Purpose: The purpose was to identify quality of chest pain according to causal diseases and pain expression of patients with coronary artery diseases. Method: Participants were 1,964 patients with pain who visited the emergency department of A hospital from January to December 2006. Data were collected from nurses' and doctors' records as to causal disease, and quality and expression of chest pain. Results: Causal diseases were coronary artery diseases, non-specific chest pain, respiratory diseases, non-coronary artery heart diseases and digestive diseases in that order of frequency. Every disease except respiratory disease caused mostly dull and tract pain, but 63.7% of patients with coronary artery diseases complained of typical angina pain and 24.9% complained of atypical angina pain. Patients with coronary artery diseases mostly used word 'heaviness' in describing their dull pain, and 'squeezing' for tract pain. Both male and female patients who were diagnosed with coronary artery disease complained mostly frequently of dull pain and tract pain. Conclusion: The most common causal disease for patients with chest pain was coronary artery disease. Patients with other diseases also frequently complained of dull and tract pain, the same as patients with coronary artery diseases. A considerable number of patients complained various types of atypical angina pain in coronary artery diseases.

The object of this study was to investigate the relationship between stress and the extent of coronary artery stenosis in 101 patients with coronary artery diseases. Global assessment of recent stress(GARS) scale and perceived stress response inventory were used to measure perception for stressors and stress responses. Biological variables such as the extent of coronary artery stenosis, the number of the affected lesions on coronary angiography, serum Low Density Lipoprotein(LDL)-cholesterol, High Density Lipoprotein(HDL)-cholesterol, and total cholesterol were measured in all the subjects. Scores of perceived stress related to changes in relationship and overall global scores on GARS scale had significantly positive correlation with the extent of coronary artery stenosis. On the other hand, scores of percieved stress related to changes in relationship and changes or no changes in routine had significantly positive correlation with the number of the lesions. Scores of perceived stress related to change or no change in routine also positively correlated with serum level of LDL-cholesterol and total cholesterol. In contrast, general somatic symptoms negatively correlated with the extent of coronary artery stenosis. Impulsive-aggressive behavior negatively correlated with the number of the lesions. However, impulsive-aggressive thinking positively correlated with LDL-cholesterol. The above results suggest that perception for stressors may negatively affect the extent of coronary artery stenosis, the number of the lesions, serum LDL-cholesterol and total cholesterol. However, some stress responses showed inconsistent effect on the above biological variables. Thus, strategies designed to modify perception for stressors and some stress responses are likely to help the patients minimize the extent of coronary artery stenosis and prevent the diseases.

Recently we experienced coronary artery bypass graft in two patients over 70years of age. Among them, one case was 74 old year male and the other case was 73 old year male. The coronary artery diseases of them were angiographically diagnosed to triple vessel diseases. We only used great saphenous vein as graft vessel in two patients. The postoperative courses were good except mediastinal bleeding in 1 case. They were discharged with good results. They were still healthy 40 months in one and 30 months in the other after coronary artery bypass grafting.

Coronary vasospasm is one of the fatal complications that may occur in patients undergoing open heart surgery. To date, however, there are not many cases in this series and no definite pathophysiology has been documented. We experienced a case of coronary artery vasospasm after atrial septal defect (ASD) surgery and then successfully treated it with both transbrachial intraaortic balloon pump and percutaneous cardiopulmonary support. Only several hours after ASD surgery, the patient exhibited the cardiovascular collapse, the ST-segment elevation, followed by ventricular fibrillation and normal coronary angiography findings. It is important to make a differential diagnosis of coronary artery vasospasm in patients presenting with ST-segment elevation who had no notable coronary artery diseases. This case indicates that clinicians should be aware of the possibility that the coronary artery vasospasm may also occur in patients undergoing ASD surgery.

Stenosed coronary artery may play an important role in various coronary heart diseases. However, it has not been known how much stenosed coronary artery affects coronary circulation system, quantitatively. The present study developed a mathematical model for microcirculation in the left common coronary artery (LCCA) with adopting a previously measured morphological data and mechanical properties of the coronary vessels. We examine the effect of percent diameter stenosis on blood flow rate and shear stress for two cases. Case I comprised of one-stenosed element at $10^{th}$ order ($\%$ diameter stenosis are 10, 30, and 50, respectively). Case II consisted of completely occluded element at $10^{th}$ order (number of occluded elements are 0, 1, and 2 out of 8, respectively). As the level of stenosis becomes severe, the shear stress increases significantly but the flow rate reduction was relatively small. However, for the occluded case, there was linearly proportional reduction of flow rate according to number of occluded elements. Either such high shear stress associated with coronary artery stenosis or reduced flow rate due to occlusion may cause atherosclerosis and myocardial ischemia.

본 연구의 목적은 관상동맥질환 환자들과 정상인 간의 분노수준을 비교하고자 하는 것이었다. 233명의 관상동맥질환 환자들과 215명의 정상대조군을 대상으로 조사하였다. 분노수준을 평가하기 위해서 분노표현척도, 스트레스반응척도의 분노 및 공격성 하위척도, SCL-90-R의 적대감 하위척도를 사용하였다. 관상동맥질환 환자군은 정상대조군보다 분노표현 하위척도점수 및 분노전체 하위척도 점수, 스트레스반응척도의 분노 및 공격성 하위척도 점수가 각각 유의하게 더 높았다. 협심증 환자들은 심근경색증 환자들보다 분노표현 하위척도점수 및 분노전체 하위척도 점수가 유의하게 더 높았다. 환자군에서 남자는 여자보다 분노억제 하위척도 점수가 유의하게 더 높은 반면, 여자는 남자보다 분노표현 하위척도 점수가 유의하게 더 높았다. 이상의 결과는 관상동맥 질환 환자들이 정상인들보다 분노수준, 특히 분노표현의 정도가 더 높다는 것과 성별에 따라 분노표현에 차이가 있음을 시사해 준다. 또한 환자들의 높은 분노 수준은 병의 경과에 나쁜 영향을 미칠 수 있다는 점에서 관상동맥질환 환자들에 대한 분노관리의 필요성이 강조된다.

Coronary artery diseases are very important agenda in the insurance medicine. Insurance medicine is defined as using medical knowledge for insurance administration such as underwriting, claims, and customer satisfaction. This review article contains review of coronary artery disease in terms of insurance medicine. Estimation of extra-risks for acute myocardial infarction are MR of 349% and EDR of 41‰. In medical underwriting, individual life applicants can be assessed by Framingham's CHD risk assessment model. In claims, medical claims review is a useful method of consulting for claims staffs. Several diagnostic criteria of acute myocardial infarction are introduced in time. The universal definition of myocardial infarction by ESC/ACCF/WHF was demonstrated the most valuable predictor of 10-year mortality. Contents for State-Of-The-Art of the coronary artery disease are current antithrombotics. There are many novel anti-thrombotic agents such as ticagrelol, dabigatran, rivaroxaban, and pegnivacogin.

관상동맥-폐동맥 누공은 비교적 드문 질환으로 선천적 원인이 대부분이나 최근 흉부 시술이나 방사선 치료의 증가로 점차 후천적 원인이 많아지는 추세이다. 증상이 비특이적이어서 진단이 늦어질 수 있어 주의를 요한다. 저자들이 경험한 환자는 기존의 폐질환 증상 때문에 심장 혈관 질환의 진행을 예측하기 어려웠다. 약간의 논쟁이 있으나 원인에 계 없이 크기가 작은 누공에서는 추적관찰이, 중등도 이상의 크기이거나 확장 가능성이 있는 경우에는 누공을 막거나 원인혈관을 제거하는 방법이 장되고 있다. 예후는 대체로 양호한 편이다.

분진에 노출 되었던 집단을 대상으로 폐질환 선별검사를 위해 시행한 저선량 CT영상의 관상동맥 석회화 소견과 석회화수치 CT검사 결과를 비교 분석하였다. 연구윤리심의위원회의 승인과 연구대상자로부터 동의서를 받은 후, 과거 분진에 노출된 직업력을 갖고 있는 61명의 남자를 대상으로 폐질환의 선별검사를 위해 저선량 CT촬영과 석회화수치 CT검사를 동시에 실시하였다. 저선량 CT영상(Axial image)은 영상의학과 전문의로부터 진폐 소견 및 폐질환과 관상동맥 석회화소견에 대해 판독하였고, 석회화수치 CT검사로부터 얻은 기초 영상(Row image)은 별도의 워크스테이션으로 보내져 상업적인 라피디아 소프트웨어(ver 2.8)를 이용하여 관상동맥 석회화수치를 구하였다. 저선량 CT영상에서 석회화소견을 보이지 않은 그룹(42명, 68.9%)과 보인 그룹(19명, 31.1%)사이에 총 석회화(13.68 vs. 582.93, p=.009), 좌전하행관상동맥 (3.15 vs. 248.95, p=.006)의 석회화수치가 통계학적으로 유의한 차이를 보였고, 좌주관상동맥, 좌회선관상동맥, 우관상동맥에서 석회화소견을 보인 그룹에서 높게 나타났다(p>0.05). 저선량 CT영상의 석회화소견은 석회화수치 CT검사의 석회화수치 100에서 가장 높은 일치도(K-value=0.80, 95% 신뢰구간=0.69-0.91)를 보였다. 폐질환을 조기 발견하기 위해 시행된 저선량 CT영상에서 보여진 석회화소견은 석회화수치 검사결과와 높은 관련성을 보임으로써 폐쇄성 관상동맥질환을 예측할 수 있는 것으로 사료된다.

저자들은 1992년 10월부터 1994년 8월사이에 전남대학교병원 흉부외과에서 좌주관동맥협착으로 외과적 치료를 받았던 21례의 임상소견을 분석, 보고하고저 한다. 남자가 12례, 여자가 9례였으며 연령은 75세부터 67세가지로 평균 49.12$\pm$12.54세였다. 불안정 협심증이 14례 (66.7%), 안정 협심증이 4례(19. 0%).급성 심근경색증이 3례였다 병변은 단순 좌주관동맥협착이 11례(52.4%)로 가장 많았는데 이중 5 례가 좌주관동맥개구부헙착 환자였으며 단일, 이중, 삼중 관동맥협착과 동반된 례가 4례(19.0%), 3례 (14.2%). 3례(14.2%)이었다. 수술수기로는 16례 에서 관동맥우회로이식술을, 개구부협착만 있었던 5례에서 자가 심낭을 이용한 개구부성 형술을 시행하였는데 관동맥우회로이식술을 시행하였던 전례에서 내유동맥을 사용하여 좌전하행지에 문합하였고, 1례에서는 대둔지에 연쇄문합을 실시하였다. 술후 1례(4. 76%)가 출혈 및 저심박출증으로 술후 2일째 사망하였으며 수술합병증으로는 출혈에 의한 재수술 2례, 창상감염 2례 및 부정맥 1례 등이 있었다. 좌주관동맥질환의 외과적 치료후 수술사망율이나 합병증 발 생율은 다른 부위의 관동맥질환의 외과적 치료에 비해 높지 않았으며 40대 이하의 여자에서 발생빈도가 높은 좌주관동맥 개구부형 착에서는 미용상의 문제, 혈역학적 특성 및 향후 재수술시 이식편 등을 고려할 때 자가 심낭을 이용한 개구부성 형술이 의의있는 수술수기로 생각된다.
