Abstract
Objective To investigate the correlation between deceleration capacity of rate(DC)and heart rate variability(HRV)in patients with type 2 diabetes mellitus complicated with acute myocardial infarction (T2DM+AMI).Methods A total of 30 cases of patients with T2DM+AMI in the hospital from March 2015 to March 2017 were selected as T2DM+AMI group,and 30 patients with T2DM only as T2DM group in the same period,and 30 healthy volunteers were selected as control group.DC,HRV and time domain index of three groups were recorded and analyzed.Results There were significant differences found between T 2DM group,T2DM+AMI group and control group in DC,rMSSD,PNN50%,SDANN and SDNN(P<0.05);DC, rMSSD,PNN50%,SDANN and SDNN of T2DM+AMI group were statistically lower than the T 2DM group (P<0.05).The incidence of DC lower than 4.5 ms in T2DM group and T2DM+AMI group were statistically higher than in the control group(P<0.05).And the incidence of DC lower than 4.5 ms in T2DM+AMI group were statistically higher than in the T 2DM group(χ2=3.744,P<0.05).The correlation analysis showed that DC were positively correlated with rMSSD,PNN50%,SDANN,SDNN(P<0.05)in T2DM group and T2DM+AMI group,respectively.Conclusion DC and HRV in patients with T2DM + AMI are significantly de-creased,and DC is positively correlated with the HRV time -domain index,and DC could quantitatively assess the vagus nerve tension in T2DM+AMI patients as an effective index reflecting the damage of the autonomic nervous system.关键词
