[Newly occurring stenocardia: the clinical picture, diagnosis, treatment and prognosis]

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.
