The goal of studies was to define diagnostic possibilities of echocardiography. 1250 patients with myocardial infarction and aggravations of ischemia were examined in the conditions of resuscitation and intensive care unit. The application of echoCG gives the possibility to determine with great accuracy the state of transport function of myocardium, pinpoint a location of cardiac muscle affection and measure its gravity, make a diagnosis of myocardial infarct aggravations at an early period, control the efficiency of treatment which is provided.

The report presents the results of EchoCG study in 81 patients with unstable stenocardia admitted in 6-24 hours from the onslaught pain. With the help of EchoCG the myocardial contractile function was defined and the segmental kinetics of left ventricular wall was registered with respect to four variants of unstable stenocardia courses: stenocardia occurred for the first time, progressive stenocardia, variational stenocardia and postmyocardial infarction stenocardia. During the EchoCG examination at the moment of anginal attack the significant increase in left ventricular end-diastolic volume and end-systolic volume and decrease of total ejection fraction were noted. Also, not infrequently the zones of dyskinesia are recorded indicative of ischemia of these segments, which commonly have transient character. With the progress of myocardial ischemia the abnormalities of left ventricular diastolic fraction appear which are determined with the help of Doppler-EchoCG. Thus, the use of EchoCG in diagnostics of patients with unstable stenocardia allows more reliably to define the degree of myocardial changes.

The article analyses the results of treatment of 77 patients with primarily emerged stenocardia. Three variants of clinical course of illness were distinguished: primarily emerged stenocardia at the state of exertion, primarily emerged progressive stenocardia at the state of exertion, primarily emerged stenocardia at rest state. As for primarily emerged stenocardia at the state of exertion, the changes at the final part of QRS complex were disclosed in 56% of patients, and abnormalities in the mobility of the left ventricle walls in 32%. The contractive function of left ventricle was unchanged. The myocardial infarction developed in 8% of patients in the course of one month, and in 4% in the course of one year. Stenocardia attacks disappeared in 16% of patients. As for primarily emerged progressive stenocardia, the ECG changes were marked in 74% of cases. The whole sphygmic fraction in 65% of patients was 55% lower. The myocardial infarction developed in 12% of patients in the course of one month and in 10.7% in more remote period. 52% of patients with the primarily emerged stenocardia at rest had ECG changes. In ECG daily monitoring 33% of patients had characteristic changes of coronary artery spasm. Myocardial infarction occurred in 8% of patients in the course of the first year. Stenocardia attacks disappeared in 25% of patients.
