[Coronary arteriography in coronary heart diseases with angina pectoris (an analysis of 55 cases)].
A retrospective study of the coronary arteriographic findings in 55 cases with angina pectoris, 10 spontaneous angina and 45 effort angina (unstable angina 21, stable 24) was presented in the present article. Among the 10 cases with spontaneous angina, 8 showed normal coronary arteries, 2 with double vessel disease. In the 45 cases with effort angina, single and multiple vessel disease was found in 9/45 (20%) and 33/45 (73.3%) respectively, the remaining 3/45 (6.7%) were normal. There was no significant difference in severity and distribution of coronary atherosclerotic lesion (P greater than 0.05) in the two subgroups of unstable and stable angina. However in 3 out of 21 cases (14%) with unstable angina total occlusion of coronary arteries was found suggesting the presence of intracoronary thrombus. Triple vessel disease or/and left main coronary artery lesion was observed more frequently in cases with unstable angina (13/21, 61.9%) than in cases with stable angina (10/24, 41.7%).
