Abstract:
Objective:To investigate the association of cumulative resting heart rate(cumRHR)exposure with cardi-ovascular disease(CVD)risk and accumulation of cardiovascular risk factors in the elderly.Methods:This prospec-tive study enrolled 336 elderly physical examinees from Cangzhou People's Hospital between March and October 2016.Resting heart rate(RHR)measured by electrocardiogram was collected during three consecutive health check-ups at 2-year intervals to calculate cumRHR.Six common cardiovascular risk factors were recorded,including smoking,alcohol consumption,hypertension,diabetes,hyperuricemia,and dyslipidemia.A three-year follow-up commenced after the third health check-up,with incident CVD(including coronary heart disease and ischemic stroke)as the endpoint event.The association between cumRHR and CVD risk was assessed using a Logistic regres-sion model,with subgroup analysis stratified by gender.Spearman correlation analysis was performed to examine the association of cumRHR with the number of accumulated cardiovascular risk factors.Results:During follow-up,21 participants occurred incident CVD.Compared to participants in the no CVD group,those in CVD group had sig-nificant higher proportions of smoking(47.6％vs.20.3％,P=0.003),hypertension(61.9％vs.35.9％,P=0.017),diabetes(38.1％vs.19.1％,P=0.035),hyperuricemia(38.1％vs.13.0％,P=0.002),dyslipidemia(71.4％vs.41.9％,P=0.008)and cumRHR[(349.90±30.24)bpm*year vs.(290.77±32.43)bpm*year,P＜0.001].After adjusting for confounding factors,multivariate Logistic regression analysis showed that cumRHR was still an independent risk factor of incident CVD(OR 1.05,95％CI 1.03～1.07,P＜0.001).This association remained in subgroup analysis stratified by gender in both males and females(OR 1.05,95％CI 1.03～1.07 and OR 1.06,95％CI 1.03～1.09,respectively,P＜0.001 both).Spearman correlation analysis detected a positive correla-tion between cumRHR and number of accumulated cardiovascular risk factors≥3(r=0.459,P＜0.001).Conclu-sion:Higher cumRHR is associated with an increased risk of CVD,and there is a significant positive correlation be-tween the number of accumulated cardiovascular risk factors and the risk of elevated cumRHR.
