Coronary artery disease (CAD) narrows vessel lumens at the sites of atherosclerosis, increasing the risk of myocardial ischemia or infarction. Early and accurate diagnosis of CAD is crucial to significantly improve prognosis and management. CT angiography (CTA) is a noninvasive imaging technique that enables assessment of vascular structure and stenosis with high resolution and contrast. Coronary CTA is useful in the diagnosis of CAD. Recently, the CAD-reporting and data system (CAD-RADS), a diagnostic classification system based on coronary CTA, has been developed to improve intervention efficacy in patients suspected of CAD. While the CADRAD is based on CTA, it includes borderline categories where interpreting the coronary artery status solely based on CTA findings may be challenging. This review introduces CTA findings that fall within the CAD-RADS categories that necessitate additional tests to decide to perform invasive coronary angiography and discusses appropriate management strategies.

Early detection of potential asymptomatic coronary artery disease is very important, as patients with sudden cardiac death often do not show symptoms such as chest pain or motor dyspnea. Coronary CT angiography (CCTA) has long been unjustified as a screening tool for asymptomatic patients because of the risks posed by radiation exposure. However, there are still various opinions regarding the usefulness of CCTA for screening for coronary artery disease (CAD) in asymptomatic healthy individuals or patients. This review investigated the usefulness of coronary artery calcium score and CCTA as screening tests for CAD in asymptomatic healthy individuals or patients through various literature reviews. With the development of CT technology, recent studies have been conducted in asymptomatic CAD patients with a reduced radiation dose of less than 1 mSv. A total of 2.6% of asymptomatic subjects on CCTA found significant CAD over 70%, and it was concluded that screening CCTA for CAD showed prognostic power in predicting the future occurrence of CAD in asymptomatic people. However, after the completion of the current NIH SCOT-HEART 2 study, it may be possible to determine whether CCTA is appropriate as a screening tool for CAD in asymptomatic healthy individuals.

관상 동맥 질환은 관상 동맥 내벽에 플라크(Plaque)가 침착된 결과 혈관이 좁아져서 생기는 질환으로, 혈관이 좁아져 심장으로의 혈류가 감소하고, 혈전이 동맥을 막아 심장 발작을 일으킨다. 본 논문에서는 관상동맥 질환의 객관적 분석을 위한 분할 방법론과 분할된 영역으로부터 정량적 분석 방법을 제안한다. 동맥 단면영상으로부터 정량 분석을 위해 획득한 단면영상을 현미경으로부터 12.5배 배율로 얻었으며, 정량 분석을 위해 혈관의 각 영역을 분할하여 분할영역의 크기, 최대 장축 등의 정보를 추출하였다. 본 논문에서 제시한 알고리즘을 사용하여 수 작업에 의한 혈관 단면 분석을 자동화하면, 3차원적 변화량에 따른 정량분석 결과를 얻을 수 있을 것이다.

The purpose of this study was to investigate the level of knowledge, health belief and sick role behavior, and the influencing factors on them among the patients with coronary artery disease. The study subjects were 168 patients diagnosed as having coronary artery disease at a university hospital during the period from July 1st, to August 31th, 2010. As a results, Based on the mean scores of knowledge about coronary artery disease according to the general characteristics, they were significantly higher in males than in females(p=0.033). The mean scores of health belief were significantly higher according to age decrease(p=0.043). The mean scores of sick role behaviors were significantly higher in females than in males(p=0.006), with their increasing tendency in the age range from 40's to 60's and decreasing tendency in the age over 70's(p=0.015), the group with religion were significantly higher than the one without(p=0.050). In terms of the mean scores of knowledge and sick role behaviors about coronary artery disease according to the related characteristics, there was a significant difference with the time period elapsed after diagnosed as coronary artery disease, frequency of admissions, perception about the disease, information gathering through mass com. but in terms of those of health belief, there was a not significant difference in all the variables. The significantly influencing factors on degree of knowledge by multivariate regression analysis included degree of perception about a disease, scores of sick role behavior, presence of coronary artery diseases in a family or friends, and the time period elapsed after diagnosed as having coronary artery disease. Those on health belief included age and scores of sick role behavior, and those on sick role behaviors included score of knowledge, perception about a disease, age, BMI, and religion. The results showed a significant difference with their general characteristics or coronary artery disease-related factors.

Increased intima-media thickness(IMT) of the common carotid artery is an early marker of atherosclerosis and a powerful predictor of coronary and cerebrovascular diseases. The purpose of this study was to evaluate the correlation between carotid artery IMT and cardiovascular risk factors. Total 134 adult were performed with Ultrasonography to measure IMT at common carotid artery, the physical measurements and blood tests, the following results were obtained. As a result, IMT showed higher value in male IMT than female IMT. And, the IMT increased according to the age increased. Also, TC and AI have positive significant correlation with IMT. In Conclusion, cardiovascular risk factors with adult are associated with increased IMT of common carotid artery.

수도관을 오래 세월 사용하다보면 파이프에 녹이슬고 물때가 끼면서 막히게 되고 결국에는 터지는 사태까지 발생하게 된다. 사람의 혈관도 마찬가지로 시간이 지날수록 이물질이 침착하면서 점차 좁아져 문제를 발생시킨다. 특히 심장에 혈액을 공급하는 관상동맥이 좁아지거나 막히면 협심증이나 심근경색증 등의 심장질환이 발병한다.

Background: The purpose of this study was to determine whether hand-measured carotid intima-media thickness (IMT) was a reliable and simple tool that could be used to evaluate the severity of stable coronary artery disease (CAD) with normal high-sensitivity C-reactive protein (CRP). Material and Method: We examined left carotid IMTs in 688 patients with stable CAD and excluded 121 patients with abnormally elevated hs-CRP ($\geq$0.5 mg/dL). We sought to determine the association between risk factors and the severity of stable CAD and carotid IMT in 567 patients who were divided into lower and higher groups based on the median value. Patients underwent a coronary artery angiogram and had at least significant stenosis (>50% of the original luminal diameter involving one or more major coronary artery). Result: Of the 567 patients, 300 (52.9%) were in the lower IMT group and 267 (47.1%) were in the higher IMT group; the median value was 0.76 mm. By multivariable logistic regression analysis, the following groups were different: older age (~49 vs. 70~ years, respectively; OR=6.552), high FBS (~99 vs. 120~ mg/dL; OR=1.713) and severity of CAD (1 vessel vs. 2 vessel disease; OR=1.711, 1 vessel vs. 3 vessel disease; OR=1.714). Conclusion: We conclude that there are correlations between increased carotid IMT and severity of CAD in stable angina patients with normal CRP levels.

Arteriosclerosis is a disease in which blood circulation is impaired due to loss of elasticity as blood vessels become narrower, and is a potential cause of recently increasing cardiovascular and cerebrovascular diseases. Carotid ultrasound is used as a predictor of cardiovascular and cerebrovascular diseases by evaluating the degree of atherosclerosis. Therefore, this paper attempted to investigate the correlation between the increase in the thickness of the inner media and various clinical variables in carotid ultrasound. Patients with carotid ultrasound findings were classified into three stages: mild intima thickening, sclerosis, and significant stenosis. CAVI (Carotid Ankle Vascular Index: vascular age) data measured in the degree and physical characteristics of the carotid artery(gender, age, body mass index, blood pressure), blood test(total cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein, creatine phosphokinase, fasting blood sugar), and arteriosclerosis test were collected. It was confirmed that the carotid intima thickness was correlated with variables such as hypertension, hyperlipidemia, and BMI, and also correlated with the risk factors of cardiovascular disease as CAVI increased.
