摘要
目的探讨非ST段抬高急性心肌梗死(non-ST-segment elevation acute myocardial infarction,NSTEAMI)的临床特点及治疗现状。方法回顾分析我院急性心肌梗死300例的临床资料,根据心电图有或无ST段抬高分为两组,对比分析其临床特点和治疗情况。结果NSTEAMI病人的发病年龄大、女性比例高、静息性胸痛和心律失常的发生率低(P<0.01);NSTEAMI病人血中肌钙蛋白I阳性率、肌钙蛋白T、肌酸激酶、肌酸激酶同工酶的水平低(P<0.01或P<0.05);两组病人冠状动脉病变的Gensini评分、单支、双支和多支病变之间的差异无统计学意义(P>0.05);NSTEAMI病人接受血运重建和抗血小板药物的比例低(P<0.01)。结论NSTEAMI病人发病年龄大,女性比例高,胸痛和心律失常发生率低,血中心肌损伤标记物水平低,冠状动脉病变程度与ST段抬高急性心肌梗死病人差异无统计学意义。
Objectives To study the clinical features and treatments of non-ST-segment elevation acute myocardial infarction （NSTEAMI） . Methods Three hundred patients with acute myocardial infarction were divided into two groups according to the ST-segment of electrocardiogram. Retrospective analyses were made between two groups. Results Compared with ST-segment elevation acute myocardial infarction （STEAMI） group, there were more female in NSTEAMI group and the patients were older （P〈0.01） . Patients with NSTEAMI were less likely to have chest pain and arrhythmia （P〈0.01） . The positive rate of cardiac troponin I and levels of cardiac tropenin T, creatine kinase and creatine kinase-MB were low in NSTEAMI group （P〈 0.01 or P〈0.05） . Both groups had the same changes in coronary arteries （P〉0.05） . Patients in NSTEAMI group were less likely to be given revascularization and anticoagulation drugs （P〈0.01） . Conclusions NSTEAMI patients are older and more females. Compared with STEAMI group, patients with NSTEAMI have fewer symptoms, lower levels of myocardial infarction markers. The degrees of coronary artery stenosis of the two groups are the same.
