Abstract
BackgroundTricuspid regurgitation (TR), prevalent in acute heart failure (AHF), has a poor prognosis; however, the dynamics of TR severity during hospitalization and its prognostic implications remain unclear. We investigated TR dynamism during hospitalization and its prognostic impact in AHF. Methods and ResultsThis is a post hoc analysis of a prospective multicenter study of patients with AHF who underwent echocardiographic TR severity evaluation at admission and before discharge. The primary end point was a combined of 1-year all-cause mortality and HF rehospitalization after discharge. Among 1079 participants, TR severity changed dynamically, with 60.3% of those with moderate TR and 29.6% of those with severe TR at admission being diagnosed as no or mild TR at discharge. In 3 groups stratified by changes in TR severity, the persistent TR groups had a higher incidence of the primary end point than the resolution and absence groups. In adjusted analyses, the persistent group (hazard ratio, 1.37; 95% confidence interval, 1.04–1.80), but not the resolution group (hazard ratio, 1.07; 95% confidence interval, 0.79–1.44), had a higher primary end point incidence than the absence group. ConclusionsTR severity at admission in patients with AHF can change dynamically and is associated with subsequent prognosis. Significant TR that remains even after decongestive therapy might be a target for further treatment in hospitalized patients with AHF.
