Physicians are finally getting a handle on preventing heart attacks.
A study of more than 46,000 Northern California Kaiser Permanente patients found a significant drop in heart attacks over a 10-year period, and more importantly, a major decrease in the most serious type of heart attacks - results that show that communitywide efforts to help people reduce their risk of heart disease seem to be working, doctors say.
The study, published in today's issue of the New England Journal of Medicine, showed that the heart attack rate among Kaiser patients fell 24 percent between 1999 and 2008 - the rate increased from 1999 to 2000, but declined every year after that. The types of heart attacks that do the most damage - known as ST-segment elevation heart attacks - fell 62 percent.
Over the same time period, more Kaiser patients lowered their blood pressure and cholesterol levels, and smoking rates decreased. The use of medications like beta-blockers and aspirin that are known to prevent heart disease increased. It would seem, authors of the study noted, that these preventive measures are working, perhaps even better than expected.
"Researchers keep trying to find more ways to treat heart attacks, but we need to focus just as much attention on things that we know work now, and doing those things on a large scale: adopting healthier lifestyles, stopping smoking, taking medications," said Dr. Alan Go, an author of the study and director of the Comprehensive Clinical Research Unit at the Kaiser Permanente Division of Research in Oakland.
