Evolocumab safe and effective in pediatric FH
The PCSK9 monoclonal antibody evolocumab (Repatha) was well tolerated and effectively lowered LDL cholesterol by 38% compared with placebo in a randomized controlled trial in pediatric patients with heterozygous familial hypercholesterolemia (FH) already taking statins with or without ezetimibe.
“HAUSER-RCT is the largest study and the first placebo-controlled randomized trial of a PCSK9 inhibitor in pediatric FH,” senior author Daniel Gaudet, MD, PhD, Universite de Montreal, said in an interview.
“The study showed good safety and efficacy of the drug in this population, with an excellent 44% reduction in LDL cholesterol compared with 6% in the placebo group.”
The trial also found evolocumab to be well tolerated in this group, with adverse effects similar in the active and placebo groups.
“Some people have wondered about using a drug with a monthly injection in a pediatric population, but this was not an issue in our study,” Dr. Gaudet said. “The idea of a monthly injection was well received, and no patient withdrew because of this.”
The HAUSER-RCT trial was presented on Aug. 29 at the virtual annual congress of the European Society of Cardiology (ESC Congress 2020) and simultaneously published online in the New England Journal of Medicine.
“With patients recruited from 23 countries in five continents, the study provides an accurate picture of the safety and efficacy of evolocumab in pediatric FH patients worldwide,” Dr. Gaudet said.
The 24-week, randomized, double-blind, placebo-controlled trial involved 157 patients aged 10-17 years with heterozygous FH already taking statins with or without ezetimibe and who had an LDL cholesterol level of 130 mg/dL or more and a triglyceride level of 400 mg/dL or less.
They were randomly assigned in a 2:1 ratio to receive monthly subcutaneous injections of evolocumab (420 mg) or placebo.
Results showed that at week 24, the mean percentage change from baseline in LDL cholesterol level was −44.5% in the evolocumab group and −6.2% in the placebo group, giving a difference of −38.3 percentage points (P < .001).
The absolute change in the LDL cholesterol level was −77.5 mg/dL in the evolocumab group and −9.0 mg/dL in the placebo group, giving a difference of −68.6 mg/dL (P < .001).
Results for all secondary lipid variables were significantly better with evolocumab than with placebo. The incidence of adverse events that occurred during the treatment period was similar in the evolocumab and placebo groups. Laboratory abnormalities did not differ between groups.
Dr. Gaudet noted that FH is the most common genetic disease worldwide, affecting 1 in 250 people. “It is very treatable, so it is important to identify these patients, but it is massively underdiagnosed, with only around 15%-20% of patients with the condition having been identified,” he said.
“The vast majority of pediatric FH patients can reach target LDL levels with statins and ezetimibe, but there are 5%-10% of patients who may need additional therapy. We have now shown that evolocumab is safe and effective for these patients and can be used to fill this gap,” Dr. Gaudet said. “We can now say that we can cover all situations in treating FH whatever the severity of the disease.”
However, the challenge remains to improve the diagnosis of FH. “If there is one person with FH in a family, then it is essential that the whole extended family is tested. Our toolbox for treating this condition is now sufficiently effective, so there is no reason not to diagnose this disease,” Dr. Gaudet stressed.
The HAUSER-RCT study was supported by Amgen. Gaudet reports grants and personal fees from Amgen during the conduct of the study.

Vitamin D pearls
Case: A 56-year-old man with a history of type 2 diabetes, hypertension, hyperlipidemia, and obesity calls clinic to discuss concerns about COVID-19, stating: “I want to do everything I can to reduce my risk of infection.” In addition to physical distancing, mask wearing, hand hygiene, and control of chronic conditions, which of the following supplements would you recommend for this patient?
1. Coenzyme Q10 160 mg twice a day
2. Vitamin D 2,000 IU daily
3. Vitamin E 400 IU daily
4. Vitamin B12 1,000 mcg daily
Of these choices, vitamin D supplementation is likely the best option, based on the limited data that is available.
Risk factors for worse COVID-19 outcome, such as older age, obesity, and more pigmented skin are also risk factors for vitamin D deficiency. This makes the study of vitamin D and COVID-19 both challenging and relevant.
In a recent study of 7,807 people living in Israel, Merzon and colleagues found that low plasma vitamin D level was an independent risk factor for COVID-19 infection. Mean plasma vitamin D level was significantly lower among those who tested positive for COVID-19 (19.00 ng/mL) than negative (20.55 ng/ mL). After controlling for demographic variables and several medical conditions, the adjusted odds ratio of COVID-19 infection in those with lower vitamin D was 1.45 (95% confidence interval, 1.08-1.95; P < .001). However, the odds of hospitalization for COVID-19 was not significantly associated with vitamin D level.1
Prior studies have also looked at vitamin D and respiratory infection. Martineau and colleagues analyzed 25 randomized, controlled trials with a pooled number of 11,321 individuals, including healthy ones and those with comorbidities, and found that oral vitamin D supplementation in daily or weekly doses had a protective effect against acute respiratory infection (adjusted odds ratio, 0.88; 95% CI, 0.81-0.96; P < .001). Patients with vitamin D deficiency (less than 25 nmol/L) experienced the most protective benefit. Vitamin D did not influence respiratory infection outcome.2
These studies suggest an adequate vitamin D level may be protective against infection with COVID-19, but who will benefit from vitamin D supplementation, and in what dose? Per U.S. Preventive Services Task Force guidelines, there is insufficient evidence to recommend screening for vitamin D deficiency in asymptomatic adults. Regarding daily dietary intake, the Institute of Medicine recommends 600 IU for persons aged 1-70, and 800 IU for those aged over 70 years. Salmon (447 IU per 3 oz serving), tuna (154 IU), and fortified milk (116 IU) are among the most vitamin D–rich foods.3 The recommended upper level of intake is 4,000 IU/day.
Too much of a good thing?
Extra vitamin D is stored in adipose tissue. If it builds up over time, storage sites may be overwhelmed, causing a rise in serum D level. While one might expect a subsequent rise in calcium levels, studies have shown this happens inconsistently, and at very high vitamin D levels, over 120 ng/mL.4 Most people would have to take at least 50,000 IU daily for several months to see an effect. The main adverse outcome of vitamin D toxicity is kidney stones, mediated by increased calcium in the blood and urine.
Several animal models have demonstrated hypervitaminosis D–induced aortic and coronary artery calcification. Like with kidney stones, the mechanism appears to be through increased calcium and phosphate levels. Shroff and colleagues studied serum vitamin D levels and vascular disease in children with renal disease on dialysis and found a U-shaped distribution: Children with both low and high vitamin D levels had significantly increased carotid artery intima-media thickness and calcification.5 Given the specialized nature of this population, it’s unclear whether these results can be generalized to most people. More studies are warranted on this topic.
Other benefits
Vitamin D is perhaps most famous for helping to build strong bones. Avenell and colleagues performed a Cochrane meta-analysis of vitamin D supplementation in older adults and found that vitamin D alone did not significantly reduce the risk of hip or other new fracture. Vitamin D plus calcium supplementation did reduce the risk of hip fracture (nine trials, pooled number of individuals was 49,853; relative risk, 0.84; P = .01).6
A lesser-known benefit of vitamin D is muscle protection. A prospective study out of the Jewish Hospital of Cincinnati followed 146 adults who were intolerant to two or more statins because of muscle side effects and found to have a vitamin D level below 32 ng per mL. Subjects were given vitamin D replacement (50,000 units weekly) and followed for 2 years. On statin rechallenge, 88-95% tolerated a statin with vitamin D levels 53-55 ng/mL.7
Pearl
Vitamin D supplementation may protect against COVID-19 infection and has very low chance of harm at daily doses at or below 4,000 IU. Other benefits of taking vitamin D include bone protection and reduction in statin-induced myopathy. The main adverse effect is kidney stones.

Treat obesity like breast cancer, with empathy, say Canadians
A new Canadian clinical practice guideline for treating adults with obesity emphasizes improving health rather than simply losing weight, among other things.
A summary of the guideline, which was developed by Obesity Canada and the Canadian Association of Bariatric Physicians and Surgeons, was published online August 4 in the Canadian Medical Association Journal.
This patient-centered update to the 2006 guidelines is “provocative,” starting with its definition of obesity, co–lead author Sean Wharton, MD, adjunct professor at McMaster University, Hamilton, Ont., said in an interview.
The guideline was authored by more than 60 health care professionals and researchers who assessed more than 500,000 peer-reviewed articles and made 80 key recommendations.
These reflect substantial recent advances in the understanding of obesity. Individuals with obesity (from a patient committee of the Obesity Society) helped to shape the key messages.
“People who live with obesity have been shut out of receiving quality health care because of the biased, deeply flawed misconceptions about what drives obesity and how we can improve health,” Lisa Schaffer, chair of Obesity Canada’s Public Engagement Committee, said in a press release.
“Obesity is widely seen as the result of poor personal decisions, but research tells us it is far more complicated than that. Our hope with the [new] clinical practice guideline is that more health care professionals, health policy makers, benefits providers and people living with obesity will have a better understanding of it, so we can help more of those who need it.”
“Obesity management should be about compassion and empathy, and then everything falls into place,” Dr. Wharton said. “Think of obesity like breast cancer.”
Address the root causes of obesity
The guideline defines obesity as “a prevalent, complex, progressive and relapsing chronic disease, characterized by abnormal or excessive body fat (adiposity) that impairs health.”
Aimed at primary care providers, the document stresses that clinicians need to “move beyond simplistic approaches of ‘eat less, move more,’ and address the root drivers of obesity.”
As a first step, doctors should ask a patient for permission to discuss weight (e.g., they can ask: “Would it be all right if we discussed your weight?”) – which demonstrates empathy and can help build patient-provider trust.
Clinicians can still measure body mass index as part of a routine physical examination, but they should also obtain a comprehensive patient history to identify the root causes of any weight gain (which could include genetics or psychological factors such as depression and anxiety), as well as any barriers to managing obesity.
‘Eat less, move more’ is too simple: Employ three pillars
Advice to “eat less and move more is dangerously simplistic,” coauthor Arya M. Sharma, MD, from the University of Alberta, Edmonton, and scientific director of Obesity Canada, said in an interview that “the body fights to put back any lost weight.”
Patients with obesity need “medical nutrition therapy.” For patients at risk for heart disease, that may mean following a Mediterranean diet, Dr. Wharton said.
“Physical activity and medical nutrition therapy are absolutely necessary” to manage obesity, he clarified. As a person loses weight, their body “releases a cascade of neurochemicals and hormones that try to push the weight back up” to the original weight or even higher.
Therefore, to maintain weight loss, people need support from one or more of what he calls the “three pillars” of effective long-term weight loss – pharmacotherapy, bariatric surgery, and cognitive-behavioral therapy – which tempers this cascade of neurochemicals.
Cognitive-behavioral therapy could be given by various health care professionals, he noted. A behavioral strategy to stop snacking, for example, is to wait 5 minutes before eating a desired snack to make sure you still want it.
Similarly, Dr. Sharma noted, “the reason obesity is a chronic disease is that once you’ve gained the weight, your body is not going to want to lose it. That is what I tell all my patients: ‘Your body doesn’t care why you put on the weight, but it does care about keeping it there, and it’s going to fight you’ when you try to maintain weight loss.”
“Clinicians should feel very comfortable” treating obesity as a chronic disease, he added, because they are already treating chronic diseases such as heart, lung, and kidney disease.
Don’t play the blame game: ‘Think of obesity like breast cancer’
Clinicians also need to avoid “shaming and blaming patients with obesity,” said Dr. Sharma.
He noted that many patients have internalized weight bias and blame their excess weight on their lack of willpower. They may not want to talk about weight-loss medications or bariatric surgery because they feel that’s “cheating.”
By thinking of obesity in a similar way to cancer, doctors can help themselves respond to patients in a kinder way. “What would we do with somebody who has breast cancer? We would have compassion. We would talk about surgery to get the lump out and medication to keep the cancer from coming back, and we would engage them in psychological treatment or counseling for some of the challenges they have to face,” Dr. Wharton said.
“The right answer is to treat [obesity] like a disease – with surgery, medication, and psychological intervention,” depending on the individual patient, he added.
The complete guideline is available on the Obesity Canada website.
The study was funded by Obesity Canada, the Canadian Association of Bariatric Physicians and Surgeons, and the Canadian Institutes of Health Research. Dr. Wharton has received honoraria and travel expenses and has participated in academic advisory boards for Novo Nordisk, Bausch Health, Eli Lilly, and Janssen. He is the medical director of a medical clinic specializing in weight management and diabetes. Dr. Sharma has received speaker’s bureau and consulting fees from Novo Nordisk, Bausch Pharmaceuticals, and AstraZeneca.

Humira topped drug-revenue list for 2019
Humira outsold all other drugs in 2019 in terms of revenue as cytokine inhibitor medications earned their way to three of the first four spots on the pharmaceutical best-seller list, according to a new analysis from the IQVIA Institute for Human Data Science.
Sales of Humira (adalimumab) amounted to $21.4 billion before discounting, Murray Aitken, the institute’s executive director, and associates wrote in their analysis. That’s more than double the total of the anticoagulant Eliquis (apixaban), which brought in $9.9 billion in its last year before generic forms became available.
The next two spots were filled by the tumor necrosis factor inhibitor Enbrel (etanercept) with $8.1 billion in sales and the interleukin 12/23 inhibitor Stelara (ustekinumab) with sales totaling $6.6 billion, followed by the chemotherapy drug Keytruda (pembrolizumab) close behind after racking up $6.5 billion in sales, the researchers reported.
Total nondiscounted spending on all drugs in the U.S. market came to $511 billion in 2019, an increase of 5.7% over the $484 billion spent in 2018, based on data from the July 2020 IQVIA National Sales Perspectives.
These figures are “not adjusted for estimates of off-invoice discounts and rebates,” the authors noted, but they include “prescription and insulin products sold into chain and independent pharmacies, food store pharmacies, mail service pharmacies, long-term care facilities, hospitals, clinics, and other institutional settings.”
Those “discounts and rebates” do exist, however, and they can add up. Drug sales for 2019, “after deducting negotiated rebates, discounts, and other forms of price concessions, such as patient coupons or vouchers that offset out-of-pocket costs,” were $235 billion less than overall nondiscounted spending, the report noted.
Now that we’ve shown you the money, let’s take a quick look at volume. The leading drugs by number of dispensed prescriptions in 2019 were, not surprisingly, quite different. First, with 118 million prescriptions, was atorvastatin, followed by levothyroxine (113 million), lisinopril (96), amlodipine (89), and metoprolol (85), Mr. Aitken and associates reported.
Altogether, over 4.2 billion prescriptions were dispensed last year, with a couple of caveats: 90-day and 30-day fills were both counted as one prescription, and OTC drugs were not included, they pointed out.

NAFLD may predict arrhythmia recurrence post-AFib ablation
Increasingly recognized as an independent risk factor for new-onset atrial fibrillation (AFib), new research suggests for the first time that nonalcoholic fatty liver disease (NAFLD) also confers a higher risk for arrhythmia recurrence after AFib ablation.
Over 29 months of postablation follow-up, 56% of patients with NAFLD suffered bouts of arrhythmia, compared with 31% of patients without NAFLD, matched on the basis of age, sex, body mass index (BMI), ejection fraction within 5%, and AFib type (P < .0001).
The presence of NAFLD was an independent predictor of arrhythmia recurrence in multivariable analyses adjusted for several confounders, including hemoglobin A1c, BMI, and AFib type (hazard ratio, 3.0; 95% confidence interval, 1.94-4.68).
The association is concerning given that one in four adults in the United States has NAFLD, and up to 6.1 million Americans are estimated to have Afib. Previous studies, such as ARREST-AF and LEGACY, however, have demonstrated the benefits of aggressive preablation cardiometabolic risk factor modification on long-term AFib ablation success.
Indeed, none of the NAFLD patients in the present study who lost at least 10% of their body weight had recurrent arrhythmia, compared with 31% who lost less than 10%, and 91% who gained weight prior to ablation (P < .0001).
All 22 patients whose A1c increased during the 12 months prior to ablation had recurrent arrhythmia, compared with 36% of patients whose A1c improved (P < .0001).
“I don’t think the findings of the study were particularly surprising, given what we know. It’s just further reinforcement of the essential role of risk-factor modification,” lead author Eoin Donnellan, MD, Cleveland Clinic, said in an interview.
The results were published Augus 12 in JACC Clinical Electrophysiology.
For the study, the researchers examined data from 267 consecutive patients with a mean BMI of 32.7 kg/m2 who underwent radiofrequency ablation (98%) or cryoablation (2%) at the Cleveland Clinic between January 2013 and December 2017.
All patients were followed for at least 12 months after ablation and had scheduled clinic visits at 3, 6, and 12 months after pulmonary vein isolation, and annually thereafter.
NAFLD was diagnosed in 89 patients prior to ablation on the basis of CT imaging and abdominal ultrasound or MRI. On the basis of NAFLD-Fibrosis Score (NAFLD-FS), 13 patients had a low probability of liver fibrosis (F0-F2), 54 had an indeterminate probability, and 22 a high probability of fibrosis (F3-F4).
Compared with patients with no or early fibrosis (F0-F2), patients with advanced liver fibrosis (F3-F4) had almost a threefold increase in AFib recurrence (82% vs. 31%; P = .003).
“Cardiologists should make an effort to risk-stratify NAFLD patients either by NAFLD-FS or [an] alternative option, such as transient elastography or MR elastography, given these observations, rather than viewing it as either present or absence [sic] and involve expert multidisciplinary team care early in the clinical course of NAFLD patients with evidence of advanced fibrosis,” Dr. Donnellan and colleagues wrote.
Coauthor Thomas G. Cotter, MD, department of gastroenterology and hepatology, University of Chicago, said in an interview that cardiologists could use just the NAFLD-FS as part of an algorithm for an AFib.
“Because if it shows low risk, then it’s very, very likely the patient will be fine,” he said. “To use more advanced noninvasive testing, there are subtleties in the interpretation that would require referral to a liver doctor or a gastroenterologist and the cost of referring might bulk up the costs. But the NAFLD-FS is freely available and is a validated tool.”
Although it hasn’t specifically been validated in patients with AFib, the NAFLD-FS has been shown to correlate with the development of coronary artery disease (CAD) and was recommended for clinical use in U.S. multisociety guidelines for NAFLD.
The score is calculated using six readily available clinical variables (age, BMI, hyperglycemia or diabetes, AST/ALT, platelets, and albumin). It does not include family history or alcohol consumption, which should be carefully detailed given the large overlap between NAFLD and alcohol-related liver disease, Dr. Cotter observed.
Of note, the study excluded patients with alcohol consumption of more than 30 g/day in men and more than 20 g/day in women, chronic viral hepatitis, Wilson’s disease, and hereditary hemochromatosis.
Finally, CT imaging revealed that epicardial fat volume (EFV) was greater in patients with NAFLD than in those without NAFLD (248 vs. 223 mL; P = .01).
Although increased amounts of epicardial fat have been associated with CAD, there was no significant difference in EFV between patients who did and did not develop recurrent arrhythmia (238 vs. 229 mL; P = .5). Nor was EFV associated with arrhythmia recurrence on Cox proportional hazards analysis (HR, 1.001; P = .17).
“We hypothesized that the increased risk of arrhythmia recurrence may be mediated in part by an increased epicardial fat volume,” Dr. Donnellan said. “The existing literature exploring the link between epicardial fat volume and A[Fib] burden and recurrence is conflicting. But in both this study and our bariatric surgery study, epicardial fat volume was not a significant predictor of arrhythmia recurrence on multivariable analysis.”
It’s likely that the increased recurrence risk is caused by several mechanisms, including NAFLD’s deleterious impact on cardiac structure and function, the bidirectional relationship between NAFLD and sleep apnea, and transcription of proinflammatory cytokines and low-grade systemic inflammation, he suggested.
“Patients with NAFLD represent a particularly high-risk population for arrhythmia recurrence. NAFLD is a reversible disease, and a multidisciplinary approach incorporating dietary and lifestyle interventions should by instituted prior to ablation,” Dr. Donnellan and colleagues concluded.
They noted that serial abdominal imaging to assess for preablation changes in NAFLD was limited in patients and that only 56% of control subjects underwent dedicated abdominal imaging to rule out hepatic steatosis. Also, the heterogeneity of imaging modalities used to diagnose NAFLD may have influenced the results and the study’s single-center, retrospective design limits their generalizability.
The authors reported having no relevant financial relationships.

“Cardiologists should make an effort to risk-stratify NAFLD patients either by NAFLD-FS or [an] alternative option, such as transient elastography or MR elastography, given these observations, rather than viewing it as either present or absence [sic] and involve expert multidisciplinary team care early in the clinical course of NAFLD patients with evidence of advanced fibrosis,” Dr. Donnellan and colleagues wrote.
Coauthor Thomas G. Cotter, MD, department of gastroenterology and hepatology, University of Chicago, said in an interview that cardiologists could use just the NAFLD-FS as part of an algorithm for an AFib.
“Because if it shows low risk, then it’s very, very likely the patient will be fine,” he said. “To use more advanced noninvasive testing, there are subtleties in the interpretation that would require referral to a liver doctor or a gastroenterologist and the cost of referring might bulk up the costs. But the NAFLD-FS is freely available and is a validated tool.”
Although it hasn’t specifically been validated in patients with AFib, the NAFLD-FS has been shown to correlate with the development of coronary artery disease (CAD) and was recommended for clinical use in U.S. multisociety guidelines for NAFLD.
The score is calculated using six readily available clinical variables (age, BMI, hyperglycemia or diabetes, AST/ALT, platelets, and albumin). It does not include family history or alcohol consumption, which should be carefully detailed given the large overlap between NAFLD and alcohol-related liver disease, Dr. Cotter observed.
Of note, the study excluded patients with alcohol consumption of more than 30 g/day in men and more than 20 g/day in women, chronic viral hepatitis, Wilson’s disease, and hereditary hemochromatosis.
Finally, CT imaging revealed that epicardial fat volume (EFV) was greater in patients with NAFLD than in those without NAFLD (248 vs. 223 mL; P = .01).
Although increased amounts of epicardial fat have been associated with CAD, there was no significant difference in EFV between patients who did and did not develop recurrent arrhythmia (238 vs. 229 mL; P = .5). Nor was EFV associated with arrhythmia recurrence on Cox proportional hazards analysis (HR, 1.001; P = .17).
“We hypothesized that the increased risk of arrhythmia recurrence may be mediated in part by an increased epicardial fat volume,” Dr. Donnellan said. “The existing literature exploring the link between epicardial fat volume and A[Fib] burden and recurrence is conflicting. But in both this study and our bariatric surgery study, epicardial fat volume was not a significant predictor of arrhythmia recurrence on multivariable analysis.”
It’s likely that the increased recurrence risk is caused by several mechanisms, including NAFLD’s deleterious impact on cardiac structure and function, the bidirectional relationship between NAFLD and sleep apnea, and transcription of proinflammatory cytokines and low-grade systemic inflammation, he suggested.
“Patients with NAFLD represent a particularly high-risk population for arrhythmia recurrence. NAFLD is a reversible disease, and a multidisciplinary approach incorporating dietary and lifestyle interventions should by instituted prior to ablation,” Dr. Donnellan and colleagues concluded.
They noted that serial abdominal imaging to assess for preablation changes in NAFLD was limited in patients and that only 56% of control subjects underwent dedicated abdominal imaging to rule out hepatic steatosis. Also, the heterogeneity of imaging modalities used to diagnose NAFLD may have influenced the results and the study’s single-center, retrospective design limits their generalizability.
The authors reported having no relevant financial relationships.

Increasingly recognized as an independent risk factor for new-onset atrial fibrillation (AFib), new research suggests for the first time that nonalcoholic fatty liver disease (NAFLD) also confers a higher risk for arrhythmia recurrence after AFib ablation.
Over 29 months of postablation follow-up, 56% of patients with NAFLD suffered bouts of arrhythmia, compared with 31% of patients without NAFLD, matched on the basis of age, sex, body mass index (BMI), ejection fraction within 5%, and AFib type (P < .0001).
The presence of NAFLD was an independent predictor of arrhythmia recurrence in multivariable analyses adjusted for several confounders, including hemoglobin A1c, BMI, and AFib type (hazard ratio, 3.0; 95% confidence interval, 1.94-4.68).
The association is concerning given that one in four adults in the United States has NAFLD, and up to 6.1 million Americans are estimated to have Afib. Previous studies, such as ARREST-AF and LEGACY, however, have demonstrated the benefits of aggressive preablation cardiometabolic risk factor modification on long-term AFib ablation success.
Indeed, none of the NAFLD patients in the present study who lost at least 10% of their body weight had recurrent arrhythmia, compared with 31% who lost less than 10%, and 91% who gained weight prior to ablation (P < .0001).
All 22 patients whose A1c increased during the 12 months prior to ablation had recurrent arrhythmia, compared with 36% of patients whose A1c improved (P < .0001).
“I don’t think the findings of the study were particularly surprising, given what we know. It’s just further reinforcement of the essential role of risk-factor modification,” lead author Eoin Donnellan, MD, Cleveland Clinic, said in an interview.
The results were published Augus 12 in JACC Clinical Electrophysiology.
For the study, the researchers examined data from 267 consecutive patients with a mean BMI of 32.7 kg/m2 who underwent radiofrequency ablation (98%) or cryoablation (2%) at the Cleveland Clinic between January 2013 and December 2017.
All patients were followed for at least 12 months after ablation and had scheduled clinic visits at 3, 6, and 12 months after pulmonary vein isolation, and annually thereafter.
NAFLD was diagnosed in 89 patients prior to ablation on the basis of CT imaging and abdominal ultrasound or MRI. On the basis of NAFLD-Fibrosis Score (NAFLD-FS), 13 patients had a low probability of liver fibrosis (F0-F2), 54 had an indeterminate probability, and 22 a high probability of fibrosis (F3-F4).
Compared with patients with no or early fibrosis (F0-F2), patients with advanced liver fibrosis (F3-F4) had almost a threefold increase in AFib recurrence (82% vs. 31%; P = .003).

AHA statement recommends dietary screening at routine checkups
A new scientific statement from the American Heart Association recommends incorporating a rapid diet-screening tool into routine primary care visits to inform dietary counseling and integrating the tool into patients’ electronic health record platforms across all healthcare settings.
The statement authors evaluated 15 existing screening tools and, although they did not recommend a specific tool, they did present advantages and disadvantages of some of the tools and encouraged “critical conversations” among clinicians and other specialists to arrive at a tool that would be most appropriate for use in a particular health care setting.
“The key takeaway is for clinicians to incorporate discussion of dietary patterns into routine preventive care appointments because a suboptimal diet is the No. 1 risk factor for cardiovascular disease,” Maya Vadiveloo, PhD, RD, chair of the statement group, said in an interview.
“We also wanted to touch on the fact the screening tool could be incorporated into the EHR and then used for clinical support and for tracking and monitoring the patient’s dietary patterns over time,” said Dr. Vadiveloo, assistant professor of nutrition and food sciences in the College of Health Science, University of Rhode Island, Kingston.
The statement was published online Aug. 7 in Circulation: Cardiovascular Quality and Outcomes.
Competing demands
Poor dietary quality has “surpassed all other mortality risk factors, accounting for 11 million deaths and about 50% of cardiovascular disease (CVD) deaths globally,” the authors wrote.
Diets deficient in fruits, vegetables, and whole grains and high in red and processed meat, added sugars, sodium, and total energy are the “leading determinants” of the risks for CVD and other conditions, so “strategies that promote holistically healthier dietary patterns to reduce chronic disease risk are of contemporary importance.”
Most clinicians and other members of health care teams “do not currently assess or counsel patients about their food and beverage intake during routine clinical care,” the authors observed.
Reasons for this may include lack of training and knowledge, insufficient time, insufficient integration of nutrition services into health care settings, insufficient reimbursement, and “competing demands during the visit,” they noted.
Dr. Vadiveloo said that an evidence-based rapid screening tool can go a long way toward helping to overcome these barriers.
“Research shows that when primary care practitioners discuss diet with patients, the patients are receptive, but we also know that clinical workloads are already very compressed, and adding another thing to a routine preventive care appointment is challenging,” she said. “So we wanted to look and see if there were already screening tools that showed promise as valid, reliable, reflective of the best science, and easy to incorporate into various types of practice settings.”
Top picks
The authors established “theoretical and practice-based criteria” for an optimal diet screening tool for use in the adult population (aged 20 to 75 years). The tool had to:
- Be developed or used within clinical practice in the past 10 years.
- Be evidence-based, reliable, and valid.
- Assess total dietary pattern rather than focusing on a single food or nutrient.
- Be able to be completed and scored at administration without special knowledge or software.
- Give actionable next steps and support to patients.
- Be able track and monitor dietary change over time.
- Be brief.
- Be useful for chronic disease management.
Of the 15 tools reviewed, the three that met the most theoretical and practice-based validity criteria were the Mediterranean Diet Adherence Screener (MEDAS) and its variations; the modified, shortened Rapid Eating Assessment for Participants (REAP), and the modified version of the Starting the Conversation Tool. However, the authors noted that the Powell and Greenberg Screening Tool was the “least time-intensive.”
One size does not fit all
No single tool will be appropriate for all practice settings, so “we would like clinicians to discuss what will work in their particular setting,” Dr. Vadiveloo emphasized.
For example, should the screening tool be completed by the clinician, a member of the health care team, or the patient? Advantages of a tool completed by clinicians or team members include collection of the information in real time, where it can be used in shared decision-making during the encounter and increased reliability because the screen has been completed by a clinician. On the other hand, the clinician might not be able to prioritize administering the screening tool during a short clinical encounter.
Advantages of a tool completed by the patient via an EHR portal is that the patient may feel less risk of judgment by the clinician or health care professional and patients can complete the screen at their convenience. Disadvantages are limited reach into underserved populations and, potentially, less reliability than clinician-administered tools.
“It is advantageous to have tools that can be administered by multiple members of health care teams to ease the demand on clinicians, if such staff is available, but in other settings, self-administration might be better, so we tried to leave it open-ended,” Dr. Vadiveloo explained.
‘Ideal platform’
“The EHR is the ideal platform to prompt clinicians and other members of the health care team to capture dietary data and deliver dietary advice to patients,” the authors observed.
EHRs allow secure storage of data and also enable access to these data when needed at the point of care. They are also important for documentation purposes.
The authors noted that the use of “myriad EHR platforms and versions of platforms” have created “technical challenges.” They recommended “standardized approaches” for transmitting health data that will “more seamlessly allow rapid diet screeners to be implemented in the EHR.”
They also recommended that the prototypes of rapid diet screeners be tested by end users prior to implementation within particular clinics. “Gathering these data ahead of time can improve the uptake of the application in the real world,” they stated.
Dr. Vadiveloo added that dietary counseling can be conducted by several members of a health care team, such as a dietitian, not just by the physician. Or the patient may need to be referred to a dietitian for counseling and follow-up.
The authors concluded by characterizing the AHA statement as “a call to action ... designed to accelerate efforts to make diet quality assessment an integral part of office-based care delivery by encouraging critical conversations among clinicians, individuals with diet/lifestyle expertise, and specialists in information technology.”
Dr. Vadiveloo has disclosed no relevant financial relationships. The other authors’ disclosures are listed in the original paper.

Unexpected rosuvastatin-canagliflozin adverse effect reported
A 76-year-old woman presented recently to a Toronto-area hospital with acute onset muscle pain, limb weakness, difficulty walking, and rhabdomyolysis associated with a sharp spike in her plasma level of rosuvastatin – a drug she had been on uneventfully for more than 5 years, within days of starting for the first time treatment with the SGLT2 inhibitor canagliflozin (Invokana).
The patient’s Canadian clinicians stopped her treatment with both rosuvastatin and canagliflozin, administered intravenous crystalloid fluids, and within days her pain subsided and her limb weakness gradually improved, allowing her discharge 10 days later while she was ambulating with a walker.
“To our knowledge this is the first published report of a drug interaction between rosuvastatin and canagliflozin,” wrote the authors of the case report (Ann Intern Med. 2020 Aug 3. doi: 10.7326/L20-0549). They cited the importance of the observation given the widespread use today of rosuvastatin for lowering low density lipoprotein cholesterol and exerting pleiotropic effects; and canagliflozin for its modest effects for reducing hyperglycemia, as well as its important role in reducing adverse cardiovascular outcomes, slowing progression of chronic kidney disease, and having a mild but important diuretic effect. “We encourage clinicians to remain vigilant for features of myotoxicity when canagliflozin and rosuvastatin are coprescribed,” they wrote, avoiding discussion of whether this may represent class or drug-specific effects.
“It’s reasonable to be mindful of this risk, but this is not a reason to not use rosuvastatin and canagliflozin in a patient,” nor for the time being to avoid any other combination of a statin and SGLT2 (sodium-glucose cotransporter 2) inhibitor, said David Juurlink, MD, head of the division of clinical pharmacology and toxicology at Sunnybrook Health Sciences Centre in Toronto and lead author of the report. “Few drug interactions have absolute contraindications. The admonition is just to be careful. It’s premature to say they shouldn’t be used together,” he said in an interview.
“We don’t know how much of an outlier this patient is. But it would be important to tell patients” on this or a similar combination to alert their clinicians if they start to have muscle aches, which should be a “red flag” to stop the statin, the SGLT2 inhibitor, or both until the situation can be fully assessed, Dr. Juurlink advised.
Sky high rosuvastatin levels
The linchpin of the observed adverse effects appeared to be a startlingly high elevation of the patient’s plasma rosuvastatin level when she was hospitalized 15 days after starting canagliflozin and 12 days after the onset of her thigh pain and weakness. Testing showed a plasma rosuvastatin concentration of 176 ng/mL, “more than 15-fold higher than the mean value expected” in patients taking 40 mg rosuvastatin daily, the maximum labeled dosage for the drug and what the affected patient had been taking without prior incident for more than 5 years. The patient’s canagliflozin dosage was 100 mg/day, the standard starting dosage according to the drug’s label.
The report’s authors noted that genetic assessment of the patient, a woman originally from the Philippines who was “high functioning,” and diagnosed with type 2 diabetes, showed she was heterozygous for a polymorphism, c.421C>A, which is linked with increased rosuvastatin plasma levels in the plasma. They also cited a report that canagliflozin can interact with proteins involved in hepatic drug uptake.
“We speculate that, in our patient, the addition of canagliflozin enhanced intestinal rosuvastatin absorption, inhibited its hepatocellular uptake, and impaired its excretion into bile canaliculi and the proximal tubule, resulting in rosuvastatin accumulation and leading to hepatotoxicity and myotoxicity,” the clinicians wrote in their report.
“There is little doubt this was a drug interaction, but it does not apply uniformly to everyone.” The severity of the interaction would depend on the dosages, the comorbidities a patient has, and their genetic profile, Dr. Juurlink said.
Concern and skepticism
Other clinicians who regularly prescribe these drugs expressed concern about the observation as well as skepticism about the prevalence of patients who could potentially experience similar effects.
“We don’t know how common are these genetic abnormalities. If this is extremely rare, then it doesn’t have many clinical implications, but if a large portion of the population has this [genetic] abnormality, it’s something we’d need to pay attention to,” Steven E. Nissen, MD, chair of cardiovascular medicine at the Cleveland Clinic Foundation, said in an interview. “It will be important to know the prevalence” of the genetic polymorphism carried by the reported patient, said Dr. Nissen, who has done research on lipid-lowering medications and drug safety.
“This could be important, or a very rare one-off. I can’t say which,” based on what’s currently known, he said. “There are many unanswered questions that make it hard to know how important this will be. It requires further investigation. There is a lot of uncertainty.”
Dr. Nissen particularly endorsed studies that approach this issue by looking at the prevalence rates of the implicated genetic polymorphism rather than pharmacovigilance studies that make epidemiologic assessments of adverse-effect prevalence. Studies that look for adverse-effect associations in large patient populations are “sloppy, and unless the interaction is incredibly intense they are not very sensitive,” he said.
But Dr. Juurlink, a pharmacoepidemiologist whose specialty includes studies of this sort, said that they could be useful if carefully designed. He suggested, for example, comparing in large patient databases the observed incidence of rhabdomyolysis among patients on an SGLT2 inhibitor and also on rosuvastatin with those on pravastatin, a statin with a different metabolic profile. Another approach to further examining the observation would be dosage studies with rosuvastatin and canagliflozin in healthy volunteers, he said.
Dr. Nissen noted that rosuvastatin is a key agent from the statin class because it’s the “most effective” for lowering low density lipoprotein cholesterol. “Rosuvastatin is a go-to drug,” he declared. On the other hand, canagliflozin is “a little less used” than other drugs in the SGLT2 inhibitor class, specifically dapagliflozin (Farxiga) and empagliflozin (Jardiance), he said.
One in a million?
“This was a freak accident. I don’t find it at all concerning. It was definitely one in a million,” Yehuda Handelsman, MD, an endocrinologist and diabetes specialist who is medical director of The Metabolic Institute of America in Tarzana, Calif., said in an interview. “None of us have seen it” in either the several cardiovascular outcome trials now run on multiple drugs in the SGLT2 inhibitor class that included many patients also taking a statin, or in routine practice, he said. Dr. Handelsman noted that in his practice he had never seen a similar case despite treating “hundreds if not thousands of patients” with type 2 diabetes, virtually all of whom were on a statin and were also treated with an SGLT2 inhibitor, including many with canagliflozin.
Dr. Handelsman cited the notably low estimated glomerular filtration rate in the reported patient, who was described as having a serum creatinine level of 150 mcmol/L (1.7 mg/dL) prior to canagliflozin treatment that then rose to 194 mcmol/L (2.19 mg/dL) at the time of hospitalization, which corresponds to estimated glomerular filtration rates of 29-31 and 21-23 mL/min per 1.73 m2, respectively, depending on the calculator used, rates that were possibly below the labeled minimum rate of 30 mL/min per 1.73 m2 for patients starting canagliflozin treatment. The case report cited the patient as having stage 3B chronic kidney disease, which corresponds to a eGFR of 30-44* mL/min per 1.73 m2.
“I think the patient had acute kidney injury” on starting canagliflozin “that may have affected the [rosuvastatin] metabolism,” Dr. Handelsman suggested. “She had severe kidney dysfunction to start with that fell further with SGLT2 inhibitor treatment,” a well described and usually transient effect of starting drugs in this class because of changes the SGLT2 inhibitors cause in renal blood flow. He noted that the patient had not been receiving an angiotensin-converting enzyme inhibitor or angiotensin-receptor blocker, which may have contributed to her acute problems with fluid balance. Most similar patients with type 2 diabetes, cardiovascular disease risk, and chronic kidney disease would be on stable treatment with a drug that inhibits the renin-angiotensin system before starting an SGLT2 inhibitor, and not already having a RAS inhibitor on board before starting canagliflozin may have somehow contributed to the observed adverse effects, Dr. Handelsman said.
Dr. Juurlink was skeptical that the kidneys played a major role. “An abrupt change in renal function can influence statin clearance, but this was a 15-fold increase. You can’t explain such a dramatic increase by a transient reduction in renal function,” he said.
Dr. Juurlink and coauthors had no disclosures. Dr. Nissen had no relevant disclosures. Dr. Handelsman has been a consultant to companies that market drugs in the SGLT2 inhibitor class.

A 76-year-old woman presented recently to a Toronto-area hospital with acute onset muscle pain, limb weakness, difficulty walking, and rhabdomyolysis associated with a sharp spike in her plasma level of rosuvastatin – a drug she had been on uneventfully for more than 5 years, within days of starting for the first time treatment with the SGLT2 inhibitor canagliflozin (Invokana).
The patient’s Canadian clinicians stopped her treatment with both rosuvastatin and canagliflozin, administered intravenous crystalloid fluids, and within days her pain subsided and her limb weakness gradually improved, allowing her discharge 10 days later while she was ambulating with a walker.
“To our knowledge this is the first published report of a drug interaction between rosuvastatin and canagliflozin,” wrote the authors of the case report (Ann Intern Med. 2020 Aug 3. doi: 10.7326/L20-0549). They cited the importance of the observation given the widespread use today of rosuvastatin for lowering low density lipoprotein cholesterol and exerting pleiotropic effects; and canagliflozin for its modest effects for reducing hyperglycemia, as well as its important role in reducing adverse cardiovascular outcomes, slowing progression of chronic kidney disease, and having a mild but important diuretic effect. “We encourage clinicians to remain vigilant for features of myotoxicity when canagliflozin and rosuvastatin are coprescribed,” they wrote, avoiding discussion of whether this may represent class or drug-specific effects.
“It’s reasonable to be mindful of this risk, but this is not a reason to not use rosuvastatin and canagliflozin in a patient,” nor for the time being to avoid any other combination of a statin and SGLT2 (sodium-glucose cotransporter 2) inhibitor, said David Juurlink, MD, head of the division of clinical pharmacology and toxicology at Sunnybrook Health Sciences Centre in Toronto and lead author of the report. “Few drug interactions have absolute contraindications. The admonition is just to be careful. It’s premature to say they shouldn’t be used together,” he said in an interview.
“We don’t know how much of an outlier this patient is. But it would be important to tell patients” on this or a similar combination to alert their clinicians if they start to have muscle aches, which should be a “red flag” to stop the statin, the SGLT2 inhibitor, or both until the situation can be fully assessed, Dr. Juurlink advised.
Sky high rosuvastatin levels
The linchpin of the observed adverse effects appeared to be a startlingly high elevation of the patient’s plasma rosuvastatin level when she was hospitalized 15 days after starting canagliflozin and 12 days after the onset of her thigh pain and weakness. Testing showed a plasma rosuvastatin concentration of 176 ng/mL, “more than 15-fold higher than the mean value expected” in patients taking 40 mg rosuvastatin daily, the maximum labeled dosage for the drug and what the affected patient had been taking without prior incident for more than 5 years. The patient’s canagliflozin dosage was 100 mg/day, the standard starting dosage according to the drug’s label.
The report’s authors noted that genetic assessment of the patient, a woman originally from the Philippines who was “high functioning,” and diagnosed with type 2 diabetes, showed she was heterozygous for a polymorphism, c.421C>A, which is linked with increased rosuvastatin plasma levels in the plasma. They also cited a report that canagliflozin can interact with proteins involved in hepatic drug uptake.
“We speculate that, in our patient, the addition of canagliflozin enhanced intestinal rosuvastatin absorption, inhibited its hepatocellular uptake, and impaired its excretion into bile canaliculi and the proximal tubule, resulting in rosuvastatin accumulation and leading to hepatotoxicity and myotoxicity,” the clinicians wrote in their report.
“There is little doubt this was a drug interaction, but it does not apply uniformly to everyone.” The severity of the interaction would depend on the dosages, the comorbidities a patient has, and their genetic profile, Dr. Juurlink said.
Concern and skepticism
Other clinicians who regularly prescribe these drugs expressed concern about the observation as well as skepticism about the prevalence of patients who could potentially experience similar effects.
“We don’t know how common are these genetic abnormalities. If this is extremely rare, then it doesn’t have many clinical implications, but if a large portion of the population has this [genetic] abnormality, it’s something we’d need to pay attention to,” Steven E. Nissen, MD, chair of cardiovascular medicine at the Cleveland Clinic Foundation, said in an interview. “It will be important to know the prevalence” of the genetic polymorphism carried by the reported patient, said Dr. Nissen, who has done research on lipid-lowering medications and drug safety.
“This could be important, or a very rare one-off. I can’t say which,” based on what’s currently known, he said. “There are many unanswered questions that make it hard to know how important this will be. It requires further investigation. There is a lot of uncertainty.”
Dr. Nissen particularly endorsed studies that approach this issue by looking at the prevalence rates of the implicated genetic polymorphism rather than pharmacovigilance studies that make epidemiologic assessments of adverse-effect prevalence. Studies that look for adverse-effect associations in large patient populations are “sloppy, and unless the interaction is incredibly intense they are not very sensitive,” he said.
But Dr. Juurlink, a pharmacoepidemiologist whose specialty includes studies of this sort, said that they could be useful if carefully designed. He suggested, for example, comparing in large patient databases the observed incidence of rhabdomyolysis among patients on an SGLT2 inhibitor and also on rosuvastatin with those on pravastatin, a statin with a different metabolic profile. Another approach to further examining the observation would be dosage studies with rosuvastatin and canagliflozin in healthy volunteers, he said.
Dr. Nissen noted that rosuvastatin is a key agent from the statin class because it’s the “most effective” for lowering low density lipoprotein cholesterol. “Rosuvastatin is a go-to drug,” he declared. On the other hand, canagliflozin is “a little less used” than other drugs in the SGLT2 inhibitor class, specifically dapagliflozin (Farxiga) and empagliflozin (Jardiance), he said.
One in a million?

FROM ANNALS OF INTERNAL MEDICINE
Most younger MI patients wouldn’t get statins under guidelines
Clinical guidelines for cholesterol management may have two blind spots when it comes to heart attack prevention: Most younger adults with premature coronary artery disease who’ve had a myocardial infarction don’t meet guideline criteria for preventative statin therapy, and survivors under age 55 don’t meet the criteria for continuing nonstatin lipid-lowering treatments, a large single-center retrospective study has shown.
“The classic approach we’ve taken to identifying young adults for prevention is inadequate in younger adults,” corresponding author Ann Marie Navar, MD, PhD, of Duke University, Durham, N.C., said in an interview. “While awaiting more definitive research we should at minimum be using all the tools at our disposal, including broader use of coronary artery calcium [CAC] scoring, to identify young people who may benefit from statin therapy.”
The retrospective observational study analyzed records of 6,639 adults who had cardiac catheterization at Duke University Medical Center from 1995 to 2012 for a first myocardial infarction with obstructive coronary artery disease. The study considered those under age 55 years as “younger” patients, comprising 41% of the study group (2,733); 35% were “middle-aged” at 55-65 years (2,324) and 24% were “older,” at 66-75 years (1,582).
The report, published online Aug. 3 in the Journal of the American College of Cardiology, noted that most of the adults with premature CAD did not meet criteria for preventative statin therapy before their first MI based on ACC/American Heart Association clinical guidelines from 2013 and 2018. It also noted that younger MI survivors are also less frequently eligible for secondary prevention with intensive nonstatin lipid-lowering therapies than are older adults despite a much longer potential life span – and opportunity for another MI – for the former.
The researchers sought to evaluate the real-world implications of changes made in the 2018 guideline for adults who develop premature ischemic heart disease, and found that fewer younger patients qualify for preventative statin therapy under the 2018 guidelines.
“Younger individuals with very high-risk criteria are at higher risk of major adverse cardiovascular events, a finding supporting the appropriate implementation of intensive lipid-lowering therapies in these patients,” wrote lead author Michel Zeitouni, MD, MSc, and colleagues.
Key findings
The investigators reported that younger adults were significantly less likely to meet a class I recommendation for statins under the 2013 guideline (42.9%), compared with their middle-aged (70%) and older (82.5%) counterparts; and under the 2018 guideline, at 39.4%, 59.5%, and 77.4%, respectively (both P < .001).
Similarly, when both class I and class IIa recommendations were accounted for, younger patients were significantly less likely than were middle-aged and older patients to be eligible for statins before their index MI under both the 2013 (56.7%, 79.5%, and 85.2%, respectively and 2018 guidelines (46.4%, 73.5%, and 88.2%, respectively (both P < .01).
After their first MI, one in four younger patients (28.3%) met the very high-risk criteria compared with 40% of middle-aged and 81.4% of older patients (P trend < .001). In 8 years of follow-up, patients with very high-risk criteria based on the 2018 guideline had twice the rate of death, nonfatal MI, or stroke (hazard ratio [HR]: 2.15; 95% confidence interval, 1.98-2.33; P < .001).
The researchers acknowledged that the 2018 guideline took the important step of implementing risk enhancers – patient characteristics such as obesity and metabolic syndrome – along with the 10-year atherosclerotic cardiovascular disease (ASCVD) risk score to better identify high-risk young individuals who need statins. However, they also noted that the ability of the guidelines to identify young adults before their first MI “remains suboptimal.”
How to protect younger patients
“The 2018 guidelines will be most effective if we as providers do our best to identify risk enhancers and if we can use CAC scoring more broadly,” Dr. Navar said, noting that although CAC scoring has been shown to improve risk prediction, insurance coverage can be problematic.
“We also need to be careful to screen for the presence of the risk enhancers, such as inflammatory disease, family history, and women-specific risk factors, to make sure we aren’t missing an important high-risk group,” she added.
Other solutions to better identify at-risk younger adults include considering upgrades to the guidelines’ class IIb recommendation to class IIa to emphasize the importance of recognizing lower-risk younger adults, and recommending statins for patients at higher lifetime risk than age- and sex-matched peers, the researchers noted. “In our cohort, young individuals admitted for a first MI had a higher lifetime ASCVD risk score than did patients in the older age categories,” Dr. Zeitouni and colleagues wrote.
Dr. Navar said that these findings are a reminder that guidelines aren’t mandates. “Guidelines are meant to be a starting point for patients and physicians,” she said. “The absence of a recommendation doesn’t mean something isn’t recommended, but that there is not enough data to say one way or another.”
The study “provides important evidence” that the 2018 guidelines exempted about half of the younger adults who had a first MI from preventative statin therapy, Ron Blankstein, MD, and Avinainder Singh, MD, MMSc, noted in an editorial (J Am Coll Cardiol. 2020;76:665-8).
“Data from both the Duke and Young-MI registries should force us to reexamine how we allocate statin use among young individuals,” they noted. Dr. Blankstein is with Brigham and Women’s Hospital, Harvard Medical School, Boston. Dr. Singh is with Yale University, New Haven, Conn.

Clinical guidelines for cholesterol management may have two blind spots when it comes to heart attack prevention: Most younger adults with premature coronary artery disease who’ve had a myocardial infarction don’t meet guideline criteria for preventative statin therapy, and survivors under age 55 don’t meet the criteria for continuing nonstatin lipid-lowering treatments, a large single-center retrospective study has shown.
“The classic approach we’ve taken to identifying young adults for prevention is inadequate in younger adults,” corresponding author Ann Marie Navar, MD, PhD, of Duke University, Durham, N.C., said in an interview. “While awaiting more definitive research we should at minimum be using all the tools at our disposal, including broader use of coronary artery calcium [CAC] scoring, to identify young people who may benefit from statin therapy.”
The retrospective observational study analyzed records of 6,639 adults who had cardiac catheterization at Duke University Medical Center from 1995 to 2012 for a first myocardial infarction with obstructive coronary artery disease. The study considered those under age 55 years as “younger” patients, comprising 41% of the study group (2,733); 35% were “middle-aged” at 55-65 years (2,324) and 24% were “older,” at 66-75 years (1,582).
The report, published online Aug. 3 in the Journal of the American College of Cardiology, noted that most of the adults with premature CAD did not meet criteria for preventative statin therapy before their first MI based on ACC/American Heart Association clinical guidelines from 2013 and 2018. It also noted that younger MI survivors are also less frequently eligible for secondary prevention with intensive nonstatin lipid-lowering therapies than are older adults despite a much longer potential life span – and opportunity for another MI – for the former.
The researchers sought to evaluate the real-world implications of changes made in the 2018 guideline for adults who develop premature ischemic heart disease, and found that fewer younger patients qualify for preventative statin therapy under the 2018 guidelines.
“Younger individuals with very high-risk criteria are at higher risk of major adverse cardiovascular events, a finding supporting the appropriate implementation of intensive lipid-lowering therapies in these patients,” wrote lead author Michel Zeitouni, MD, MSc, and colleagues.
Key findings
The investigators reported that younger adults were significantly less likely to meet a class I recommendation for statins under the 2013 guideline (42.9%), compared with their middle-aged (70%) and older (82.5%) counterparts; and under the 2018 guideline, at 39.4%, 59.5%, and 77.4%, respectively (both P < .001).
Similarly, when both class I and class IIa recommendations were accounted for, younger patients were significantly less likely than were middle-aged and older patients to be eligible for statins before their index MI under both the 2013 (56.7%, 79.5%, and 85.2%, respectively and 2018 guidelines (46.4%, 73.5%, and 88.2%, respectively (both P < .01).
After their first MI, one in four younger patients (28.3%) met the very high-risk criteria compared with 40% of middle-aged and 81.4% of older patients (P trend < .001). In 8 years of follow-up, patients with very high-risk criteria based on the 2018 guideline had twice the rate of death, nonfatal MI, or stroke (hazard ratio [HR]: 2.15; 95% confidence interval, 1.98-2.33; P < .001).
The researchers acknowledged that the 2018 guideline took the important step of implementing risk enhancers – patient characteristics such as obesity and metabolic syndrome – along with the 10-year atherosclerotic cardiovascular disease (ASCVD) risk score to better identify high-risk young individuals who need statins. However, they also noted that the ability of the guidelines to identify young adults before their first MI “remains suboptimal.”
How to protect younger patients
“The 2018 guidelines will be most effective if we as providers do our best to identify risk enhancers and if we can use CAC scoring more broadly,” Dr. Navar said, noting that although CAC scoring has been shown to improve risk prediction, insurance coverage can be problematic.
“We also need to be careful to screen for the presence of the risk enhancers, such as inflammatory disease, family history, and women-specific risk factors, to make sure we aren’t missing an important high-risk group,” she added.
Other solutions to better identify at-risk younger adults include considering upgrades to the guidelines’ class IIb recommendation to class IIa to emphasize the importance of recognizing lower-risk younger adults, and recommending statins for patients at higher lifetime risk than age- and sex-matched peers, the researchers noted. “In our cohort, young individuals admitted for a first MI had a higher lifetime ASCVD risk score than did patients in the older age categories,” Dr. Zeitouni and colleagues wrote.
Dr. Navar said that these findings are a reminder that guidelines aren’t mandates. “Guidelines are meant to be a starting point for patients and physicians,” she said. “The absence of a recommendation doesn’t mean something isn’t recommended, but that there is not enough data to say one way or another.”
The study “provides important evidence” that the 2018 guidelines exempted about half of the younger adults who had a first MI from preventative statin therapy, Ron Blankstein, MD, and Avinainder Singh, MD, MMSc, noted in an editorial (J Am Coll Cardiol. 2020;76:665-8).
“Data from both the Duke and Young-MI registries should force us to reexamine how we allocate statin use among young individuals,” they noted. Dr. Blankstein is with Brigham and Women’s Hospital, Harvard Medical School, Boston. Dr. Singh is with Yale University, New Haven, Conn.

AHA statement addresses genetic testing for CVD
A new scientific statement from the American Heart Association recommends that genetic testing for inherited cardiovascular disease should be reserved for four specific types of heart diseases – cardiomyopathies, thoracic aortic aneurysms and dissections, arrhythmias, and familial hypercholesterolemia – and should enlist skilled geneticists and genetic counselors in the care team.
The guidance comes in a scientific statement published online in the journal Circulation: Genomic and Precision Medicine.
Kiran Musunuru, MD, PhD, MPH, ML, chair of the writing group for the scientific statement, described in an interview the rationale for publishing the statement at this time. “There was no prior single statement that summarized best practices for the whole gamut of inherited cardiovascular diseases in adults, only statements for individual diseases,” he said in an interview. “With genetic testing seeing explosive growth in the past few years, both in the clinical setting and with direct-to-consumer testing, we felt that cardiovascular practitioners would benefit from having a single document to serve as a general resource on genetic testing.”
The statement describes two types of patients who would be suitable for genetic testing for cardiovascular disease (CVD), Dr. Musunuru noted: “Patients who have been diagnosed with or are strongly suspected to have a cardiovascular disease that is often inherited and family members of patients who have been diagnosed with an inherited cardiovascular disease and found by genetic testing to have a mutation that is felt to be the cause of the disease.”
The statement also spells out two crucial elements for genetic testing: thorough disease-specific phenotyping – that is, using genetic information to identify the individual’s disease characteristics and a comprehensive family history that spans at least three generations. Testing should only proceed after patients has had genetic counseling and made a shared decision with their doctors.
“Genetic counseling is absolutely essential both before genetic testing to educate patients on what genetic testing entails and what potential results to expect, as well as the risks of testing; and after genetic testing, to review the results of the genetic testing and explain the potential consequences for the patient’s health and the health of family members, including children,” Dr. Musunuru said.
The process should involve board-certified geneticists or at least cardiovascular specialists well-versed in genetics and genetic counselors, the statement noted. The latter are “critical” in the care team, Dr. Musunuru said.
After the decision is made to do genetic testing, the next step is to decide the scope of the testing. That can range from targeted sequencing of a single gene or a few genes linked to the disease to large gene panels; the latter “may not increase the likelihood of clinically actionable results in adult patients,” Dr. Musunuru and colleagues wrote.
But genetic testing is no guarantee to identify a cause or confirm a diagnosis of CVD, the statement noted. “The yield for any genetic testing for any inherited cardiovascular disease remains <100%, usually much less than 100%,” the writing committee stated.
Dr. Musunuru explained that the results can sometimes be inconclusive. “In many cases, genetic testing reveals a mutation that is uninterpretable, what we call a variant of uncertain significance,” he said. “It is not clear whether the mutation increases the risk of disease or is entirely benign, which makes it very challenging to counsel patients as to whether anything should be done about the mutation.”
Even in a diagnosed patient the test results can be uncertain. “This makes it challenging to explain why the patient has the disease and whether any of the family members are at risk,” Dr. Musunuru said.
According to the statement, providers should encourage patients with a confirmed or likely pathogenic variant for CVD to share that information with “all of their at-risk relative,” the statement noted, suggesting “family letters” given to patients are a way to navigate HIPAA’s privacy limits.
The statement was written on behalf of the American Heart Association’s Council on Genomic and Precision Medicine; Council on Arteriosclerosis, Thrombosis and Vascular Biology; Council on Cardiovascular and Stroke Nursing; and Council on Clinical Cardiology.

Do chocolate lovers have healthier arteries?
Adults who ate chocolate more than once a week or more than 3.5 times a month were significantly less likely to develop coronary artery disease than were those who ate less chocolate, according to data from a meta-analysis of more than 300,000 individuals.
Consumption of chocolate has shown beneficial effects on blood pressure and endothelial function, wrote Chayakrit Krittanawong, MD, of Baylor College of Medicine, Houston, and colleagues in the European Journal of Preventive Cardiology. “However, the potential benefit of increased chocolate consumption reducing coronary artery disease (CAD) risk is not known,” they said.
The investigators reviewed data from 5 decades of research, including six studies with a total of 336,289 individuals who reported chocolate consumption. The study participants experienced 14,043 cases of CAD, 4,667 myocardial infarctions, 2,735 cerebrovascular accidents, and 332 cases of heart failure over an average follow-up period of 8.78 years.
Overall, higher chocolate consumption (defined as more than once a week or more than 3.5 times a month) was significantly associated with a decreased CAD risk (pooled risk ratio, 0.94; P < .001) compared to eating no chocolate or eating chocolate less than once a week.
The cardioprotective effects of chocolate may be linked to several nutrients, the researchers noted. Chocolate’s flavenols (epicatechin, catechin, and procyanidins) have demonstrated an ability to reduce myocardial infarct size in an animal study and to reduce platelet aggregation and improve endothelial function in humans with and without CAD. In addition, methylxanthines have demonstrated beneficial effects on cardiovascular function, polyphenols have been shown to facilitate nitric oxide synthesis, and stearic acid has been associated with reduced mean platelet volume, they wrote.
“The benefits of nutrients in chocolate appear promising and chocolate consumption at least once a week may be beneficial for CAD prevention,” the researchers suggested, although they cautioned that the effects of supplemental calories and the impact of fats, milk, and sugar in commercial chocolate must be taken into account.
The study findings were limited by several factors, including the potential dietary confounders such as total energy intake and the type of chocolate consumed (milk, dark, or white) and the relatively homogeneous study population, which included mainly individuals from Europe and the United States.
Additional long-term, double-blind, randomized trials are needed to identify the cardioprotective effects of chocolate, and “studies to determine the role of genetic potential and the beneficial effects of chocolate on CAD may be needed,” the researchers noted.
However, the current study results suggest that “consumption of chocolates at least once a week is associated with a reduction in the risk of CAD,” they concluded.
The study received no outside funding. The researchers had no financial conflicts to disclose.
