| Abstract: | In 44 consecutive patients with angina at rest associated with transient S-T segment elevation, clinical features were correlated with angiographic coronary anatomy. Patients were divided into three groups depending on the number of major vessels having ?70 per cent luminal narrowing: Group I = no or minimal disease (six patients); group II = single vessel disease (13 patients); and group III = multiple vessel disease (25 patients).The following features did not differ significantly among groups I, II or III: age, sex, risk factors, time from onset of episodes of pain at rest to study or arrhythmias during ischemic episodes. Patients in group III were more likely to have angina on effort (p < 0.001) and an abnormal base line electrocardiogram (p < 0.001) than patients in groups I or II. However, the absence of these features did not separate patients in group I from those in group II.In patients with angina at rest associated with transient S-T segment elevation, clinical features identify patients with multiple vessel disease but do not allow differentiation of patients with no or minimal coronary disease from patients with single vessel disease. |
