This study aimed to demonstrate the impact of cumulative burden of cardiovascular risk factors (CVRFs) on risk of cardiovascular events (CVEs). A total of 34959 participants were enrolled who participated in the four surveys during 2006-2013. Cumulative CVRF burden was calculated as number of years (2006-2013) multiplied by the values of CVRFs including systolic blood pressure, fasting blood glucose (FBG), low-density lipoprotein cholesterol (LDL-C), and high-sensitive C-reactive protein (hs-CRP). The primary outcome was defined as the CVE during 2012-2017, including ischaemic stroke, myocardial infarction, and all-cause mortality. During 4.62 (±0.71) years follow-up on average, there were 2118 (6.06%) CVE, including 847 (2.42%) ischaemic stroke, 221 (0.63%) myocardial infarction, and 1185 (3.39%) all-cause mortality. Higher cumulative burden of individual CVRF was significantly associated with increased risk of outcomes, except for LDL-C for all-cause mortality, FBG for myocardial infarction, and hs-CRP for ischaemic stroke. In Cox proportional hazards model, compared with the group, of the lower quartile of integrated cumulative burden, the hazard ratio (95% confidence intervals) of the upper quartile was 2.45 (2.03-2.94) for CVE, 3.65 (2.68-4.96) for ischaemic stroke, 4.51 (2.19-9.27) for myocardial infarction, and 1.73 (1.36-2.21) for all-cause mortality. We demonstrated the correlation between cumulative burden of CVRFs and cardiovascular risk, except for cumulative burden of hs-CRP and ischaemic stroke. Thus, our study suggests the necessity to extend the observation duration of CVRFs in order to elucidate the life-course cumulative effect.
