Diastolic Heart Function and Myocardial Electrical Instability in Patients with Q-wave Myocardial Infarction

The study included 131 male patients between the ages of 30 and 69 (51.99.13 years) with primary Q-wave myocardial infarction (Q-MI). All patients underwent clinical examination, including a physical examination, medical history, ECG in 12 conventional leads, echocardiography, and 24-hour ECG monitoring from the 10 th to the 14 th day of MI. The progression of left ventricular diastolic dysfunction in Q-MI patients is associated with a longer history of coronary heart disease and arterial hypertension. With worsening diastolic dysfunction, a marked decrease in LV systolic function is revealed. The severe diastolic dysfunction in Q-MI patients is closely associated with myocardial electrical instability. (Int
