[Features of the clinical and functional state of myocardial infarction patients with psychogenic silent ischemia].
A total of 111 patients with myocardial infarction were studied in the early, period of the disease. Exercise and information load tests, impedance plethysmography, electrocardiography, and large-framed fluorography were performed. Among the patients with myocardial infarction who responded to information load by exhibiting transient silent ischemia, vasospastic reactions were demonstrated to be diagnosed mainly in those with posterior myocardial infarction. The patients with anterior myocardial infarction responded to psychoemotional stress mainly by showing ischemia formed under the conditions of higher myocardial oxygen uptake due to increased blood minute volume. In most patients, the area of silent psychogenic vasospastic ischemia coincided with that of infarct-related myocardium, whereas ischemic changes were largely located in the anterior left ventricular wall despite the area of myocardial necrosis when psychogenic ischemia developed with increased myocardial oxygen uptake.
