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 investigate the value of different shapes of ST segment elevation in predicting the extent of acute anterior myocardial infarction and left ventricular systolic function. Methods Totally 77 patients with acute anterior myocardial infarction (AMI) were divided into ST segment anterior descending group (bow back down group) 41 cases of high group (slope type group), 12 cases of ST segment dorsal elevation group (bow backwards group). Serum creatine kinase and left ventricular ejection fraction were measured and compared in three groups. Results Serum creatine kinase levels were (2 287.0 ± 1 001.2), (4 371.0 ± 2 541.2), (5 322.0 ± 3 219.6) u / L, 3 The difference between the two groups was statistically significant (P <0.05, P <0.01). The left ventricular ejection fraction on the 14th day after myocardial infarction were (58.8 ± 0.1)%, (48.1 ± 0.1)% and (41.0 ± 0.2) %, The difference between the three groups was statistically significant (P <0.05). Conclusion The different shapes of ST elevation in early stage of acute anterior myocardial infarction have some value in predicting infarct size and left ventricular function during reperfusion.
