Mike Eades, More on Statins


Do they have enough "critical thinking skills to wonder about the hypothesis that LDL-cholesterol is really a problem.
The next day the New York Times, in an article that wasn’t all that anti-statin, started thusly:
For decades, the theory that lowering cholesterol is always beneficial has been a core principle of cardiology. It has been accepted by doctors and used by drug makers to win quick approval for new medicines to reduce cholesterol.
But now some prominent cardiologists say the results of two recent clinical trials have raised serious questions about that theory — and the value of two widely used cholesterol-lowering medicines, Zetia and its sister drug, Vytorin. Other new cholesterol-fighting drugs, including one that Merck hopes to begin selling this year, may also require closer scrutiny, they say.
Dr. Steven E. Nissen weighed in with his interview with Katie Couric on CBS that I posted earlier.
And the Wall Street Journal in it’s Health Blog anticipated a slew of lawsuits against the makers of Vytorin and maybe other statins to follow.
But the big daddy of them all has yet to hit the newsstands but has already been blasted over the internet. The next issue of Business Week, due to hit the stands next Monday, has been up online for the past few days, and it contains several articles, including the cover article, that are devastating for the makers of statin drugs.
The cover article titled Do Cholesterol Drugs Do Any Good starts right off in lock step with what I wrote in my Queen Mother of all statin posts a year or so ago. The Business Week piece starts with an interview with James M. Wright, a professor at the University of British Columbia and the director of the Canadian government-funded Therapeutics Initiative, an agency that analyzes drug data to see how well they actually work. Dr. Wright had one of his patients – Martin Winn – on a statin for a mildly elevated cholesterol level when the light bulb flashed on.
Wright saw, the drugs can be life-saving in patients who already have suffered heart attacks, somewhat reducing the chances of a recurrence that could lead to an early death. But Wright had a surprise when he looked at the data for the majority of patients, like Winn, who don’t have heart disease. He found no benefit in people over the age of 65, no matter how much their cholesterol declines, and no benefit in women of any age. He did see a small reduction in the number of heart attacks for middle-aged men taking statins in clinical trials. But even for these men, there was no overall reduction in total deaths or illnesses requiring hospitalization—despite big reductions in “bad” cholesterol. “Most people are taking something with no chance of benefit and a risk of harm,” says Wright. Based on the evidence, and the fact that Winn didn’t actually have angina, Wright changed his mind about treating him with statins—and Winn, too, was persuaded. “Because there’s no apparent benefit,” he says, “I don’t take them anymore.”
As I reported in my post the only evidence that statins produce any decrease in all-cause mortality is in men under the age of 65 who have established heart disease. For women of all ages with and without heart disease and for men of all ages without heart disease, these drugs don’t bring about a decrease in all-cause mortality.
