摘要
目的观察ST段抬高的不同形状在预测急性前壁心肌梗死范围及左心室收缩功能中的价值。方法 77例首发急性前壁心肌梗死患者根据其再灌注前V3导联ST段抬高的形状分为ST段弓背向下抬高组(弓背向下组)24例,ST段斜坡型抬高组(斜坡型组)41例,ST段弓背向上抬高组(弓背向上组)12例。检测并比较3组患者血清肌酸激酶和左室射血分数。结果弓背向下组、斜坡型组、弓背向上组血清肌酸激酶水平分别为(2 287.0±1 001.2),(4 371.0±2 541.2),(5 322.0±3 219.6)u/L,3组间比较差异有统计学意义(P<0.05,P<0.01);心肌梗死后第14天左室射血分数分别为(58.8±0.1)%,(48.1±0.1)%,(41.0±0.2)%,3组间比较差异有统计学意义(P<0.05)。结论急性前壁心肌梗死早期ST段抬高的形状不同对再灌注患者恢复期梗死范围及左室功能的预测有一定价值。
Objective To study the value of ST-segment elevation pattern to predicting infarct size and left ventricular systolic function in patients with acute anterior myocardial infarction. Methods Seventy seven patients with first-episode acute anterior myocardial infarction （AAMI） before reperfusion were divided into 3 groups according to the ST segment elevation pattern in lead V3： concave type （n= 24）, straight type （n 41） and convex type （n = 12）. The serum creatine phosphate kinase （CK） and left ventricular ejection fraction （LVEF） were measured. Results The CK level was （2 287.0±1 001.2） u/L, （4 371.0±2 541.2） u/L and （5 322.0±3 219.6） u/L in concave type, straight type and convex type, which showed significant differences in these three types （P〈0.05, P〈0.01）. By day 14 after myocardial infarction, LVEF was （58. 8±0. 1）G, （48. 1±0. 1）%, and （41. 0±0. 2）%, which showed significant differences in these three types （P〈0.01）. Conclusion The ST-segment elevation pattern in early stage of acute anterior myocardial infarction is useful for predicting myocardial infarction area and left ventrieular function.
