The study was conducted in 47 patients (34 males, 13 females) with coronary artery disease or suspected coronary artery disease who were underwent SBSE from May 2002 to October 2004 at 115 People Hospital. Results: CAD was presented in 22 patients: among which, 7 cases with lesion of one major branch, 7 cases with two branches and 8 case with three branches of coronary artery. SBSE test was positive in 20/22 patients, overall sensitivity of 91%, specificity of 80% and accuracy of 85%. The sensitivity was greatest for the font interventricle artery (81%), compared to sensitivity for right coronary artery and the left coronary artery was 56% and 31%, respectively (p<0.005). For identifying patients with multivessels CAD, sensitivity 55%, specificity 97% and accuracy 83%. SBSE is a useful tool for evaluating CAD, and identifying both the location and extent of disease.

72 patients (ages of 51+11), male: 66, female: 6 known or suspected coronary artery diseases (CAD), hospitalized in Department of Cardiology of hospital 108, underwent exercise electrocardiogram. Of the patients, exercise electrocardiogram was positive in 16 (22%). The clinical symtoms between negative and positive exercise electrocardiogram were compared. We found that: two important symtoms for indicating exercise electrocardiogram were compared. We found that: two important symtoms for indicating exercise electrocardiagram were typical angina pectoris (44%, p<0.05) and ST-T abnormalities on the electrocardiogram at rest (50%, p<0.1). Of the positive electrocardiogram patients, 9 were carried out of coronarography. Comparison with coronarography (stenosis> 50%), exercise electrocardiogram showed its sensitivity, specifycity and accuracy for diagnosis of were 100%, 50% and 66.7% (respectively).

Various invasive and non-invasive imaging techniques have been used for the diagnosis of coronary artery disease. Despite several limitations, coronary CTA may soon emerge as the initial diagnostic modality of choice for patients with suspected coronary artery disease. However, in routine clinical practice, the role of coronary CTA is not clearly defined even though promising diagnostic accuracy has been demonstrated compared with that of the other non-invasive tests. Herein, we suggest a new paradigm for coronary CTA as an emerging diagnostic tool in routine clinical practice on the basis of our experience and published data.

Angiographic findings were analysed in 22 cases of coronary occlusive disease which were selected from 50 cases of coronary arteriographies done in Department of Radiology, Seoul National Un iversity Hospital from September, 1981 to August, 1984. There were 16 cases of single vessel disease, in which 12 were LAD involvement and 4 were RCA involvement, 2 cases of two vessel and 4 cases of three vessel disease. Site, degree and extent of stenotic involvement in those occlusive coronary diseases were anal ysed with review of literature for selective coronaryarteriography. Since coronary arteriography is the final and accurate examination for the evaluation of occlusive coronary arterial disease, it is expected to be widely used for the diagnosis of occlusive coronary arterial disease which is rapidly increasing recently in this country.

OBJECTIVE: In this paper, an intelligent system using BP neural networks (BPNN) is presented for early detection coronary artery disease (CAD). METHODS: Based on the four features of ECG signals and six basic parameters of patients, BPNN was built and trained. Especially the method which combined feature extraction and classification was discussed. RESULTS: The performance of the intelligent system has been evaluated in 20 samples. The test results showed that this system was effective in detecting CAD. The correct classification rate was about 90% for normal subjects and 100% for abnormal subjects. CONCLUSION: BPNN could quite accurately detect abnormal subjects. Because it is not expensive and noninvasive, it is fit to examine health of the elderly and has good application foreground.

Bilateral coronary arteriovenous fistula (CAVF), arising from both the right and left coronary arteries, are rare. We experienced a 44 years old male patient with bilateral CAVF, and coronary atherosclerosis, whose diagnosis was confirmed by coronary angiography. The hemodynamic result revealed minimal left-to-right shunt. Therefore, only percutaneous coronary artery intervention of the coronary artery stenosis was performed. Here, this rare case is reported, with a review of the literature.
