IncidenCe and predictOrs of heaRt fAiLure after acute coronarY Syndrome: The CORALYS registry

Background: Previous studies investigating predictors of Heart Failure (HF) after acute coronary syndrome (ACS) were mostly conducted during fibrinolytic era or restricted to baseline characteristics and diagnoses prior to admission. We assessed the incidence and predictors of HF hospitalizations among patients treated with percutaneous coronary intervention (PCI) for ACS. Methods and results: CORALYS is a multicenter, retrospective, observational registry including consecutive patients treated with PCI for ACS. Patients with known history of HF or reduced left ventricular ejection fraction (LVEF) were excluded. Incidence of HF hospitalizations was the primary endpoint. The composite of HF hospitalization or cardiovascular death, and cardiovascular and all-cause death were the secondary endpoints. Predictors of HF hospitalizations and the impact of HF hospitalization on cardiovascular and all-cause death were assessed by means of multivariable Cox proportional hazards model.14699 patients were included. After 2.9 ± 1.8 years, the incidence of HF hospitalizations was 12.7%. Multivariable analysis identified age, diabetes, chronic kidney disease, previous myocardial infarction, atrial fibrillation, pulmonary disease, GRACE risk-score ≥ 141, peripheral artery disease, cardiogenic shock at admission and LVEF ≤40% as independently associated with HF hospitalizations. Complete revascularization was associated with a lower risk of HF (HR 0.46,95%CI 0.39-0.55). HF hospitalization was associated with higher risk of CV and all-cause death (HR 1.89,95%CI 1.5-2.39 and HR 1.85,95%CI 1.6-2.14, respectively). Conclusions: Incidence of HF hospitalizations among patients treated with PCI for ACS is not negligible and is associated with detrimental impact on patients' prognosis. Several variables may help to assess the risk of HF after ACS

Impact of Complete Revascularization on Development of Heart Failure in Patients With Acute Coronary Syndrome and Multivessel Disease: A Subanalysis of the CORALYS Registry

Background The impact of complete revascularization (CR) on the development of heart failure (HF) in patients with acute coronary syndrome and multivessel coronary artery disease undergoing percutaneous coronary intervention remains to be elucidated. Methods and Results Consecutive patients with acute coronary syndrome with multivessel coronary artery disease from the CORALYS (Incidence and Predictors of Heart Failure After Acute Coronary Syndrome) registry were included. Incidence of first hospitalization for HF or cardiovascular death was the primary end point. Patients were stratified according to completeness of coronary revascularization. Of 14 699 patients in the CORALYS registry, 5054 presented with multivessel disease. One thousand four hundred seventy‐three (29.2%) underwent CR, while 3581 (70.8%) did not. Over 5 years follow‐up, CR was associated with a reduced incidence of the primary end point (adjusted hazard ratio [HR], 0.66 [95% CI, 0.51–0.85]), first HF hospitalization (adjusted HR, 0.67 [95% CI, 0.49–0.90]) along with all‐cause death and cardiovascular death alone (adjusted HR, 0.74 [95% CI, 0.56–0.97] and HR, 0.56 [95% CI, 0.38–0.84], respectively). The results were consistent in the propensity‐score matching population and in inverse probability treatment weighting analysis. The benefit of CR was consistent across acute coronary syndrome presentations (HR, 0.59 [95% CI, 0.39–0.89] for ST‐segment elevation myocardial infarction and HR, 0.71 [95% CI, 0.50–0.99] for non‐ST‐elevation acute coronary syndrome) and in patients with left ventricular ejection fraction >40% (HR, 0.52 [95% CI, 0.37–0.72]), while no benefit was observed in patients with left ventricular ejection fraction ≤40% (HR, 0.77 [95% CI, 0.37–1.10], P for interaction 0.04). Conclusions CR after acute coronary syndrome reduced the risk of first hospitalization for HF and cardiovascular death, as well as first HF hospitalization, and cardiovascular and overall death both in patients with ST‐segment elevation myocardial infarction and non‐ST‐elevation acute coronary syndrome.
