摘要: Abstract The prevalence and characteristics of silent myocardial ischemia as detected by 24-hour ambulatory electrocardiography ST-segment depression were prospectively assessed in 94 patients examined early (1 to 3 months) 184 late (12 after coronary artery bypass grafting (CABG), followed for a mean 48 ± 11 (range 4 62) months. relation electrocardiographic evidence completeness revascularization defined cardiac angiography performed 1 12 months CABG, prognosis follow-up adverse clinical events was analyzed. Silent 20% (19 94) 27% (50 184) patients, showed frequency episodes ranging from 6 10 episodes/24 hours with duration 15 23 minutes. circadian distribution disclosed significant peak ischemic activity during the period A.M. noon secondary between P.M. midnight (p
