Abstract BackgroundDyslipidemia is an independent health risk of cardiovascular disease (CVD), a leading cause of mortality in older adults. Despite their importance, there have been few reports on the association between lipoprotein cholesterol and future CVD and cardiovascular (CV) mortality among elderly Asians. This longitudinal study investigated the correlations in an elderly Korean population by using a large nationwide sample.MethodsAmong participants in the cohort database of the Korean National Health Insurance Service who completed the National Screening Program, a total of 62,604 adults aged 65 years or older (32,584 men and 30,020 women) were included. High-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) values were categorized by quartiles. Cox proportional hazard models were used to assess the association between the quartiles of lipoprotein cholesterol and CV events or CV mortality.ResultsThe mean follow-up period was 3.3 years. The incidence rates of ischemic heart disease and ischemic brain disease were 0.97 and 0.61 per 1,000 person-years, while the mortality rates from these diseases were 0.22 and 0.34 per 1,000 person-years, respectively. In a fully adjusted model, high HDL-C and LDL-C levels were not associated with the total CV events and CV mortality; however, high LDL-C levels were significantly associated with a lower incidence of ischemic brain disease. Furthermore, diabetic patients with high LDL-C were more likely to have higher CV mortality, whereas non-smokers with high LDL-C were less likely to be at risk of CV events. ConclusionsNeither high LDL-C nor HDL-C was significantly associated with future CV mortality in older adults aged ≥65 years. Older adults with diabetes were significantly associated with a higher risk of CV mortality in high LDL-C levels.

Abstract Background Dyslipidemia is considered an independent health risk factor of cardiovascular disease (CVD), a leading cause of mortality in older adults. Despite its importance, there have been few reports on the association between lipoprotein cholesterol and future CVD and cardiovascular (CV) mortality among elderly Asians aged ≥ 65 years. This study investigated the association between lipoprotein cholesterol and future CVD and CV mortality in an elderly Korean population using a large nationwide sample. Methods From the cohort database of the Korean National Health Insurance Service, 62,604 adults aged ≥ 65 years (32,584 men and 30,020 women) were included. High-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) levels were categorized by quartiles. Cox proportional hazard models and linear regression analyses were used to assess the association between the quartiles of lipoprotein cholesterol and future CV events or mortality. Results The mean follow-up period was 3.3 years. The incidence rates of ischemic heart disease and ischemic brain disease were 0.97 and 0.61 per 1,000 person-years, respectively, and the mortality rates from these diseases were 0.22 and 0.34 per 1,000 person-years, respectively. In a completely adjusted model, high HDL-C and LDL-C levels were not associated with total CV events and CVD mortality. However, high LDL-C levels were significantly associated with a lower incidence of ischemic brain disease. Furthermore, diabetic patients with high LDL-C levels were more likely to have higher CV mortality, whereas non-smokers with high LDL-C levels were less likely to be at risk of CV events. Conclusions Neither high LDL-C nor HDL-C levels were significantly associated with future CV mortality in older adults aged ≥ 65 years. High LDL-C levels do not seem to be a risk factor for CVD in elderly individuals, and further studies are required.

Abstract Background: Serum lipid profile is an important factor in predicting the risk of cardiovascular disease, and smoking is considered to affect serum lipid levels adversely by altering lipid metabolism. Although traditional lipid profiles are important in patient evaluation for predicting the risk of cardiovascular disease, the clinical significance of lipid ratios has recently gained attention as well. We aimed to investigate the relationship between smoking and serum lipid profiles and ratios in Korean older adults.METHODS: This cross‐sectional analysis used a nationally representative sample from the 2014–2016 Korea National Health and Nutrition Examination Survey (KNHANES). In total, 4,349 participants aged ≥60 years with urine cotinine values were included. The outcome was a comparison of unfavorable lipid profiles/ratios in respect to urine cotinine-verified smoking status (urine cotinine level ≥50 ng/mL), and quantification of the associations between smoking and unfavorable lipid profiles/ratios using multivariable logistic regression analyses. In our analyses, the lowest quartile (Q1) of high-density lipoprotein cholesterol (HDL-C), and the highest quartile (Q4) of low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), and total cholesterol (TC), and their ratios (TC/HDL-C, LDL-C/HDL-C, and TG/HDL-C) were considered as unfavorable.Results: The percentages of unfavorable lipid profiles/ratios except for serum TC and LDL-C were significantly higher in the urine cotinine-verified smoker group. The odds ratios (ORs) and 95% confidence intervals (CIs) of urine cotinine-verified smokers for the Q1 of HDL-C and for the Q4 of TG, TC/HDL-C, LDL-C/HDL-C, and TG/HDL-C were 1.67 (95% CI: 1.29–2.17) and 1.49 (95% CI: 1.14–1.96), 1.50 (95% CI: 1.14–1.97), 1.44 (95% CI: 1.10–1.89), and 1.75 (95% CI: 1.35–2.28), respectively.Conclusion: Urine cotinine-verified smoking status was significantly associated with unfavorable serum lipid profiles/ratios in Korean older adults.
