Abstract

Aim: A prospective cohort study in a Japanese urban general population was performed to investigate whether triglyceride (TG) and its related indices were associated with the risk for the incidence of ischemic cardiovascular disease (CVD) after the adjustment for low-density lipoprotein cholesterol (LDL-C) in Asian community dwellers. Methods: A 15.1-year prospective cohort study was performed in 6,684 Japanese community dwellers aged 30–79 years without a history of CVD and whose fasting TG levels were <400 mg/dL. After adjusting for covariates, including LDL-C, the multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) of the deciles (D) of TG and those of 1-standard deviation (SD) increment of log-transformed TG (1-SD of TG) according to LDL-C level (≥ 140 and <140 mg/dL) for ischemic CVD incidence were estimated. The multivariable-adjusted HRs and 95%CIs of the quintiles (Q) of TG, TG/HDL-C, and the cardiometabolic index (CMI) for ischemic CVD were also estimated. Results: In 101,230 person-years, 464 ischemic CVD cases occurred. For D10 of TG, the HR (95%CI) was 1.56 (1.05–2.32), and for 1-SD of TG, it was 1.30 (1.00–1.70) in participants with LDL-C <140 mg/dL and 1.07 (0.77–1.50) in those with LDL-C ≥ 140 mg/dL. For Q5 of the CMI, the multivariable-adjusted HR was higher than those of TG and TG/HDL-C. Conclusions: Fasting TG was an independent predictor for ischemic CVD incidence after adjusting for LDL-C in Japanese community dwellers with TG <400 mg/dL. Among TG, TG/HDL-C, and the CMI, the CMI could be the most powerful predictor for ischemic CVD.
