摘　　要：目的：探讨药物或手术干预对急性心肌梗死（AMI）与冠心病人心率变异性（HRV）的影响。方法：通过观察31例AMI患者药物治疗前后HRV改变及26例PICA术病人、25例CABG术病人手术干预性治疗前后HRV的改变。结果：三组病人的HRV指标在药物或手术干预后均有不同程度的改善，治疗后6个月趋稳定，但仍低于正常对照组。结论：心血管的干预性治疗可改善病人的HRV值，但该类病人仍存在交感迷走神经的平衡失调，故仍有潜在的危险性，而心肌梗死病人的潜在预后不良的危险性较PTCA及CABG组病人更大。The heart rate variability were ahalysis before and after clinical intervention in 31 AMI patients, 26 PTCA patients and 25 CABG patients. The results showed that HRV parameters were significantly lower in all patients before treatment and were greatly improvement after medical treatment, PTCA and CABG. However their HRV parameters were still lower than healtlry subjects. The result suggests that HRV did not fully recover after treatment of AMI and after PTCA and CABG. Low HRV predicted an adverse prognostics information.
