This cross-sectional study was conducted to describe the changes of plasma cardiovascular disease(CVD) risk factors in Korea. Overnight fasting plasma levels of total cholesterol, high density lipoprotein(HDL)-cholesterol, triacylglycerol and glucose were analyzed. Blood pressure and anthropometric data were also measured. Health practice factors such as smoking status, alcohol consumption and frequency fo exercise were evaluated by a self-administered questionnaire. Questions regarding dietary habits and food preferences were also asked. Seventy eight percent of the subjects had more than one CVD risk factor. Plasma total cholesterol, triacylglycerol, and fasting blood glucose were significantly increased according to the subjects body mass index$(kg/m^2$, BMI), whereas HDL-cholesterol, low density lipoprotein(LDL)-cholesterol and blood pressure showed no significant differences with BMI. Current smokers had significantly high plasma total cholesterol, LDL-cholesterol and triacylglycerol levels. Alcohol consumption significantly increased plasma total cholesterol and fasting blood sugar, but regular exercise had no effects on the plasma CVD risk factors. Overeating and frequency of fast food consumption were positively correlated with the CVD risk score, whereas intake of grains, meats and vegetables were negatively correlated with that score. A stepwise multiple regression analysis was performed to examine the effects of specific dietary factors on plasma lipid levels. For plasma total cholesterol level, the frequency of fast food intake explained 8% of the variance, followed by habitual overeating, frequency of grain intake and high cholesterol food intake(Model $R^2$=22.4%). For plasma triacylglycerol level, preference of oily foods accounted for 7.5% of the variance, followed by eating breakfast, preference of fruit and frequency of grain intake(Model $R^2$=22.0%). The findings suggest that intervention programs to reduce the risk of CVD should focus on health practice through reducing BMI, smoking cessation and moderate or no alcohol drinking. Moreover, desirable dietary habits such as eating breakfast, not overeating and reduced intake of fast food may improve CVD risk.

Purpose: This study was conducted to identify the clinical characteristics and risk factors on the occurrence of variant angina, and to examine the predicting factors on the vascular endothelial dysfunction of the patients with variant angina. Methods: A total of 134 patients diagnosed with variant angina were recruited from 2006 to 2008. The degrees of endothelial dysfunction were measured and recorded by the researcher using the values of flow-mediated vasodilation of their brachial arteries and Nitroglycerine-mediated dilation. Subjects' demographic data and risk factors were gathered after obtaining informed consent, and their electronic medical records were reviewed to collect laboratory data. Results: The mean age was $54.2{\pm}9.6$ years and 52% was male patients. More than 50% of the male patients were cigarette smokers and had hypercholesterolemia. 84% of the male patients and 70% of the female patients had more than one risk factor of cardiovascular disease. A stepwise multiple regression analysis showed that smoking and hypercholesterolemia predicted the decrease of flow-mediated vasodilation (Adjusted $R^2$ = .204, p < .001). Conclusion: Tailored educational interventions for smoking cessation and cholesterol management are needed to prevent recurrence of angina attack for patients with variant angina and to prevent cardiovascular disease for middle-aged workers.

Purpose: This study was to investigate the lifestyle characteristics and risk of cardiovascular disease (CVD) among workers with metabolic syndrome(MS). Methods: The descriptive cross-sectional survey design was used. A total of 187 workers with MS were recruited from a university hospital. The anthropometric measures were used and blood data were reviewed from the health record. Data were analyzed using descriptive statistics and multiple logistic regressions with SPSS/WIN 12.0. Results: While 52.2% of women did not do exercise regularly, 30.5% of men did not at all. The prevalence of MS according to each component was as follows: hypertension was 92.0%, obesity was 89.8%, hyperlipidemia was 63.1%, and hyperglycemia was 61.0%. The high prevalence of each component of MS in workers with MS indicated a significantly higher risk of CVD. The odds ratio of risk of CVD was 16.04 (p=.017) in workers with hypertension, when compared to workers without hypertension. Similarly, the odds ratio of risk of CVD was 11.04 (p=.000) in workers with hyperglycemia, compared to workers without hyperglycemia. Conclusion: Increased risk of CVD was significantly associated with lifestyle characteristics and MS risk factors among Korean workers with MS.

Objective: The purpose of this study is to identify the incidence risk of cardiovascular disease (CVD) in the workplace, and to suggest the prediction models for level of CVD incidence risk. Background: CVD can be caused by various factors related to personal habits such as diet and exercise, or genetics. However it can also be caused and aggravated by work, making the elimination of such risk factors at work crucial disease (KOSHA, 2013). Method: The distribution of CVD risk assessment levels of 162 workers was compared with the acquired medical examination data to discuss the necessity of assigning additional risk factors. Two alternative risk assessment models were given to enhance the accuracy of the evaluation; adjusting risk scores given in the KOSHA GUIDE H-1-2013 (alternative 1) and building a matrix of KOSHA GUIDE H-1-2013 and risk assessment results based on work condition levels (alternative 2). To verify the suggested models, medical examination results of 12 workers approved of convalescence were referred to. Results: The second alternative showed more relevance between the results and workers approved of convalescence in predicting the risk group when applied to actual heath examination data from the approved workers. The power of description of the new method for determining the risk of CVD incidence, 83.3%, is higher than that of KOSHA GUIDE H-1-2013, 25%. Conclusion: Results of this study imply that more approved workers had been from unmanaged normal groups than managed risk groups, raising the importance of CVD management. Application: The new prediction model considering working time and shift work developed in this study is expected to be a fundamental data for risk analysis and management of CVD in the workplace.

Cardiovascular diseases are the leading cause of death and disability in Korea. Their risk factors can be classified as either modifiable or nonmodifiable and among modifiable factors are high bood pressure, elevated blood cholesterol, obesity and cigarette smoking. The purpose of this study was to evaluate the risk factors for the cardiovascular diseases in a rural community and to get basic data for the development of a community-based rick reduction intervention program. Evaluation involved population-based, cross-sectional samples of adult residents in a rurual community. We measured blood pressure, body fat percent by bioelectric impedance fatness analyzer and serum cholesterol and interviewed adult residents over 20-year-old age. Blood pressure was checked twice and hypertension was classified by the sixth report of the Joint National Committee on Detection. Evaluation, and Treatment of High Blood Pressure. The Cutpoints for high blood cholesterol was used National Cholesterol Treatment Guidelines and those for obesity was 25% in male. 30% in female. The results were as follows: 1. Prevalence of definitive hypertension was 59.7% in males and 54.4% in female. 2. Prevalence of hypercholesterolemia was 14.3% in male and 18.2% in female. 3. Prevalence of obese was 10.7% in male and 41.1% in female. 4. Among definitive hypertension, hypercholesterolemia, and obesity 52.1% possessed one risk factor, 12.6% two risk factors and 2.5% three risk factors in males. In females 41.4% possessed one risk factor and 27.6%. 5.7% respectively. 5. The smoking rate was 65.8% in males and 5.2% in females. Our results are used effectively for the community-based intervention towards cardiovascukr diseases risk reduction. However, because of limitations in our study design, further datas are needed including other risk factors and in-person clinical datas.

Background/Aims: Epicardial adipose tissue (EAT) shares pathophysiological properties with other visceral fats and potentially triggers local inflammation. However, the association of EAT with cardiovascular disease (CVD) is still debatable. The study aimed to observe the changes and associations in EAT and risk factors over time, as well as to investigate whether EAT was associated with CVD. Methods: A total of 762 participants from Seoul National University Hospital (SNUH) and SNUH Gangnam Center were included in this study. EAT was measured using coronary computed tomography angiography. Results: Baseline EAT level was positively associated with body mass index (BMI), calcium score, atherosclerotic cardiovascular disease (ASCVD) 10-year risk score, glucose, triglycerides (TG)/high-density lipoprotein (HDL), but not with total cholesterol, low-density lipoprotein (LDL). At follow-up, EAT levels increased in all groups, with low EAT groups demonstrating a significant increase in EAT per year. Change in EAT was associated with a change in BMI, TG/HDL, and glucose, while changes in LDL, calcium score, and ASCVD 10-year risk score were not associated. Although calcium score and ASCVD 10-year risk score were associated with CVD events, baseline information of EAT, baseline EAT/body surface area, or EAT change was not available. Conclusions: Metabolic risks, e.g., BMI, TG/HDL, and glucose, were associated with EAT change per year, whereas classical CVD risks, e.g., LDL, calcium score, and ASCVD 10-year risk score, were not. The actual CVD event was not associated with EAT volume, warranting future studies combining qualitative assessments with quantitative ones.

Purpose: The purpose of this study was to identify the link between health-related physical fitness level and cardiovascular disease-related risk factors in adult male workers. Methods: We tested cardiovascular disease-related risk factors (waist circumference, SBP, DPB, fasting glucose, TC, HDL-C, TG, LDL-C) and health-related physical fitness ($VO_2max$, grip, Sit-up, Flexibility, Body fat) and divided health-related physical fitness level of the subjects into 3 groups - A (very good, n=56), B (good, n=59), and C (below-average, n=57) according to the criterion of the Health and Fitness counseling guidelines of KOSHA. The statistical techniques such as standard deviation, one-way ANOVA and multiple regression (p<.05) were used. Results: There were significant differences between group C and group B & A (p<.001) in waist circumference, DBP, Fasting glucose, HDL-C, TG, LDL-C. In TC/HDL-C, TG/HDL-C, LDL-C/HDL-C, Group C was higher than group B and A. Conclusion: On the basis of these results, we identified that improvement of health-related physical fitness level positively effects on the decrease of cardiovascular disease-related risk factors.

Purpose: The purpose of this study was to evaluate the prevalence, awareness, treatment and control of hypertension, diabetes, and dyslipidemia among women with rheumatoid arthritis. Methods: This cross-sectional study of 288 women with rheumatoid arthritis was conducted in a university-affiliated hospital. Data were collected by reviewing the women's medical charts and self-report questionnaires. Results: The prevalence of hypertension, diabetes and dyslipidemia was 27.8%, 5.9% and 48.3%, respectively. Despite the high prevalence of dyslipidemia, the subjects'awareness of it and its treatment rates were the lowest, which resulted in a low control rate. Of the 288 subjects, 158 (55%) had at least one of the three conditions. The prevalence of the combination of cardiovascular risk factors increased with age, and 32.7% of those aged 60 or older had two or three of the cardiovascular risk factors. Combinations of cardiovascular risk factors were significantly related with severe pain and fatigue. Conclusion: Cardiovascular risk factors were highly prevalent among the women with rheumatoid arthritis, but the rates of awareness, treatment, and control were suboptimal. There is a pressing need to facilitate the prevention, early detection and appropriate management of hypertension, diabetes and dyslipidemia among patients with rheumatoid arthritis in order to prevent cardiovascular disease.

Background: Dynapenic obesity and sarcopenic obesity increase cardiovascular disease (CVD) and mortality in nonuremic patients. The present study was designed to determine the prevalence of dynapenic obesity and sarcopenic obesity and their associations with CVD risk factors in peritoneal dialysis (PD) patients. Methods: All eligible PD patients in Tehran peritoneal dialysis centers were included in this cross-sectional study. Skeletal muscle mass and fat mass were assessed using bioelectrical impedance analysis. Muscle strength and physical performance were determined using hand grip strength and a 4-meter walk gait speed test, respectively. In addition, a 5-mL blood sample was obtained from each patient. Results: The prevalence of dynapenic obesity and sarcopenic obesity were 11.4% and 3.8% in PD patients, respectively. Serum high-sensitive C-reactive protein (hs-CRP), soluble intercellular adhesion molecule type 1, triglyceride, total cholesterol, and low-density lipoprotein cholesterol were significantly higher in PD patients with dynapenic obesity than in dynapenic nonobese and nondynapenic nonobese patients. Similarly, serum concentrations of CVD risk factors in PD patients with sarcopenic obesity were higher than in nonsarcopenic nonobese patients, but these differences were statistically significant only for serum hs-CRP and triglyceride. In addition, muscle strength and skeletal muscle mass percentage were negatively associated with markers of inflammation and dyslipidemia, whereas body fat percentage was positively associated with these CVD risk factors. Conclusion: This study indicates that although the prevalence of dynapenic obesity and sarcopenic obesity are relatively low in PD patients, these disorders may be associated with CVD risk factors.
