Mizutani K, et al. - In this multicenter prospective observational study, researchers examined the 2-year prognostic impact of N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels at discharge following transcatheter aortic valve implantation (TAVI) by analyzing data of 500 consecutive patients who had TAVI with measurements of NT-proBNP at discharge between 2013 and 2016. The findings from the present study suggested that elevation of NT-proBNP at discharge was related to higher incidence of the 2-year composite endpoint (all-cause mortality and heart failure hospitalization) after TAVI.
