American Heart Association: Pay More Attention to Radiation in Imaging Procedures Reply

The American Heart Association is urging physicians to better understand the risks of radiation in cardiac imaging procedures. When ordering these procedures physicians should understand the appropriate use of each procedure, the radiation dose associated with the procedure, and the risks associated with that dose. Both the risks and benefits should be fully explained and discussed with patients prior to the imaging procedure.

The full importance of radiation from cardiac procedures is not always appreciated, write the authors of the newly published scientific statement, “Approaches to Enhancing Radiation Safety in Cardiovascular Imaging.” But, according to Reza Fazel, the chair of the writing committee, “heart imaging procedures account for almost 40 percent of the radiation exposure from medical imaging.”

Why Bad Doctors Are Like Bad Writers: The Curse Of Knowledge Reply

Steven Pinker, the Harvard psychologist and best-selling author, has a wonderful essay in the Wall Street Journal about why smart people are so often bad writers. Although the essay doesn’t touch on the subject of doctor-patient communication, every single word applies to doctors and the way they communicate (or fail to communicate) with their patients.

Here’s the core of Pinker’s argument. Read the rest of it. And if you’re a doctor and you don’t see how this is relevant to how you communicate with your patients then you need to think again.

New England Journal Of Medicine Declines To Retract Papers From Disgraced Research Group 3

Like the Leaning Tower of Pisa, the two New England Journal of Medicine papers by disgraced Dutch researcher Don Poldermans will never stand straight. But like the famous Tower they are also unlikely to topple anytime soon. Without attracting a lot of attention, back in August the NEJM editors decided not to retract the papers or publish an expression of concern. But they did add an “Editor’s note” to the articles referring readers to a Dutch investigation into the studies.

Embattled HDL Laboratory CEO Resigns Amid Federal Investigation Reply

Tonya Mallory, the embattled President and CEO of troubled Health Diagnostics Laboratory, has resigned her positions, the company announced today. Mallory said she was leaving to help her brother start a new business. Dr. Joe McConnell, a co-founder of the company and its Chief Laboratory Officer, will succeed her. Mallory will remain on the HDL Board of Directors.

As previously reported (by the Wall Street Journal and here) the federal government is investigating HDL for giving kickbacks to physicians  who use  the company’s tests. Additional allegations suggest a broader pattern of serious misconduct based on questionable sales, marketing, and billing practices regarding unnecessary testing.

A ‘Disappeared’ Article, Finally Published, Finds A Desultory Response To Scientific Misconduct Reply

Back in January an article in the European Heart Journal raising the disturbing possibility that guidelines based on fraudulent research may have been responsible for as many as 800,000 deaths was “disappeared” from the journal’s website only minutes after being published. The journal’s editor claimed the article had not been properly peer reviewed. In its place the editors published an editorial refuting the claims of the article, though of course they were responding to an article that no one could then actually read. Now, eight months later, a revised version of the original article, by British cardiologists and gadflies Graham Cole and Darrel Francis, has finally been published. The new version raises even more disturbing questions about the potentially lethal effects of such fraudulent research not only on clinical practice but on the credibility and worth of the entire scientific enterprise.

Cardiology Group Withdraws ‘Choosing Wisely’ Recommendation Reply

In the end it wasn’t wisdom for the ages. The American College of Cardiology said today that it was withdrawing one of its five recommendations in the “Choosing Wisely” campaign.  In 2012 the ACC recommended that heart attack patients should have only their culprit artery unblocked. It said that patients and caregivers should question whether complete revascularization of all nonculprit lesions in heart attack patients should be performed.

The original recommendation was based on non-randomized studies suggesting that treating all significantly blocked vessels in heart attack patients could be harmful. “However,” the ACC now states, “over the last two years, new science has emerged showing potential improvements for some patients in their overall outcomes as a result of complete revascularization.”

Counterintuitive Advice About Staying Alive After A Heart Attack 1

An interventional cardiologist– the cardiologists who put in stents and usually treat heart attack patients in the first few hours– asked an electrophysiologist– the cardiologists who treat arrhythmias– whether wearable defibrillators should be used post-MI. Here’s what that electrophysiologist, Edward J. Schloss, the medical director of cardiac electrophysiology at Christ Hospital in Cincinnati, OH, replied. It is a good example of how sometimes a procedure or a therapy that seems, intuitively, to be worthwhile and beneficial, may actually not be beneficial at all. Here’s his response, which he originally posted on Twitter:

Amarin Says It Will Complete Cardiovascular Outcomes Trial For Its Fish Oil Pill Reply

After nearly a year of uncertainty, Amarin  announced  its commitment to complete REDUCE-IT  (Reduction of Cardiovascular Events with EPA – Intervention Trial). The trial is designed to test the effects on cardiovascular outcomes of Vascepa, the company’s high EPA omega-3 prescription fish oil product, in people with moderately elevated triglyceride levels between 200-499 mg/dL.

Last year the company said it might discontinue support of the trial, which began in 2011, after the FDA turned down the company’s application for an expanded indication for Vascepa.

Cheaper Generic Statins Beat Brand-Name Statins in Adherence and Outcomes Reply

A large observational study finds that people who received a prescription for a generic statin were more likely to take their pills than people who received a prescription for a brand-name statin. This increased adherence appeared to lead to a small but significant improvement in outcomes.

ACC And AHA Don’t Recommend Routine ECG Screening Of Young People Reply

In a new scientific statement the American Heart Association and the American College of Cardiology do not recommend the routine initial use of ECGs to screen young people for underlying congenital or genetic heart disease.

More aggressive screening for heart disease in young people is often advocated in response to pressure resulting from the rare but tragic cases of sudden death in young people. But a detailed examination of the evidence led the AHA/ACC group to conclude that routine initial ECG screening “in healthy people 12-25 years old without positive findings on the history and physical examination has not been shown to save lives.”

Japanese Research Scandal Involving Novartis Blood Pressure Drug Widens Reply

The Japanese scandal over research using the Novartis blockbuster hypertension drug Diovan (valsartan) continues to widen. The first major figure brought down in the scandal was Hiroaki Matsubara, a prominent cardiologist and researcher at Kyoto Prefectural University in Japan, who  resigned from his position after numerous retractions and investigations. Then last year accusations surfaced about another prominent researcher, Issei Komuro, a professor at Chiba University.

Chiba University has now completed an investigation of one of Komuro’s most important papers, the 2011 report of the Valsartan Amlodipine Randomized Trial (VART), published in Hypertension Research, which is the official journal of the Japanese Society of Hypertension.

FDA Advisory Panel Offers Cautious Support For Polypill Reply

The controversial polypill took one step closer to reaching the US market after receiving a mostly positive reception from the FDA’s Cardiovascular and Renal Drugs Advisory Committee on Wednesday. The idea for the polypill– which in this case would be composed of aspirin, a statin, and one or more blood pressure drugs– has been kicking around for more than a decade and has attracted considerable doses of support as well as skepticism.

An all-star group of cardiology leaders– including Sir Nicholas Wald, Salim Yusuf, Suzanne Oparil, Sidney Smith, and Clyde Yancy– helped provide the spoonful of sugar that helped the committee swallow the polypill. The FDA also eased the way by limiting the discussion to the use of the polypill for secondary prevention in people who have already had a MI or a stroke.

Statins And Diabetes: A Clearer Picture Emerges Reply

In recent years, the medical community has become increasingly aware that taking statins can result in slightly higher glucose levels, and this can lead to a diagnosis of diabetes in a small but statistically significant number of people. But it has been unclear whether the diagnosis of diabetes in people taking statins also places them at increased risk for the microvascular complications linked to diabetes. Now, an observational study published in the Lancet Diabetes & Endocrinology finds that among people newly diagnosed with diabetes, statin users are less likely than nonusers to develop most of these complications. (The beneficial effects of statins in reducing macrovascular complications — cardiovascular disease — in diabetics and others is well established in people at high risk for these events.) 

Danish researchers examined the rate of microvascular outcomes in more than 15,000 statin users who developed diabetes and 47,000 nonusers of statins who developed diabetes.

Beyond Kickbacks: More Questions About Unnecessary Cardiovascular Tests Reply

On the front page of the Wall Street Journal today is an important story about a fast-growing company accused of giving kickbacks to physicians who order the company’s tests measuring a wide variety of cardiovascular biomarker tests. But the article leaves one major question unasked: even if the company played fully by the rules, are most of the tests medically necessary?

In their story John Carreyrou and Tom McGinty write about a government investigation into Health Diagnostic Laboratory Inc. (HDL), which was started in 2008 and had $383 million in revenue last year. HDL sells tests that measure cardiovascular biomarkers and “bundles together up to 28 tests it performs on a vial of blood, receiving Medicare payments of $1,000 or more for some bundles.”

Early Hint At Cardiovascular Outcomes With Sanofi’s and Regeneron’s Rapidly Advancing Cholesterol Drug Reply

Amid a slew of new data demonstrating yet again that PCSK9 inhibitors lower LDL cholesterol– drastically and in a wide variety of different patient populations– data from one trial offers the first suggestion that the drugs may in fact improve cardiovascular outcomes. But the analysis, the authors cautioned, is a post-hoc analysis of a trial neither designed nor powered to study outcomes, so should be considered preliminary and speculative at best.

Four phase 3 trials with the Sanofi and Regeneron PCSK9 inhibitor alirocumab (pronounced “allee rock you mab” by Chris Cannon at a news conference) were presented today at the European Society of Cardiology meeting in Barcelona.

SIGNIFY Trial Provokes Sound And Fury Over Controversial Servier and Amgen Drug Reply

The controversial drug ivabradine just got a little more controversial. The drug, which is marketed by Servier under the brand names of Corlentor and Procoralan, is available in Europe and elsewhere and is used for the treatment of heart failure and stable angina. The drug is not available in the US, but it is under development by Amgen for a heart failure indication.

Now a very large new study presented at the European Society of Cardiology meeting in Barcelona and published simultaneously in the New England Journal of Medicine has found no evidence of benefit in a stable angina population and found more adverse events associated with the drug and even suggested the likelihood of harm in a very large and important trial subgroup. The findings have resulted in an investigation by the European Medicines Agency, placing a cloud over the future status of the drug.

Silencio! Claiming Pressure From European Regulators, Trial Leaders Cancel Press Conference Reply

Investigators of the much-anticipated and controversial SIGNIFY trial have told the European Society of Cardiology leadership that they will not participate in a previously scheduled press conference on Sunday at the society’s main meeting in Barcelona. But they say they will present the main results of their trial at a Hot Line session later in the afternoon.

According to the ESC, the SIGNIFY investigators, who include Kim Fox, Ian Ford, Philippe Gabriel Steg, Jean-Claude Tardif, Michal Tendera, and Roberto Ferrari, told the ESC leadership that regulators at the European Medicines Authority (EMA) had told the investigators that because they (the investigators) were scheduled to appear before the EMA they should not discuss or comment on their trial outside the official presentation at the ESC conference.

PARADIGM-HF Establishes a New Paradigm for Heart Failure Treatment Reply

So far as I can tell the only problem with PARADIGM-HF is that the results are so good that it’s boring. Anyone interested can reasonably assume that what they hear or read about PARADIGM-HF — and cardiologists will be seeing and hearing an awful lot about it —  will be overwhelmingly positive.

Briefly, the trial did everything its sponsor (Novartis) and its investigators (led by Milton Packer and John McMurray) hoped. It met all its major endpoints in all the subgroups without raising any sort of a safety signal. If the findings are confirmed after a rigorous FDA review, then Novartis will likely have a blockbuster on its hand.

All the excitement is over a new drug still known only by its number, LCZ696.

Rise In Popularity Of E-Cigarettes Sparks Concerns And Recommendations Reply

The recent dramatic rise in popularity of e-cigarettes threatens to reverse hard-fought progress in the war against smoking, according to a new policy statement from the American Heart Association. “E-cigarettes have caused a major shift in the tobacco-control landscape,” said the lead author of the statement, Aruni Bhatnagar, chair of cardiovascular medicine at the University of Louisville.

But the AHA did not completely reject the use of e-cigarettes as an aid to stop smoking.

Why Guidelines Should Be Waged Like War 1

Here’s a modest proposal: we need fewer and shorter guidelines. In fact, I’d like to propose that guidelines, like war, should be waged only when there is absolute consensus and overwhelming evidence.

Anyone interested in the subject is aware that guidelines are in a complete mess.

Increased Heart Risk Linked To Popular Antibiotic Reply

Acute use of the popular macrolide antibiotic clarithromycin has been linked to a small but significant increase in cardiac death. In a report in the BMJ, researchers in Denmark analyzed the effects over a 14-year period of the acute use of penicillin V, roxithromycin, and clarithromycin.

Earlier research raised concerns that marcrolide antibiotics in general, and erythromycin and azithromycin in particular, might prolong the QT interval and increase the risk for fatal arrhythmias.

In the new study, clarithromycin was associated with a significant increase in the rate of sudden cardiac death compared with the other two antibiotics…
