Particularities of coronary physiology in patients with atrial fibrillation: insights from combined pressure and flow indices measurements

open access: yesFrontiers in Cardiovascular Medicine, 2023
BackgroundSymptoms suggestive of myocardial ischemia are frequently encountered in patients with atrial fibrillation (AF) even in the absence of obstructive coronary artery disease.

Anatomic and Hemodynamic Plaque Characteristics for Subsequent Coronary Events

open access: yesFrontiers in Cardiovascular Medicine, 2022
ObjectivesWhile coronary computed tomography angiography (CCTA) enables the evaluation of anatomic and hemodynamic plaque characteristics of coronary artery disease (CAD), the clinical roles of these characteristics are not clear.

Multi-vessel coronary disease and percutaneous coronary intervention [PDF]

open access: yesHeart, 2004
The goal of percutaneous coronary intervention (PCI) is to provide a safe, effective, less invasive alternative to coronary artery bypass graft surgery (CABG). When introduced by Andreas Gruentzig 25 years ago, he envisioned the procedure to be a technique that would delay the need for CABG until severe multi-vessel coronary disease was present.

Diabetes mellitus and ischemic heart disease. the role of ion channels [PDF]

open access: yes, 2018
Diabetes mellitus is one the strongest risk factors for cardiovascular disease and, in particular, for ischemic heart disease (IHD). The pathophysiology of myocardial ischemia in diabetic patients is complex and not fully understood: some diabetic ...

Coronary Vessel Development [PDF]

open access: yesArteriosclerosis, Thrombosis, and Vascular Biology, 2003
Development of the coronary vascular system is an interesting model in developmental biology with major implications for the clinical setting. Although coronary vessel development is a form of vasculogenesis followed by angiogenesis, this system uses several unique developmental processes not observed in the formation of other blood vessels.

Biomarkers of coronary endothelial health: correlation with invasive measures of collateral function, flow and resistance in chronically occluded coronary arteries and the effect of recanalization [PDF]

open access: yes, 2016
Objectives: In the presence of a chronically occluded coronary artery, the collateral circulation matures by a process of arteriogenesis; however, there is considerable variation between individuals in the functional capacity of that collateral network ...

Semaphorin3E-PlexinD1 signaling in coronary artery and lymphatic vessel development with clinical implications in myocardial recovery

open access: yesiScience, 2021
Summary: Blood and lymphatic vessels surrounding the heart develop through orchestrated processes from cells of different origins. In particular, cells around the outflow tract which constitute a primordial transient vasculature, referred to as aortic ...

Arteriogenesis versus angiogenesis: similarities and differences [PDF]

open access: yes, 2007
Cardiovascular diseases account for more than half of total mortality before the age of 75 in industrialized countries. To develop therapies promoting the compensatory growth of blood vessels could be superior to palliative surgical surgical ...

Tissue characterization of non-culprit intermediate coronary lesions in non ST elevation acute coronary syndromes

open access: yesThe Egyptian Heart Journal, 2018
Background: Disruption of vulnerable plaques is the most common cause of acute coronary syndromes. Intravascular ultrasound facilitates cross-sectional imaging of coronary arteries.
