Purpose: This study was performed to analyse the trends of risk factor management programs for patients with coronary artery disease. Methods: Using PubMed, 35 intervention studies related to risk factor management programs among randomized controlled trials searched with the key words of coronary artery disease and coronary heart disease. Collected studies were analysed according to the characteristics of studies and participants, method and content of intervention, and outcome indicator and its effects. Results: The mean period of intervention was $28.7{\pm}26.8$ weeks, the mean frequency was $3.0{\pm}2.0$ times per week, and the duration of one session was below 60 minuets in 65.8% of the reviewed studies. The interventions were counselling, exercise, education, and cognitive behavior therapy. Counselling was applied most frequently in previous studies. The outcomes of intervention had been measured with anthropometric, physical, physiological, psychological, behavioral, and cognitive aspects, but the effect of the intervention was inconsistent among the studies. Conclusion: Based on the results of this study, systematic and comprehensive cardiac rehabilitation program consisted of counselling, exercise, and education should be developed and performed for health management and relapse prevention of patients with coronary artery disease.

Forty cases of coronary artery bypass grafting treated at the Department of Thoracic and Cardiovascular Surgery, SNUH, Korea were compared with forty cases of the procedure treated at University of Alberta Hospital, Canada, in terms of pathoanatomy. That showed no difference in sex ratio between Korean and Caucasian the average ages, however, were 50.4 years and 60.9 years respectively [p< 0.005]. The leading cause of angina at presentation was unstable angina in Korean, but it was post-infarction angina in Caucasian instead. The incidences of single-vessel disease and double-vessel disease were similar in both countries, but the incidence of so-called triple-vessel disease was higher in Caucasian while left main coronary artery disease was more prevalent in Korean [0.01< P, 0.005]. < The internal diameters of surgically available coronary artery branches had similar characteristics and no significant statistical differences were found between them. The predilection sites of stenoses were proximal left anterior descending artery, left main coronary artery, proximal left circumflex artery and proximal right coronary artery decreasing in incidence respectively, in Korean. The myocardial perfusion score were 6.80 in single-vessel disease, 7.56 in double-vessel disease, 11.27 in triple-vessel disease and 9.77 in left main disease respectively, in Korean.

Coronary artery involvement in Takayasu's arteritis is a relatively rare, and potentially lethal but surgically correctable disease. A 28-year-old female was admitted for the evaluation of headache associated with dizziness, palpitation and claudication of left arm. Her aortogram and coronary angiogram showed Takayasu's arteritis with bilateral coronary ostial stenosis. We performed bilateral coronary ostioplasty with saphenous vein patch graft. The patient was discharged in good condition. We report this case with literature review.

We have experienced a case of coronary artery bypass surgery without extracorporeal circulation through limited anterior thoracotomy. The lesion was a single vessel disease involving the take off of the left anterior descending artery(LAD) which showed tubular lesion with irregular contour and eccentric stenosis of more than 95% luminal narrowing. Percutaneous transluminal coronary angioplasty(PTCA) seemed to have moderate success rate and moderate complication rate. A segment of left internal mammary artery(LIMA) from the second rib down to the sixth rib was harvested through the bed of resected fourth costal cartilage. Anastomosis between LIMA and LAD was performed under beating condition. The patient was extubated in the operation room and showed excellent postoperative course without complications. The coronary angiography on the postoperative 7th day revealed good patency at the anastomosis site.

The Kawasaki disease has been reported worldwide since the first description in 1967 in Japan. Approximately 20% of the children with untreated Kawasaki disease are believed to develop coronary artery aneurysm of which 2-3% progress to coronary artery stenosis. The Kawasaki disease rarely affects adults and accordingly, there have been only a few cases reported in literatures. The present case describes a successful surgical treatment of a 43-year-old female patient with coronary artery aneurysm and stenosis, which resulted from an episode of the Kawasaki disease that occurred 20 years earlier. The patient was well at 5 months followup.

Coronary artery spasm immediately after the coronary artery bypass graft (CABG) surgery is rare but it can cause sudden and severe hypotension or a ventricular arrhythmia. We report a case of low cardiac output syndrome caused by a right coronary artery spasm following CABG that did not show any significant stenotic lesions on preoperative coronary angiography.

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is an extremely rare, potentially fatal, congenital anomaly with a high mortality rate in the first year of life. It occurs rarely in adulthood and may appear with malignant ventricular arrhythmia or sudden death. We report a case of a 49-year-old woman with ALCAPA who presented with dyspnea on exertion. Management was coronary artery bypass grafting to the left anterior descending artery and obtuse marginal arteries, closure of the left main coronary artery ostium, and reestablishment of the dual coronary artery system.

Purpose: This study was done to examine the effects of heat therapy on low back pain, blood pressure and pulse rate after percutaneous coronary intervention. Method: The participants in this study were 40 patients who were admitted after having percutaneous coronary intervention. The experimental group, 20 patients, had heat therapy and the control group, 20 patients, maintained a supine position for 12 hours after the intervention. Back pain (VAS), blood pressure and pulse rate were measured just after removal of the sheath, and at 2-hour intervals up to 6 hours. Data were analyzed using SPSS 15.0. Results: The experimental group had significantly lower VAS for low back pain (F=23.44, p=.001). However no significant differences were found between two groups for blood pressure and pulse rate. Conclusion: The findings indicate that heat therapy is effective in reducing low back pain in patients who have had percutaneous coronary intervention. Therefore, heat therapy could be used as nursing intervention percutaneous coronary intervention.

In this study, a novel hierarchical approach is investigated to extract coronary vessel from X-ray angiogram. First, we propose to combine Decimation-free Directional Filter Bank (DDFB) and Homographic Filtering (HF) in order to enhance X-ray coronary angiographic image for segmentation purposes. Because the blood vessel ensures that blood flows in only one direction on vessel branch, the DDFB filter is suitable to be used to enhance the vessels at different orientations and radius. In the combination with HF filter, our method can simultaneously normalize the brightness across the image and increases contrast. Next, a coarse-to-fine strategy for iterative segmentation based on Otsu algorithm is applied to extract the main coronary vessels in different sizes. Furthermore, we also propose a new approach to segment very small vessels. Specifically, based on information of the main extracted vessels, we introduce a new method to extract junctions on the vascular tree and level of nodes on the tree. Then, the window based segmentation is applied to locate and extract the small vessels. Experimental results on our coronary X-ray angiography dataset demonstrate that the proposed approach can outperform standard method and attain the accuracy of 71.34%.

Purpose: The purpose of this study was to elucidate the relationship between readiness to quit smoking and smoking cessation, and identify factors associated with smoking cessation in smokers with ischemic heart disease post-coronary angiography (CAG). Methods: This descriptive study was conducted between December 1, 2020 and May 14, 2021 at a P hospital, Busan. A total of 164 subjects completed the questionnaire including general characteristics, coronary artery disease characteristics, readiness to quit smoking, and smoking cession behavior during hospitalization and 4 weeks after discharge. Results: The success rate of smoking cessation after coronary angiography in patients with ischemic heart disease was 49.4% (n = 81). In addition, 48.2% of smokers (n = 83) attempted smoking cessation after CAG, while 39.8% showed changes in smoking behavior. The readiness to quit smoking was significantly associated with smoking cessation (OR= 2.23, p< .005). Conclusion: Readiness to quit smoking was identified as an important factor associated with smoking cessation in patients with cardiovascular disease in this study. In order to increase the smoking cessation rate, it is necessary to strengthen the readiness to quit smoking, followed by a tailored program for smoking cessation in patients with ischemic heart disease.
