Comparison of primary coronary angioplasty versus thrombolysis in patients with ST-segment elevation acute myocardial infarction and grade II and grade III myocardial ischemia on the enrollment electrocardiogram

摘要: Abstract We investigated the impact of primary angioplasty compared with thrombolysis in 894 patients ST elevation acute myocardial infarction and electrocardiographic grades II III ischemia on enrollment. Patients were divided into 2 groups based enrollment electrocardiogram—grade III: (1) absence an S wave below isoelectric baseline leads that usually have a terminal configuration (leads V 1 to 3 ), or (2) J-point amplitude ≥50% R-wave all other leads. To be included grade group, criteria ≥2 adjacent required. but without classified as having II. In-hospital mortality was 3.2% 6.8% (n = 616) 278) groups, respectively (p 0.016). In in-hospital similar subgroups (3.2% 3.3%, p=0.941). III, 6.4% 7.3%, 0.762). The odds ratio for group death 2.06 (95% confidence intervals [CI] 0.82 5.19; p=0.125); 2.30 CI 0.93 5.66; p=0.07). reinfarction occurred 3.3% 6.5% 0.137). 1.3% 4.4%, 0.239). Grade admission associated higher 30-day rate reinfarction. There no difference between patients.
