Abstract:
Objective To explore the relevance between resting heart rate (RHR) and metabolic syndrome in young and middle-aged patients with essential hypertension.Methods Three hundred and forty patients with essential hypertension were enrolled in this study.According to the RHR,the hypertension patients were categorized into 3 groups:group RHR 1 (RHR ＜ 70 bpm,52 cases),group RHR 2(RHR 70-85 bpm,168 cases) and group RHR 3 (RHR ＞ 85 bpm,120 cases).The RHR,blood pressure,fasting blood glucose,triglyceride,high density lipoprotein cholesterol,2 h postprandial blood glucose and waistline were determined and compared.Results The level of fasting blood glucose,2 h postprandial blood glucose,triglyceride,waistline,systolic pressure,diastolic pressure,and high density lipoprotein cholesterol in group RHR 1 were (4.96 ± 0.65) mmol/L,(6.85 ± 0.51) mmol/L,(1.69 ± 0.43) mmol/L,(78.3 ± 6.5) cm,(143.2 ± 5.6) mmHg (1 mmHg=0.133 kPa),(85.4 ±5.2) mmHg and (1.08 ±0.64) mmol/L.In group RHR 2 they were (5.66 ± 0.77) mmol/L,(7.94 ± 0.66) mmol/L,(2.58 ± 0.75) mmol/L,(88.6 ± 7.3) cm,(156.7 ± 6.1) mmHg,(93.6 ± 4.7) mmHg,and (0.95 ± 0.59) mmol/L.In group RHR 3 they were (6.85 ± 0.73) mmol/L,(8.97 ± 0.59) mmo]/L,(3.52 ± 0.90) mmol/L,(95.8 ± 9.2) cm,(164.3 ± 7.4) mmHg,(101.2 ± 3.5) mmHg and (0.78 ± 0.33) mmol/L.With the increase of RHR,the level of fasting blood glucose,2 h postprandial blood glucose,triglyceride,waistline,systolic pressure and diastolic pressure increased step by step,high density lipoprotein cholesterol decreased step by step,and there were significant differences (P ＜ 0.05).Correlation analysis showed that RHR was positively correlated with fasting blood glucose,2 h postprandia blood glucose,triglyceride and waistline (r =0.52,0.45,0.50,0.36,P ＜ 0.05),and negatively correlated with high density lipoprotein cholesterol(r =-0.39,P ＜ 0.05).Conclusion RHR is closely related to the metabolic disorder in young and middle-aged patients with essential hypertension,and doctors should pay attention to the heart rate control while lowering blood pressure.
