Hemodynamic effects of beta adrenergic receptor stimulant and blockade. Hemodynamic effects of isoproterenol after propranolol..
The effects of isoproterenol and propranolol on the hemodynamics were evaluated in dogs for the purpose of their clinical application in the management of cardiovascular surgical patients. In dogs receiving 0.002 mgjkg of isoproterenol intravenously with one shot, marked positive inotropic and chronotropic responses were achieved in 5 seconds and returned to the control values in 5 minutes. Hea...
متن کاملHemodynamic effects of acute and prolonged beta-adrenergic blockade in essential hypertension.
Absrract. Hemodynamic studies have been performed in 15 male patients with mild to moderately severe essential hypertension. Studies were made after four weeks of placebo treatment and again after acute i.v. administration of propranolol (0.22 mg/kg) and after four weeks of oral propranolol therapy (160-320 mg daily). After acute /3-adrenergic blockade a significant reduction of cardiac index (...
متن کاملImmediate hemodynamic effects of beta-adrenergic blockade with propranolol in normotensive and hypertensive man.
Immediate hemodynamic effects of beta-adrenergic blockade were determined in six normal subjects and 21 hypertensive patients following intravenous administration of propranolol. Arterial pressure was not reduced, but cardiac output fell by approximately 20% in both groups. Nevertheless, beta-adrenergic inhibition seemed to have different effects in the two groups: Propranolol produced a greate...
متن کاملHemodynamic and beta-adrenergic receptor adaptations during long-term beta-adrenoceptor blockade. Studies with acebutolol, atenolol, pindolol, and propranolol in hypertensive patients.
In an attempt to further clarify the mechanism of the maintenance of the antihypertensive effect of beta-adrenoceptor antagonists, the effects of four antagonists with different ancillary properties (acebutolol, atenolol, pindolol, and propranolol) on systemic and renal hemodynamics, body fluid volumes, hormones, and lymphocyte beta-adrenoceptor density were studied in four groups of 10 hyperte...
متن کاملBeta blockade in essential hypertension: an analysis of response to oxprenolol.
The data from 40 patients with essential hypertension treated with oxprenolol alone have been used to analyse the falls of blood pressure and heart rate. Blood pressure and heart rate did not fall further as the daily dose was increased above 160 mg. The range of fall in mean pressure was from 0 to 40 mmHg and there was no clear separation into response groups. Pressure falls were unrelated to ...
