[Nature of the correlation of the adrenergic reactions of the heart and coronary vessels in coronary circulatory disorder].

In acute experiments on dogs it was shown that under the conditions of a moderate (by 30 and 50%) decrease of the coronary blood flow, a quantitative and qualitative dissociations of changes in adrenergic reactions of the heart and coronary vessels to isadrin and noradrenaline occur--this was manifested by a distinct suppression of dilatational coronary reactions with a less pronounced suppression or even enhancement of adrenergic effects of the heart.
