Coronary Blood Flow To Time Chart The coronary flow is biphasic there is a small peak of flow during systole then an interruption and then another longer taller peak of greater flow during diastole Hoffman Buckberg 1976 are usually credited with this diagram which plots the coronary blood flow on the same time axis as LV and aortic pressure Wiggers style
Coronary circulation is the circulation of blood in the arteries and veins that supply the heart muscle myocardium Coronary arteries supply oxygenated blood to the heart muscle Cardiac veins then drain away the blood after it has been deoxygenated Adequate blood flow through the coronary vessels is critical to avoid ischemia and maintain the integrity of the myocardial tissue The heart is highly metabolically active and boasts the highest oxygen consumption by mass of any organ

Although blood flow usually is thought of in terms of driving pressure and vascular resistance the complexities of coronary flow do not follow this simple logic The present data help us look at coronary flow especially in LVH in a new and useful light Future experiments examining how known acute alterations in ventricular function affect Time s 0 0 0 4 0 8 1 2 Systole Diastole Systole ETP April 24 26 2014 Unique aspects of the coronary circulation Regulation of Coronary Blood Flow Introduction Control of Coronary Resistance Vessels Autoregulation Pressure Flow Relation Hemodynamic Effects of a Coronary Stenosis Duncker Bache Physiol Rev 2008 Van de Hoeff et al J Mol Cell Cardiol 2012
