We highlight the presence of a calcified mass in the left main coronary artery without significant atherosclerosis seen in the other coronary arteries or in the peripheral large arteries. In our view, the calcified character of the obstruction and the calcification of the aortic valve are characteristic of a variant type of coronary artery disease (CAD) not associated with the same risk factors...
Acetylcholine causes endothelium-dependent dilation of normal arteries in most animal species. The effect of acetylcholine on normal human coronary arteries is controversial. Pathologic studies and epicardial echocardiography have shown that diffuse atherosclerosis is often present despite angiographic evidence of discrete coronary artery disease (CAD). Therefore, we postulated that acetylcholi...
OBJECTIVES To identify factors that influence graft disease and native coronary arteries progression disease and prognostic implication of this process. BACKGROUND Unsolved problem in CABG patients is progression of the disease in bypass grafts and native coronary arteries. METHODS Data from 102 patients with CABG, who underwent re-coronarography, were analyzed: - Pre and post-operative var...
Introduction: Human studies have shown that patients with cardiovascular diseases have worse periodontal status. Therefore, this study aimed to investigate the periodontal health in patients with coronary heart diseases who underwent angiography. Methods: In this cross-sectional study, 135 patients with coronary artery disease participated who underwent angiography. Periodontal indices were a...
The vessels that bring blood to the heart are called the coronary arteries. They are like narrow tubes. A fatty substance called plaque can build up in these arteries and make them narrow, so less blood gets to the heart. This is called coronary artery disease. If you have coronary artery disease, your heart isn't getting the blood and oxygen it needs to work like it should. Coronary artery dis...
The coronary arteries are diffusely involved by atherosclerotic plaques in fatal acute myocardial infarction (AMI). The degree of luminal narrowing may vary but plaques are present in practically every millimeter of extramural coronary artery. Usually the lumens of at least two of the three major coronary arteries are narrowed >75% by old plaques in patients who die suddenly (<6 hours) from car...
Background: Atherosclerosis generally occurs in the blood vessels with angulation or curvature, however, association between coronary bifurcation angle and coronary artery disease needs to be further clarified when compared to normal patients. Objectives: The aim of this study is to determine the relationship between left coronary bifurcation angle and development of coronary artery disease whe...
detection of causes of sudden natural death is a major problem of physicians and exact inspection of rare causes of sudden death reduces numbers of white autopsies and helps to well performance of justice. anomalous origin of coronary arteries are one of these rare cases that mostly in infants leading to death due to ischemia and heart failure , and sometimes survive until adulthood and attenti...
BACKGROUND Perinatally HIV-infected adolescents may be susceptible to aggregate atherosclerotic cardiovascular disease risk, as measured by the Pathobiological Determinants of Atherosclerosis in Youth (PDAY) coronary arteries and abdominal aorta risk scores, as a result of prolonged exposure to HIV and antiretroviral therapy. METHODS AND RESULTS Coronary arteries and abdominal aorta PDAY scor...
size and have a complex 3-dimensional (3D) trajectory around the heart. Furthermore, they present a complex motion resulting both from cardiac contraction and respiration. Currently, there are two techniques which compete for such noninvasive coronary imaging: MR and CT. Noninvasive coronary artery imaging by MR (MRCA) was introduced almost 20 years ago [5] and has steadily evolved over time. T...
