Angiographic morphology in unstable angina pectoris.

Published

Journal Article

Complex morphology occurs frequently in unstable angina; however, its relation to symptomatic presentation, timing of angiography and hospital outcome has not been investigated. Accordingly, coronary angiography was performed 5 +/- 2 days after qualifying rest pain in 101 consecutive patients presenting with acute coronary insufficiency (n = 67) or crescendo angina (n = 34). Significant coronary artery disease was defined as any greater than or equal to 50% stenosis, and complex morphology as any stenosis with irregularity, overhang or thrombus. Eight of the 67 patients presenting with acute coronary insufficiency later proved to have a myocardial infarction as the qualifying event (creatine kinase twice normal with elevation of MB fraction). There were no myocardial infarctions in the crescendo angina group. Complex morphology occurred in 61% of patients. Thrombus alone occurred in 27% of patients with unstable angina without myocardial infarction, with similar frequencies between the 2 clinical groups. In contrast, intraluminal thrombi were identified in 78% of patients with acute coronary insufficiency who later proved to have a myocardial infarction as the qualifying event. The need for urgent catheterization (less than 48 hours) prompted by recurrent symptoms was associated with the angiographic findings of intraluminal thrombus (46%) and complex morphology (83%). The presence of complex morphology and intracoronary thrombus was associated with a higher incidence of in-hospital cardiac events, i.e., revascularization, myocardial infarction and death, independent of the incidence of multivessel disease.
