Structural constrained virtual histology staining for human coronary imaging using deep learning [PDF]

arXiv, 2022
Histopathological analysis is crucial in artery characterization for coronary artery disease (CAD). However, histology requires an invasive and time-consuming process. In this paper, we propose to generate virtual histology staining using Optical Coherence Tomography (OCT) images to enable real-time histological visualization.

Progression of Coronary Artery Calcium and Incident Heart Failure: The Multi-Ethnic Study of Atherosclerosis. [PDF]

, 2017
BackgroundAlthough the association between coronary artery calcium (CAC) and future heart failure (HF) has been shown previously, the value of CAC progression in the prediction of HF has not been investigated.

An Effect of Spatial Filtering in Visualization of Coronary Arteries Imaging [PDF]

International Journal of Computer Science & Information Technology (IJCSIT), Vol. 2, No. 1, 2009, PP: 35-40, 2011
At present, coronary angiography is the well known standard for the diagnosis of coronary artery disease. Conventional coronary angiography is an invasive procedure with a small, yet inherent risk of myocardial infarction, stroke, potential arrhythmias, and death.

Association between the atherogenic index of plasma and coronary collateral circulation in patients with chronic total occlusion

BMC Cardiovascular Disorders
Background The atherogenic index of plasma (AIP) is considered an independent risk factor for coronary artery disease (CAD). The present study investigated whether AIP correlates with the formation of coronary collateral circulation (CCC) in CAD patients

Associations between hyperhomocysteinemia and the presence and severity of acute coronary syndrome in young adults ≤ 35 years of age

BMC Cardiovascular Disorders, 2021
Background The prevalence of acute coronary syndrome (ACS) continues to increase among young Chinese adults. Homocysteine (HCY) has been suggested as a promoter of atherosclerosis leading to coronary artery disease (CAD).

MPSeg : Multi-Phase strategy for coronary artery Segmentation [PDF]

arXiv, 2023
Accurate segmentation of coronary arteries is a pivotal process in assessing cardiovascular diseases. However, the intricate structure of the cardiovascular system presents significant challenges for automatic segmentation, especially when utilizing methodologies like the SYNTAX Score, which relies extensively on detailed structural information for ...

Fused Segmentation of Geometric Models for Myocardium and Coronary Artery via Medial Axis [PDF]

arXiv, 2017
Coronary arteries and their branches supply blood to myocardium. The obstruction of coronary arteries results in significant loss of myocardium, called acute myocardial infarction, and the number one cause of death globally. Hence, quantification of the regional amount of heart muscle subtended by obstructed coronary arteries is of critical value in ...
