Insights
Hypertension significantly reduces heart rate variability, even without diabetes. Adding type 2 diabetes does not further decrease heart rate variability in hypertensive patients.
Area of Science:
- Cardiology
- Diabetology
- Hypertension Research
Introductions:
Heart rate variability is reduced among patients with hypertension and/or with diabetes mellitus. Hypertension and diabetes show frequent co-morbidity, but it is still not entirely clear whether heart rate variability is reduced in non-diabetic patients with hypertension.
Aim:
The aim of the authors was to evaluate the heart rate variability in hypertensive patients with and without diabetes and in control subjects.
Method:
130 patients with hypertension, 48 patients with hypertension and type 2 diabetes mellitus, and 87 control subjects were involved in the study. Minimum, mean and maximum heart rate, and parameters of heart rate variability were measured.
Results:
The mean of minimum heart rate did not differ significantly between the three groups. However, all other parameters were significantly reduced in patients with hypertension with and without diabetes as compared to the control group. No significant differences were observed between hypertensive patients with and without diabetes mellitus.
Conclusions:
Heart rate variability is significantly reduced in non-diabetic patients with hypertension. It seems that type 2 diabetes results in no further significant reduction of heart rate variability in patients with hypertension.
