[Hemodynamic indices assessed by impedance cardiography in patients with the subacute stage of myocardial infarct before and during bicycle ergometry].
The hemodynamic indices were determined in 51 patients with myocardial infarction, subacute stage, before and after bicycle ergometric loading. The following indices were determined by impedance cardiography: cardiac output, total peripheral resistance, volume velocity of blood ejection, power of cardiac contractions, index of myocardial contractility etc. The results reveal that the patients with subacute stage of myocardial infarction have reduced reserve possibility of blood circulation apparatus. Signs of latent cardiac failure are manifested in case of extensive localization with transmural involvement, because of seven disorders in the contractile function of myocardium. The adaptation to physical loading, in the rest of the patients, is better but still far less than that in healthy subjects.
