风险评估是急性冠状动脉综合征管理的核心。然而，通常在肌钙蛋白浓度可用之前，评估是不完整的。采用2项多中心前瞻性观察性研究（急性冠状动脉事件方法和管理评估[EMMACE] 2，测试队列，1843例患者；EMMACE-1，验证队列，550例患者），对未选择的急性冠状动脉综合征患者进行入院风险分层，使用自动测量和年龄得出的正面QRS-T角度来预测30天和2年死亡率。额部QRS-T角度为104°的患者两年死亡率最低(44.7% vs 14.8%, p
Risk assessment is central to the management of acute coronary syndromes. Often, however, assessment is not complete until the troponin concentration is available. Using 2 multicenter prospective observational studies (Evaluation of Methods and Management of Acute Coronary Events [EMMACE] 2, test cohort, 1,843 patients; and EMMACE-1, validation cohort, 550 patients) of unselected patients with acute coronary syndromes, a point-of-admission risk stratification tool using frontal QRS-T angle derived from automated measurements and age for the prediction of 30-day and 2-year mortality was evaluated. Two-year mortality was lowest in patients with frontal QRS-T angles 104 degrees (44.7% vs 14.8%, p
