Assessment the efficiency of percutaneus transluminal coronary angioplasty at patients with coronary disease using the heart rate variability and electrocardiogram dispersive charting

45 patients with coronary disease, subjected to planned stenting of coronary arteries, for assessment the efficiency of expeditious treatment are investigated the indicators of heart rate variability and dispersive charting of electrocardiogram before and after coronary angioplasty, and in half a year the clinical questioning is carried out. Correlation communications between the studied parameters and clinical-instrumental data of studied patients, including with failures in six-months period of observation are studied.
