We performed a prospective study by dual-channel ambulatory monitoring performed for 24 to 72 hours immediately after hospitalization for unstable angina. The incidence of ST-segment depression or elevation or ventricular tachycardia or complex premature ventricular complexes (PVCs) in 42 consecutive patients with unstable angina due to coronary artery disease (39 by coronary arteriography) was investigated. During ambulatory monitoring, 28 of 42 patients (67%) exhibited ST-segment depression or elevation, 13 of 42 patients (31%) had ventricular tachycardia or complex PVCs, and 31 of 42 patients (74%) had either ST-segment depression or elevation, ventricular tachycardia, or complex PVCs. Ventricular tachycardia or complex PVCs occurred in 10 of 20 patients (50%) with abnormal left ventricular function and in 3 of 22 patients (14%) with normal left ventricular function (p < 0.025). We found that 72 hours of ambulatory monitoring was not more useful than 48 hours in detecting the incidence of ST-segment depression or elevation, ventricular tachycardia, or complex PVCs. Ambulatory monitoring did not help in clinically differentiating patients with left main or 3-vessel disease from 1-vessel or 2-vessel disease. In addition, ambulatory monitoring did not help in predicting which patients with unstable angina would require coronary artery surgery.
