Prognostic value of mitral regurgitation assessment during exercise echocardiography in patients with left ventricular dysfunction: A follow-up study of 1.7 ± 1.5 years †

摘要

Aims The value of exercise echocardiography (EE) over resting echocardiography when this last incorporates information on mitral regurgitation (MR) is only partially known. Furthermore, limited data exist regarding the value of MR worsening during exercise in patients with left ventricular (LV) dysfunction. We investigate whether EE has incremental value over a resting echo-Doppler study; and whether post-exercise MR increments the value of EE for predicting outcome in patients with LV dysfunction.
