Aim: Weight change could have many health outcomes. This study aimed to investigate the association between weight change and mortality risk due to total cardiovascular disease (CVD), ischemic heart disease (IHD), and stroke among Japanese. Methods: We used Suita Study data from 4,746 people aged 30-79 years in this prospective cohort study. Weight change was defined as the difference between baseline weight and weight at age 20. We used Cox proportional hazards models to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) of total CVD, IHD, and stroke mortality for 1) participants with a weight change (>10, 5 to 10, -5 to -10, and <-10 kg) compared to those with stable weight (-4.9 to 4.9 kg) and 2) participants who moved from one body mass index category (underweight, normal weight, or overweight) to another compared to those with normal weight at age 20 and baseline. Results: Within a median follow-up period of 19.9 years, the numbers of total CVD, IHD, and stroke mortality were 268, 132, and 79, respectively. Weight loss of >10 kg was associated with the increased risk of total CVD mortality 2.07 (1.29, 3.32) and stroke mortality 3.02 (1.40, 6.52). Moving from normal weight at age 20 to underweight at baseline was associated with the increased risk of total CVD, IHD, and stroke mortality: 1.76 (1.12, 2.77), 2.10 (1.13, 3.92), and 2.25 (1.05, 4.83), respectively. Conclusion: Weight loss, especially when moving from normal to underweight, was associated with the increased risk of CVD mortality.

Aims: This study aimed to investigate the association of mild hypertensive retinopathy with cardiovascular disease (CVD) risk. Methods: A total of 7,027 residents aged 30–79 years without a history of CVD participated in the annual health checkups and retinal photography assessments. Retinal microvascular abnormalities were graded using the standard protocols and classified according to the Keith–Wagener–Barker classification. Mild hypertensive retinopathy was defined as grades 1 and 2. Cox proportional hazard model was used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for total CVD and its subtypes according to the presence and absence of mild hypertensive retinopathy. Results: During a median follow-up of 17 years, 351 incident stroke and 247 coronary heart disease (CHD) cases were diagnosed. After adjustment for traditional cardiovascular risk factors, mild hypertensive retinopathy was positively associated with risk of CVD (multivariable HR=1.24; 95% CI, 1.04–1.49) and stroke (1.28; 1.01–1.62) but not with risk of CHD (1.19; 0.89–1.58). Generalized arteriolar narrowing and enhanced arteriolar wall reflex were positively associated with CVD risk, the multivariable HR (95% CI) was 1.24 (1.00– 1.54)and 1.33 (1.02–1.74), respectively. Moreover, mild hypertensive retinopathy was positively associated with stroke risk in normotensive participants. Conclusion: Mild hypertensive retinopathy was positively associated with CVD and stroke risk in the urban Japanese population. Especially, generalized arteriolar narrowing and enhanced arteriolar wall reflex were positively associated with CVD risk. These findings suggested that retinal photography could be helpful for cardiovascular risk stratification in the primary cardiovascular prevention.

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.
