Incidence and mortality of heart failure: a community-based study.
BACKGROUND
Data on the incidence and mortality of heart failure (HF) in community-based populations of developed countries are limited. We estimated the trends of the incidence and, the mortality of HF.


METHODS
Prospective population-based study in a white, low-middle class Mediterranean community of 267,231 inhabitants in Spain. Participants were all the patients (=>14 years), newly diagnosed with HF (4793), according to the Framingham criteria, from January 1, 2000 through December 31, 2007. Main outcome were incidence and mortality following an HF diagnosis.


RESULTS
Incidence of HF increased among both men and women, and among persons with systolic and non-systolic HF. Incidence of HF increased from 296 per 100,000 person-years in 2000 to 390 per 100,000 person-years in 2007 (RR 1.32, CI 95% 1.27-13.7, P<.01). Although, risk-adjusted mortality declined from 2000 to 2007, the prognosis for patients with newly diagnosed HF remains poor. In 2007, risk-adjusted 30-day, 1-year, and 4-years mortality was 12.1%, 28.8%, and 61.4%, respectively. Incidence and mortality of systolic HF were higher than those of non-systolic HF (P<0.05).


CONCLUSIONS
During the last 8 years, in a white, middle class population of the south of Europe, the increased incidence and the decreased mortality of heart failure have resulted in an increased prevalence of heart failure. Incidence and mortality of systolic heart failure were higher than those of non-systolic heart failure.
