Myocardial blood flow in patients with sepsis [PDF]

Physiological Reports
The high mortality of systemic infection results from its associated cardiovascular depression. Cardiac depression typically normalizes if the patient recovers from the infection, but recent studies suggest that these patients have an increased long‐term

Changes in myocardial blood flow and microvascular resistance in patients with coronary artery disease undergoing transcatheter aortic valve implantation [PDF]

Open Heart
Background Severe aortic stenosis (AS) causes a pathophysiological cascade, which impairs myocardial blood flow. This effect is exacerbated in the presence of coronary disease (CAD).

Needle-free myocardial blood flow and reserve quantification using artificial intelligence-enhanced coronary sinus flow magnetic resonance imaging with exercise cardiovascular magnetic resonance [PDF]

Journal of Cardiovascular Magnetic Resonance
: Background: Quantification of coronary sinus (CS) flow has been used with pharmacologic stress as a non-invasive surrogate of global myocardial blood flow and coronary flow reserve (CFR).

Circulating Ectonucleotidases Signal Impaired Myocardial Perfusion at Rest and Stress

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background Ectonucleotidases maintain vascular homeostasis by metabolizing extracellular nucleotides, modulating inflammation and thrombosis, and potentially, myocardial flow through adenosine generation.

Phosphomimetic modulation of eNOS improves myocardial reperfusion and mimics cardiac postconditioning in mice. [PDF]

PLoS ONE, 2014
Myocardial infarction resulting from ischemia-reperfusion injury can be reduced by cardiac postconditioning, in which blood flow is restored intermittently prior to full reperfusion.

Microcirculatory Function in Nonhypertrophic and Hypertrophic Myocardium in Patients With Aortic Valve Stenosis

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2022
Background Left ventricular hypertrophy (LVH) has often been supposed to be associated with abnormal myocardial blood flow and resistance. The aim of this study was to evaluate and quantify the physiological and pathological changes in myocardial blood ...

Regional Myocardial Blood Flow* [PDF]

Journal of Clinical Investigation, 1967
A method is described which measures the local effectiveness of the myocardial circulation, expressed as a clearance constant. Uniform clearance constants have been demonstrated in the normal canine and human myocardium. A distinct difference in clearance constants has been demonstrated between the normal canine myocardium and areas of naturally ...

Persistent Coronary Vasomotor Tone During Myocardial Ischemia Occurs at the Capillary Level and May Involve Pericytes

Frontiers in Cardiovascular Medicine, 2022
BackgroundThere is persistent coronary vasomotor tone during myocardial ischemia, despite ongoing coronary arteriolar dilatation. The mechanism underlying this vasodilatory tone, which can be unmasked by coronary vasodilators, is unclear. We hypothesized

Prior SARS‐CoV‐2 Infection Is Associated With Coronary Vasomotor Dysfunction as Assessed by Coronary Flow Reserve From Cardiac Positron Emission Tomography

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2022
Background Cardiovascular complications from COVID‐19 contribute to its high morbidity and mortality. The effect of COVID‐19 infection on the coronary vasculature is not known.

Insulin and myocardial blood flow [PDF]

Cardiovascular Research, 2003
The renaissance of glucose-insulin-potassium infusion (GIK) as a treatment of acute myocardial infarction both in diabetic and nondiabetic subjects has raised new interests to clarify the effects and mechanisms of insulin on myocardium. Although the action of insulin on substrate metabolism is quite well studied in heart, the cardiovascular effects ...
