Health status, exercise capacity help predict outcomes in heart failure with mitral regurgitation

Reuters Health - 03/09/2021 - In patients with heart failure (HF) and severe secondary mitral regurgitation, disease-specific health status and exercise capacity provide complementary information that's useful for prognosis, researchers have found. This prognostic information is valuable both before and after transcatheter mitral-valve replacement (TMVr), as well as if a patient receives medical treatment only, they note in JACC: Heart Failure. "At baseline, health status is more closely associated with risk of HF hospitalization, whereas exercise capacity is a stronger predictor of late mortality," Dr. Suzanne V. Arnold of Saint Luke's Mid America Heart Institute, in Kansas City, Missouri, and colleagues report. "While improvements in both measures are associated with better outcomes over time, health status may be a better assessment of response to treatment with TMVr, given its increased sensitivity to change," they say. The study was a secondary an...
