The heart is highly metabolically active and boasts the highest oxygen consumption by mass of any organ. This demand for oxygen is met by the coronary circulation, which is responsible for delivering blood to the myocardium and represents approximately 5% of cardiac output.[1] Adequate blood flow through the coronary vessels is critical to avoid …
Understanding Coronary Blood Flow - Circulation
https://www.ahajournals.org/doi/full/10.1161/circulationaha.105.617183
Article p 1768. In this week’s Circulation, Davies et al 1 used computer analysis of recordings of blood flow and pressure to detect and quantify intracoronary waves and to study coronary flow events in normal subjects and those with left ventricular hypertrophy (LVH). Waves were generated from both ends of the coronary tree.

Introduction. With coronary circulation, coronary comes from the Latin word “coronarius,” meaning "crown." This is because the coronary blood vessels surrounding the heart resembles a little crown! And circulation refers to “the flow of blood.”. So, coronary circulation is the movement of blood throughout the vessels that supply the ...

coronary circulation, part of the systemic circulatory system that supplies blood to and provides drainage from the tissues of the heart. In the human heart, two coronary arteries arise from the aorta just beyond the semilunar valves; during diastole, the increased aortic pressure above the valves forces blood into the coronary arteries and thence into the musculature of the heart.
Regulation of Coronary Blood Flow - PMC
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5966026/
The heart is uniquely responsible for providing its own blood supply through the coronary circulation. Regulation of coronary blood flow is quite complex and, after over 100 years of dedicated research, is understood to be dictated through multiple mechanisms that include extravascular compressive forces (tissue pressure), coronary perfusion pressure, myogenic, …
The coronary circulation and blood flow in left ventricular
https://pubmed.ncbi.nlm.nih.gov/21924273/
The abnormalities of the coronary microcirculation may be unrelated to the degree of LVH and cause a reduction in maximum myocardial blood flow which, in the absence of epicardial stenoses, is suggestive of CMD. There is no technique that enables direct visualization of coronary microcirculation in vivo in humans. Therefore, its assessment ...

The Heart, Part 7: Coronary Circulation. Coronary circulation includes important arteries and veins that perfuse the heart. The blood inside the atria and ventricles does not directly support the heart muscle; the heart has to deliver and drain blood as it does for any other muscle. However, these arteries and veins represent a site-specific ...
