To study the relationship between clinical manifestations and coronary anatomy and morphology, coronary angiography was performed in 20 patients with chronic stable angina (Group I), in 18 patients with unstable angina (Group II), and in 20 patients with previous myocardial infarction (Group III). Although the site and extent of coronary artery disease were similar among the three groups, coronary morphology differed considerably, with a concentric lesion occurring in 70% of Group I patients and an eccentric lesion in 62% and 63% of Group II and Group III patients, respectively. The study suggests that coronary lesion morphology may form an anatomic basis in determining clinical manifestations for patients with coronary artery disease. An eccentric coronary stenosis may be useful in identifying high-risk patients. |
