NettetThe flow gets ejected into the aorta rapidly at mid systole, and is gradually reduced at the end of systole (frame 4). In subjects HFNEF1, HFREF1 and HFREF2, the abnormal recirculating flow patterns, formed during isovolumic contraction, are seen to remain until the end of the systolic phase. Peak flow rate out of LV is reduced in HFREF patients. NettetNormal Coronary Blood Flow. Resting coronary blood flow is roughly 225 ml/min which results in 4- 5% of the total cardiac output. The coronary circulation is in place as only 1/10 mm of the endocardial heart layer is supplied by blood from the chambers. The rest of the heart needs its own nutrition therefore, coronary circulation is important ...
