Effects of Ca2+ desensitizing green tea extract catechin on cardiac function in cardiomyopathy patients with diastolic dysfunction. Various cardiac functions have been measured using echocardiography in cardiomyopathy patients before (t0) and after (t6 or t12) catechin treatment: (a) left ventricular end systolic dimension (LVESD); (b) left ventricular end diastolic dimension (LVEDD); (c) left ventricular end systolic volume (LVESV); (d) left ventricular end diastolic volume (LVEDV); (e) stroke volume (SV); (f) ejection fraction (EF); (g) mitral Doppler E/A wave ratio (E/A ratio); (h) isovolumetric relaxation time (IVRT). t0, before the administration of catechin; t6, 6 months after the administration of catechin; t12, 12 months after administration of catechin. * P < 0.05, t6 vs t0; ** P < 0.05, t12 vs t0
