Clinical Efficacy of Ningxin Tongluo Decoction(宁心通络汤)Combined with Dapagliflozin on Patients of Type 2 Diabetes Mellitus Complicated with Ventricular Premature Beats

Objective:To explore the clinical efficacy of Ningxin Tongluo Decoction(宁心通络汤)combined with Dapagliflozin in the treatment of type 2 diabetes mellitus complicated with ventricular premature beats.Methods:Ninety-two patients with type 2 diabetes mellitus complicated with ventricular premature beats in our hospital were randomly divided into control group(n=46)and observation group(n=46).The control group was treated with routine Western medicine,and the observation group was treated with Ningxin Tongluo Decoction on the basis of the control group.The clinical efficacy of the two groups before and after treatment,TCM syndrome score,blood glucose levels[fasting blood glucose(GLU),glycosylated hemoglobin(Hb A1c)],glucose metabolism levels[fasting insulin(FINS),insulin resistance index(HOMA-IR)],the number of ventricular premature beats detected by 24-hour ambulatory electrocardiogram,heart rate turbulence(HRT)[initial oscillation(TO),oscillation slope(TS)],and heart rate variability(HRV)standard deviation of two normal R-R intervals(SDNN),standard deviation of average normal R-R intervals every 5 minutes(SDANN)and root mean square of adjacent normal R-R intervals(RMSSD)were observed.Results:After treatment,the total effective rate of the observation group was 89.13%,significantly higher than that of the control group(73.91%),and the difference was statistically significant(P<0.05).Both groups could reduce TCM syndrome score,blood glucose level,glucose metabolism level,reduce the number of ventricular premature beats,improve HRT and HRV levels,and the observation group was superior to the control group,and the difference was statistically significant(P<0.05).Conclusion:Ningxin Tongluo Decoction combined with Dapagliflozin is effective in treating type 2 diabetes mellitus patients with ventricular premature beats.It can reduce blood glucose level,improve HRV and HRT,improve autonomic nerve function and exert antiarrhythmic effect.
