    Abstract:
    BACKGROUND: We lack recent data on the incidence, correlates, and prognosis associated with heart failure (HF) development in patients with stable coronary artery disease (CAD). Here, we analyzed HF development in a contemporary population of outpatients with stable CAD. METHODS AND RESULTS: Of 4184 unselected outpatients with stable CAD (ie, myocardial infarction [MI] and/or coronary revascularization >1 year earlier) included in the multicenter CORONOR registry, we identified 3871 patients with no history of hospitalization for HF at inclusion and followed 3785 (98%) of them for 5 years. During follow-up, 211 patients were hospitalized for HF (5-year cumulative incidence 5.7%) and 163 patients had incident MIs. Independent predictors of hospitalization for HF were older age, lower left ventricular ejection fraction (LVEF), atrial fibrillation, higher body mass index, diabetes mellitus, history of hypertension, angina at inclusion, and multivessel CAD. Most hospitalizations for HF (62.6%) occurred in patients with LVEF ≥50% at inclusion, and most (92.4%) were not preceded by an incident MI. Hospitalization for HF was a powerful predictor of mortality (adjusted hazard ratio 5.97, 95% confidence interval 4.55-7.83; P < .0001). After hospitalization for HF, mortality rates were similar in patients with LVEFs ≥50% and <50% at hospitalization. CONCLUSIONS: Outpatients with stable CAD were frequently hospitalized for HF, and HF was associated with high mortality. Most HF hospitalizations were associated with preserved LVEF at inclusion and were not preceded by an incident MI.
