摘要:

目的 :探讨急性心肌梗死患者心率变异特征。方法:选择急诊心肌梗死患者190例，根据冠脉狭窄程度积分（Gensini评分）将其分为冠状动脉病变高分组、中分组、低分组。常规检测生化指标，进行24 h动态心电监测，记录心率变异性（HRV）指标，分析比较各组间HRV指标差异有无统计学意义，同时比较HRV与心肌梗死部位相关性。结果:HRV指标ASDNN、RMSSD、SDNN和SDANN，随着Gensini评分值升高而降低，低分组、中分组、高分组组间比较差异具有统计学意义（均P<0.05）；Pearson相关分析显示HRV指标ASDNN、RMSSD、SDNN和SDANN与Gensini评分值呈负相关（P<0.05）。与非前壁心肌梗死相比，前壁心肌梗死患者HRV指标ASDNN、RMSSD、SDANN和SDNN较低，差异有统计学意义（P<0.05）。结论:急性心肌梗死患者HRV各指标与冠状动脉病变程度及心肌梗死部位有相关性。

Abstract:

Objective: To explore features of heart rate variability in patients with acute myocardial infarction. Methods: One hundred and ninety patients with myocardial infarction who underwent coronary angiography were analyzed and divided into three groups by Gensini scoring: low group(n =62)，middle group(n =64)，high group(n =64)．All cases underwent 24 hour ambulatory electrocardiogram and their biochemical indicators were detected． Finally, the clinical information was analyzed and compared．Results: ASDNN,RMSSD,SDNN and SDANN indices tended to decrease with the extent and severity of coronary artery lesion，and showed statistical differences among low group，middle group and high group (P<0.05) .The index of HRV decreased as the severity of artery lesion increased (P<0.05).Anterior wall myocardial infarction had lower HRV in ASDNN,RMSSD SDNN and SDANN indices ( all P <0.05) than non-anterior wall myocardial infarction. Conclusion: The HRV may be related to the lesion degree of coronary artery and the location of myocardial infarction in patients with acute myocardial infarction.
