Abstract

Two hundred consecutive catheterized patients with unstable angina pectoris were reviewed to find clinical and noninvasive indicators of left main coronary artery disease (≥ 50% lesion). Thirty-five patients (17.5% of total) had left main coronary artery disease. There were no differences between patients with and without left main coronary artery disease in age, sex, results of resting electrocardiogram, congestive heart failure, dyspnea during pain, duration of longest pain, arrhythmias, response to medical therapy, or other factors. Crescendo angina pectoris (worsening of pre-existing angina), transient SY-segment depression with pain, simultaneous anterior and inferior ST changes during pain, and fluoroscopic calcification of the left main coronary artery were all significantly more common in patients with left main coronary artery disease. However, low sensitivity or low predictive value, or both, limit the usefulness of these clinical predictors. Left main coronary artery disease cannot be reliably predicted in patients with unstable angina pectoris before coronary arteriography.
