Background: Coronary revascularization is common in heart failure (HF). Aims: Clinical characteristic and assessment of in-hospital and long-term outcomes in patients hospitalized for HF with or without a previous percutaneous coronary intervention (PCI) or a coronary artery bypass grafting (CABG). Methods: The primary endpoint (PE) (all-cause death) and the secondary endpoint (SE) (all-cause death or hospitalization for HF-worsening) were assessed at one-year in 649 inpatients of the ESC-HF Pilot Survey. Additionally, occurrence of death during index hospitalization was evaluated. Results: PCI/CABG-patients (32.7%) were more frequently male, smokers, had myocardial infarction, hypertension (HT), peripheral artery disease and diabetes. The non-PCI/CABG-patients more often had a cardiogenic shock and died in-hospital. The PE occurred in 33 of the 212 PCI/CABG-patients (15.6%) and in 56 of the 437 non-PCI/CABG-patients (12.8%; P=0.3). The SE occurred in 82 of the 170 PCI/CABG-patients (48.2%) and in 122 of the 346 non-PCI/CABG-patients (35.3%; P=0.01). Independent predictors of the PE in the PCI/CABG-patients were: lower left ventricular ejection fraction, use of antiplatelets; in the non-PCI/CABG-patients were: age, ACS at admission. Independent predictors of the SE in the PCI/CABG-patients were: diabetes, NYHA (New York Heart Association) class at admission, HT; in the non-PCI/CABG-patients were: NYHA class, haemoglobin at admission. Serum sodium concentration at admission was a predictor of the PE and the SE in both groups. Heart rate at discharge was a predictor of the PE and the SE in the non-PCI/CABG patients. Conclusions: The revascularized HF patients had a similar mortality and higher risk of death or hospitalizations at 12 months compared with the non-PCI/CABG-patients. The revascularized patients had more comorbidities, while the non-PCI/CABG-patients had a higher incidence of cardiogenic shock and in-hospital mortality.
