摘要
目的探讨急性心肌梗死(acute myocardial infarction,AMI)患者心率减速力(deceleration capacity of rate,DC)及连续心率减速力(heart rate deceleration runs,DRs)对急性心肌梗死猝死的预警价值。方法选取2014年1月至2016年12月在本院住院的116例AMI患者,其中ST段抬高性心肌梗死(STEMI)74例,非ST段抬高性心肌梗死(NSTEMI)42例,对照组为本院同期体检中年龄、性别相匹配的健康体检者110例,均进行24小时动态心电图(Holter)检查,分别测定DC值、DRs值及心率震荡(HRT)、心率变异性(HRV)值,并进行相关性分析。结果 AMI组DC值及DR4、DR8明显小于对照组,差异有显著性(P<0.01);DC、DRs预测中、高危患者的比例在AMI组为45.68%,明显高于对照组的8.18%,差异有显著性(P<0.01);AMI组的DC、DRs与HRT、HRV呈正相关;STEMI和NSTEMI患者中高危患者比例无明显差异(P>0.05)。结论 DC、DRs值能有效评价患者自主神经功能状态,筛选出AMI患者猝死的高危人群,预警室性快速心律失常及心源性猝死,对AMI患者预后评价具有良好的临床参考价值。
Objective To study the clinical significance and its early warning value of ventricular tachycardia between deceleration capacity of heart rate（DC） and heart rate deceleration runs（DRs） in patients who with acute myocardial infarction（AMI）. Method One hundred and sixteen patients with AMI, of which ST-segment elevation myocardial infarction（STEMI） 74 cases, non-ST-segment elevation myocardial infarction（NSTEMI） in 42 cases,and one hundred and ten control subjects served as the study population. They were examined by 24 hours holter monitoring. DC, DRs, heart rate turbulence（HRT）, heart rate variability（HRV） were collected and do correlation analysis. Result The values of DC, DR4, DR8 were lower in AMI group than in control group（P〈0.01）. The proportion of 42.24% in the AMI group patients at media-high risk was significantly higher than that in control group 8.18%（〈P0.01）; There was no significant difference in the proportion of high-risk patients between STEMI and NSTEMI, with no significant difference between the two groups（P〉0.05）. Conclusion DC and DRs values can effectively evaluate the autonomic nervous function status of patients, screening out high-risk groups of sudden death in patients with AMI.
