Prognostic Value of NT-ProBNP in Patients with Primary Mitral Regurgitation Undergoing Transcatheter Edge-To-Edge Repair
Main finding · Death or HF hospitalizationResult — go to the resultAdjusted hazard ratio 1.17 95% CI 1.07–1.28Authors' conclusion
NT-proBNP, but not the MIDA score, was independently associated with death or heart failure hospitalizations within 3 years in M-TEER-treated PMR patients.
