Abstract Propranolol may offer an approach to the treatment of anginal pain which is refractory to conventional modes of therapy. Its efficacy may result from (1) lowering both left ventricular mechanical and metabolic requirements, (2) interference with sensory perception of anginal pain, or (3) blockade of adrenergic coronary vasoconstrictor activity which may precipitate angina in some subjects. Neither clinical nor resting physiologic data seem to be of value in predicting the response of a given patient to the drug.
