摘要
目的观察合并有糖尿病的冠心病者心脏变时性(CR)与心率变异性(HRV)的变化。方法选择经冠状动脉造影(CAG)确诊的30例合并有糖尿病的冠心病者(A组)和20例不合并糖尿病的单纯冠心病者(B组),行运动平板(TET)及24h动态心电图(DCG)检查,比较两组之间CR和HRV差别,并分析CR与HRV之间的相关性。结果 A组的心脏CR与HRV低于B组(P<0.05),CR和HRV的各项指标之间均有良好的相关性(P<0.01)。结论 A组CR与HRV比B组更低,提示合并有糖尿病的冠心病者心脏自主神经有明显功能紊乱。
Objective To study the chronotropic response(CR) and heart rate variability(HRV) in patients with coronary heart disease (CHD)complicated with diabetes mellitus(DM).Methods 30 patients with CHD complicated with DM(A group) and 20 patients with CHD(B group) without diabetes were selected.All subjects underwent treadmill exercise test and 24 hours dynamic electrocardiogram.Results All HRV indexes and CR indexes in Group A were lower than those in Group B (P<0.05 P<0.01).There were significant difference in the parameters of CR and HRV among the two groups(P<0.01).Conclusion In the patients with CHD complicated with DM,HRV and CR are lower than those in the patients with CHD ,suggesting obviously dysfunction of heart autonomic nerve of a coronary heart disease patient with diabetes mellitus.
