The relationship of resting heart rate and dyslipidemia in the elderly / 中国基层医药

ABSTRACT

Objective To investigate the relationship of resting heart rate (RHR)and dyslipidemia in the elderly.Methods 3 919 cases of cerebrovascular disease risk factor screening in Renqiu permanent residents aged 60 -70 years were selected,excepted cases of atrial fibrillation and hyperthyreosis and received lipid -lowering and slowing the heart rate drugs as the research subjects,mean age 64(62,67)years,the rates of male and femal were 44.0% and 56.0% respectively.They underwent face -to -face health questionnaire,blood pressure and RHR meas-urement,anthropometric and laboratory tests.According to the RHR,they were divided into four groupsRHR160 times/min and 70 times/min and 80 times/min.The effect of RHR on dyslipidemia was analyzed by multivariate logistic regression analysis.Results The high TC,TG,and the prevalence of high LDL -C increased gradually with heart rate,the differences were statisti-cally significant (all P <0.001).The prevalence low HDL -C and HDL -C levels had no obvious statistically differ-ences.TC,TG,and LDL -C and RHR were positively correlated.RHR1<60 times/min was set as control group,the correction of gender,age,smoking,drinking,lack of physical activities,hypertension,diabetes,coronary heart disease, stroke or TIA,overweight,abdominal obesity,systolic pressure,diastolic blood pressure,fasting plasma glucose,insu-lin,uric acid,high TC in 60 -70 times/min,70 -80 times/min,and the risk of more than 80 times/min,respectively (OR =1.304,95%CI0.983 -1.73),(OR =1.579,95%CI1.195 -2.088),(OR =1.677,95%CI1.258 -2.237).Conclusion The RHR and the prevalence of dyslipidemia is related,medical workers need to know the rela-tionship between RHR and dyslipidemia,increase the focus on RHR and intervention,in order to effectively control the occurrence of dyslipidemia and cardio -cerebrovascular disease,especially cholesterol heighten.
