Constant technological developments in coronary artery disease have contributed to the assessment of both the presence of coronary stenosis and its hemodynamic consequences. Hence, noninvasive imaging helps guide therapeutic decisions by providing complementary information on coronary morphology and on myocardial perfusion and metabolism. This can he done using single photon emission computed tomography (SPECT) or positron emission tomography (PET) and multidetector CT (MDCT). Advances in image-processing software and the advent of SPECT/CT and PET/CT have paved the way for the combination of image datasets from different modalities, giving rise to hybrid imaging. Three dimensional cardiac hybrid imaging helped to confirm hemodynamic significance in many lesions, add new lesions such as left main coronay artery disease, exclude equivocal defects, correct the corresponding arteries to their allocated defects and identify culprit segment. Cardiac hybrid imaging avoids the mental integration of functional and morphologic images and facilitates a comprehensive interpretation of coronaty lesions and their pathophysiologic adequacy by three dimensional display of fused images, and allows the best evaluation of myocardial territories and the coronary-artery branches that serve each territory. This integration of functional and morphological information were feasible to intuitively convincing and might facilitate development of a comprehensive non-invasive assessment of coronary artery disease.

Coronary artery disease has historically been a contraindication to lung transplantation. We report a successful combined bilateral lung transplantation and off-pump coronary artery bypass in a 62-year-old man. The patient had a progressive decline in lung function due to idiopathic pulmonary fibrosis and a history of severe occlusive coronary artery disease.

The occlusive coronary artery disease presents a potential threat to a significant population in the United State. According to many case reports, the increasing incidence of coronary artery disease due to atherosclerosis is noted in Korean, recently. We experienced one case of coronary artery disease. He was a 68 year old male who had been suffered from hypertension since 1 5 years ago, and had intermittent conservative treatment at local clinic. He had been afflicted with severe chest pain on exertion, but this symptom was relieved on rest. Pre-operative EKG finding revealed no any other ischemic sign. Significant S-T segment depression was noted at lead II, aVF, V3, V4, and V5, and inverted T wave in V5 and V6 after Master`s test. Simple chest X-ray finding showed emphysematous field, bilaterally. Final pre-operative diagnosis was made by coronary angiogram, which showed almost 90% degree of occlusive lesion in the proximal part of left main coronary artery above the origin LAD artery. He was treated successfully by aorta-coronary saphenous vein graft under extra-corporeal circulation in May, 1987. He has been followed up with uneventful course.

Occlusive coronary artery disease presents a potential threat to a significant population in the United States. According to many case reports, the increasing incidence of coronary artery disease due to atherosclerosis is noted in Korean, recently. Operative vascular procedures have increased steadily in number over the past 20 years in the United States. There have been many isolated case reports about coronary artery surgery, but these had little clinical impact. Nowadays, major three coronary bypass surgery has developed principally at three cardiac centers in the United States since 1967. Among three coronary bypass operation, the aorta-coronary artery saphenous vein bypass graft was first demonstrated by Favolaro and Effler at the Cleveland Clinic in 1967. We experienced one case of coronary artery disease, which was treated successfully by aorta-coronary saphenous vein graft with mild hypothermia under extracorporeal circulation in May, 1977. Saphenous vein was removed from above the knee and was 2.5 mm in diameter. The left ventricle was not vented for the left ventricle was not overdistended. Temporary artificial pace-maker-Medtronic-was implanted for the prevention and treatment of post-operative arrhythmia and heart block in post-operative first day. He is a 57 year old male businessman who had been suffered from hypertension [200 mmHg in systolic pressure] since 4 years ago, who had intermittent conservative treatment at local clinic. He had been afflicted with severe chest pain with choking sensation for 50 days. This symptom was aggravated exposing cold weather, or cold water, but was respond to rest. Pre-operative ECG revealed no any other ischemic sign except sinus bradycardia. Significant S-T segment depression was noted at lead II, AVF after double 5 minutes exercise, indicating positive Master`s test. Serum cholesterol was slight elevated to 253 mg/dl. Final pre-operative diagnosis was made by coronary arteriogram, which showed about 1.0-cm segmental 90 % occlusive atherosclerotic lesion in the proximal part of right coronary artery above the origin of acute marginal artery. Left coronary artery revealed good patency and there was no collateral circulation between right and left coronary artery .Hospital course was not eventful. He was discharged with good result on the post-operative day. He has been free from chest pain for longer than 2 years. And also the arterial flow in the coronary bypass graft is auscultated with the pocket-sized ultrasonic velocity detector, which shows the patency of the coronary bypass graft good.

Purpose: The purpose of this study was to investigate the knowledge and learning needs on coronary artery disease in diabetic patients by glycemic control. Methods: The subjects consisted of 188 patients at the hospital who had diabetes mellitus. Data was obtained using a knowledge and learning needs questionnaire from January to April 2006. Results: Treatment method, the levels of fasting blood glucose(FBG), and 2-hour postprandial blood glucose(PP2hr) showed meaningful differences between normo-glycemic group(HbA1c < 7%) and hyper-glycemic group($HbA1c{\geq}7%$). The levels of knowledge on coronary artery disease by glycemic control tend to show higher in normo-glycemic group. Etiology and prevention of coronary artery disease were significantly higher in normo-glycemic group than in hyper-glycemic group. The levels of learning needs on coronary artery disease by glycemic control tend to show higher in normo-glycemic group. The learning needs on items of diet control were higher in normo-glycemic group than in hyper-glycemic group. Conclusion: On the base of these results, we should focus on the coronary artery disease education for hyper-glycemic group. Also individual coronary artery disease educational program should be developed for the patients with different level of knowledge and learning needs.

Purpose: The purpose of this study was to assess the difference in knowledge and learning needs of the coronary artery disease according to the general characteristics of the patients with type 2 diabetes mellitus. Method: The participants were 188 patients who had diabetes mellitus. Data were obtained between January and April 2006 by asking the knowledge and learning needs of the coronary artery disease. Data were analyzed using SAS program. Results: Participants' knowledge level was high in the cause and prevention, but the level was low in the symptom and occurrence of pain. Learning need for "Influence of smoking on heart disease" and "The structure and functions of the heart" was great, but learning need for "Complete diagnosis" and "Management of pain and pressure on the sternum" was little. No significant differences were found in the knowledge level of the coronary artery disease according to the general characteristics. Learning needs were greater in participants under 60 years of age (p=0.011) and in those with low education level (p=0.049). There was a significant correlation between knowledge and learning needs of the coronary artery disease (p=0.003). Conclusion: In planing the education programs, the general characteristics of the patients should be considered.

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.

Purpose: This study was aimed to identify the factors that influence eating behaviors in coronary artery disease patients and to create data for nursing which is thought to improve the eating behavior. Method: The study population was coronary artery disease patients who were treated on an outpatient basis. The measurements were eating behavior, diet self-efficacy, perceived-benefits, perceived-seriousness, family support and medical team support. All of the measurement tools above were thoroughly modified to verify validity and reliability. Statistical analysis was done by the SPSS PC 12.0 program. Results: The influencing factors for the eating behavior was diet self-efficacy (${\beta}=0.476$), social support (${\beta}=0.253$), chest pain (${\beta}=0.177$), smoking (${\beta}=-0.173$) and regular exercise (${\beta}=.169$), which explained 46.2%. Conclusion: Eating behaviors of coronary artery disease patients were influenced by diet self-efficacy, family support and the presence of chest pain. Therefore, the development of a program for efficient dietary education that prevents the progression of coronary artery disease is needed.

Throughout its 30-year history, the right gastroepiploic artery (GEA) has been useful for in situ grafts in coronary artery bypass grafting (CABG). The early graft patency rate is high, and the late patency rate has improved by using the skeletonized GEA graft and proper target selection, which involves having a target coronary artery with a tight >90% stenosis. Total arterial revascularization with the internal thoracic artery and GEA grafts is an option for achieving better outcomes from CABG procedures.

Moyamoya disease is an unusual cerebrovascular disorder characterized by occlusive intimal dysplasia of the distal internal carotid and proximal cerebral arteries as well as other collateral arteries. However, moyamoya diseases are recently being reported as a systemic process. We experienced one case of coronary artery occlusive disease affected by moyamoya disease. The patient was a 35-year-old female, experiencing intermittent NYHA class ll dyspnea and exertional chest pain for 6 months and right paresthesia for 1 month before admission. Cerebral artery angiogram showed abnormal cerebrovascular systems and confirmed moyamoya disease with cerebral infarction of the left frontal lobe. In coronary artery angiogram, left coronary artery was not visualized due to total occlusion of the left main ostium and left coronary blood flow was supplied from normal right coronary artery. CABG was performed with OPCAB. Both internal mammary arteries were used for LAD and LCx. Intraoperative coronary artery findings showed intimal hyperplasia and no definite thrombi, and nondiseased coronary arteries were good and patent. We concluded that this patient's coronary artery disease was affected by moyamoya disease, and moyamoya disease should be evaluated in the extracerebral cardiovascular system.
