The risk of congestive heart failure: sobering lessons from the framingham heart study
- 176 Downloads
This review highlights recent contributions of the Framingham Heart Study to our understanding of the epidemiology of congestive heart failure (CHF). Given its uniform criteria for the diagnosis of CHF and its long duration of follow-up, the Framingham study has had a unique perspective on the short- and long-term risk of developing CHF, its predisposing risk factors, and its prognosis in a general, community-based population. Some recent studies from Framingham have provided important insights on CHF: the lifetime risk is estimated to be 20% for men and women; hypertension is the most important modifiable risk factor, with a population-attributable risk of CHF of 59% for women and 39% for men; a clinical prediction rule for development of CHF has recently been published; and the prognosis after development of CHF is grim, with a median survival of 1.7 years in men and 3.2 years in women.

An elegant examination of the role that hypertension plays in the development of CHF. In this study, 91% of subjects with CHF had antecedent hypertension. The multivariate-adjusted hazard ratios and population-attributable risks for key risk factors for CHF are presented and discussed, as is the prognosis after development of CHF.PubMedCrossRefGoogle Scholar

J Am Coll Cardiol 1999, 33:1948–1955. This nested case-control study examined the prevalence of normal (51%) versus reduced (49%) left ventricular systolic function among subjects with CHF, and the outcomes associated with each clinical picture. Although the absolute annual mortality was lower among subjects with normal systolic function compared with reduced systolic function, the relative hazard ratios were the same when each group was compared with matched controls.PubMedCrossRefGoogle Scholar
