Abstract
Exercise may induce ventricular arrhythmias (VA) in patients with coronary artery disease. Exercise-induced VA can identify a subset of patients at higher risk of cardiac sudden death. The role of myocardial ischaemic and/or left ventricular disease in the appearance of VA during exercise is not completely understood. The incidence of VA during exercise-induced myocardial ischaemia was investigated in patients with suspected CAD or those undergoing a stress exercise test after a previous myocardial infarction (MI). Patients were divided in four groups. Group A, 836 patients without a previous MI showing exercise-induced myocardial ischaemia associated with ST-segment depression - group B, 72 patients without a previous MI and exercise-induced ST-segment elevation - group C, 50 patients survivors of a recent (1 month) MI and exercise-induced ST-segment depression - group D, 580 patients with an old MI (> 3 months) and a positive exercise test associated with ST-segment depression. Exercise-induced VA were found to be significantly more frequent in patients of groups C (40.0%) and B (23.6%) as compared with groups A (5.1%) and D (7.06%) (P
