Moderate alcohol consumption has been known to be associated with reduced risk for coronary heart disease (CHD). We assessed the association between alcohol consumption and CHD-related risk factors [hypertension, diabetes mellitus (DM) , high total cholesterol, high triglyceride (TG), low HDL-cholesterol (HDL-C), and high LDL-cholesterol (LDL-C)] in Korean. After excluding those with extreme intake values, the number of final subjects included in the analysis was 4,662 Korean adults aged over 20 years (1,961 men, 2,701 women) who participate in the 2005 Korean National Health and Nutrition Examination Survey. The subjects were divided into four or five groups; none-alcohol consumption group, moderate alcohol consumption group (<15 or 15.0-29.9 g/d), heavy alcohol consumption group (30-69.9 g/d or ${\geq}$ 70 g/d in men, ${\geq}$ 30 g/d in women). Odds ratios (ORs) were estimated from logistic regression adjusting for potential covariates. Alcohol consumption was inversely associated with low HDL-C in both men and women. However, heavy alcohol intake (${\geq}$ 70 g/d) significantly increased risk for hypertension, DM, and hypertriglyceridemia in men. The frequency of alcohol intake was also associated with CHD risk. The risk for low HDLC was decreased with alcohol consumption (${\geq}$ 1 times/wk), but frequent alcohol intake (${\geq}$ 4 times/wk) increased the risk for hypertension. This study revealed that moderate alcohol consumption has protective effect on CHD-related risk factors in Korean population.

Background and Objectives: The History, Electrocardiography, Age, Risk factors, and Troponin (HEART) pathway was developed to identify patients at low risk of a major adverse cardiac event (MACE) among patients presenting with chest pain to the emergency department. Methods: We modified the HEART pathway by replacing the Korean cut-off of 25 kg/m² with the conventional threshold of 30 kg/m² in the definition of obesity among risk factors. The primary outcome was a MACE within 30 days, which included acute myocardial infarction, primary coronary intervention, coronary artery bypass grafting, and all-cause death. Results: Of the 1,304 patients prospectively enrolled, MACE occurred in 320 (24.5%). The modified HEART pathway identified 37.3% of patients as low-risk compared with 38.3% using the HEART pathway. Of the 500 patients classified as low-risk with HEART pathway, 8 (1.6%) experienced MACE, and of the 486 low-risk patients with modified HEART pathway, 4 (0.8%) experienced MACE. The modified HEART pathway had a sensitivity of 98.8%, a negative predictive value (NPV) of 99.2%, a specificity of 49.0%, and a positive predictive value (PPV) of 38.6%, compared with the original HEART pathway, with a sensitivity of 97.5%, a NPV of 98.4%, a specificity of 50.0%, and a PPV of 38.8%. Conclusions: When applied to Korean population, modified HEART pathway could identify patients safe for early discharge more accurately by using body mass index cut-off levels suggested for Koreans.

Respiratory syncytial virus (RSV) is a main cause of hospitalization for bronchiolitis and pneumonia in infants worldwide. Children with hemodynamically significant congenital heart disease (HS-CHD), as well as premature infants are at high risk for severe RSV diseases. Mortality rates for CHD patients hospitalized with RSV have been reported as about 24 times higher compared with those without RSV infection. Recently with advances in intensive care, mortality rates in CHD patients combined with RSV have decreased below 2%. The requirements of intensive care and mechanical ventilation for CHD patients with RSV infection were still higher than those without RSV infection or with non-CHD children. RSV infection has frequently threatened CHD infants with congestive heart failure, cyanosis, or with pulmonary hypertension. As a progressive RSV pneumonitis in those infants develops, the impairment of oxygen uptake, the breathing workload gradually increases and eventually causes to significant pulmonary hypertension, even after the operation. Preventing RSV infection as much as possible is very important, especially in infants with HS-CHD. A humanized monoclonal antibody, palivizumab, has effective in preventing severe RSV disease in high-risk infants, and progressive advances in supportive care including pulmonary vasodilator have dramatically decreased the mortality (<1%). Depending on the global trend, Korean Health Insurance guidelines have approved the use of palivizumab in children <1 year of age with HS-CHD since 2009. Korean data are collected for RSV prophylaxis in infants with CHD.

Background: The aim of this study was to evaluate the short-term and long-term results of surgical treatment for native valve endocarditis (NVE) and to investigate the risk factors associated with mortality. Methods: Data including patients' characteristics, operative findings, postoperative results, and survival indices were retrospectively obtained from Hallym University Sacred Heart Hospital. Results: A total of 29 patients underwent surgery for NVE (affecting the mitral valve in 20 patients and the aortic valve in 9) between 2003 and 2017. During the follow-up period (median, 46.9 months; interquartile range, 19.1-107.0 months), the 5-year survival rate was 77.2%. In logistic regression analysis, body mass index (p=0.031; odds ratio [OR], 0.574; 95% confidence interval [CI], 0.346-0.951), end-stage renal disease (ESRD) (p=0.026; OR, 24.0; 95% CI, 1.459-394.8), and urgent surgery (p=0.010; OR, 34.5; 95% CI, 2.353-505.7) were significantly associated with in-hospital mortality. Based on Cox proportional hazard regression analysis, the statistically significant predictors of long-term outcomes were hypertension, ESRD, and urgent surgery. Conclusion: Surgical treatment for NVE is associated with considerable mortality. The in-hospital mortality and 5-year survival rates of this study were 13.8% and 77.2%, respectively. Underlying conditions, including hypertension and ESRD, and urgent surgery were independent risk factors for unfavorable outcomes.

BACKGROUND/OBJECTIVES: The association between tea consumption and risk of coronary heart disease (CHD) remains controversial. This study aimed to determine whether tea consumption has an effect on CHD risk in Chinese adults. SUBJECTS/METHODS: In this hospital-based case-control study, 267 cases of CHD and 235 non-CHD controls were enrolled. Blood samples from all cases were examined. Cardiac function indices (left ventricular ejection fraction, left ventricular end-diastolic dimension, lactate dehydrogenase, and creatine kinase of the muscle or brain type), blood lipid index (high-density lipoprotein cholesterol), and blood coagulation function indices (fibrinogen and activated partial thromboplastin time) were recorded. Tea consumption of study participants was assessed by a specifically designed questionnaire. The baseline characteristics of the study populations were recorded, and CHD-related biomarkers were detected. Differences in baseline characteristics of the study participants were examined using t-tests for continuous variables and chi-squared tests for categorical variables. Unconditional logistic regression was used to measure the association between tea and CHD. RESULTS: There were significant differences in cardiac function indices, blood lipid index, and blood coagulation indices between CHD cases and controls (P < 0.05). We found tea consumption reduced CHD risk in female participants (adjusted odds ratio (OR) = 0.484, 95% CI: 0.242-0.968, P = 0.0403). Regarding the type of tea consumed, the risk of CHD was reduced in women who drank partially fermented tea (adjusted OR = 0.210, 95% CI: 0.084-0.522, P = 0.0008). Analytic results for the amount of tea consumed per unit time showed CHD risk was reduced in women who consumed 1-2 cups of tea per day (adjusted OR = 0.291, 95% CI: 0.131-0.643, P = 0.0023). A tea-drinking frequency of > 6 days/week was beneficial for CHD prevention (adjusted OR = 0.183, 95% CI: 0.049-0.679, P = 0.0112). When analyzed according to the duration of tea consumption, the risk of CHD was reduced in participants who had been drinking tea for 10-20 years (adjusted OR = 0.360, 95% CI: 0.137-0.946, P = 0.0382). CONCLUSIONS: Tea consumption is associated with a reduced risk of CHD in female but not male populations in Guangzhou.

The presence of left atrial thrombus in mitral stenosis has been reported to be associated with several factors. These are age, sex, presence of atrial fibrillation, episodes of congestave heart failure, calcification of mitral valve, embolic episode, etc. Since none of these single factor has been always related to the presence of left atrial thrombus, related risk factors to left atrial thrombosis were studied in patients with mitral stenosis using chi square test. We had operated on 191 cases of mitral valvular heart disease from Jan. 1978 to June 1981 at Severance Hospital, Yunsei University College of Medicine. The left atrial thrombi were present in 41 cases among 191 cases of mitral valvular heart disease and it was present in 31 cases among 89 cases of pure mitral stenosis. Only 10 cases among 74 cases of mitral stenoregurgitation had left atrlal thrombi, whereas no left atrlal thrombus was found in patients with pure mitral regurgitation. Related risk factors studied herein were sex, episodes of congestive heart failure, atrial fibrillation, pulmonary capillary wedge pressure, mitral valve area calculated by Gorlin and Gorlin`s formula cardiac output and left atrial dimension by echocardiogram. In this study presence of atrial fibrillation was deemed to be one of the most potential risk factors and other factors of age, duration of symptoms, episode of embolization, calclfication of mitral valve, associated aortic and tricuspid valve disease, ejection fraction of left ventricle by cineangiocardiogram and echocardiogram were not significantly related to the presence of left atrlal thrombi in a statistical viewpoint.

The purpose of this study was to investigate the distribution and correlation of stroke risk factor according to age with stroke patients. This study was based on clinical data registered in Daejeon Oriental Medical Hospital from November 2006 to December 2010. Study subjects consisted of 779 patients with stroke within 1 month and they were classified according to age and existence of past history such as hypertension, diabetes mellitus, ischemic heart diseaseand stroke family history. Stroke family history was distributed differently according to age unlike past history and in their 50's showed a particularly high rate. There was not statistically significant correlation between stroke family history and past history except for only between stroke family history and diabetes mellitus in the patients in their 80's and more. There was statistically significant correlation between hypertension and diabetes mellitus and especially in the patients in their 60's and 70's. There was statistically significant correlation between hypertension and ischemic heart disease and especially in the patients in their 80's and more. There was statistically significant correlation between diabetes mellitus and ischemic heart disease in the patients in their 60's. There was statistically significant correlation among hypertension, diabetes mellitus and ischemic heart disease, but stroke family history and past history had independence, so management and research for this subject should be required further and further.

Since the 1960s, Korea has achieved rapid economic growth, longer life expectancy, accelerated urbanization and a westenization of diet. Cardiovascular disease has become the leading cause of death; however the prevalence of ischemic heart disease(IHD) remains low. A cross-sectional multiphasic screening service for 18,426 persons aged $30\sim64$ years in a Medical Aid Program in Kyonggi-do Province was conducted from 1991 to 1993. Total cholesterol(TC), fasting blood glucose(FBG), blood pressure(BP), and electrocardiographic(EKG) data were collected. The result as follows ; 1. On the EKG findings, the age-adjusted prevalence of myocardial ischemia and myocardial infarction was 1.45% in men and 2.06% in women. 2. The mean blood pressure was 122.9/78.8mmHg. The age-adjusted prevalence of hypertension was 11.05% in men and 9.02% in women. The prevalence of hypertension showed increasing tendency according to age increase. In all age group, the prevalence of hypertension was higher in men than women. 3. The mean total cholesterol level was 184.4mg/dl in men and 189.2mg/dl in women. The age-adjusted prevalence of hypercholesterolemia was 4.88% in men and 5.67% in women. The total cholesterol level showed increasing tendency according to age increase, except $55\sim64$ age group in men. 4. The prevalence of hyperglycemia is 5.8%. The age-adjusted prevalence of hyperglycemia is 6.72% in men and 4.50% in women. The prevalence of hyperglycemia showed increasing tendency according to age increase. 5. On the EKG findings, the prevalence of myocardial ischemia and myocardial infarction was higher in hypertension than normal, in all age group of men and women less than 40 years-old. Only in women more t]fan 40 years-old, the prevalence of myocardial ischemia and myocardial infarction was higher in hypercholesterolemia and hyperglycemia. Nevertheless there is not statistical association between ischemia heart disease and previous risk factors in other age group, the prevalence of myocardial ischemia and myocardial infarction was higher in hypertension, hypercholesterolemia and hyperglycemia than normal. The result of this study suggest that relationships between major risk factor of ischemic heart disease and ischemic heart disease is similar to existing theory.

The purpose of this study is to identify the factors that may affect the 5-year survival of colon cancer through network model and to use it as a clinical decision supporting system for colorectal cancer patients. This study was conducted using data from 2,540 patients who underwent colorectal cancer surgery from 1996 to 2018. Eleven factors related to survival of colorectal cancer were selected by consulting medical experts and previous studies. Analysis was proceeded from the data sorted out into 1,839 patients excluding missing values and outliers. Logistic regression analysis showed that age, BMI, and heart disease were statistically significant in order to identify factors affecting 5-year survival of colorectal cancer. Additionally, a correlation analysis was carried out age, BMI, heart disease, diabetes, and other diseases were correlated with 5-year survival of colorectal cancer. Sex was related with BMI, lung disease, and liver disease. Age was associated with heart disease, heart disease, hypertension, diabetes, and other diseases, and BMI with hypertension, diabetes, and other diseases. Heart disease was associated with hypertension, diabetes, hypertension, diabetes, and other diseases. In addition, diabetes and kidney disease were associated. In the correlation analysis, the network model was constructed with the Network Correlation Coefficient less than p <0.001 as the weight. The network model showed that factors directly affecting survival were age, BMI levels, heart disease, and indirectly influencing factors were diabetes, high blood pressure, liver disease and other diseases. If the network model is used as an assistant indicator for the treatment of colorectal cancer, it could contribute to increasing the survival rate of patients.
