No Advantage For Low Glycemic Index Diet Reply

In recent years the glycemic index (GI), a measure of a carbohydrate’s impact on blood sugar, has assumed a major role in discussions about diets and nutrition. Now a new study suggests that by itself, within the context of an otherwise healthy diet, GI may not be an important factor in improving cardiovascular risk.

In a paper published in JAMA, Frank Sacks and colleagues report the results of a randomized, crossover-controlled 5-week feeding trial comparing 4 different diets in 163 overweight or obese adults. The diets were either low- or high-carb and either low- or high-GI. Importantly, all the diets were based on previously established healthy dietary patterns based on the DASH diet, which is low in saturated and total fat and includes substantial amounts of fruits, vegetables, and low-fat dairy foods.

Get Rid of Sugar, Not Salt, Say Authors Reply

Too much negative attention has been focused on salt and not enough on sugar, write two authors in Open Heart. Reviewing the extensive literature on salt and sugar, they write that the adverse effects of salt are less than the adverse effects of sugar. The evidence supporting efforts to reduce salt in the diet is not convincing and we would be far better off reducing sugar instead of salt in the modern diet.

Women: Don’t Use Aspirin For Routine Prevention Of Heart Attacks, Stroke, And Cancer Reply

Although once widely recommended, aspirin for the prevention of a first heart attack or stroke (primary prevention) has lost favor in recent years, as the large number of bleeding complications appeared to offset the reduction in cardiovascular events. But at the same time evidence has emerged demonstrating the long-term effect of aspirin in preventing colorectal cancer, leading some to think that the risk-to-benefit equation for aspirin should be reconsidered.

Investigators in the Women’s Health Study therefore analyzed long-term followup data from 27,939 women who were randomized to placebo or 100 mg aspirin every other day.

No, The Mediterranean Diet Won’t Help You Live Forever Reply

A new study published today provides fresh evidence for the healthful effects of the Mediterranean Diet. It even suggests that people who follow the Mediterranean Diet may live longer than people on most other diets. And this is just the latest piece of good news about this diet to appear in the last few years. But I want to warn my readers not to go overboard with this study. It appears to be an excellent, well-performed study, but it has many inherent limitations and is by no means definitive. In the long run it may raise as many questions as it answers.

The new study, published in The BMJfinds that women who more closely followed a Mediterranean diet had longer telomeres on the end of their chromosomes…

Study Suggests Epinephrine for Cardiac Arrest May Be Harmful Reply

Epinephrine has been a cornerstone of therapy during cardiac resuscitation after cardiac arrest because of its well-established ability to stimulate the heart and increase the probability of a return of spontaneous circulation (ROSC). In recent years, however, concerns have been raised that people treated with epinephrine may have worse neurological outcomes following their resuscitation.

In a study published in the Journal of the American College of Cardiology, French researchers analyzed data from more than 1,500 patients who were successfully resuscitated after an out-of-hospital cardiac arrest and were subsequently treated at a large hospital in Paris….

Losartan No Better Than Atenolol in Marfan’s Syndrome Reply

Beta-blockers have been the standard treatment for people with Marfan’s syndrome, a rare inherited connective tissue disorder that affects about 1 in 5000 people. The goal of treatment is to prevent or slow down the dilation of the aorta and avoid aortic dissection, the main cause of death. In recent years, studies have raised the hope that losartan, an angiotensin receptor blocker, might be more effective than beta-blockers in slowing aortic enlargement.

The Pediatric Heart Network Investigators randomized 608 children and young adults with Marfan’s syndrome to the beta-blocker atenolol or losartan….

HDL Raising Drugs Probably Won’t Work But This Might 1

A new study offers important new insights into the protective role of HDL cholesterol (the “good” cholesterol) against cardiovascular disease. Earlier studies with drugs that increase HDL levels, including niacin and CETP inhibitors, have not shown benefit. The new study suggests that simply increasing HDL levels isn’t the way to go. Instead, cholesterol efflux, the ability of HDL to remove cholesterol from cells, part of the process called reverse cholesterol transport, appears to be the key. The results were presented today by Anand Rohatgi at the American Heart Association meeting in Chicago and published simultaneously in the New England Journal of Medicine.

The investigators followed 2,416 people participating in the Dallas Heart Study who were free of cardiovascular disease at the start for 9.4 years….

Large Japanese Trial Casts Further Doubt On Aspirin To Prevent A First Heart Attack Reply

Although once quite popular, the use of aspirin to prevent a first heart attack has grown less popular in recent years as evidence has accumulated that the small benefits are outweighed by the increased risk of bleeding. Now a large trial from Japan has once again failed to provide any evidence to support the use of routine aspirin in high risk elderly people to prevent a first cardiovascular event.

The Japanese Primary Prevention Project (JPPP),  presented at the American Heart Association meeting in Chicago and published simultaneously in JAMA, enrolled  patients between 60 and 85 years of age with  hypertension, dyslipidemia, or diabetes. The open label study randomized 14,464 patients to aspirin 100 mg once daily or no aspirin in addition to conventional therapy. Patients were followed for up to 6.5 years for the primary combined endpoint of cardiovascular death, nonfatal stroke, or nonfatal MI….

IMPROVE-IT Meets Endpoint And Demonstrates Real But Modest Clinical Benefit For Ezetimibe Reply

After all the waiting and all the controversy it turned out to be pretty simple. The IMPROVE-IT trial did what it set out to do and reached its primary endpoint. The benefit wasn’t very big or impressive but it will be enough to put to rest concerns that ezetimibe might have been an expensive placebo or that LDL might not be a reliable surrogate endpoint. The IMPROVE-IT results will also provide comfort to companies developing the next generation of cholesterol drugs, since their approval may have depended on validation of LDL as a surrogate endpoint.

The  Improved Reduction of Outcomes: Vytorin Efficacy International Trial, presented Monday morning at the American Heart Association meeting in Chicago, randomized 18,144 high-risk patients within 10 days of an acute coronary event to either ezetimibe or placebo on top of a statin….

IMPROVE-IT Trial Paper Won’t Be Published Right Away In The New England Journal Of Medicine 1

The presentation of the eagerly awaited IMPROVE-IT trial, scheduled for Monday at the American Heart Association meeting, won’t be accompanied by a simultaneous publication in the New England Journal of Medicine. Although no one except for a small group of insiders knows for sure, this news may have important implications.

Newly Identified Mutations Act Like a Lifetime of Treatment with Ezetimibe Reply

A very large genetic study published in the New England Journal of Medicine offers compelling evidence in support of a central role for LDL cholesterol in coronary heart disease.

In a series of studies analyzing blood samples from nearly 100,000 people, Sekar Kathiresan and colleagues identified 15 rare mutations that block the activity of a single gene — called Niemann-Pick C1-Like 1 (NPC1L1). The mean LDL level was 12 mg/dL lower in mutation carriers than noncarriers. There were just 11 carriers of the mutations among 29,954 people with CHD versus 71 carriers among 83,140 people without known CHD (carrier frequency: 0.04% vs. 0.09%).  This worked out to a 53% reduction in CHD risk for mutation carriers.

Popular Diets Achieve Only Modest Long-Term Weight Loss Reply

Four of the most popular current weight loss diets produce at best only modest long-term benefits, a new study published in Circulation: Cardiovascular Quality and Outcomes shows. The study also found few significant differences across the four diets, offering little hope that any one diet can produce a serious dent in the obesity epidemic.

Mark Eisenberg and colleagues systematically searched the literature for studies evaluating the effects of the Atkins, South Beach, Zone, and Weight Watchers diets. They identified 12 randomized, controlled studies with follow-up of at least 1 year. Ten studies compared one of the diets with usual care. In these trials, Weight Watchers was the only diet to consistently outperform usual care in achieving weight loss, but this difference was modest at best, yielding a 1-year weight loss range of 3.5 to 6 kg with Weight Watchers compared with 0.8 to 5.4 kg with usual care. In the two head-to-head trials, Atkins and Zone resulted in a similar but modest weight loss. Longer-term data out to 2 years — available only for the Weight Watchers and Atkins diets– showed that some of the original weight loss was regained over time. Only one small trial studied the South Beach diet.

What You Need To Know About IMPROVE-IT Reply

The IMPROVE-IT trial will be big news when its results are finally presented on November 17 during the annual meeting of the American Heart Association. The results of the trial–underway for nearly a decade– have been long and eagerly awaited by everyone interested in cardiovascular medicine.  The trial could impact the future sales of a key Merck drug, ezetimibe, though because it is nearing the end of its patent life the commercial significance is somewhat limited. However, IMPROVE-IT will also have very important implications beyond its specific effect on one drug franchise and could influence the fate of several new drugs now being investigated and may even alter the entire drug development and evaluation process.

Here’s some background information and links to useful resources.

Economic Study Finds VTE Prophylaxis with Low-Molecular-Weight Heparin Cost Effective Reply

Critically ill patients in the hospital are at high risk for developing venous thromboembolism (VTE). The 2011 PROTECT trial compared the two most common drug strategies used to prevent VTE — unfractionated heparin (UFH) and dalteparin, a low-molecular-weight heparin (LMWH) —  and found no difference between the two groups in the primary endpoint of the trial, leg deep-vein thrombosis.

But PROTECT did turn up a significant reduction in the dalteparin group in the important secondary endpoints of pulmonary embolism (PE) and heparin-induced thrombocytopenia (HIT). Now a prespecified economic analysis of PROTECT, published in JAMA, indicates that use of LMWH, though it is more expensive than UFH, may lead to lower hospital costs due to the reduction in PE and HIT.

Aortic Valve Surgery for Nonagenarians Reply

As people continue to live longer physicians are increasingly confronted with very elderly patients who have serious conditions that might benefit from surgery but who are at high risk for surgical complications. In a paper published in the Annals of Thoracic Surgerydoctors at the Mayo Clinic reviewed their experience with 59 patients age 90 or older who had severe aortic stenosis and underwent surgical (SAVR) or transcatheter aortic valve replacement (TAVR).

Ebola, Natural Cures, And Panic: A Rant Reply

I try to stick to writing about cardiovascular topics but it’s been hard to avoid thinking about ebola in recent weeks. Trying to take a break from the ebola insanity yesterday I turned to Facebook to find some cute cat videos. Instead, I found this, posted by an old friend, from the Organic Consumers Association:

There are natural methods proven to be effective for prevention and treatment of Ebola. But doctors refuse to explore them.

My friend simply asked her FB friends: “What do you think? Please share.”

Genetic Study Suggests Possible Causal Role for LDL in Aortic Valve Disease Reply

Although LDL is an important risk factor for aortic valve disease, the precise role it plays has been uncertain. Lipid-lowering therapy in people with established aortic valve disease has not been shown to be beneficial. Now, however, a new genetic study published in JAMA suggests that LDL cholesterol may in fact cause an increase in aortic valve calcium and aortic valve stenosis. This may mean that LDL-lowering therapy could prove beneficial when given earlier in the disease process.

Paper Behind The Green Coffee Bean Diet Craze Retracted Reply

The “scientific” paper that helped ignite the green coffee bean diet craze has been retracted. The details of the retraction and the full background of the story were fully reported by Ivan Oransky on Retraction Watch.

The paper, published in Diabetes, Metabolic Syndrome and Obesity: Targets and Therapy, purported to report the substantial weight loss findings of a randomized, double-blind, placebo-controlled crossover study of green coffee bean extract. The article has been viewed or downloaded by more than three-quarters of a million people since its publication in January 2012.

Previous Stories About HDL:

Doctor: You’re Going To Have A Heart Attack! Patient: Your Tests Results Are Giving Me A Heart Attack! Reply

Last month I wrote a series of articles (starting here) about HDL, a laboratory company under investigation by the DOJ for giving kickbacks to physicians who use their tests. I reported additional allegations of serious misconduct based on questionable sales, marketing, and billing practices involving unnecessary testing. In response to those articles I’ve received emails from several individuals, including a patient and a health care provider, whose stories appear to confirm and provide additional perspective about the allegations in the earlier articles.

Another Diet Myth Exploded: Gradual Weight Loss No Better Than Rapid Weight Loss Reply

Once again, a popular weight loss myth has been exploded. It has been widely believed that weight loss, which is nearly always difficult to maintain, is even less likely to stay lost if it is the product of a rapid weight loss. The belief is even enshrined in current guidelines. Now a study published in The Lancet Diabetes & Endocrinology provides no support for this view. Instead, the study suggests that although long-term weight loss remains elusive regardless of the diet, short-term weight loss is actually more likely with rapid weight loss.

Medicare Reimbursement for Lung Cancer Screening Provokes Debate 1

Although 160,000 people in the U.S. die each year from lung cancer, accounting for more than a quarter of all cancer deaths, screening for lung cancer remains controversial. Based on results from the National Lung Screening Trial (NLST) in 2011, the U.S. Preventive Services Task Force (USPSTF) issued a B recommendation in favor of low-dose CT screening for high-risk current and former smokers. Due to a provision in the Affordable Care Act, private insurance is now mandated. More recently, the Medicare Evidence Development & Coverage Advisory Committee (MEDCAC) concluded that there is only low to intermediate confidence that “there is adequate evidence to determine if the benefits outweigh the harms.” The Centers for Medicare and Medicaid Services (CMS) is expected to issue a final decision on national coverage in 2015.
