Coronary anatomy and arteriography in patients with unstable angina pectoris

Left main coronary artery disease in adults younger than 50 years: A comparison with older patients

“…The prevalence of LMCA disease at our institution between January 1, 1996, and January 1, 1999 among patients undergoing coronary angiography for the first time was 3.7%. This rate is comparable to rates found in previous studies [3,5,7,[11][12][13][14]; in those studies the rate of LMCA stenosis found during angiography (using Ն 50% stenosis of the LMCA as the criterion for significant obstruction) varied from 2.5% to 17.5%. The average severity of the stenosis in these 200 patients was 65 Ϯ 15%.…”

Total occlusion of the left main and proximal right coronary artery: Case report and review of the literature

“…It is found more frequently (12-18%) in patients who present with unstable angina [7]. Total occlusion of the LMCA is a rare an- .…”

Epidemiology of Cardiac Disease in Dialysis Patients

“…To complicate the matter further, up to 50% of patients with symptoms of myocardial ischemia may not have CAD (9) (as defined by luminal narrowing of more than 50% of major coronary vessels) as compared to only approximately 20% of patients in the general population with these symptoms (40)(41)(42). The apparently higher prevalence of ischemic heart disease without documented large-vessel epicardial coronary disease in dialysis patients may reflect the combined effects of LVH, anemia, and volume overload in causing increased oxy-gen demand and small-vessel coronary disease in causing decreased oxygen supply.…”
