Abstract
To obtain further information on the mechanism by which catecholamines produce myocardial ischemia, the effects of propranolol on metabolic and mechanical responses to adrenaline or noradrenaline were investigated in coronary-constricted dogs. Propranolol suppressed the myocardial ischemia produced by noradrenaline and adrenaline in dogs with moderate coronary constriction.
