[Effect of the use of lidocaine on patients with acute myocardial infarct].

In 411 patients with acute myocardial infarction (AMI) the effect of intravenous lidocaineeee administration was studied in a suboptimal dose - under 1,5 mg/min (to 1979) and in the optimal dose - over 1,5 mg/min, minimum 2 mg/min during the first 12 hours, with an average 24 h dose, 3,0 g in the course of 48 hours. The patients were grouped into three prognostic groups, depending on their initial assessment according to the coronaryprognostic index of M. R.

[Urinary catecholamine excretion and cardiac output in hypertensive patients].

Cardiac output was determined to 70 patients with hypertonic disease I, II and III stage by dye-dilution method and urine excretion of adrenaline and noradrenaline was determined by fluorescence method. The extent of stroke and minute volume was determined depending on the stage of the disease, degree of arterial hypertension and patients' age. Noradrenaline excretion was normal in 75.

[Clinical and hemodynamic characteristics of the decompensation syndrome in patients with congestive cardiomyopathy].

Thirty seven patients were clinically and hemodynamically studied under hospital conditions. The stage of cardiomegaly, the stasis in the pulmonary and systemic circulations were followed up as well as the presence of manifestations of pulse deficit, incidence of gallop rhythm manifestation. It was established that in the patients with II-A stage of decompensation of circulation, a decreased cardiac output was found, enhanced peripheral resistance and normovolemia.
