title: [Coronary angiographic characteristics of patients with unstable angina].
abstract: In order to study the characteristics of coronary lesions of patients with unstable angina, coronary angiograms and clinical manifestations were analysed on 388 patients. The results were as follows: single vessele disease was more common in new onset effort angina (69.64%) than in other groups (P < 0.05). Triple vessele disease and left main coronary artery lesion appeared more frequently in patients with rest angina than in other groups (72.34% and 27.66% respectively, P < 0.05), so did complex lesions and type C lesions (36.07% and 60.64% respectively, P < 0.05). More than half of the culprit lesions in early postinfarction angina was subtotal or total occlusions (53.12%), being more frequently found in this than in other groups (P < 0.05). Most of the patients with Prinzmetal variant angina had mild coronary lesions only. Coronary thrombi were found in 10.45% of the 388 patients; they were was more frequent in patients with early postinfarction angina (20.00%) than in the groups of new onset effort angina, aggravated effort angina and Prinzmetal variant angina (4.26%, 7.53% and 0% respectively, P < 0.05). Coronary thrombi were also more frequent in the patients with chest pain at rest (16.39%) than in the groups of new onset effort angina and Prinzmetal variant angina (P < 0.05). It is suggested that patients with angina at rest should be treated more intensively. Strengthened anticoagulation treatment should be given to patients with early postinfarction angina and angina at rest.
