[Thrombolytic reperfusion of coronary arteries and the function of the left ventricle in acute myocardial infarction].

Left-ventricular myocardial contractility was assessed in thrombolytically-treated patients with acute myocardial infarction. General and local left-ventricular activity was shown to deteriorate progressively in patients with "late" or altogether absent recovery of coronary flow, whereas patients with early recovery of coronary flow demonstrated intact general contractility parameters and better contractility in the affected area. Coronary reperfusion within 5-6 hours helps to maintain functional capacity, which is less marked than the one in patients with early reperfusion.
