[Effect of furanthril on several hemodynamic indices during the acute stage of myocardial infarction]

Pulmonary arterial pressure, heart rate and peripheral arterial pressure were followed up by the 15th, 45th and 105th minute post intravenous introduction of 40 mg furanthril in patients with myocardial infarction in acute stage (in 42 cases of 12 patients with left cardiac insufficiency and in 14 cases--of 8 patients without cardiac insufficiency). Furanthril induced clearly manifested pressure decrease in the pulmonary artery in patients with left cardiac insufficiency, developing between the 15th and 45th minute and continuing till the end of the second hour and a negligible elevation of peripheral arterial pressure by the 15th minute, followed by a slight decrease of the latter under the initial value by the 45th and 105th minute. Similar tendency, but less manifested, exists and in patients without cardiac insufficiency. Heart rate is kept unchanged. Furanthril does not induce undesirable hypotonic states when applied in those doses in patients who, as a rule, arenot hyptonics.
