Abstract:
Objectives:To investigate the association of trajectories of atherogenic index of plasma(AIP)with the risk of atherosclerotic cardiovascular disease(ASCVD). Methods:A total of 51 831 employees and retirees who participated in Kailuan Group health examination for three consecutive times from 2006 to 2010 were included in this study.AIP was calculated using the log(triglycerides[TG]/high-density lipoprotein-cholesterol[HDL-C])formula.AIP trajectory models were fitted by the SAS Proc Traj program,and according to AIP trajectory,the subjects were divided into low stability group(n=11 114),low to moderate stability group(n=21 647),medium to high stability group(n=13 659),and high stability group(n=5 411).Kaplan-Meier method was used to calculate the cumulative incidence of ASCVD in different groups and compared by log-rank test.Cox proportional risk regression model was used to analyze the effects of different AIP trajectories on ASCVD risk. Results:Finally,51 831 patients were included in the analysis.During a mean follow-up of(10.19±2.22)years,5 142(9.92%)subjects developed ASCVD,4 013(7.74%)subjects died.Cox regression analysis after adjusting for confounding factors showed:compared with the low stability group,the risk of ASCVD increased by 13%(HR=1.13,95%CI:1.04-1.23,P=0.003)and 20%(HR=1.20,95%CI:1.10-1.31,P＜0.001)and 41%(HR=1.41,95%CI:1.27-1.57,P＜0.001)in the low to moderate stability group,moderate to high stability group and high stability group,respectively,and the risk increased gradually(Ptrend＜0.001).Stratified analysis showed that the risk of ASCVD in people aged＜65 years and low-density lipoprotein cholesterol(LDL-C)＜3.4 mmol/L with long-term high levels of AIP was higher than that in people aged≥65 years and LDL-C≥3.4 mmol/L(both Pinteraction＜0.01). Conclusions:In Kailuan Study cohort,those with long-term high levels of AIP had a higher risk of ASCVD,and the risk gradually increased.In addition,we found that the risk of ASCVD in people with long-term high levels of AIP was higher in＜65 years old than in≥65 years old,and the risk of ASCVD in people with LDL-C＜3.4 mmol/L was higher than that in people with LDL-C≥3.4 mmol/L.
