Death rates for heart disease and stroke drop significantly
The rates fell about 30% between 1999 and 2006. A UCLA cardiologist calls it 'one of the most remarkable achievements of modern medicine.'
The death rates for heart disease and stroke each dropped by about 30% between 1999 and 2006, allowing the American Heart Assn. to reach its 2010 goal of a 25% reduction in deaths four years early, researchers said today.
"It's one of the most remarkable achievements of modern medicine to have this kind of decline," said Dr. Gregg C. Fonarow, a cardiologist at UCLA's Geffen School of Medicine who was not involved in the research. "But there is still obviously a lot of work to be done. We still have the number one and three killers of men and women in the United States."
The association had already announced in January that it had achieved its goal for heart disease and was close to achieving its goal for strokes.
But experts fear the declines may soon be reversed.
"Although death rates are declining, several of the risk factors leading to heart disease are increasing," said Dr. Suzanne Steinbaum of Lenox Hill Hospital in New York, an American Heart Assn. spokeswoman. "There is an increase in obesity, diabetes and physical inactivity, which all lead to heart disease and stroke."
The annual report, published online today in Circulation: Journal of the American Heart Assn., in cooperation with the Centers for Disease Control and Prevention and the National Institutes of Health, showed that death rates in the U.S. from heart disease and stroke each dropped about 5% from 2005 to 2006, the most recent year for which data were available.
Including the new data for 2006, researchers found a 30.7% reduction in heart disease deaths since 1999 and a 29.2% reduction in stroke deaths.
Fonarow said those gains were fueled by better preventive care for people in high-risk groups, more effective treatments in hospitals for those suffering heart attacks and strokes, and better care to prevent recurrences after a first episode.
Nonetheless, 829,072 Americans died of heart attack and stroke in 2006, 34.2% of the total, or 1 in every 2.9 deaths. Nearly 2,400 Americans die of cardiovascular disease each day, an average of one death every 37 seconds.
Total cholesterol levels, a major risk factor for heart disease, decreased about 2% during the study period for men over 40 and women over 60, but remained steady for younger people despite the growing use of cholesterol-lowering statins.
Obesity, another risk factor, is climbing. The percentage of children in the 95th percentile for obesity rose from 4% in 1971-74 to 17% in 2003-06, the report said.
