Echocardiographic characteristics including tissue Doppler imaging after enhanced external counterpulsation therapy.
This study assessed the effects of a course of enhanced external counterpulsation (EECP) therapy on systolic and diastolic cardiac function using echocardiography to measure left ventricular ejection fraction (LVEF), end-systolic volume (ESV), end-diastolic volume (EDV), systolic wave (Sm), early diastolic wave (Ea), Vp, E/Ea, E/Vp, and diastolic function grade in 25 patients before and after 35 hours of EECP. EECP reduced ESV and EDV and increased ejection fraction significantly in patients with baseline LVEF or = 14 (P=.032, .038, .007), baseline grade II or III diastolic dysfunction (decreased compliance) (P=.014, .032, .027), baseline Ea 50, baseline E/Ea or = 7 cm/s, and Sm > or = 7 cm/s. These results demonstrate improved systolic and diastolic function in selected patients and provide new insight into potential clinical applications of EECP
