The effect of selective coronary angiography on the amount of the coronary blood flow is discussed. The effect of sublingual nitroglycerin administration on the level of the coronary flow was also studied. The coronary flow was measured with the aid of intracoronary injection of Xe133 prior to selective coronary angiography, and on the 3rd, 6th and 10th minutes following the termination of the radiocontrast examination. The coronary blood flow was shown either to remain unchanged, or to decrease slightly on the 3rd minute after the termination of angiography, as compared with the value of this parameter prior to the examination. On the 6th minute some increase of the coronary flow is observed, on the average 12%, which subsequently returns to the initial level. Sublingual intake of nitroglycerin results in an increase of the coronary flow, both prior to and following coronary angiography.
