Abstract

140 patients with coronary artery disease were submitted to Holter monitorization and cardiac catheterization, and the data from each method were analysed and compared with each other. The mean age of our patients was 53.7 years, with a male predominance at 3:1. Unstable angina was more common when all three vessels were diseased, and only 5% of these patients did not have angina. The greatest risk factor was cigarette smoking; all patients with arrhythmias had at least one risk factor. The resting ECG detected serious arrhythmias in only 1.4% of our patients compared with 31% detected by Holter. In the hemodynamic data, the left ventricular end diastolic pressure, the cardiac index and collaterals did not help in differentiating patients with and those without arrhythmias. On the other hand, left ventricular impairment in the IV angiogram and a lower ejection fraction were important in indicating patients with serious arrhythmias. Dyskinesias was specially discriminative being present in 6.3% of patients with normal Holter and in 34.9% of patients with serious arrhythmias. Follow-up data is briefly presented showing that the development of sudden death is more prevalent in individuals with serious arrhythmias.
