Abstract:
Objectives:To investigate the correlation between resting heart rate(RHR)and atherosclerotic cardiovascular disease(ASCVD)and all-cause death in young and middle-aged people.Methods:A prospective cohort study was conducted enrolling 72 642 young and middle-aged participants(aged<60 years),who participated in the medical examination of the Kailuan Study from June 2006 to October 2007.According to the quartile of the RHR level,the participants were divided into Q1 group(<67 beats/min,n=14 381),Q2 group(67-70 beats/min,n=15 815),Q3 group(71-75 beats/min,n=15 876),Q4 group(76-80 beats/min,n=13 933)and Q5 group(>80 beats/min,n=12 637).Cox proportional hazard regression model was used to analyze the effect of RHR on ASCVD and all-cause death.The dose-response relationship between RHR and the risk of ASCVD and all-cause death was investigated using a restricted cubic spline regression model.Results:During a mean follow-up of(10.0±4.85)years,2 898 patients(3.99%)developed ASCVD.Multivariate Cox regression analysis showed that after adjusting for confounding factors,the risk of RHR and ASCVD in group Q5 increased by 20%compared with group Q1(HR=1.20,95%CI:1.06-1.35,P<0.05).There was no significant risk in groups Q2 to Q4 compared to Q1 group(all P>0.05).In addition,the risk of ASCVD increased by 4%for every 10 beats/min increase in RHR(HR=1.04,95%CI:1.01-1.07,P=0.009).During the follow-up period of(10.2±4.82)years,all-cause death occurred in 2 175 participants(2.99%).The results showed that compared with Q1 group,the risk of all-cause death in Q3 to Q5 groups increased by 33%(HR=1.33,95%CI:1.15-1.54,P<0.001),33%(HR=1.33,95%CI:1.14-1.54,P<0.001),and 78%(HR=1.78,95%CI:1.54-2.05,P<0.001)respectively,and there was no statistical significance between group Q2 and group Q1.The risk of all-cause death increased by 15%for every 10 beats/min increase in RHR(HR=1.15,95%CI:1.11-1.19,P<0.001).Restricted cubic spline analysis showed that RHR was linearly correlated with risk of ASCVD(Poverall=0.022,Pnon-linear=0.617),and the risk of ASCVD increased significantly with RHR>72 beats/min.RHR was linearly associated with the risk of all-cause death(Poverall<0.001,Pnon-linear=0.212),and the risk of all-cause death was significantly increased with RHR>72 betas/min.Conclusions:Higher RHR is associated with an increased risk of ASCVD and all-cause mortality in young and middle-aged individuals.
