BACKGROUND: The clinical impact of coronary artery disease (cad) on the prognosis of patients undergoing mitraclip implantation is still unclear. METHODS: One thousand nine hundred fifty-three patients undergoing MitraClip implantation included in the multicenter GIOTTO Registry were stratified according to CAD. Endpoints were all-cause death, cardiac death, and re-hospitalization for heart failure at follow-up (median 15.8 months). RESULTS: Although younger, CAD patients were more symptomatic, had worse cardiovascular risk profile, higher burden of comorbidities, more frequently affected by functional mr, with higher left ventricle (LV) diameters and lower ejection fraction (eF). at follow-up, cad patients showed higher rates of all-cause death (25.4% vs. 19.6%; P=0.002), cardiovascular death (14.0% vs. 10.1%; P=0.007) and re-hospitalization for heart failure (13.9% vs. 10.2%; P=0.011). dividing the population according to mitral regurgitation (mr) etiology (functional vs. nonfunctional mr), no differences were observed between cad and no-cad patients. at multivariate logistic regression, NYHa iii/iV class, prior heart failure hospitalization, severe chronic kidney disease, atrial fibrillation, LV end-diastolic diameter and LVEF<30% but not CAD resulted independent predictors of all-cause death. The same finding was confirmed even after propensity score adjustment. cONcLUSiONS: cad did not show a relevant impact on mid-term prognosis per se, but seemed to identify a more complex and diseased cohort of patients with worse clinical and functional status.

Abstract
BACKGROUND: The clinical impact of coronary artery disease (cad) on the prognosis of patients undergoing mitraclip implantation is still unclear. METHODS: One thousand nine hundred fifty-three patients undergoing MitraClip implantation included in the multicenter GIOTTO Registry were stratified according to CAD. Endpoints were all-cause death, cardiac death, and re-hospitalization for heart failure at follow-up (median 15.8 months). RESULTS: Although younger, CAD patients were more symptomatic, had worse cardiovascular risk profile, higher burden of comorbidities, more frequently affected by functional mr, with higher left ventricle (LV) diameters and lower ejection fraction (eF). at follow-up, cad patients showed higher rates of all-cause death (25.4% vs. 19.6%; P=0.002), cardiovascular death (14.0% vs. 10.1%; P=0.007) and re-hospitalization for heart failure (13.9% vs. 10.2%; P=0.011). dividing the population according to mitral regurgitation (mr) etiology (functional vs. nonfunctional mr), no differences were observed between cad and no-cad patients. at multivariate logistic regression, NYHa iii/iV class, prior heart failure hospitalization, severe chronic kidney disease, atrial fibrillation, LV end-diastolic diameter and LVEF<30% but not CAD resulted independent predictors of all-cause death.
