[Study of the effect of the restoration of coronary blood flow on left-ventricular contractility in patients with acute myocardial infarction based on the data of computerized two-dimensional echocardiography].
Total and local left-ventricular contractility was assessed by computerized two-dimensional echocardiography in 52 patients with acute myocardial infarction. Three groups of patients were identified: those with recovered coronary flow (group 1), reperfusion failure (group 2) and the lack of occlusion at first coronarography (group 3). Patients from group 3 showed the most intact left-ventricular myocardial contractility and the most favorable clinical course of the disease, while second-group patients had particularly impaired left-ventricular contractility. In the first group, the size of the asynergic area diminished by day 28 of the disease to a greater extent, as compared to the second group. Therefore, coronary reperfusion within the first 6 hours after the attack shows correlation to a smaller asynergic zone and a more favorable clinical course of the disease.
