Hemodynamic studies in experimental coronary occlusion: V. Changes in arterial blood pressure

1.1. Twenty-four hours after experimental occlusion of the left anterior descending coronary branch in dogs there occurs a decided fall in blood pressure which generally persists for at least one week.2.2. Twenty-four hours after ligation of left ventricular myocardium by the closed chest method a fall in blood pressure also occurs. This fall is smaller than that following the vascular occlusion.3.3. A comparison is made with control observations, and the mechanism for the decrease in blood pressure under these conditions is discussed.
