| Abstract |
Introduction
Dyslipidemia impairs the cardiac autonomic activity (CAA) determined by heart rate variability (HRV) and aerobic capacity. However, both parameters were not measured in obese Thai subjects with dyslipidemia. Therefore we investigated resting heart rate variability and aerobic capacity in obese Thai subjects with dyslipidemia.
Methods
Twelve obese Thai subjects with dyslipidemia participated in this study. After overnight fasting, 3-min electrocardiographic (ECG) recording at rest was recorded by SA3000P (MEDICORE, South Korea). Then they perform graded exercise test to measure aerobic capacity on an electrically braked cycle ergometer (Corrival, Load, Netherlands). Aging progress of blood vessels was also determined by accelerated photoplethysmograph report (APG). Interpretation of HRV reference by HRV standard guideline.

Results and Discussion
Body weight was 71.53±9.37 kg. Body mass index (BMI) was 30.08±3.62 kg/m2. Total cholesterol was 209.67±28.45 mg/dL. Triglyceride was 172.25±69.13 mg/dL. LDL-c was 127.99±28.33 mg/dL. HDL-c was 49.92±18.47 mg/dL. Resting heart rate (HR) was 71±6.18 /min. Time domain of heart rate variability showed lower standard deviation of normal to normal R-R intervals (SDNN) (18.40, 30.58 ms., 16.7%,n=2), normal root mean square of successive heartbeat interval differences (RMSSDs) (27.90±9.96 ms., 100%,n=12). Frequency domain of heart rate variability showed lower total power (TP) (961.4±578.4 ms2, 58.3%,n=7), lower low frequency (LF) (2.38, 4.22 ms2, 16.67%,n=2), lower high frequency (HF) (3.57 ms2, 8.33%,n=1), and lower LF/HF ratio (0.304 ms2, 8.33%,n=1).The level of the aging progress of blood vessels of most subjects was level 3 (level 1 =16.67%, level 2= 16.67%, level 3 = 41.67% and level 4 = 25.00%). The aerobic capacity was 14.13±6.31 ml/kg/min.
Conclusion
The results demonstrate that obese Thai subjects with dyslipidemia had impaired heart rate variability (HRV) and aging progress of blood vessels. In addition, they had impaired aerobic capacity which is the strongest predictor of mortality among all risk factors for cardiovascular disease (CVD).
