introduction: doppler ultrasonography (dus) is the most preferable method for screening of carotid artery disease in patients undergoing cabg. the purpose of this study was to investigate the frequency of carotid artery disease and determine the relation between known risk factors of atherosclerosis and rate of carotid artery narrowing in order to identify high-risk groups among patients schedu...

A relation between the proximal or distal localisation ofatherosclerotic lesions and 3 anatomical variables (i) the length of the left main coronary artery, (ii) its angle of bifurcation into anterior descending and circumflex arteries, and (iii) the dominant coronary artery, was sought at coronary angiography. Studies were made on 149 angiograms of which 95 had critical stenoses (>50% of vesse...

INTRODUCTION AND OBJECTIVES Risk stratification in non-ST-elevation acute coronary syndrome makes use of clinical variables that can identify patients at an increased risk of complications. Our objective was to identify clinical variables that predict significant stenosis (i.e., >50%) of the left main coronary artery in high-risk patients who have had a first episode of non-ST-elevation acute c...

The relation between the length of the main left coronary artery and the presence of atherosclerosis in its branches or the presence of complete left bundle-branch block was studied by selective coronary arteriography in 43 persons. The length of the main left coronary artery was found to be significantly shorter in patients with coronary atherosclerosis than in subjects without angiographic ev...

Left main coronary artery disease (i.e., greater than or equal to 50% stenosis) was found in 1,477 of 20,137 patients in the Coronary Artery Surgery Study (CAS) registry. Of these patients, 53 (3.6%) were asymptomatic. Asymptomatic and symptomatic patients were similar in regard to 1) severity of left main coronary artery stenosis (67% vs. 70%), 2) extent of proximal coronary artery disease (no...

background: more diagnostic techniques require a better understanding of the forces and stresses developed in the wall of the left ventricle. the aim of this study was to differentiate significant coronary artery disease (cad) patients using a non-invasive quantification of myocardial wall stress in the diastole phase. methods: sixty male subjects with sinus rhythm (30 patients with significant...

Exercise testing is commonly used to evaluate patients with coronary artery disease who have serious anatomic characteristics. To study the characteristic exercise test variables in patients with left main coronary artery disease, the computerized data base of the Hungarian Institute of Cardiology Exercise Test Laboratory was used. Among 2,378 patients who had undergone a supine bicycle exercis...
