N2 - Introduction and objectives: Heart failure mortality is similar to or even higher than that due to various cancers. It is usually associated with disease progression, though sudden death has also been reported as a frequent cause of mortality. The objectives of this study were to investigate mortality and its causes in outpatients with heart failure of different etiologies who were treated in a specialist multidisciplinary unit, and to identify associated factors. Methods: The follow-up cohort study (median duration 36 months) involved 960 patients (70.9% male; median age 69 years; ejection fraction 31%; and the majority had an ischemic etiology and were in functional class II or III). Results: Overall, 351 deaths (36.5%) occurred: 230 due to cardiovascular causes (65.5%), mainly heart failure (33.2%) and sudden death (16%); 94 due to non-cardiovascular causes (26.8%), mainly malignancies (10.5%) and septic processes (6.8%); and 27 (7.7%) due to unknown causes. Mortality was independently associated with age, sex, functional class, ejection fraction, time since symptom onset, ischemic etiology, diabetes, creatinine clearance rate, peripheral vascular disease, fragility, and the absence of treatment with an angiotensin-converting enzyme inhibitor or angiotensin-II receptor blocker, betablockers, statins or antiplatelet agents. The principal factor associated with cardiovascular death was an ischemic etiology. No factor studied clearly predicted sudden death. Conclusions: Even though mortality in patients treated at a specialist heart failure unit was not low, a quarter died from non-cardiovascular causes. The principal factor associated with cardiovascular death was an ischemic etiology. Only 5.8% of the study population experienced sudden death.
