- Abstract
Background: Frailty and heart failure share pathophysiology and clinical characteristics., Objectives: The aim of this study was to analyze the contribution of heart failure to the physical frailty phenotype by examining patients with heart failure before and after percutaneous mitral valve repair (PMVR)., Methods: Frailty according to the Fried criteria (weight loss, weakness, exhaustion, slowness, and low activity) was assessed in consecutive patients before and 6 weeks after PMVR., Results: A total of 118 of 258 patients (45.7%) (mean age: 78 ± 9 years, 42% female, 55% with secondary mitral regurgitation) were frail at baseline, which significantly decreased to 74 patients (28.7 %) at follow-up (P < 0.001). The frequency of frailty domains slowness, exhaustion, and inactivity significantly decreased, whereas weakness remained unchanged. Baseline frailty was significantly associated with comorbidities, N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels, and functional capacity, whereas frailty after PMVR was not associated with NT-proBNP levels. Predictors of postprocedural reversibility of frailty were NYHA functional class
