Altered endothelin receptor expression and affinity in spontaneously hypertensive rat cerebral and coronary arteries. [PDF]

PLoS ONE, 2013
BACKGROUND: Hypertension is associated with arterial hyperreactivity, and endothelin (ET) receptors are involved in vascular pathogenesis. The present study was performed to examine the hypothesis that ET receptors were altered in cerebral and coronary ...

Single cell analysis of early progenitor cells that build coronary arteries

Nature, 2018
Arteries and veins are specified by antagonistic transcriptional programs. However, during development and regeneration, new arteries can arise from pre-existing veins through a poorly understood process of cell fate conversion.

Coronary Artery Spasm [PDF]

Journal of Cardiac Surgery, 1980
Coronary artery spasm is a transient reduction in lumen diameter of an epicardial coronary artery of sufficient degree to produce objective evidence of myocardial ischemia in the absence of any significant increase in heart rate or blood pressure. In this article are summarized pathophysiological observations, the coronary angiographic anatomy of ...

Investigation of human coronary arteries and heart ventricles mode of deformation and haemodynamics

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011
Mechanical properties of coronary arteries and heart tissues, computer 3D models of CA and heart ventricles were investigated. Numerical analysis of coronary arteries and heart ventricles mode of deformation and haemodynamics was made.

A Recurrent CNN for Automatic Detection and Classification of Coronary Artery Plaque and Stenosis in Coronary CT Angiography [PDF]

IEEE Transactions on Medical Imaging, 2018
Various types of atherosclerotic plaque and varying grades of stenosis could lead to different management of patients with a coronary artery disease. Therefore, it is crucial to detect and classify the type of coronary artery plaque, as well as to detect

Apelin Does Not Impair Coronary Artery Relaxation Mediated by Nitric Oxide-Induced Activation of BKCa Channels

Frontiers in Pharmacology, 2021
Apelin-APJ receptor signaling regulates vascular tone in cerebral and peripheral arteries. We recently reported that apelin inhibits BKCa channel function in cerebral arteries, resulting in impaired endothelium-dependent relaxations.

Single Coronary Artery

Journal of the American College of Cardiology, 2009
![Figure][1] As part of the workup for pulmonary hypertension, a 59-year-old man underwent coronary angiography. This demonstrated a single coronary artery arising from the right sinus of valsalva, which gave off 3 branches that supplied the entire left ventricle.

Variations in coronary artery diameter: a retrospective observational study in Indian population

Heart Vessels and Transplantation, 2022
Objective: The diameter of coronary arteries varies greatly among general population. The knowledge of variations in coronary arteries helps the clinicians to define abnormalities and plan the treatment. Hence, the present study was aimed to study common

Diagnosis and Management of Anomalous Coronary Arteries with a Malignant Course

Interventional Cardiology: Reviews, Research, Resources, 2019
Although the prevalence of anomalous coronary artery from the opposite sinus (ACAOS) in the general population is low, more frequent use of invasive and non-invasive imaging to rule out coronary artery disease has seen an increase in absolute numbers of ...
