본 연구는 협심증 발생의 위험요인에 관여하는 관련요인을 파악하기 위해 환자-대조군 연구를 시도 하였다. 자료수집은 2010년 12월 7일부터 2011년 2월 5일까지 서울에 소재한 종합병원에 내원한 협심증환자 141명을 대상으로 설문 및 면접조사를 하였다. 연구결과 첫째, 성별을 보면 환자군에서 여성 32.6%에 비해 남성 61.1%에서 유의하게 높았다($X^2$=11.94, p<.01). 둘째, 성별은 여성에 비해 남성에서 협심증의 위험요인이 3.24배 유의하게 높게 나타났다(OR=3.24, 95% Cl=1.93-6.84). 셋째, 남성, 현재흡연을 할수록, 당뇨병과 복부비만이 있는 경우 협심증 위험요인이 유의하게 나타났다(p<.05). 이러한 결과를 토대로 협심증에 이환된 대상자에게 철저한 장-단기적인 전략과 대책을 계획하고 수행하기 위한 방향을 제공하는 데 도움이 될 수 있을 것이다.

Background: There are many evidences that inflammation is an important determinant of the development of atherosclerosis and one of the systemic markers of inflammation, C-reactive protein(CRP), is associated with extent of coronary artery disease and risk of coronary events. We assessed the time response of CRP response after coronary angioplasty and it's influence on the clinical restenosis in angina patients. Materials and Methods: Patients included 36 angina patients undergoing single vessel angioplasty. Levels of CRP were measured before and 12, 24, 48, and 72 hours after angioplasty. Clinical restenosis was assessed at 6 months after procedure. Results: Baseline CRP level was $0.30{\pm}0.01$ mg/dL in stable and $0.46{\pm}0.28$ mg/dL in unstable angina patients(p<0.05). After angioplasty, CRP level was increased with peak at 24 hour and persisted to 72 hours after angioplasty. At 24 hour after angioplasty, the magnitude of CRP change was $0.32{\pm}0.31$ mg/dL in stable and $0.79{\pm}0.73$ mg/dL in unstable angina patient(p<0.05). The change of CRP level was not associated with troponin-T after angioplasty. In unstable angina patients, clinical restenosis was developed in 8% of patients with low baseline CRP levels and in 50% of those with high baseline CRP levels more than 0.6 mg/dL(p<0.05). Conclusion: In unstable angina patients, inflammatory response is more increased than stable angina patients, and increased inflammatory response effects on the restenosis after coronary angioplasty.

당뇨병환자의 주된 사망 원인은 심장병이다. 당뇨병환자는 동맥경화증이 잘 생기고 이와 관련해 협심증, 심근경색증, 말초혈관질환, 뇌졸중이 잘 생기는 것으로 알려져 있다. 그중에서 관상동맥이 동맥경화증에 의해 막혀 생기는 대표적인 심혈관질환이 바로 협심증과 심근경색이다.

If complete coronary artery occlusion occurs due to severer coronary spasm, malignant arrhythmias can lead to death. Therefore, early screening for coronary artery spasm angina is essential. Among the test methods, the drug injection test through coronary angiography is generally performed. Therefore, the purpose of this study was to evaluate the advantages of ergonovine drug test for vasospasitc angina examination during coronary angiography, such as the relationship between the procedure time, contrast medium usage, and radiation exposure effects of coronary angiography. Follow-up data of 142 patients who underwent coronary angiography and variant angina examination from september 2021 to february 2023 were used. As a result of analyzing contrast usage dose and dose area product and air kerma dose and number of imaging series and procedure time, variant angina examination was statistically significantly higher than coronary angiography. (p<0.001) In conclusion, variant angina examination other than coronary artery angiography are radiologically negative. Therefore, we think it is better to avoid excessive inspection. Nevertheless, in the case of the provocation test, the longer the examination time, the higher the fluoroscopy time and the amount of contrast medium used, so it is better to conduct the test as quickly as possible or shorten it.

Transmycardial laser revascularization has made its position as a sole therapy for patients with chronic angina nonamenable to maximal medical therapy, percutaneous transluminal coronary angioplasty, and coronary artery bypass grafting. We report three cases of transmyocardial laser revascularization as a sole therapy for patients with recurrent angina after CABG.

Postoperative autotransfusion is known as an effective method for blood conservation. We tried to examine whether the autotransfusion of shed mediastinal blood in patients with unstable angina would be valuable for reducing postoperative homologous transfusion by observing the hourly tendency of bleeding and transfusion. Between August and October, 1997, 26 patients with unstable angina underwent coronary arterial bypass surgery by a single surgeon at Asan Medical Center. In retrospective analysis, we found 90% of the patients received homologous transfusions and 85% of them were in the intensive care unit at the same day after operation. In many patients, the cause of transfusion was not anemia but volume replacement. Mean bleeding through the chest tubes was 340 cc for the first 5 hours and 69%(18 pts) showed more than 200 cc of bleeding, the amount generally considered as a initiating point for autotransfusion. Despite the adoption of multiple methods for blood conservation, 90% of the patients needed homologous transfusion. Moreover, many of them had received unnecessary transfusions. We conclude that some kind of blood for transfusion is needed during the immediate postoperative period, and the adoption of postoperative autotransfusion may help in reducing homologous transfusion.

A 65 year-old male had chest pain which was diagnosed as unstable angina needing urgent coronary artery bypass surgery. Physical examination demonstrated signs of severe anemia and hemoglobin level was 5.7 g/dL. Gastrofiberscopy showed a 4 cm sized fungating mass at the lesser curvature with active bleeding. The mass was adenocarcinoma by pathologic examination. Simultaneous coronary artery bypass surgery and total gastrectomy were planned due to bleeding of the mass. Off-pump coronary bypass grafting was done first, followed by total gastrectomy. The postoperative course was smooth. He was discharged from the hospital after 12 days and was on surveillance for 9 months. We report a rare case of simultaneous surgery for angina and gastric cancer.

The clinical concept of coronary artery disease (CAD) has seen a paradigm shift over the last decade. CAD is mostly a progressive disease, and patients with CAD can develop acute coronary syndromes at any point in disease progression. In this clinical context, a new term, "chronic coronary syndrome," was published in the 2019 European Society of Cardiology guidelines, reflecting the importance of early diagnosis and active management. Recent advances have been made in the evaluation of CAD using coronary CT angiography (CCTA). The clinical usefulness of CCTA in patients with stable angina or chronic coronary syndrome begins with the detection of early asymptomatic CAD. The characterization of atherosclerotic plaque and its role in determining treatment strategies for CAD have been demonstrated for all stages of the disease. This review describes the pathophysiology of stable angina to aid in the understanding of the clinical applications of CCTA.

Myocardial bridges as an anatomical arrangement in which an epicardial coronary artery becomes engulfed, for a limited segment, by myocardial fibers. These diseases are recognized primarily because of their systolic narrowing or milking effect as seen on coronary angiography. The most frequent site of myocardial bridging is the middle segment of left anterior descending artery. Myocardial bridges have an ischemic effect capable of causing : angina pectoris, myocardial infarction, ventricular fibrillation, or even sudden death in athletes. We report 2 patients having a milking effect of the middle segment of left anterior descending artery who were suffered from angina. The operation procedure was a simple supraarterial myotomy over the embedded segment of the LAD under cardiopulmonary bypass. Angina and milking effect were disappeared after the operation.

A 60-year-old male was admitted because of dyspnea and angina like chest pain. Noninvasive findings showed a mass at the posterior aspect of the left atrium. The mass was removed under cardiopulmonary bypass. An encapsulated adipose mass, which originated from the left atrium without any invasion to the pericardium, was completely excised. Histological examination showed mature adipose tissue with partial necrosis, confirming the diagnosis of lipoma. We report a rare of case of massive left atrial lipoma occupying the pericardial space.
