Usefulness of ST-segment changes in ≥2 leads on the emergency room electrocardiogram in either unstable angina pectoris or non-Q-wave myocardial infarction in predicting outcome

摘要: Abstract To determine the reliability of admission electrocardiogram in predicting outcome patients hospitalized for chest pain at rest, 90 were randomized into a trial aspirin versus heparin unstable angina or non-Q-wave myocardial infarction, and prospectively followed 3 months. The emergency room was analyzed ST-segment deviation ≥1 mm/lead T-wave changes. Unfavorable outcomes recurrent ischemic pain, infarction coronary revascularization with angioplasty surgery. In who underwent arteriography, myocardium jeopardy score ranging from 0 to 10 assigned, based on number vessels diameter stenosis ≥70% location stenoses. Considering all patients, an ≥2 leads had positive predictive value adverse clinical events 79% negative 64%. subset without left ventricular hypertrophy whose electrocardiograms recorded during (62 90), ST improved 89% 72%.
