Heart failure (HF) is reported to have an essentially malignant prognosis that can be modified by several interventions. Most outcome data on HF are available from randomized controlled treatment trials and longitudinal epidemiological studies. However, for a number of reasons, neither type of study have, to date, provided generalizable data on HF mortality. Furthermore, data on the prognosis of borderline left ventricular systolic dysfunction (LVSD) are even more limited.
