Evaluating Exercise Capacity and Heart Rate Recovery in Diabetic Type II Patients

Introduction: Type ۲ diabetes is a chronic disease with an increase in microvascular risks such as retinopathy and neuropathy. According to cardiac neuropathy in diabetic patients and the high prevalence of diabetes, the current study is designed to evaluate heart rate recovery and exercise capacity in diabetic versus healthy individuals. . Methods: This clinical study was performed on ۲۲۸ patients. The age, sex, weight, BMI, educational level, duration of disease, history of other medical disease and smoking, TG, LDL, CHOL, HDL, FBS, SBP, and DBP were listed in the checklist and were evaluated later. The SPSS software was used to analyze data statistically using t-test, Mann-Whitney, and Chi-Square tests. P>۰.۰۵ was considered significant.  Results: Mean Heart Rate Recovery, in the first mean, was ۱۶.۳۵ ± ۱۰.۵۶ in the study group and was ۲۵.۹ ± ۱۳ in the control group (P=۰.۰۰۱). The mean heart rate during rest in the study group was ۸۴.۳۹ ± ۱۳.۵ and in the control group was ۸۱.۴۴ ± ۱۴.۲۷ beat/min (P=۰.۱۱۰). The mean Heart Rate Reserve in the study group was ۴۸.۴۳ ± ۱۸.۸۷ and in the control group was ۵۷.۸ ± ۲۴.۱۷ (P=۰.۰۰۱). Negative Chronotropic Incompetence was seen in ۱۰ patients and ۱۹ healthy individuals (P=۰.۰۴۸).  Conclusion: According to our results and previous studies, heart rate recovery in diabetic patients is significantly less than in healthy individuals. The risk of cardiovascular disease in these patients is higher versus healthy individuals, and according to this fact, they need periodic visits.
