Abstract Objective To explore the effects of PCI on sinus heart rate turbulence in patients with unstable angina pectoris (UAP) complicated with type 2 diabetes mellitus. Methods A total of 110 patients with UAP complicated with type 2 diabetes mellitus were selected,then were divided into 57 cases in the observation group and 53 cases in the control group. The two groups were given conventional treatment of UAP and diabetes. Among all the patients,dynamic electrocardiogram was done to calculate turbulence onset (TO) and turbulence slope (TS) before treatment and one month after treatment. Results TO was significantly lower and TS was significantly higher in the observation group at one month after PCI(P < 0.05). Compared with the control group at one month after PCI,TO was significantly lower and TS was significantly higher in the observation group(P < 0.05). TO was significantly lower and TS was significantly higher in multi-vessel group compared with that of single-vessel group(P < 0.05). Conclusion PCI can more effectively improve HRT in patients with UAP complicated with type 2 diabetes mellitus. Patients should undergo PCI therapy to improve the long-term prognosis.
