冠脉造影对非ST段抬高型心肌梗塞的诊断价值

Diagnostic Value of Coronary Angiography in Non-ST-segment Elevation Myocardial Infarction

目的分析冠脉造影对非ST段抬高型心肌梗塞(Non-ST-Segment Elevation Myocardial Infarction,NSTEMI)的诊断价值。方法选取2016年1月至2018年12月海门市人民医院收治的42例NSTEMI患者进行研究,分别通过冠脉造影、常规心电图进行诊断,分析冠脉造影的诊断价值。结果ST段下移幅度≥1 mm三支/三支+左主干比例明显高于ST段下移幅度<1 mm,差异有统计学意义(P<0.05);ST段下移导联数≥6个三支/三支+左主干病变比例高于ST段下移导联数<6个,差异有统计学意义(P<0.05);QRS波时间≥100 ms三支/三支+左主干比例明显高于QRS波时限<100 ms,差异有统计学意义(P<0.05)。结论NSTEMI患者常规心电图表现不明显,具有一定的局限性。而冠脉造影病变大多表现为多支病变,可为临床诊断提供有效的参考。

Objective To analyze the diagnostic value of coronary angiography in patients with non-st-segment Elevation Myocardial Infarction(NSTEMI).Methods A total of 42 patients with NSTEMI admitted to Haimen People's Hospital from January 2016 to December 2018 were selected for the study.The diagnostic value of coronary angiography was analyzed by coronary angiography and routine electrocardiogram.Results The percentage of three branches/three branches+left main trunk in ST segment was significantly higher than that of ST segment<1 mm,and the difference was statistically significant(P<0.05).The number of ST segment descending leads≥6 and the proportion of 3 leads/3 leads+left main disease was higher than that of ST segment descending leads<6,the difference was statistically significant(P<0.05).The proportion of three branches/three branches+left main trunk with QRS time≥100 ms was significantly higher than that with QRS time<100 ms,and the difference was statistically significant(P<0.05).Conclusion Routine ecg of NSTEMI patients was not significant and had some limitations.However,most coronary angiography lesions are multi-vessel lesions,which can provide effective reference for clinical diagnosis and is worthy of promotion and application.
