HDL Raising Drugs Probably Won’t Work But This Might

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…

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

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…

New Evidence Fuels Concerns About The Safety Of Niacin

The string of failures– for HDL therapies in general and for niacin in particular– continues unabated.  The publication of the main results of the HPS2-THRIVE trial, along with new information from the AIM-HIGH trial, provide no evidence of a beneficial effect for niacin but do fuel concerns that it may cause serious adverse effects. ……

Large Genetic Studies May Help Unravel The Triglyceride Problem

The precise role of triglycerides in heart disease has been very difficult to determine. To help untangle the knotty problem two research groups studied large populations and identified rare variations in a gene (APOC3) that encodes for apolipoprotein C3, which is known to increase triglyceride levels. … The two studies have received a lot of…

Another Failed HDL Therapy Trial

Despite robust epidemiological evidence suggesting that HDL has a strong protective effect against cardiovascular disease, there has been no good evidence showing that HDL-based therapies are beneficial. Large trials of drugs that raise HDL levels, including niacin and CETP-inhibitors, have failed to demonstrate improvements in outcome. Some observers gleaned hope from several small studies of…

Slouching Toward Phase 3: Progress Report On New Cholesterol Drugs At The AHA

The American Heart Association meeting in Dallas this year brought new phase 2 data about several promising new cholesterol drugs. But before jumping on any bandwagons it would be good to remember that even for the drugs most far along in development we still haven’t seen any phase 3 data. In addition, it bears repeating that the…

WSJ Article Fails To Raise Key Questions About Cardiovascular Risk In Children

There’s probably no greater public health issue than the long-term  consequences of the childhood obesity epidemic. So the Wall Street Journal should be commended for digging into some of the important science behind this problem in a feature article in today’s paper. The author, Ron Winslow, is widely regarded as the best working journalist who…

Should Niacin Still Be Prescribed? William Boden Versus Harlan Krumholz

Harlan Krumholz

In the wake of HPS2-THRIVE many have argued that there is no longer any reason to prescribe niacin. William Boden, the lead investigator of AIM-HIGH and COURAGE, thinks there were enough flaws in the design of the niacin trials to justify the cautious use of niacin in certain circumstances. Says Boden: “There is evidence of…

2012 In Review: A Bad Year For Conventional Wisdom

This was a really grim year for anyone who thought we had things pretty well figured out. Time and again conventional wisdom was thrown out the window. 2012 forced the cardiology community to reconsider what it thought it knew about HDL cholesterol, platelet function tests, aspirin resistance, triple therapy, IABP, and more. One device company,…

Early Look: New Methods To Enhance Cholesterol Efflux

Although clinical trials of HDL-boosting CETP inhibitors have so far failed to produce positive results, many other avenues of HDL-related research remain active.  A glimpse at the very early phases of two intriguing lines of research in this area was offered on Monday at the AHA. Apo A-1 is thought to be the key HDL…

You Know Nothing, Dr. Snow: Why Medicine Can’t Be More Like Facebook

Medicine can never be like Facebook, despite what Matt Herper argues over at Forbes. Perhaps he was just trolling for hits on a day when everyone is thinking about the Facebook IPO, but Herper proposed, with apparently seriousness, that medicine needs to model itself on the tech world in order to match the kind of…
