Prognostic value of exercise stress echocardiography in patients with secondary mitral regurgitation: a long-term follow-up study

Secondary mitral regurgitation (MR) remains a challenging problem in the diagnosis and treatment of patients with heart failure. Although it is well known that secondary MR is dynamic, the impact of the severity of MR during exercise on long-term outcome has not been fully evaluated. The aim of the present study was to investigate the prognostic value of exercise stress echocardiography (ESE) in patients with secondary MR. This prospective study...
