Mutations in the factor Ⅴ gene are major risk markers for venous thrombosis. Several factors for blood coagulation have been related with cardiovascular disease. Ⅰ investigated genotype distribution for three mutations (G1691 A, A2379G and G2391 A) of the factor Ⅴ gene in the Korean population. Genotype frequencies were examined by polymerase chain reaction in 135 patients with coronary artery disease (CAD) and 116 healthy subjects. For the G1691A mutation (factor Ⅴ

To study the relation between serum fatty acids and coronary artery disease(CAD), 194 subjects were randomly selected and divided into three groups(control, single vessel disease group(SVD), muliple vessel disease group(MVD)) according to the angiographic results. Total serum levels of fatty acids and serum phospholipid(PL)-fatty acids(FAs)were analysed using gas chromatography and their associations with CAD were examined. Different patterns of total serum fatty acid levels were found in men and women. Levels of most fatty acids of SVD and MVD were significantly lower in men, while those of MVD were significantly higher in women. In terms of PL-FAs in both men and women, the levels of PL-FAs follow the order of control < SVD < MVD and in women, the difference was significant. Various ratio(including ratios denoting the activites of desaturase and elongase) of total serum-and PL-FAs were similar in the three groups. In the relation of serum fatty acids to serum lipid profiles, PUFA & LDL showed a negative correlation, while, SFA & LDL-cholesterol and PUFA and HDL-cholesterol showed positive correlatons. correlations. Systolic blood pressure and alcohol intake levels negatively affected the levels of serum LA, AA, EPA and DHA in the risk factor analysis. These findings are consistent with other evidence indicating that fatty acid compositions are changed in CAD, especially on the concentration base and the change was related to the severity of the disease. Therefore, for the purpose of disease prevention and therapeutic use, balanced intakes of various fatty acids must be seriously considered.

Coronary artery disease (CAD) is one of the leading causes of death and disability all around the world. Recent studies have revealed that aberrantly regulated long non-coding RNA (lncRNA) as one of the main classes of cellular transcript plays a key regulatory role in transcriptional and epigenetic pathways. Recent reports have demonstrated that circulating lncRNAs in the blood can be potential biomarkers for CAD. HOTAIR is one of the most cited lncRNAs with a critical role in the initiation and progression of the gene expression regulation. Recent research on the role of the HOTAIR in cardiovascular disease lays the basis for the development of new studies considering this lncRNA as a potential biomarker and therapeutic target in CAD. In this study, we aimed to compare the expression of HOTAIR lncRNA in the blood samples of patients with CAD and control samples. The expression level was examined by semi-quantitative reverse transcriptase polymerase chain reaction technique. Our data shows that expression of HOTAIR is up-regulated in blood samples of patients with CAD.

Purpose: The purpose of this secondary data analysis was to identify factors influencing a relapse among patients with coronary artery disease (CAD). Methods: Of 250 participants enrolled in the original study 75 were selected as there was no relapse for more than one year following the initial treatment and 54 were selected because there was a relapse. Data were analyzed using ${\chi}^2$ test, t-test or F test to determine if there were any significant differences in the study variables relative to the status of relapse. Predictors were calculated by logistic regression. Results: Autonomy supported by healthcare providers was the significant predictor for relapse in patients with CAD. Patients with low autonomy supported by healthcare providers was 3.91 times more likely to relapse than patients with high autonomy supported. Patients with diabetes were at greater risk of recurrence. Conclusion: Secondary prevention of CAD is a major task for patients with CAD. Behavioral strategies for cardiovascular risk reduction are essential and autonomy supported by healthcare providers should be included in their strategies.

관상동맥질환의 임상적인 개념은 지난 10년 동안 패러다임의 변화를 보여왔다. 관상동맥질환은 대부분 진행성 질환이며, 관상동맥질환 환자는 질병 진행의 어느 시점에서도 급성 관상동맥 증후군에 직면할 수 있다. 이러한 임상적 맥락에서 2019년 유럽심장학회 가이드라인에서는 조기 진단과 꾸준한 관리가 필요한 관상동맥질환의 임상적인 중요성을 반영하여 "만성관상동맥증후군"이라는 용어의 사용을 발표하였다. 최근 관상동맥 전산화단층촬영 혈관조영술을 이용한 관상동맥질환의 평가는 많은 발전을 이루었고, 안정형 협심증 또는 만성 관상동맥증후군 환자에서 관상동맥 전산화단층촬영 혈관조영술의 임상적 유용성은 초기 무증상 관상동맥질환의 발견에서부터 죽상경화판의 특성 분석 및 관상동맥질환의 치료 전략 결정에 도움을 주는 역할까지 관상동맥질환의 다양한 단계에 걸쳐 입증되고 있다. 이 종설에서는 안정형 협심증 환자의 이해를 돕는 병태생리를 설명하고 이에 대한 관상동맥 전산화단층촬영의 임상적 적용과 역할에 대해 알아보고자 한다.

Objective: To compare the diagnostic performance of cardiovascular magnetic resonance (CMR) myocardial perfusion at 1.5- and 3-tesla (T) for detecting significant coronary artery disease (CAD), with invasive coronary angiography (ICA) as the reference method. Materials and Methods: We prospectively enrolled 281 patients (age $62.4{\pm}8.3$ years, 193 men) with suspected or known CAD who had undergone 1.5T or 3T CMR and ICA. Two independent radiologists interpreted perfusion defects. With ICA as the reference standard, the diagnostic performance of 1.5T and 3T CMR for identifying significant CAD (${\geq}50%$ diameter reduction of the left main and ${\geq}70%$ diameter reduction of other epicardial arteries) was determined. Results: No differences were observed in baseline characteristics or prevalence of CAD and old myocardial infarction (MI) using 1.5T (n = 135) or 3T (n = 146) systems. Sensitivity, specificity, positive and negative predictive values, and area under the receiver operating characteristic curve (AUC) for detecting significant CAD were similar between the 1.5T (84%, 64%, 74%, 76%, and 0.75 per patient and 68%, 83%, 66%, 84%, and 0.76 per vessel) and 3T (80%, 71%, 71%, 80%, and 0.76 per patient and 75%, 86%, 64%, 91%, and 0.81 per vessel) systems. In patients with multi-vessel CAD without old MI, the sensitivity, specificity, and AUC with 3T were greater than those with 1.5T on a per-vessel basis (71% vs. 36%, 92% vs. 69%, and 0.82 vs. 0.53, respectively). Conclusion: 3T CMR has similar diagnostic performance to 1.5T CMR in detecting significant CAD, except for higher diagnostic performance in patients with multi-vessel CAD without old MI.

Purpose: This study aimed to provide basic data for vascular health of patient who underwent percutaneous coronary intervention (PCI) by verifying the mediating effect of compliance in the relationship between risk level of coronary artery disease (CAD) and blood vessel elasticity. Methods: This is a descriptive study with 115 patients, who underwent the PCI a year ago and visited in the cardiology department from January to March, 2015. The risk level of CAD, blood vessel elasticity and the compliance were measured. For data analysis, SPSS/WIN 21.0 and AMOS (IBM) 21.0 were used. Results: There were a positive correlation with blood vessel elasticity score (i.e. inelasticity of the blood vessel wall) (r=.189) and a negative correlation with compliance (r=-.658) in mediating effect of risk level of CAD. There was a negative correlation between compliance and blood vessel elasticity (r=-.482). The direct effect (${\beta}=-.226$), indirect effect (${\beta}=.415$) and total effect (${\beta}=.186$) of mediating effect of risk level of CAD on blood vessel elasticity were significant. Compliance had a partial mediating effect of risk level of CAD on blood vessel elasticity. Conclusion: The results of this study suggest that managing and preventing moderating effect of risk level of CAD on compliance is helpful in restoring blood vessel elasticity.

Purpose: The purpose of this study was to identify the impact that health motivation, stage of change and cardiac risk factors have on health behaviors in Korean patients with coronary artery disease(CAD) admitted to hospital. Method: The participants in this study were 127 patients with CAD hospitalized between May 2008 and July 2009. A structured questionnaire with personal interviews and chart reviews were used to collect data. Data were analyzed using the SPSS. Results: Of the relatively significant factors, including a stage of change, self efficacy, modifiable risk factor score, and perceived barriers, stage of change was found to be the most significant predictor of health behavior in patients with CAD. These variables accounted for 48.2% of the variance in health behavior. Conclusion: The results of the study indicate the necessity of developing a cardiac rehabilitation program for use in their daily lives after discharge from the hospital. Stage of change should be assessed for all patients with CAD being discharged from acute care hospitals.
