Good and Bad News for Reducing Heart Attack Deaths
Good and bad news often go together, for what is good news for some is bad for others. Shareholders in pharmaceutical companies that produce statins will have been heartened (no pun intended) by a paper in a recent edition of the New England Journal of Medicine in which the authors calculated that, under the new guidelines of the American College of Cardiology and the American Heart Association with regard to lipid levels in the blood, 12.8 million more adults in the United States alone would be "eligible" for (i.e. ought ideally to have) treatment with statins. In fact, very nearly half the population older than 40 ought to take them, and seven eighths of the population over 60. As a man over sixty who never has any blood tests done, my heart sinks (again no pun intended). We are all guilty of illness until proven healthy: not good news.
The authors compared the therapeutic consequences of the old guidelines with the new. In effect the new guidelines lowered the threshold for treatment. According to these guidelines, anyone over 40 with known cardiovascular disease should receive statins, irrespective of their level of Low Density Lipoprotein (LDL); while anyone with a level of 70 milligrams per decilitre or more and who has diabetes or a statistical risk of a heart attack of more than 7.5 percent within the next ten years should also receive them.
Taking a rather small sample of adults over 40 from the National Health and Nutrition Examination Survey whose blood lipids were measured and extrapolating it to the U.S. population as a whole, the authors conclude that, if the new guidelines were put into practice rather than the old, 14.4 million adults in the U.S. who would not have been "eligible" for treatment under the old guidelines would now be "eligible" for it, while 1.6 million who would have been "eligible" under the old guidelines would no longer be "eligible."
