| 中文摘要:目的 研究分析急性心肌梗死(AMI)患者的心率减速力(DC)与连续心率减速力(DRs)指标对于其短期预后的影响作用。方法 选取四川大学华西医院心血管内科收治的确诊AMI患者180例(AMI组)和体检健康研究对象100例(健康组),对两组进行24h动态心电图监测,比较分析两组的DC、DRs值差异,并观察不同DC、DRs危险分层的AMI患者6个月内出现不良心血管事件的发生率差异。结果 AMI组患者的DC、DR2、DR4、DR8的测定值均显著的小于健康组且差异均具有统计学意义(P<0.05)。AMI组患者的中高风险比例(45.00%)显著的高于健康组的(11.00%)且差异均具有统计学意义(P<0.05)。AMI组低风险患者的左心室舒张末期内径(LVEDD)显著的低于中、高风险AMI患者(P<0.05),低风险患者的左心室射血分数(LVEF%)显著的高于中、高风险患者(P<0.05)。高风险的AMI患者的心源性病死率(18.18%)、严重心力衰竭发生率(36.36%)、心律失常率(40.91%)、再发心绞痛/心肌梗死率(50.00%)均显著的高于中、低风险的AMI患者(P<0.05)。结论 AMI患者的DC与DRs指标较正常人群发生显著的改变,同时根据其风险分层可以对患者的预后情况进行预测。 |

| Abstract:Objective To study the deceleration capacity of rate (DC) and Heart Rate deceleration runs (DRs) on the short-term prognosis of acute myocardial infarction (AMI) patients. Methods Totally 180 patients (AMI group) and 100 healthy subjects (healthy group) were selected from the Department of Internal Medicine in West China Hospital, Sichuan University, 24h ECG (AMI group), two DRs and 6 DRs in the two groups were compared. Results The DC, DR2, DR4, DR8 of P<0.05 group were significantly less than that of the healthy group and the difference was statistically significant (AMI). The high risk ratio (45%) of the P<0.05 group was significantly higher than that of the healthy group (11%) and the difference was statistically significant (AMI). The left ventricular end diastolic diameter (LVEDD) of the patients with low risk in the AMI group was significantly lower than that in the patients with high risk AMI (P<0.05), and the left ventricular ejection fraction (LVEF%) was significantly higher in patients with low-risk patients (P<0.05). The risk of cardiac death (18.18%), severe heart failure (36.36%), arrhythmia (40.91%), recurrent angina and myocardial infarction (50.00%) were significantly higher in patients with high risk AMI (P<0.05). Conclusion DC and DRs in patients with AMI were significantly changed compared with the normal population, and according to the risk stratification can predict the prognosis of patients. |
