因冠状动脉急性闭塞导致的急性心肌梗死常出现ST段抬高,大量循证医学证明再灌注时间是决定这类患者预后的重要因素,目前指南要求接触患者的医务人员需在十分钟之内决定是否需要进行再灌注治疗,主要依据胸痛的临床表现和心电图出现ST段抬高作出判断〔1〕。除急性心肌梗死外,段抬高还见于多种情况,这些平时有段抬 Acute myocardial infarction due to acute coronary occlusion often presents with ST-segment elevation. Evidence-based medicine demonstrates that reperfusion time is an important factor in determining the prognosis of such patients. At present, the guidelines require that the medical staff who have been exposed to the patient decide within ten minutes Whether the need for reperfusion therapy, mainly based on the clinical manifestations of chest pain and ECG ST-segment elevation to determine 〔1〕. In addition to acute myocardial infarction, segment elevation is also seen in a variety of situations, these usually have some lift
