Background: The aim of the study was to investigate the prognostic value of selected biomarkers in patients with aortic regurgitation undergoing valve surgery.
Methods: A prospective study was conducted on a group of consecutive patients with hemodynamically significant aortic regurgitation that underwent elective aortic valve surgery. The primary endpoint was 30-day mortality and any major adverse event within 30 days.
Results: The study group included 205 consecutive patients who underwent replacement or repair of the aortic valve. The primary endpoint occurred in 72 patients. At multivariate analysis red cell distribution width (RDW; p = 0.03) and high-sensitivity troponin T (hs-TnT; p = 0.02) remained independent predictors of the major complications including death.
Conclusions: Elevated preoperative RDW and hs-TnT were associated with a poorer outcome following aortic valve surgery.
