Segmental evaluation of left ventricular wall motion after myocardial infarction: magnetic resonance imaging versus echocardiography.

abstract：BACKGROUND:Few data are available concerning the effects on clinical outcome and left ventricular function of abciximab administration in patients undergoing rescue percutaneous transluminal coronary angioplasty (PTCA) after failed thrombolysis for acute myocardial infarction. The aim of the study was to investigate su...
