Abstract
This study aimed to assess the association of mid-regional (MR) pro-adrenomedullin (MR-proADM) and MR-pro-A-type natriuretic peptide (MR-proANP) in comparison to N-terminal pro-natriuretic peptide (NT-proBNP) with outcome in patients with aortic stenosis (AS) treated with transcatheter aortic valve implantation (TAVI). One hundred consecutive TAVI patients were included in this prospective study. Association of preinterventional levels of MR-proADM, MR-proANP, NT-proBNP, C-reactive protein (CrP), and high-sensitive cardiac Troponin T (hsTN) with 30-day and 1-year outcome was analyzed. There was no association with 30-day outcome, but all markers were associated with 1-year cardiovascular events and all-cause mortality. The combined biomarker analysis further improved risk prediction. In TAVI patients MR-proADM, MR-proANP, and NT-proBNP are promising predictors of adverse events within 1 year. Integration of these biomarkers into decision pathways may help to identify patients at higher risk.
