 85% of SVA cases originate from the right coronary sinus, 10% to 20% from the noncoronary sinus, and < 5% from the left coronary sinus.3

Sinus of Valsalva aneurysm is usually congenital, although cases associated with syphilis, bacterial endocarditis, trauma, Behçet disease, and aortic dissection have been reported. Structural defects associated with congenital SVAs include ventricular septal defect, bicuspid aortic valve, and aortic regurgitation. It is less commonly associated with pulmonary stenosis, coarctation of the aorta, patent ductus arteriosus, tricuspid regurgitation, and atrial septal defects.

The most common complication of the SVA is rupture into another cardiac chamber, frequently the right ventricle (60%) or RA (29%) and less frequently into left atrium (6%), left ventricle (4%), or pericardium (1%).1 Patients with ruptured SVA mainly develop dyspnea and chest pain, but cough, fatigue, peripheral edema, and continuous murmur have been reported.1

Atrial septal aneurysm is an uncommon finding in adults, with an incidence of 2.2 % in the general population, and it is often associated with atrial septal defect and PFO.1,4 Although ASA formation can be secondary to interatrial differences in pressures, it can be a primary malformation involving the region of the fossa ovalis or the entire atrial septum.4 Atrial septal aneurysm may be an isolated anomaly, but often is found in association with other structural cardiac anomalies, including SVA and PFO.4,5

Conclusion

Although coexistence of SVA and ASA has been reported previously, the case reported here, a ruptured noncoronary SVA that was associated with a large ASA and a PFO, has not been previously documented in the English literature. This patient’s anomalies are most likely congenital in origin. Progressive dyspnea and chest pain in the presence of a continuous loud murmur should raise the suspicion of ruptured sinus of Valsalva. Although no significant aortic regurgitation was noted on echocardiography, the pistol shot sound heard over the femoral artery was believed to be due to the rapid diastolic runoff into the RA through the ruptured SVA.

The significant increase in the RA pressure made the ASA and PFO more prominent. A TEE, left and right heart catheterizations with shunt study are vital for the diagnosis of SVA. If left untreated, SVA has an ominous prognosis. Surgical repair of ruptured SVA has an accepted risk and good prognosis with 10-year survival rate of 90%, whereas the mean survival of untreated ruptured SVA is about 4 years.6,7 Hence, the patient in this study was referred to a tertiary care center for surgical intervention.

PRECISE-DAPT Score Predicts GI Bleeding Risk Among Post-PCI Patients

Article Type

Fri, 11/15/2024 - 15:45

— Gastrointestinal (GI) bleeding after percutaneous coronary intervention (PCI) among patients on dual antiplatelet therapy (DAPT) remains risky in terms of morbidity and mortality, but the Predicting Bleeding Complications in Patients Undergoing Stent Implantation and Subsequent Dual Antiplatelet Therapy (PRECISE-DAPT) score could help predict that risk, according to a study presented at the American College of Gastroenterology (ACG) 2024 Annual Scientific Meeting.

In a predominantly Hispanic population in Texas, 2.5% of post-PCI patients on DAPT had GI bleeding in the first year. The PRECISE-DAPT score helped to predict GI bleeding among high-risk and moderate-risk patients.

“Our study established that the PRECISE-DAPT score possesses a moderate predictive accuracy not only for overall bleeding risk but also specifically for gastrointestinal bleeding,” said lead author Jesus Guzman, MD, a gastroenterology fellow at the Texas Tech University Health Sciences Center El Paso.

Current guidelines from the American College of Cardiology and American Heart Association recommend DAPT for 6-12 months post-PCI, with consideration for shorter durations in patients with lower ischemic risks but higher bleeding risks.

“Interestingly, some of these patients were on DAPT for more than 2 years, which goes beyond the guidelines,” he said. “In this patient population, this has to do with them being lost to follow-up and getting reestablished, and they kept refilling their prescriptions.”

Guzman and colleagues conducted a retrospective cohort study of patients receiving DAPT after PCI from 2014 to 2021. They looked for GI bleeding rates at 1 year and across the duration of the study period, as well as endoscopic indications, findings, concurrent antiplatelet therapy, and the primary cause of bleeding.

In addition, the research team evaluated the predictive value of the PRECISE-DAPT score, which categorizes patients based on low risk (≤ 17), moderate risk (18-24), and high risk (≥ 25) for bleeding. The score aims to optimize the balance between bleeding and ischemic risks, Guzman said, by incorporating five factors: Age, creatinine clearance, hemoglobin, white blood cell count, and history of spontaneous bleeding.

Among 1067 patients, 563 (57.9%) received clopidogrel and 409 (42%) received ticagrelor. The overall cohort was 66.6% men, 77.1% Hispanic, and had a mean age of 62 years.

The GI bleeding rate was 2.5% at 1-year post-PCI among 27 patients and 3.7% for the study duration among 39 patients, with a median follow-up of 2.2 years.

Among the 39 GI bleeds, 41% were lower GI bleeds, 28% were upper GI bleeds, 15% were small bowel bleeds, and 15% were undetermined. The most frequent etiology was colon cancer, accounting for 18% of bleeds, followed by 15% for gastric ulcers, 10% for diverticular bleeds, and 10% for hemorrhoidal bleeds.

In general, analyses indicated no significant differences in GI bleeding between patients on clopidogrel (21.2%) and those on ticagrelor (19.2%).

However, the odds of GI bleeding were significantly higher in patients with high-risk PRECISE-DAPT scores (odds ratio [OR], 2.5) and moderate-risk scores (OR, 2.8) than in those with low-risk scores. The majority of patients without GI bleeding had scores < 17, whereas the majority of patients with GI bleeding had scores > 24. An optimal threshold for the PRECISE-DAPT score was identified as ≥ 19.

“When patients on DAPT present with GI bleeding, it can be a clinical conundrum for gastroenterologists and cardiologists, especially when it can be a life-or-death event, and stopping DAPT can increase risk of thrombosis,” said Jeff Taclob, MD, a hepatology fellow at The University of Tennessee Health Science Center in Memphis. Taclob, who wasn’t involved with the study, attended the conference session.

“In this population in El Paso, in particular, many patients don’t have adequate healthcare, may be lost to follow-up, and get their prescriptions filled elsewhere, such as Juárez, Mexico,” he said. “Then they come in with this life-threatening bleed, so we need to focus more on their risks.”

Paying attention to specific patient populations, cultures, and values remains important for patient communication and clinical decision-making, Taclob noted.

“In this population of older men, there’s often a macho persona where they don’t want to seek help,” he said. “DAPT criteria could differ in other populations, but here, the PRECISE-DAPT score appeared to help.”

The study was awarded the ACG Outstanding Research Award in the GI Bleeding Category (Trainee). Guzman and Taclob reported no relevant disclosures.

An optimal threshold for the PRECISE-DAPT score was identified as ≥ 19.

“When patients on DAPT present with GI bleeding, it can be a clinical conundrum for gastroenterologists and cardiologists, especially when it can be a life-or-death event, and stopping DAPT can increase risk of thrombosis,” said Jeff Taclob, MD, a hepatology fellow at The University of Tennessee Health Science Center in Memphis. Taclob, who wasn’t involved with the study, attended the conference session.

“In this population in El Paso, in particular, many patients don’t have adequate healthcare, may be lost to follow-up, and get their prescriptions filled elsewhere, such as Juárez, Mexico,” he said. “Then they come in with this life-threatening bleed, so we need to focus more on their risks.”

Paying attention to specific patient populations, cultures, and values remains important for patient communication and clinical decision-making, Taclob noted.

“In this population of older men, there’s often a macho persona where they don’t want to seek help,” he said. “DAPT criteria could differ in other populations, but here, the PRECISE-DAPT score appeared to help.”

The study was awarded the ACG Outstanding Research Award in the GI Bleeding Category (Trainee). Guzman and Taclob reported no relevant disclosures.

— Gastrointestinal (GI) bleeding after percutaneous coronary intervention (PCI) among patients on dual antiplatelet therapy (DAPT) remains risky in terms of morbidity and mortality, but the Predicting Bleeding Complications in Patients Undergoing Stent Implantation and Subsequent Dual Antiplatelet Therapy (PRECISE-DAPT) score could help predict that risk, according to a study presented at the American College of Gastroenterology (ACG) 2024 Annual Scientific Meeting.

In a predominantly Hispanic population in Texas, 2.5% of post-PCI patients on DAPT had GI bleeding in the first year. The PRECISE-DAPT score helped to predict GI bleeding among high-risk and moderate-risk patients.

“Our study established that the PRECISE-DAPT score possesses a moderate predictive accuracy not only for overall bleeding risk but also specifically for gastrointestinal bleeding,” said lead author Jesus Guzman, MD, a gastroenterology fellow at the Texas Tech University Health Sciences Center El Paso.

Current guidelines from the American College of Cardiology and American Heart Association recommend DAPT for 6-12 months post-PCI, with consideration for shorter durations in patients with lower ischemic risks but higher bleeding risks.

“Interestingly, some of these patients were on DAPT for more than 2 years, which goes beyond the guidelines,” he said. “In this patient population, this has to do with them being lost to follow-up and getting reestablished, and they kept refilling their prescriptions.”

Guzman and colleagues conducted a retrospective cohort study of patients receiving DAPT after PCI from 2014 to 2021. They looked for GI bleeding rates at 1 year and across the duration of the study period, as well as endoscopic indications, findings, concurrent antiplatelet therapy, and the primary cause of bleeding.

In addition, the research team evaluated the predictive value of the PRECISE-DAPT score, which categorizes patients based on low risk (≤ 17), moderate risk (18-24), and high risk (≥ 25) for bleeding. The score aims to optimize the balance between bleeding and ischemic risks, Guzman said, by incorporating five factors: Age, creatinine clearance, hemoglobin, white blood cell count, and history of spontaneous bleeding.

Among 1067 patients, 563 (57.9%) received clopidogrel and 409 (42%) received ticagrelor. The overall cohort was 66.6% men, 77.1% Hispanic, and had a mean age of 62 years.

The GI bleeding rate was 2.5% at 1-year post-PCI among 27 patients and 3.7% for the study duration among 39 patients, with a median follow-up of 2.2 years.

Among the 39 GI bleeds, 41% were lower GI bleeds, 28% were upper GI bleeds, 15% were small bowel bleeds, and 15% were undetermined. The most frequent etiology was colon cancer, accounting for 18% of bleeds, followed by 15% for gastric ulcers, 10% for diverticular bleeds, and 10% for hemorrhoidal bleeds.

In general, analyses indicated no significant differences in GI bleeding between patients on clopidogrel (21.2%) and those on ticagrelor (19.2%).

However, the odds of GI bleeding were significantly higher in patients with high-risk PRECISE-DAPT scores (odds ratio [OR], 2.5) and moderate-risk scores (OR, 2.8) than in those with low-risk scores. The majority of patients without GI bleeding had scores < 17, whereas the majority of patients with GI bleeding had scores > 24. An optimal threshold for the PRECISE-DAPT score was identified as ≥ 19.

“When patients on DAPT present with GI bleeding, it can be a clinical conundrum for gastroenterologists and cardiologists, especially when it can be a life-or-death event, and stopping DAPT can increase risk of thrombosis,” said Jeff Taclob, MD, a hepatology fellow at The University of Tennessee Health Science Center in Memphis.

‘No Hint of Benefit’ in Large Colchicine Trial

Article Type
Changed
Fri, 11/15/2024 - 13:46

Colchicine does not protect against major cardiovascular adverse events after an acute myocardial infarction, according to a multinational placebo-controlled trial of more than 7000 patients.

The CLEAR SYNERGY (OASIS 9) study, called “the largest trial ever of colchicine in acute MI,” showed no hint of benefit in an adverse event curve for colchicine relative to placebo over 5 years, which suggests that the role of this drug after myocardial infarction (MI) “is uncertain,” Sanjit Jolly, MD, an interventional cardiologist at Hamilton Health Sciences and a professor of medicine at McMaster University in Hamilton, Ontario, Canada, reported at Transcatheter Cardiovascular Therapeutics (TCT) 2024.

For the primary composite outcome — cardiovascular death, MI, stroke, and ischemia-driven revascularization — the event curves in the colchicine and placebo groups remained essentially superimposed over 5 years of follow-up, with only a slight separation after 4 years. The hazard ratio for the primary endpoint showed a 1% difference in favor of colchicine (hazard ratio [HR], 0.99; P = .93).

There were no meaningful differences in any of the individual endpoint components; all 95% CIs straddled the line of unity. Rates of cardiovascular death (3.3% vs 3.2%) and stroke (1.4% vs 1.2%) were numerically higher in the colchicine group than in the placebo group. Rates of MI (2.9% vs 3.1%) and ischemia-driven revascularization (4.6% vs 4.7%) were numerically lower in the colchicine group.

 

No Difference

No adverse outcomes, including all-cause death (4.6% vs 5.1%), approached significance, with the exception of noncardiovascular death (13.0% vs 1.9%). For this outcome, the 95% CI stopped just short of the line of unity (HR, 0.68; 95% CI, 0.46-0.99).

Rates of adverse events (31.9% vs 31.7%; P = .86), serious adverse events (6.7% vs 7.4%; P = .22), and serious infections (2.5% vs 2.9%; P = .85) were similar in the colchicine and placebo groups, but diarrhea, a known side effect of colchicine, was higher in the colchicine group (10.2% vs 6.6%; P < .001).

Given these results, a panelist questioned the use of the word “uncertain” to describe the findings during the late-breaker session in which these results were presented.

“I think you are selling yourself short,” said J. Dawn Abbott, MD, director of the Interventional Cardiology Fellowship Training Program at the Lifespan Cardiovascular Institute, Brown University in Providence, Rhode Island. Based on the size and conduct of this trial, she called the results “definitive” and suggested that the guidelines should be adjusted.

 

The OASIS 9 Trial

In OASIS 9, 3528 patients were randomized to colchicine, and 3534 were randomized to placebo. A second randomization in both groups was to spironolactone or placebo; these results will be presented at the upcoming American Heart Association (AHA) 2024 meeting. Both analyses will be published in The New England Journal of Medicine at that time, Jolly reported.

The study involved 104 sites in Australia, Egypt, Europe, Nepal, and North America. Follow-up in both groups exceeded 99%. Most patients had an ST-elevation MI (STEMI), but about 5% of those enrolled had a non-STEMI. Less than 10% of patients had experienced a previous MI.

Less than 5% of patients were discharged on sodium-glucose cotransporter 2 therapy, and more than 95% were discharged on aspirin and a statin. Nearly 80% were discharged on an angiotensin-converting enzyme inhibitor, and most patients received an anticoagulant. More than 95% of patients were implanted with a drug-eluting stent.

At month 3, C-reactive protein levels were significantly lower in the colchicine group than in the placebo group. C-reactive protein is a biomarker for the anti-inflammatory effect that is considered to be colchicine’s primary mechanism of action. An anti-inflammatory effect has been cited as the probable explanation for the positive results shown in the COLCOT and LODOCO2 trials, published in 2019 and 2020, respectively.

In COLCOT, which randomized 4745 patients who experienced an acute MI in the previous 30 days, colchicine was associated with a 23% reduction in a composite major cardiovascular adverse events endpoint relative to placebo (HR, 0.77; P = .02). In LODOCO2, which randomized 5522 patients with chronic coronary disease, colchicine was associated with a 31% reduction in an adverse event composite endpoint (HR, 0.68; P < .0001).

However, two more recent trials — CONVINCE and CHANCE-3 — showed no difference between colchicine and placebo for the endpoint of recurrent stroke at 90 days. CONVINCE, with approximately 3000 patients, was relatively small, whereas CHANCE-3 randomized more than 8000 patients and showed no effect on the risk for stroke (HR, 0.98; 95% CI, 0.83-1.16).

 

New Data Challenge Guidelines

Of these trials, COLCOT was the most similar to OASIS 9, according to Jolly. Among the differences, OASIS 9 was initiated earlier and was larger than the other trials, so it had more power to address the study question.

Given the absence of benefit, Jolly indicated that OASIS 9 might disrupt both the joint American College of Cardiology and AHA guidelines, which gave colchicine a class 2b recommendation in 2023, and the European Society of Cardiology guidelines, which gave colchicine a 2a recommendation.

“This is a big deal for me,” said Ajay J. Kirtane, director of the Interventional Cardiovascular Care program at Columbia University in New York City. As someone who is now using colchicine routinely, these data have changed his opinion.

The previous data supporting the use of colchicine “were just so-so,” he explained. “Now I have a good rationale” for foregoing the routine use of this therapy.

Jolly said that he had put his own father on colchicine after an acute MI on the basis of the guidelines, but immediately took him off this therapy when the data from OASIS 9 were unblinded.

“The only signal from this trial was an increased risk of diarrhea,” Jolly said. The results, at the very least, suggest that colchicine “is not for everyone” after an acute MI, although he emphasized that these results do not rule out the potential for benefit from anti-inflammatory therapy. Ongoing trials, including one targeting interleukin 6, a cytokine associated with inflammation, remain of interest, he added.

Goodbye CHADSVASc: Sex Complicates Stroke Risk Scoring in AF

Article Type
Changed
Thu, 11/14/2024 - 22:37

The European Society of Cardiology (ESC) caused a stir when they recommended in their latest atrial fibrillation (AF) management guideline that gender no longer be included in the decision to initiate oral anticoagulation therapy.

The move aims to level the playing field between men and women and follows a more nuanced understanding of stroke risk in patients with AF, said experts. It also acknowledges the lack of evidence in people receiving cross-sex hormone therapy.

In any case, the guidelines, developed in collaboration with the European Association for Cardio-Thoracic Surgery and published by the European Heart Journal on August 30, simply follow 2023’s US recommendations, they added.

 

One Size Does Not Fit All

So, what to the ESC guidelines actually say?

They underline that, if left untreated, the risk for ischemic stroke is increased fivefold in patients with AF, and the “default approach should therefore be to provide oral anticoagulation to all eligible AF patients, except those at low risk for incident stroke or thromboembolism.”

However, the authors note that there is a lack of strong evidence on how to apply the current risk scores to help inform that decision in real-world patients.

Dipak Kotecha, MBChB, PhD, Professor of Cardiology at the University of Birmingham and University Hospitals Birmingham NHS Foundation Trust, Birmingham, England, and senior author of the ESC guidelines, said in an interview that “the available scores have a relatively poor ability to accurately predict which patients will have a stroke or thromboembolic event.”

Instead, he said “a much better approach is for healthcare professionals to look at each patient’s individual risk factors, using the risk scores to identify those patients that might not benefit from oral anticoagulant therapy.”

For these guidelines, the authors therefore wanted to “move away from a one-size-fits-all” approach, Kotecha said, and instead ensure that more patients can benefit from the new range of direct oral anticoagulants (DOACs) that are easier to take and with much lower chance of side effects or major bleeding.

To achieve this, they separated their clinical recommendations from any particular risk score, and instead focused on the practicalities of implementation.

 

Risk Modifier Vs Risk Factor

To explain their decision the authors highlight that “the most popular risk score” is the CHA2DS2–VASc, which gives a point for female sex, alongside factors such as congestive heart failure, hypertension, and diabetes mellitus, and a sliding scale of points for increasing age.

Kotecha pointed out the score was developed before the DOACs were available and may not account for how risk factors have changed in recent decades.

The result is that CHA2DS2–VASc gives the same number of points to an individual with heart failure or prior transient ischemic attack as to a woman aged less than 65 years, “but the magnitude of increased risk is not the same,” Usha Beth Tedrow, MD, Associate Professor of Medicine, Brigham and Women’s Hospital, Boston, Massachusetts, said in an interview.

As far back as 2018, it was known that “female sex is a risk modifier, rather than a risk factor for stroke in atrial fibrillation,” noted Jose Joglar, MD, lead author of the 2023 ACC/AHA/ACCP/HRS Guideline for the Diagnosis and Management of Atrial Fibrillation said in an interview.

Danish national registry study involving 239,671 AF patients treated between 1997 and 2015, nearly half of whom were women, showed that, at a CHA2DS2–VASc score of 0, the “risk of stroke between men and women is absolutely the same,” he said.

“It is not until after a CHA2DS2–VASc score of 2 that the curves start to separate,” Joglar, Program Director, Clinical Cardiac Electrophysiology Fellowship Program, The University of Texas Southwestern Medical Center, Dallas, continued, “but by then you have already made the decision to anticoagulate.”

More recently, Kotecha and colleagues conducted a population cohort study of the electronic healthcare records of UK primary care patients treated between 2005 and 2020, and identified 78,852 with AF; more than a third were women.

Their analysis, published on September 1, showed that women had a lower adjusted rate of the primary composite outcome of all-cause mortality, ischemic stroke, or arterial thromboembolism, driven by a reduced mortality rate.

“Removal of gender from clinical risk scoring could simplify the approach to which patients with AF should be offered oral anticoagulation,” Kotecha and colleagues concluded.

Joglar clarified that “women are at increased risk for stroke than men” overall, but by the time that risk “becomes manifest, other risk factors have come into play, and they have already met the criteria for anticoagulation.”

The authors of the latest ESC guideline therefore concluded that the “inclusion of gender complicates clinical practice both for healthcare professionals and patients.” Their solution was to remove the question of gender for decisions over initiating oral anticoagulant therapy in clinical practice altogether.

This includes individuals who identify as transgender or are undergoing sex hormone therapy, as all the experts interviewed by Medscape Medical News agreed that there is currently insufficient evidence to know if that affects stroke risk.

Instead, guidelines state that the drugs are “recommended in those with a CHA2DS2-VA score of 2 or more and should be considered in those with a CHA2DS2-VA score of 1, following a patient-centered and shared care approach.”

“Dropping the gender part of the risk score is not really a substantial change” from previous ESC or other guidelines, as different points were required in the past to recommend anticoagulants for women and men, Kotecha said, adding that “making the approach easier for clinicians may avoid penalizing women as well as nonbinary and transgender patients.”

Anne B. Curtis, MD, SUNY Distinguished Professor, Department of Medicine, Jacobs School of Medicine & Biomedical Sciences, University at Buffalo in New York, agreed.

Putting aside the question of female sex, she said that there are not a lot of people under the age of 65 years with “absolutely no risk factors,” and so, “if the only reason you would anticoagulate” someone of that age is because they are a woman that “doesn’t make a lot of sense to me.”

The ESC guidelines are “trying to say, ‘look at the other risk factors, and if anything is there, go ahead and anticoagulate,” Curtis said in an interview.

“It’s actually a very thoughtful decision,” Tedrow said, and not “intended to discount risk in women.” Rather, it’s a statement that acknowledges the problem of recommending anticoagulation therapy in women “for whom it is not appropriate.”

Joglar pointed out that that recommendation, although not characterized in the same way, was in fact included in the 2023 US guidelines.

“We wanted to use a more nuanced approach,” he said, and move away from using CHA2DS2–VASc as the prime determinant of whether to start oral anticoagulation and towards a magnitude risk assessment, in which female sex is seen as a risk modifier.

“The Europeans and the Americans are looking at the same data, so we often reach the same conclusions,” Joglar said, although “we sometimes use different wordings.”

Overall, Kotecha expressed the hope that the move “will lead to better implementation of guidelines, at the end of the day.”

“That’s all we can hope for: Patients will be offered a more individualized approach, leading to more appropriate use of treatment in the right patients.”

The newer direct oral anticoagulation is “a much simpler therapy,” he added. “There is very little monitoring, a similar risk of bleeding as aspirin, and yet the ability to largely prevent the high rate of stroke and thromboembolism associated with atrial fibrillation.”

“So, it’s a big ticket item for our communities and public health, particularly as atrial fibrillation is expected to double in prevalence in the next few decades and evidence is building that it can lead to vascular dementia in the long-term.”

No funding was declared. Kotecha declares relationships with Bayer, Protherics Medicines Development, Boston Scientific, Daiichi Sankyo, Boehringer Ingelheim, BMS-Pfizer Alliance, Amomed, MyoKardia. Curtis declared relationships with Janssen Pharmaceuticals, Medtronic, Abbott. Joglar declared no relevant relationships. Tedrow declared no relevant relationships.

The European Society of Cardiology (ESC) caused a stir when they recommended in their latest atrial fibrillation (AF) management guideline that gender no longer be included in the decision to initiate oral anticoagulation therapy.

The move aims to level the playing field between men and women and follows a more nuanced understanding of stroke risk in patients with AF, said experts. It also acknowledges the lack of evidence in people receiving cross-sex hormone therapy.

In any case, the guidelines, developed in collaboration with the European Association for Cardio-Thoracic Surgery and published by the European Heart Journal on August 30, simply follow 2023’s US recommendations, they added.

 

One Size Does Not Fit All

So, what to the ESC guidelines actually say?

They underline that, if left untreated, the risk for ischemic stroke is increased fivefold in patients with AF, and the “default approach should therefore be to provide oral anticoagulation to all eligible AF patients, except those at low risk for incident stroke or thromboembolism.”

However, the authors note that there is a lack of strong evidence on how to apply the current risk scores to help inform that decision in real-world patients.

Dipak Kotecha, MBChB, PhD, Professor of Cardiology at the University of Birmingham and University Hospitals Birmingham NHS Foundation Trust, Birmingham, England, and senior author of the ESC guidelines, said in an interview that “the available scores have a relatively poor ability to accurately predict which patients will have a stroke or thromboembolic event.”

Instead, he said “a much better approach is for healthcare professionals to look at each patient’s individual risk factors, using the risk scores to identify those patients that might not benefit from oral anticoagulant therapy.”

For these guidelines, the authors therefore wanted to “move away from a one-size-fits-all” approach, Kotecha said, and instead ensure that more patients can benefit from the new range of direct oral anticoagulants (DOACs) that are easier to take and with much lower chance of side effects or major bleeding.

To achieve this, they separated their clinical recommendations from any particular risk score, and instead focused on the practicalities of implementation.

 

Risk Modifier Vs Risk Factor

To explain their decision the authors highlight that “the most popular risk score” is the CHA2DS2–VASc, which gives a point for female sex, alongside factors such as congestive heart failure, hypertension, and diabetes mellitus, and a sliding scale of points for increasing age.

Kotecha pointed out the score was developed before the DOACs were available and may not account for how risk factors have changed in recent decades.

The result is that CHA2DS2–VASc gives the same number of points to an individual with heart failure or prior transient ischemic attack as to a woman aged less than 65 years, “but the magnitude of increased risk is not the same,” Usha Beth Tedrow, MD, Associate Professor of Medicine, Brigham and Women’s Hospital, Boston, Massachusetts, said in an interview.

As far back as 2018, it was known that “female sex is a risk modifier, rather than a risk factor for stroke in atrial fibrillation,” noted Jose Joglar, MD, lead author of the 2023 ACC/AHA/ACCP/HRS Guideline for the Diagnosis and Management of Atrial Fibrillation said in an interview.

Danish national registry study involving 239,671 AF patients treated between 1997 and 2015, nearly half of whom were women, showed that, at a CHA2DS2–VASc score of 0, the “risk of stroke between men and women is absolutely the same,” he said.

“It is not until after a CHA2DS2–VASc score of 2 that the curves start to separate,” Joglar, Program Director, Clinical Cardiac Electrophysiology Fellowship Program, The University of Texas Southwestern Medical Center, Dallas, continued, “but by then you have already made the decision to anticoagulate.”

More recently, Kotecha and colleagues conducted a population cohort study of the electronic healthcare records of UK primary care patients treated between 2005 and 2020, and identified 78,852 with AF; more than a third were women.

Their analysis, published on September 1, showed that women had a lower adjusted rate of the primary composite outcome of all-cause mortality, ischemic stroke, or arterial thromboembolism, driven by a reduced mortality rate.

“Removal of gender from clinical risk scoring could simplify the approach to which patients with AF should be offered oral anticoagulation,” Kotecha and colleagues concluded.

Joglar clarified that “women are at increased risk for stroke than men” overall, but by the time that risk “becomes manifest, other risk factors have come into play, and they have already met the criteria for anticoagulation.”

Periodontitis Management: GPs Should Play a Role

Article Type
Changed
Thu, 11/14/2024 - 22:38

Periodontitis is a chronic inflammatory disease that triggers a local immuno-inflammatory response, potentially leading to periodontal tissue destruction and tooth loss. Affecting 1.1 billion people worldwide, periodontitis is recognized as a significant public health issue. It is also linked to a number of other conditions, such as diabetes, cardiovascular disease, and respiratory disorders. The European Federation of Periodontology recently published a consensus report recommending that the optimal management of periodontitis should involve a collaboration between general practitioners (GPs) and oral health professionals.

Diabetes and Periodontitis

A bidirectional association exists between diabetes and periodontitis. Hyperglycemia accelerates periodontitis progression by promoting inflammation and hindering the healing process, while periodontitis is associated with higher hemoglobin A1c levels in patients with diabetes and an increased risk for diabetes development in others. Intervention studies have demonstrated the positive effect of glycemic control on periodontitis and vice versa, with periodontal treatment improving A1c levels.

GPs can raise awareness of the links between these conditions as well as emphasize the benefits of addressing both metabolic and periodontal abnormalities. They should refer patients with diabetes to oral health specialists and look for signs of periodontitis, such as bleeding gums and loose teeth, in patients with diabetes and those with prediabetes.

 

Cardiovascular Diseases and Periodontitis

Cardiovascular diseases and periodontitis are linked by their epidemiological associations and common biologic mechanisms. This connection can be explained by some of their shared risk factors, such as smoking and systemic inflammatory pathways. Although no intervention studies have shown a direct reduction in cardiovascular risk from periodontal care, two studies have demonstrated improvements in surrogate markers such as blood pressure and arterial stiffness. GPs should inquire about symptoms of periodontitis in cardiovascular patients and, if necessary, refer them to oral health specialists. Periodontal treatments, whether surgical or nonsurgical, pose no risk for patients receiving well-managed secondary preventive treatments.

 

Respiratory Diseases and Periodontitis

The primary evidence linking periodontitis with chronic respiratory diseases concerns chronic obstructive pulmonary disease (COPD). Individuals with periodontitis have a 33% higher risk of developing COPD, and patients with COPD and periodontitis may experience a greater decline in lung function. An established association also exists between periodontitis and obstructive sleep apnea, although the data remain inconclusive regarding a link with asthma. GPs should encourage patients with COPD to quit smoking, as it benefits both respiratory and oral health.

Finally, based on meta-analyses of COVID-19, experts note significant associations between periodontitis and the need for assisted ventilation or the risk for death during a COVID-19 infection.

Study Finds No Significant Effect of Low-Dose Oral Minoxidil on BP

Article Type
Changed
Wed, 11/13/2024 - 09:27

 

TOPLINE:

Low-dose oral minoxidil (LDOM), used off-label to treat alopecia, does not significantly affect blood pressure (BP) in patients with alopecia, but is associated with a slight increase in heart rate and a 5% incidence of hypotensive symptoms.

METHODOLOGY:

  • Researchers conducted a systematic review and meta-analysis of 16 studies, which involved 2387 patients with alopecia (60.7% women) who received minoxidil, a vasodilator originally developed as an antihypertensive, at doses of 5 mg or less per day.
  • Outcomes included changes in mean arterial pressure, systolic BP, diastolic BP, and heart rate.
  • Mean differences were calculated between pretreatment and posttreatment values.

TAKEAWAY:

  • Hypotensive symptoms were reported in 5% patients, with no significant hypotensive episodes. About 1.8% patients experienced lightheadedness or syncope, 1.2% experienced dizziness, 0.9% had tachycardia, and 0.8% had palpitations.
  • LDOM did not significantly alter systolic BP (mean difference, –0.13; 95% CI, –2.67 to 2.41), diastolic BP (mean difference, –1.25; 95% CI, –3.21 to 0.71), and mean arterial pressure (mean difference, –1.92; 95% CI, –4.00 to 0.17).
  • LDOM led to a significant increase in heart rate (mean difference, 2.67 beats/min; 95% CI, 0.34-5.01), a difference the authors wrote would “likely not be clinically significant for most patients.”
  • Hypertrichosis was the most common side effect (59.6%) and reason for stopping treatment (accounting for nearly 35% of discontinuations).

IN PRACTICE:

“LDOM appears to be a safe treatment for alopecia with no significant impact on blood pressure,” the authors wrote, noting that the study “addresses gaps in clinical knowledge involving LDOM.” Based on their results, they recommended that BP and heart rate “do not need to be closely monitored in patients without prior cardiovascular risk history.”

SOURCE:

The study was led by Matthew Chen, BS, Stony Brook Dermatology in New York. It was published online in The Journal of the American Academy of Dermatology.

LIMITATIONS:

The studies included had small sample sizes and retrospective designs, which may limit the reliability of the findings. Additional limitations include the absence of control groups, a potential recall bias in adverse effect reporting, and variability in dosing regimens and BP monitoring. 

DISCLOSURES:

The authors reported no external funding or conflicts of interest.

TOPLINE:

Low-dose oral minoxidil (LDOM), used off-label to treat alopecia, does not significantly affect blood pressure (BP) in patients with alopecia, but is associated with a slight increase in heart rate and a 5% incidence of hypotensive symptoms.

METHODOLOGY:

  • Researchers conducted a systematic review and meta-analysis of 16 studies, which involved 2387 patients with alopecia (60.7% women) who received minoxidil, a vasodilator originally developed as an antihypertensive, at doses of 5 mg or less per day.
  • Outcomes included changes in mean arterial pressure, systolic BP, diastolic BP, and heart rate.
  • Mean differences were calculated between pretreatment and posttreatment values.

TAKEAWAY:

  • Hypotensive symptoms were reported in 5% patients, with no significant hypotensive episodes. About 1.8% patients experienced lightheadedness or syncope, 1.2% experienced dizziness, 0.9% had tachycardia, and 0.8% had palpitations.
  • LDOM did not significantly alter systolic BP (mean difference, –0.13; 95% CI, –2.67 to 2.41), diastolic BP (mean difference, –1.25; 95% CI, –3.21 to 0.71), and mean arterial pressure (mean difference, –1.92; 95% CI, –4.00 to 0.17).
  • LDOM led to a significant increase in heart rate (mean difference, 2.67 beats/min; 95% CI, 0.34-5.01), a difference the authors wrote would “likely not be clinically significant for most patients.”
  • Hypertrichosis was the most common side effect (59.6%) and reason for stopping treatment (accounting for nearly 35% of discontinuations).

IN PRACTICE:

“LDOM appears to be a safe treatment for alopecia with no significant impact on blood pressure,” the authors wrote, noting that the study “addresses gaps in clinical knowledge involving LDOM.” Based on their results, they recommended that BP and heart rate “do not need to be closely monitored in patients without prior cardiovascular risk history.”

Study Finds No Increased MACE Risk for JAK Inhibitors in Patients With Atopic Dermatitis

Article Type
Changed
Tue, 11/12/2024 - 09:40

Janus kinase inhibitors (JAKis) do not appear to increase the risk for major adverse cardiovascular events (MACE) among people with atopic dermatitis (AD) treated in a real-world setting, suggested the results of a large, US-based, retrospective cohort study.

This holds true even in individuals aged 50 years or older, whose age puts them at increased cardiovascular (CV) risk, said Amina El Ayadi, PhD, of the University of Texas Medical Branch at Galveston. He presented the findings at the recent European Academy of Dermatology and Venereology (EADV) 2024 Congress.

Specifically, the analysis looked at treatment with the oral JAK1 inhibitors upadacitinib (Rinvoq) and abrocitinib (Cibinqo), both approved for treating AD in the United States, and found that the relative risk for MACE, such as acute myocardial infarction, cardiac arrest, stroke, or acute deep vein thrombosis, was ≤ 1.0 compared with those not treated with a JAKi.

Similarly, the relative risk for other CV safety endpoints, such as having an abnormal ECG or pericardial effusion, was also around 1.0. There was a slight increase in the relative risk for arrhythmias, peripheral edema, angina pectoris, or heart failure, but no value went > 1.6 and CIs spanned 1.0, indicating the results lack statistical significance.
 

Reassurance for Dermatologists?

“This suggests that oral administration of these drugs to the patient with atopic dermatitis does not increase the risk of major adverse cardiac events, and dermatologists, based on our data, can safely consider JAK inhibitors for treating moderate to severe dermatitis, even in patients with high risk for these diseases,” El Ayadi said during a late-breaking news session at the meeting.

Yolanda Gilaberte Calzada, MD, PhD, head of the Dermatology Department at Miguel Servet University Hospital in Zaragoza, Spain, who was one of the chairs for the session, said that this was “very good news for us.”

Gilaberte Calzada, president of the Spanish Academy of Dermatology and Venereology, asked if there were any data on the duration of treatment with the two JAKis included in the analysis. El Ayadi said that this was something that would be looked at in future data analyses.

Gilaberte Calzada also observed that because the CIs were wide, with more time, “we will have more defined data.”
 

Analyses Overview

For the two analyses — one in the overall population of patients with AD and the other in those aged 50 years or older — electronic medical record (EMR) data from the TriNetX Research Network were used. This is a global, federated health research network that contains EMRs for more than 275 million patients from over 120 healthcare organizations, El Ayadi explained.

To perform the analyses, the research team queried the TriNetX database to find all patients diagnosed with AD via the International Classification of Diseases, Tenth Revision code L20. They then determined if patients had been treated with JAKi or not, and specifically, with upadacitinib or abrocitinib. Those who had not received any JAKi treatment were the control population.

For the first analysis, no age-specific filter was applied. The investigators identified 1674 people with AD who had been treated with the JAKis and around 1.2 million who had not. Propensity score matching, based on age at diagnosis, biologic sex, and CV comorbidities, was performed to give a total of 1674 patients who had and 1674 who had not been treated with these medications.

In the second analysis, only those aged 50 years or older were considered; 875 patients who had received JAKi treatment were identified and around 250,000 who had not. Propensity score matching based on the same variables gave two groups of 875 people who had or had not taken a JAKi.

Queried over the age cutoff used, El Ayadi noted, “We did an analysis looking at patients 65 and older. However, we came up with lower patient numbers. … We do have this data, and we did not see any significant risk.”

The study was independently supported. El Ayadi and Gilaberte Calzada reported no conflicts of interest in relation to the presented findings.

Rituximab Not Inferior to Cyclophosphamide in Pediatric Vasculitis

Article Type
Changed
Tue, 11/12/2024 - 11:42

 

TOPLINE:

Rituximab and cyclophosphamide are equally effective in achieving remission or low disease activity rates in childhood-onset antineutrophil cytoplasmic antibody–associated vasculitis (AAV), and those who received rituximab required a significantly lower steroid dose than those who received cyclophosphamide or a combination therapy.

METHODOLOGY:

  • Researchers evaluated the efficacy of rituximab, cyclophosphamide, or a combination of both in pediatric patients diagnosed with granulomatosis with polyangiitis (GPA) or microscopic polyangiitis.
  • A total of 104 patients (median age at diagnosis, 14 years; 67% girls) were included from A Registry of Childhood Vasculitis; the majority had a diagnosis of GPA (81%) and renal involvement (87%). Overall, induction therapy involved rituximab for 43%, cyclophosphamide for 46%, and a combination of both for 11% patients.
  • The primary endpoint was the rate of achieving remission (Pediatric Vasculitis Activity Score [PVAS] of 0) or low disease activity (PVAS ≤ 2) at the post-induction visit (4-6 months after diagnosis).
  • The secondary endpoints were the degree of disease-related damage at 12- and 24-month visits and rates of drug-related hospitalization occurring between the diagnosis and post-induction visits.

TAKEAWAY:

  • At the post-induction visit, 63% patients achieved remission or low disease activity, with the rates being similar between patients who received rituximab and those who received cyclophosphamide (64% vs 62%).
  • Patients treated with rituximab required a significantly lower median steroid dose (0.13 mg/kg per day) than those treated with cyclophosphamide (0.3 mg/kg per day) or the combination therapy (0.3 mg/kg per day; P < .001) at the post-induction visit.
  • Overall, 61% and 56% patients receiving rituximab and cyclophosphamide, respectively, had disease-related damage measure on the Pediatric Vasculitis Damage Index at the 12-month visit; however, the degree of damage was low.
  • The percentage of patients requiring hospitalization was higher in the rituximab group than in the cyclophosphamide group (22% vs 10%), primarily stemming from drug- or infection-related causes (11% vs 2%).

IN PRACTICE:

“The results of this study may assist with current clinical decision-making with regard to the choice of induction medications in childhood-onset AAV and will complement the ongoing [Childhood Arthritis and Rheumatology Research Alliance] prospective [consensus treatment plans] study,” the authors wrote.

SOURCE:

This study was led by Samuel J. Gagne, MD, Children’s Hospital of Pittsburgh, University of Pittsburgh Medical Center in Pennsylvania, and was published online in Arthritis Care & Research.

LIMITATIONS:

Study limitations included the inconsistencies in glucocorticoid dosing, which may have affected remission rates. Moreover, data on the adverse events not requiring hospitalization and long-term adverse events were not captured.

DISCLOSURES:

This study received funding through a Nationwide Children’s Hospital intramural grant award. The authors reported no potential conflicts of interest.

How Extreme Rainfall Amplifies Health Risks

Article Type
Changed
Wed, 11/06/2024 - 12:34

Climate change is intensifying the variability of precipitation caused by extreme daily and overall rainfall events. Awareness of the effects of these events is crucial for understanding the complex health consequences of climate change. The connections between health and climate have been recognized by physicians and patients even when climatology did not have the status of an exact science. Physicians have often advised their patients to move to a better climate, and when they did, the recommendation was rarely based on precise scientific knowledge. However, the benefits of changing environments were often so evident that they were indisputable.

Today, advanced models, satellite imagery, and biological approaches such as environmental epigenetics are enhancing our understanding of health risks related to climate change.
 

Extreme Rainfall and Health

The increase in precipitation variability is linked to climate warming, which leads to higher atmospheric humidity and extreme rainfall events. These manifestations can cause rapid weather changes, increasing interactions with harmful aerosols and raising the risk for various cardiovascular and respiratory conditions. However, a full understanding of the association between rain and health has been hindered by conflicting results and methodological issues (limited geographical locations and short observation durations) in studies.

The association between rainfall intensity and health effects is likely nonlinear. Moderate precipitation can mitigate summer heat and help reduce air pollution, an effect that may lower some environmental health risks. Conversely, intense, low-frequency, short-duration rainfall events can have particularly harmful effects on health, as such events can trigger rapid weather changes, increased proliferation of pathogens, and a rise in the risk of various pollutants, potentially exacerbating health conditions.
 

Rain and Mortality

Using an intensity-duration-frequency model of three rainfall indices (high intensity, low frequency, short duration), a study published in October 2024 combined these with mortality data from 34 countries or regions. Researchers estimated associations between mortality (all cause, cardiovascular, and respiratory) and rainfall events with different return periods (the average time expected before an extreme event of a certain magnitude occurs again) and crucial effect modifiers, including climatic, socioeconomic, and urban environmental conditions.

The analysis included 109,954,744 deaths from all causes; 31,164,161 cardiovascular deaths; and 11,817,278 respiratory deaths. During the study period, from 1980 to 2020, a total of 50,913 rainfall events with a 1-year return period, 8362 events with a 2-year return period, and 3301 events with a 5-year return period were identified.

The most significant finding was a global positive association between all-cause mortality and extreme rainfall events with a 5-year return period. One day of extreme rainfall with a 5-year return period was associated with a cumulative relative risk (RRc) of 1.08 (95% CI, 1.05-1.11) for daily mortality from all causes. Rainfall events with a 2-year return period were associated with increased daily respiratory mortality (RRc, 1.14), while no significant effect was observed for cardiovascular mortality during the same period. Rainfall events with a 5-year return period were associated with an increased risk for both cardiovascular mortality (RRc, 1.05) and respiratory mortality (RRc, 1.29), with the respiratory mortality being significantly higher.
 

Points of Concern

According to the authors, moderate to high rainfall can exert protective effects through two main mechanisms: Improving air quality (rainfall can reduce the concentration of particulate matter 2.5 cm in diameter or less in the atmosphere) and behavioral changes in people (more time spent in enclosed environments, reducing direct exposure to outdoor air pollution and nonoptimal temperatures). As rainfall intensity increases, the initial protective effects may be overshadowed by a cascade of negative impacts including:

  • Critical resource disruptions: Intense rainfall can cause severe disruptions to access to healthcare, infrastructure damage including power outages, and compromised water and food quality.
  • Physiological effects: Increased humidity levels facilitate the growth of airborne pathogens, potentially triggering allergic reactions and respiratory issues, particularly in vulnerable individuals. Rapid shifts in atmospheric pressure and temperature fluctuations can lead to cardiovascular and respiratory complications.
  • Indirect effects: Extreme rainfall can have profound effects on mental health, inducing stress and anxiety that may exacerbate pre-existing mental health conditions and indirectly contribute to increased overall mortality from nonexternal causes.

The intensity-response curves for the health effects of heavy rainfall showed a nonlinear trend, transitioning from a protective effect at moderate levels of rainfall to a risk for severe harm when rainfall intensity became extreme. Additionally, the significant effects of extreme events were modified by various types of climate and were more pronounced in areas characterized by low variability in precipitation or sparse vegetation cover.

The study demonstrated that various local factors, such as climatic conditions, climate type, and vegetation cover, can potentially influence cardiovascular and respiratory mortality and all-cause mortality related to precipitation. The findings may help physicians convey to their patients the impact of climate change on their health.

The analysis included 109,954,744 deaths from all causes; 31,164,161 cardiovascular deaths; and 11,817,278 respiratory deaths. During the study period, from 1980 to 2020, a total of 50,913 rainfall events with a 1-year return period, 8362 events with a 2-year return period, and 3301 events with a 5-year return period were identified.

The most significant finding was a global positive association between all-cause mortality and extreme rainfall events with a 5-year return period. One day of extreme rainfall with a 5-year return period was associated with a cumulative relative risk (RRc) of 1.08 (95% CI, 1.05-1.11) for daily mortality from all causes. Rainfall events with a 2-year return period were associated with increased daily respiratory mortality (RRc, 1.14), while no significant effect was observed for cardiovascular mortality during the same period. Rainfall events with a 5-year return period were associated with an increased risk for both cardiovascular mortality (RRc, 1.05) and respiratory mortality (RRc, 1.29), with the respiratory mortality being significantly higher.
 

Points of Concern

According to the authors, moderate to high rainfall can exert protective effects through two main mechanisms: Improving air quality (rainfall can reduce the concentration of particulate matter 2.5 cm in diameter or less in the atmosphere) and behavioral changes in people (more time spent in enclosed environments, reducing direct exposure to outdoor air pollution and nonoptimal temperatures). As rainfall intensity increases, the initial protective effects may be overshadowed by a cascade of negative impacts including:

  • Critical resource disruptions: Intense rainfall can cause severe disruptions to access to healthcare, infrastructure damage including power outages, and compromised water and food quality.
  • Physiological effects: Increased humidity levels facilitate the growth of airborne pathogens, potentially triggering allergic reactions and respiratory issues, particularly in vulnerable individuals. Rapid shifts in atmospheric pressure and temperature fluctuations can lead to cardiovascular and respiratory complications.
  • Indirect effects: Extreme rainfall can have profound effects on mental health, inducing stress and anxiety that may exacerbate pre-existing mental health conditions and indirectly contribute to increased overall mortality from nonexternal causes.

The intensity-response curves for the health effects of heavy rainfall showed a nonlinear trend, transitioning from a protective effect at moderate levels of rainfall to a risk for severe harm when rainfall intensity became extreme. Additionally, the significant effects of extreme events were modified by various types of climate and were more pronounced in areas characterized by low variability in precipitation or sparse vegetation cover.

The study demonstrated that various local factors, such as climatic conditions, climate type, and vegetation cover, can potentially influence cardiovascular and respiratory mortality and all-cause mortality related to precipitation. The findings may help physicians convey to their patients the impact of climate change on their health.

Climate change is intensifying the variability of precipitation caused by extreme daily and overall rainfall events. Awareness of the effects of these events is crucial for understanding the complex health consequences of climate change. The connections between health and climate have been recognized by physicians and patients even when climatology did not have the status of an exact science. Physicians have often advised their patients to move to a better climate, and when they did, the recommendation was rarely based on precise scientific knowledge. However, the benefits of changing environments were often so evident that they were indisputable.

Today, advanced models, satellite imagery, and biological approaches such as environmental epigenetics are enhancing our understanding of health risks related to climate change.
 

Extreme Rainfall and Health

The increase in precipitation variability is linked to climate warming, which leads to higher atmospheric humidity and extreme rainfall events. These manifestations can cause rapid weather changes, increasing interactions with harmful aerosols and raising the risk for various cardiovascular and respiratory conditions. However, a full understanding of the association between rain and health has been hindered by conflicting results and methodological issues (limited geographical locations and short observation durations) in studies.

The association between rainfall intensity and health effects is likely nonlinear. Moderate precipitation can mitigate summer heat and help reduce air pollution, an effect that may lower some environmental health risks. Conversely, intense, low-frequency, short-duration rainfall events can have particularly harmful effects on health, as such events can trigger rapid weather changes, increased proliferation of pathogens, and a rise in the risk of various pollutants, potentially exacerbating health conditions.

On Second Thought: Aspirin for Primary Prevention — What We Really Know

This transcript has been edited for clarity

Aspirin. Once upon a time, everybody over age 50 years was supposed to take a baby aspirin. Now we make it a point to tell people to stop. What is going on?  

Our recommendations vis-à-vis aspirin have evolved at a dizzying pace. The young’uns watching us right now don’t know what things were like in the 1980s. The Reagan era was a wild, heady time where nuclear war was imminent and we didn’t prescribe aspirin to patients. 

That only started in 1988, which was a banner year in human history. Not because a number of doves were incinerated by the lighting of the Olympic torch at the Seoul Olympics — look it up if you don’t know what I’m talking about — but because 1988 saw the publication of the ISIS-2 trial, which first showed a mortality benefit to prescribing aspirin post–myocardial infarction (MI).

Giving patients aspirin during or after a heart attack is not controversial. It’s one of the few things in this business that isn’t, but that’s secondary prevention — treating somebody after they develop a disease. Primary prevention, treating them before they have their incident event, is a very different ballgame. Here, things are messy. 

For one thing, the doses used have been very inconsistent. We should point out that the reason for 81 mg of aspirin is very arbitrary and is rooted in the old apothecary system of weights and measurements. A standard dose of aspirin was 5 grains, where 20 grains made 1 scruple, 3 scruples made 1 dram, 8 drams made 1 oz, and 12 oz made 1 lb - because screw you, metric system. Therefore, 5 grains was 325 mg of aspirin, and 1 quarter of the standard dose became 81 mg if you rounded out the decimal. 

People have tried all kinds of dosing structures with aspirin prophylaxis. The Physicians’ Health Study used a full-dose aspirin, 325 mg every 2 days, while the Hypertension Optimal Treatment (HOT) trial tested 75 mg daily and the Women’s Health Study tested 100 mg, but every other day. 

Ironically, almost no one has studied 81 mg every day, which is weird if you think about it. The bigger problem here is not the variability of doses used, but the discrepancy when you look at older vs newer studies.

Older studies, like the Physicians’ Health Study, did show a benefit, at least in the subgroup of patients over age 50 years, which is probably where the “everybody over 50 should be taking an aspirin” idea comes from, at least as near as I can tell. 

More recent studies, like the Women’s Health Study, ASPREE, or ASPIRE, didn’t show a benefit. I know what you’re thinking: Newer stuff is always better. That’s why you should never trust anybody over age 40 years. The context of primary prevention studies has changed. In the ‘80s and ‘90s, people smoked more and we didn’t have the same medications that we have today. We talked about all this in the beta-blocker video to explain why beta-blockers don’t seem to have a benefit post MI.

We have a similar issue here. The magnitude of the benefit with aspirin primary prevention has decreased because we’re all just healthier overall. So, yay! Progress! Here’s where the numbers matter. No one is saying that aspirin doesn’t help. It does. 

If we look at the 2019 meta-analysis published in JAMA, there is a cardiovascular benefit. The numbers bear that out. I know you’re all here for the math, so here we go. Aspirin reduced the composite cardiovascular endpoint from 65.2 to 60.2 events per 10,000 patient-years; or to put it more meaningfully in absolute risk reduction terms, because that’s my jam, an absolute risk reduction of 0.41%, which means a number needed to treat of 241, which is okay-ish. It’s not super-great, but it may be justifiable for something that costs next to nothing. 

The tradeoff is bleeding. Major bleeding increased from 16.4 to 23.1 bleeds per 10,000 patient-years, or an absolute risk increase of 0.47%, which is a number needed to harm of 210. That’s the problem. Aspirin does prevent heart disease. The benefit is small, for sure, but the real problem is that it’s outweighed by the risk of bleeding, so you’re not really coming out ahead. 

The real tragedy here is that the public is locked into this idea of everyone over age 50 years should be taking an aspirin. Even today, even though guidelines have recommended against aspirin for primary prevention for some time, data from the National Health Interview Survey sample found that nearly one in three older adults take aspirin for primary prevention when they shouldn’t be. That’s a large number of people. That’s millions of Americans — and Canadians, but nobody cares about us. It’s fine. 

That’s the point. We’re not debunking aspirin. It does work. The benefits are just really small in a primary prevention population and offset by the admittedly also really small risks of bleeding. It’s a tradeoff that doesn’t really work in your favor.

But that’s aspirin for cardiovascular disease. When it comes to cancer or DVT prophylaxis, that’s another really interesting story. We might have to save that for another time. Do I know how to tease a sequel or what?

Labos, a cardiologist at Kirkland Medical Center, Montreal, Quebec, Canada, has disclosed no relevant financial relationships.
