目的:分析急性冠脉综合征中不稳定型心绞痛及急性非ST段抬高心肌梗死患者体表心电图缺血性J波与心脏事件的关系及对预后的价值。方法:选择我院2006年6月—2010年6月根据WHO制定的标准诊断为不稳定型心绞痛及急性非ST段抬高心肌梗死者116例。按照心电图是否记录到J波分为两组,A组(60例)和B组(56例)。随访终点比较两组发生心脏事件的比例。结果:A组患者24h动态心电图室速、室颤发生率与B组比较差异有统计学意义(P<0.05)。经过6~60个月随访,A组58例完成随访,发生心脏事件28例;B组抵达随访终点46例,发生心脏事件9例。A组发生心脏事件发生率与B组比较差异有统计学意义(P<0.05)。结论:伴有缺血性J波的非ST段抬高型急性ACS者预后不良。
OBJECTIVE: To analyze the relationship between ECG-induced ischemic J wave and cardiac events in patients with unstable angina pectoris and acute non-ST segment elevation myocardial infarction in patients with acute coronary syndrome and its prognostic value. Methods: A total of 116 patients with unstable angina pectoris and acute non-ST segment elevation myocardial infarction diagnosed in our hospital from June 2006 to June 2010 were selected. According to whether ECG recorded J waves into two groups, A group (60 cases) and B group (56 cases). At the end of follow-up, the proportions of cardiac events in both groups were compared. Results: The incidence of ventricular tachycardia and ventricular fibrillation in group A was significantly higher than that in group B (P <0.05). After 6 to 60 months of follow-up, 58 patients in group A were followed up and 28 cases had cardiac events. In group B, 46 patients reached the end of follow-up and 9 patients had cardiac events. The incidence of cardiac events in group A was significantly different from that in group B (P <0.05). Conclusions: The prognosis is poor in non-ST-elevation acute ACS with ischemic J waves.
