Short-term effect of percutaneous transluminal coronary angioplasty on contractile function of hibernating myocardium / 中国介入心脏病学杂志

ABSTRACT

Objective To investigate the short-term effect of PTCA on contractile function of hibernating myocardium. Methods Fifty-three patients with coronary heart disease and segmental dysfunction underwent echocardiography and radionuclide imaging. Echocardiography was repeated one week after PTCA. Results (1) Recovery of contractile function occurred in 87 revascularized segments with dysfunction (87/167, 52.1%) compared with only 2 nonrevascularized segments (2/59, 3.4%) (P
