目的:探讨急性ST段抬高型心肌梗死(STEMI)与非ST段抬高型急性冠状动脉综合征(NSTE-ACS)临床特征及冠状动脉病变特点。方法:146名行急诊冠脉介入治疗(PCI)患者分为STEMI组(112名)和NSTE-ACS组(34名)。观察两组患者基线临床特点及冠脉病变特征。结果:两组患者的性别、年龄、住院时间、既往病史、差异均无统计学意义。冠心病危险因素中吸烟史STEMI组较NSTE-ACS组有增多趋势(P=0.076)。STEMI组白细胞较NSTE-ACS组明显升高(P=0.041)。冠脉病变STEMI组罪犯血管为左回旋支(LCX)的显著少于NSTE-ACS组,但右冠状动脉(RCA)的更多见(P=0.011),STEMI组造影发现血栓显著多于NSTE-ACS组(P=0.014)。两组在其余病变特点差异均无显著性。结论:STEMI患者较NSTE-ACS更多伴有吸烟史,入院时白细胞更高,LCX的显著少于NSTE-ACS组,RCA的更多。行急诊PCI时STEMI组造影血栓更多见。
Objective: To investigate the clinical features of acute ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation acute coronary syndrome (NSTE-ACS) and the characteristics of coronary lesions. Methods: A total of 146 patients undergoing emergency PCI were divided into STEMI group (n = 112) and NSTE-ACS group (n = 34). Baseline clinical characteristics and coronary lesion characteristics of the two groups were observed. Results: There was no significant difference in gender, age, hospitalization time, past medical history and difference between the two groups. There was an increasing trend of smoking history among coronary heart disease risk factors compared with NSTE-ACS group (P = 0.076). The number of leukocytes in STEMI group was significantly higher than that in NSTE-ACS group (P = 0.041). In the coronary artery disease group, the culprit vessels in the STEMI group were significantly less than those in the NSTE-ACS group in the left circumflex artery (LCX), but were more common in the right coronary artery (RCA) (P = 0.011) ACS group (P = 0.014). There was no significant difference between the two groups in the characteristics of the other lesions. CONCLUSIONS: Compared with NSTE-ACS, STEMI patients are more likely to have smoking history, higher leukocyte admission, significantly less LCX than NSTE-ACS group, and more RCA. STEMI group emergency thromboembolism thrombosis more common.
