作者对心电图示正常、ST段压低≥0.5mm、T波倒置和既往左柬支传导阻滞(LBBB)的急性冠脉综合征(ACS)患者进行前瞻性研究。旨在探讨ACS患者的住院和4年死亡率及ST段压低≥0.5mm的预后意义。对象与方法研究对象为因静息性心绞痛住入冠心监护病房的ACS患者。平均年龄64±12岁。选择对象时已剔除ST段抬高型心肌梗死(MI)、新LBBB和非心源性胸痛患者。患者入院后24h内测定4次肌酸激酶。记录心电图。入院18h内发生下述2项者判为住院后MI:①典型缺血性胸痛≥30min;②
The authors prospectively studied patients with acute coronary syndrome (ACS) with normal ECG, ST-segment depression ≥ 0.5 mm, T-wave inversion, and previous LBBB. To investigate the ACS patients hospitalized and 4-year mortality and ST segment depression ≥ 0.5mm prognostic significance. Subjects and Methods Subjects were ACS patients admitted to coronary care unit due to resting angina. The average age of 64 ± 12 years old. Subjects were excluded from ST-segment elevation myocardial infarction (MI), new LBBB, and non-cardiac chest pain. Patients were admitted four days after the determination of creatine kinase 4 times. Record the cardiogram. Within 18h admitted to the following two were sentenced to hospitalized MI: ① typical ischemic chest pain ≥ 30min; ②
