Haemodynamic advantages of combined alpha-blockade and beta-blockade over beta-blockade alone in patients with coronary heart disease.
The acute haemodynamic effects of beta-blockade with propranolol and combined alpha-blockade and beta-blockade with labetalol were compared in a randomised study in 12 patients with coronary artery disease proved by angiography. Propranolol induced significantly greater depression of left ventricular function both at rest and during exercise than labetalol. This difference was probably attribut...
متن کاملComparative haemodynamic dose response effects of propranolol and labetalol in coronary heart disease.
The immediate haemodynamic dose response effects of beta blockade (propranolol: 2 to 16 mg) were compared with those of combined alpha beta blockade (labetalol: 10 to 80 mg) in a randomised study of 20 patients with stable angina pectoris. After control measurements, the circulatory changes induced by four logarithmically cumulative intravenous boluses of each drug in equivalent beta blocking d...
متن کاملBeta-blockade in the management of chronic heart failure. Another step in the conceptual evolution of a neurohormonal model of the disease.
Although heart failure has been viewed primarily as a haemodynamic disorder, the development of pharmacologic agents that address the haemodynamic derangements has not proved to be a successful approach to its management. Consequently, attention in recent years has shifted to the development of neurohormonal antagonists in the hope that prolonged interference with the renin-angiotensin system a...
متن کاملInfluence of selective and non-selective beta-adrenoreceptor blockade on the haemodynamic effect of adrenaline during combined antihypertensive drug therapy.
1. Haemodynamic effects of adrenaline were studied in 27 hypertensive patients, succesively during treatment with propranol and metoprolol. In 12 patients beta-adrenoreceptor blockade was combined with diuretics and in 15 patients the blockade was combined with vasodilators. 2. During propranolol adrenaline caused a marked pressor effect: there was a considerable rise in systolic as well as in ...
متن کاملBeta-adrenergic blockade and the metabolic response to surgery.
The effect of the administration of propranolol 0.15 mg per kg body weight i.v. on the metabolic response to pelvic surgery was compared with results in similar patients who had not received propranolol. The only significant difference between the two groups was a lower plasma insulin concentration in the beta-blockade patients after 60 and 90 min of surgery. The glycaemic response to surgery w...
