Abstract:
Objective To assess the changes of left ventricular function after off-pump coronary artery bypass (OPCAB) using Tei index. Methods Fourty-six patients of coronary artery disease, who had accepted OPCAB, were enrolled. Left ventricular ejection fraction(LVEF), E/A ratio at mitrial orifice(E/A), E deceleration time(EDT), isovolumic relaxation time(IVRT), ratio of systolic wave to diastolic wave of pulmonary vein flow(S/D) and Tei index were measured by transthoracic echocardiography before, immediate, 1 week, 1 month, 3 months and 6 months after OPCAB. Results Tei index decreased gradually as time went on after OPCAB and the differences were significant between different times(P
