Mitral-Valve Prolapse Less Common, Less Harmful Than Previously Thought

Summary:
Researchers from the National Heart, Lung, and Blood Institute's (NHLBI) Framingham Heart Study report that mitral-valve prolapse (MVP), a condition in which a valve in the heart is abnormally long and floppy, is substantially less common and less serious than previously believed.

Researchers from the National Heart, Lung, and Blood Institute's (NHLBI) Framingham Heart Study report that mitral-valve prolapse (MVP), a condition in which a valve in the heart is abnormally long and floppy, is substantially less common and less serious than previously believed. In a study appearing in the July 1, 1999 issue of The New England Journal of Medicine, the researchers report that MVP affects about 2 percent of the population rather than the 5 to 35 percent of the population indicated in earlier estimates. And, contradicting earlier studies suggesting that MVP occurs more commonly in women, the researchers found that men and women are equally likely to have the condition. "This is very compelling information," said Dr. Claude Lenfant, Director of the NHLBI, "It may mean people who have been diagnosed with mitral valve prolapse should consult their physician to discuss their health status. It also indicates that further, longer-term studies are called for to resolve this issue definitively and to define the natural history of this condition," he said.
