The study examines long-term trends in the incidence of heart failure and survival rates among subjects in the Framingham Heart Study over a 50-year period from 1950 to 1999. The incidence of heart failure remained stable among men but declined by 31 to 40 percent among women. Survival rates after the onset of heart failure improved over time, with a 12 percent per decade reduction in mortality rates for both men and women. The study suggests that improvements in hypertension management and the increasing use of medications for heart failure have contributed to these trends. However, heart failure remains highly fatal, with over 50 percent of patients dying within five years of diagnosis. The findings highlight the need for continued efforts in primary prevention and better understanding of the underlying causes of heart failure.The study examines long-term trends in the incidence of heart failure and survival rates among subjects in the Framingham Heart Study over a 50-year period from 1950 to 1999.
