Objective To study the relationship between resting heart rate and blood lipid level.Methods A total of 9 415 subjects aged≥40 years were included in the present study.Their resting heart rate was monitored and their serum levels of triglyceride(TG),total cholesterol(TC),low density lipoprotein cholesterol(LDL-C)and high density lipoprotein cholesterol(HDL-C)were measured to define dyslipidemia according to the 2007 Chinese Guidelines on Prevention and Treatment of Dyslipidemia in Adults.Results The subjects were divided into group A with their resting heart rate<70 beats/min,group B with their resting heart rate=70-79 beats/min,group C with their resting heart rate=80-89 beats/min,and group D with their resting heart rate≥90 beats/min.High TG,TC,and LDL-C were presented across the resting heart rate(Ptrend<0.01).Multiple logistic regression analysis revealed that the risk of high TG and TC was higher in subjects with their resting heart rate≥90 beats/min than in those with their resting heart rate<70 beats/min(OR=1.42;95%CI:1.16-1.74 and OR=1.33;95%CI:1.09-1.64,respectively).Conclusion Elevated resting heart rate is associated with high TG and TC in middle-aged and elderly Chinese subjects.
Objective To study the relationship between resting heart rate and blood lipid level. Methods A total of 9 415 subjects aged> 40 years were included in the present study. Resting heart rate was monitored and their serum levels of triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (HDL-C) and high density lipoprotein cholesterol (HDL-C) were measured to define dyslipidemia according to the 2007 Chinese Guidelines on Prevention and Treatment of Dyslipidemia in Adults. Results The subjects were divided into group A with their resting heart rate <70 beats / min, group B with their resting heart rate = 70-79 beats / min, group C with their resting heart rate = 80-89 beats / min, and group D with their resting heart rate Multiple logistic regression analysis revealed that the risk of high TG and TC was higher in subjects with their resting heart rate (Ptrend <0.01) ≥90 beats / min than in those with their resting heart rate <70 beats / min (OR = 1.42; 95% CI: 1.16-1.74 and OR = 1.33; 95% CI: 1.09-1.64, respectively) .Conclusion Elevated resting heart rate is associated with high TG and TC in middle -aged and elderly Chinese subjects.
