Despite the successes of modern cardiology, disability and mortality from cardiovascular pathologies are currently increasing, mainly due to patients with acute myocardial infarction. Changes in heart rate variability in patients with acute myocardial infarction (AMI) according to echocardiography were studied. The study included 45 men aged 18 to 45 years (39.2 ± 2.5 years) who were admitted to the cardiac intensive care unit with a diagnosis of ACS with further transformation into AMI with a wave (25 bx) or without a Q wave ( 20 b -X). Correlation analysis data suggests that timely diagnosis of patients with ST- elevation ACS allows initiating timely and appropriate treatment, which improves the prognosis of cardiovascular diseases and reduces the risk of developing cardiovascular catastrophes.
