Two studies focus on population trends in cardiovascular disease.
In one study, researchers used data from the National Health and Nutrition Examination Survey (NHANES) to determine 10-year coronary heart disease risk (according to Framingham calculations) during two periods — 1988–1994 and 1999–2004. Ten-year risk declined from 6.5% to 5.9% among 35- to 44-year-old men, and from 11.9% to 10.6% among 45- to 54-year-old men. No significant changes over time were observed among women in either age group (risk, 1.6% and 5.1%).
In another study, researchers used data from the National Registry of Myocardial Infarction to examine in-hospital mortality for men and women who presented with acute coronary ischemia from 1994 to 2006. Declines in hospi…
