our results suggest that : a ) coronary artery thrombosis is frequent in evolving myocardial infarction b ) selective intracoronary thrombolysis and subsequent reperfusion of the infarcted area is readily obtainable with urokinase infusion c ) no significant acute modifications of left ventricular function were observed d ) 2-3 weeks after initial treatment , patients in which recanalization of an occluded vessel was achieved ( group a1 ) and patients that presented with subocclusive stenosis and reduced blood flow ( group b ) , showed an improvement in left ventricular function and a reduction in the akinetic area .
