Prognostic Significance of the Initial Electrocardiographic Pattern in a First Acute Anterior Wall Myocardial Infarction

摘要: The availability of potent, but potentially dangerous, types reperfusion therapy for acute myocardial infarction (AMI) has forced us to refine our tools early and accurate diagnosis risk stratification patients with evolving AMI. estimation be made shortly after admission, when only the history, physical examination, ECG are available. This study was undertaken compare in-hospital mortality different patterns obtained at admission in 147 consecutive an first AMI anterior wall. By using a new classification ECG, it possible divide into 3 groups: (1) group A contained 12 tall peaked T waves involved leads, without ST segment elevation; (2) B comprised 77 abnormal elevation, major changes terminal portion QRS complex; (3) C 58 waves, distortion QRS. 0, percent, 29 percent groups A, B, C, respectively (χ 2 = 22.91; p 3=0). logistic regression model, found that initial pattern alone is strong predictor wall predicted probabilities death 0.0016, 0.025, 0.29, respectively. simple may enable differentiation low (groups B) those almost 30 (group C).
