Implication
HF incidence and short-term mortality rise sharply with age; leaves open whether contemporary therapies have altered outcomes in modern cohorts.
Key Points
- The aim is to analyze the long-term prevalence, incidence, and risk factors for heart failure in a general population sample.
- 34 years of follow-up data from the Framingham Study
- Analysis of incidence rates by age and sex
- Assessment of mortality rates post-heart failure diagnosis
- Heart failure prevalence is about 1% in individuals aged 50 and rises to 10% in those 80 and older.
- Annual incidence increases with age, from 0.2% in ages 45-54 to 4% in men 85-94 years.
- Male patients show higher risk due to coronary heart disease, leading to a fourfold increase in heart failure risk.

Outcome
Prevalence, incidence, secular trends, prognosis, and modifiable risk factors for the occurrence of heart failure
Heart failure is a highly prevalent and lethal condition in the general population, with incidence rising progressively with age and predominantly driven by hypertension and coronary disease.
