Genetic factors are important in the pathogenesis of coronary artery disease (CAD). Angiotensin converting enzyme (ACE) gene insertion(I)/deletion(D) polymorphism is one of the genetic factor found to be related with CAD. We investigated the association between I/D polymorphism of the ACE gene and the presence of CAD. Threehundred and seven patients (187 males and 120 females, aged between 35-80, mean $54.3{\pm}9.8$ years) who underwent diagnostic coronary angiography were included in the study. ACE I/D polymorphism was detected by polymerase chain reaction. Of the 307, 176 had CAD. The most frequently observed genotype in all subjects was ID (47.9 %). However, in patients with CAD the frequency of II genotype was lower whereas DD genotype was higher compared to the controls (p < 0.05). The number of D allele carrying subjects were also higher (p < 0.05) in CAD patients. The logistic regression analysis indicated that the ACE D allele is an independent risk factor (odds ratio = 1.48, 95% CI = 1.01-2.18, p < 0.05). In conclusion, the I/D polymorphism of ACE gene (carrying D allele) is an independent risk factor for CAD in the studied Turkish population.

Gastritis is a major disease that has the potential to grow as gastric cancer. Gastric cancer is a very common cancer, and it is related to a very high mortality rate in Korea. This disease is known to have various reasons, including infection with Helicobacter pylori, dietary habits, tobacco, and alcohol. The incidence rate of gastritis has reported to differ between age, population, and gender. However, unlike other factors, there has been no analysis based on gender. So, we examined the high risk factors of gastritis in each gender in the Korean population by focusing on sex. We performed an analysis of 120 clinical characteristics and genome-wide association studies (GWAS) using 349,184 single-nucleotide polymorphisms from the results of Anseong and Ansan cohort study in the Korea Association Resource (KARE) project. As the result, we could not prove a strong relation with these factors and gastritis or gastric ulcer in the GWAS. However, we confirmed several already-known risk factors and also found some differences of clinical characteristics in each gender using logistic regression. As a result of the logistic regression, a relation with hyperlipidemia, coronary artery disease, myocardial infarction, hyperlipidemia therapy, hypotensive or antihypotensive drug, diastolic blood pressure, and gastritis was seen in males; the results of this study suggest that vascular disease has a potential association with gastritis in males.

Purpose: The purpose of this study was to develop a motivational enhancement therapy (MET) for coronary artery disease (CAD) patients in early stages of health behavior change and evaluate its effects on health motivation, the stages of change, health behaviors, and cardiovascular risk factors. Methods: Using a non-equivalent control pre-post design, the study was conducted on 42 CAD patients who underwent medical treatment or percutaneous coronary interventions in a hospital. The intervention group (n=21) received the MET (MET 1 during admission, MET 2 after discharge via telephone). The control group (n=21) received a standard care. Data were analyzed using descriptive statistics, ${\chi}^2-test$ and t-test with the SPSS 12.0 program. Results: Participants in the intervention group reported significantly increased scores of health motivation (t=-2.093, p=.043), the stages of change (t=-5.682, p<.001), and health behaviors (t=-3.069, p=.004) and significantly decreased scores of cardiovascular risk factors (t=2.131, p=.039) compared to those of the control group. Conclusion: The findings indicate that the MET is an effective intervention in improving health behaviors and decreasing cardiovascular risk factors for CAD patients.

The purpose of this study was to evaluate the performance of deep neural network model in order to determine whether there is a risk factor for coronary artery disease based on the cardiac variation parameter. The study used unidentifiable 297 data to evaluate the performance of the model. Input data consists of heart rate parameters, which are SDNN (standard deviation of the N-N intervals), PSI (physical stress index), TP (total power), VLF (very low frequency), LF (low frequency), HF (high frequency), RMSSD (root mean square of successive difference) APEN (approximate entropy) and SRD (successive R-R interval difference), the age group and sex. Output data are divided into normal and patient groups, and the patient group consists of those diagnosed with diabetes, high blood pressure, and hyperlipidemia among the various risk factors that can cause coronary artery disease. Based on this, a binary classification model was applied using Deep Neural Network of deep learning techniques to classify normal and patient groups efficiently. To evaluate the effectiveness of the model used in this study, Kernel SVM (support vector machine), one of the classification models in machine learning, was compared and evaluated using same data. The results showed that the accuracy of the proposed deep neural network was train set 91.79% and test set 85.56% and the specificity was 87.04% and the sensitivity was 83.33% from the point of diagnosis. These results suggest that deep learning is more efficient when classifying these medical data because the train set accuracy in the deep neural network was 7.73% higher than the comparative model Kernel SVM.

Objectives: The objective of this study was held for prevention of coronary artery disease and improvement of health of local community residents by classifying the obesity types of their waist circumference and BMI, and appraising the coronary artery disease risk factors(CRF). Methods: We analyzed the data on the 1,914 adult cases (1,156 male and 758 female) during Nov, 2006 to Mar. 2007 on a general hospital in Daegu city, Korea. The obesity types in this research were classified into normal group, seeming obesity group, abdominal obesity group and obesity group. Also, CRF was classified by normal, mild, moderate, and severe, and each class was given the index from 0 to 3. The coronary artery disease risk factors index(CRFI) was defined as the sum of index, and we defined that if the sum is higher, higher chance of coronary artery disease risk exist. Results: According to the research, by the age group, normal group has higher percentage in age 30 to 40, and obesity group and abdominal obesity group has higher percentage in age 50 to 60. CRFI is increased by order of normal group, seeming obesity group, abdominal obesity group, and obesity group on both male and female groups, and male shows higher index than female on all four groups. CRFI will be influenced by order of obesity group, seeming obesity group, and abdominal obesity group on male, and obesity group, abdominal obesity group, and seeming obesity group on female according to the result of multiple regression between obesity type and CRFI. Conclusion: According to the result from our research, we have to have keen attention to not only seeming obesity group and obesity group, but also abdominal obesity group which has normal waist circumference influence to CRFI. So, those kinds of indexes have to be controled by controling their weight. Also, we believe that health behaviour can improve and CRF can be prevented by the early health care and early health education to those with no abnormal indication on clinical indicator but with abnormal BMI and waist circumference.

A total of 40 patients having a diagnosis of atherosclerotic coronary arterial disease were analysed on the operative outcomes according to variables as follows: 1) preoperative risk factors such as age, sex, CCS (Canadian Cardiovascular Society) functional class, type of angina, number of diseased vessel, presence of left main coronary artery stenosis, previous history of habitual smoking and presence of other medical diseases (diabetes mellitus, essential hypertension), 2) preoperative management such as intravenous infusion of nitroglycerine, preoperative IABP (intra-aortic balloon pump) support and whether the operation was scheduled as emergency or not, 3) intraoperative variables such as infusion method and composition of cardioplegic solutions, number of distal anastomosis, use of internal mammary artery, total cardiopulmonary bypass time and total cross clamp time. Complications included operative death in 12.5％, perioperative myocardial infarction in 25.0％ and perioperative arrhythmia in 17.5％. Nineteen perioperative variables were analyzed to identify risk factors for these end points. For operative death, presence of left main coronary artery stenosis (p = 0.056) and cardiopulmonary bypass time (p = 0.029) were significant in the univariate analysis, but presence of left main coronary artery lesion (p = 0.011, $\chi$$^2$= 6.45) and abscence of preoperative of IABP support (p = 0.069, $\chi$$^2$ = 3.30) were independent predictor in multivariate analysis (stepwise linear logistic regression).

1994년 1월부터 1996년 7월까지 관상동맥 우회로 이식술을 받았던 87명을 대상으로 수술후 심근경색의 진단에 있어서 심전도 검사의 가치를 평가해 보았고 심전도에 의해 진단된 심근경색의 위험인자에 대해 조사하였다. CK-MB 최고치의 평균과 LDH1/LDH2의 비가 1이상인 경우의 빈도는 new Q파군, ST변화군 및 심전도상 변화가 없는군 간에 유의한 차이가 있었다. 심전도상 new Q파 또는 48시간이상 지속되는 ST절 변화가 있을 때 심근경색으로 진단하였다. 병원 사망률은 3.3%이며, 술후 심근경색 발생률은 17.2%였다. 술후 심근경색의 중요한 위험인자들은 1) 관상동맥 내막절제술, 2) 좌심실 박출계수의 저하(ejection fraction 40%이하), 3) 대동맥 차단시간의 연장이었고, 좌주관상동맥 질환, 3혈관 질환, 이식혈관이 3개이상인 경우, 불안정형협심증 및 고혈압 등은 술후 심근경색 발생과 연관성이 없었다. 이상에서 관상동맥 우회로 이식술후에 발생하는 심근경색의 진단에 심전도 검사는 유용한 방법이 될 수 있다고 생각된다.

The three hundred and sixty nine patients who underwent either isolated or concomitant coronary artery bypass graft surgery since May, 1977 till December, 1993 at the Yonsei University Cardiovascular center were studied with respects to the incidence of operative risk factors, surgical methodology and consequent results. The patients were classified into two periods, according to the time of the surgery in relation to the date of the opening of the Yonsei cardiovascular center. Period I[1977 to 1990 , consisting of the patients who underwent surgery prior to the opening date, harboured a total of 189 patients with the mean age of 55 years, and the second, Period II[1991 to 1993 , those who underwent after the opening, of 180 patients with the mean age of 60 years. The Period II patients were involved in more operative risk factors, compared to the ones in Period I. The anatomy of the coronary arteries of the patients of Period II were more likely to have multilesional and left main disease. The patients in Period I were older, had more prominent left ventricular dysfunction and were more likely to be exposed to the risk factors. The number of implanted grafts were greater period II[average of 2.5 grafts per patient in Period I VS 3.2 in Period II and the frequency which the used left internal mammary artery was also significantly higher in Period II[49 and 104 cases in Period I and Period II . The incidence of perioperative myocardial infarction was 20 patients[10.6% in Period I, 14 patients[7.8% in period II. And the operative mortality was 20 patients[10.6% in period I, 8 patients[4.4% in period II. In conclusion we think that the operative results have improved in Period II, compared to that of Period I, in spite of the higher risks, due to accumulation of surgical experiences, improved surgical techniques and myocardial protection, specialized teamwork, application of the intraoperative TEE and appropriate pharmacological interventions by anesthesiologist.
