Coronary artery perfusion is dependent upon: A. diastolic pressure B. systolic pressure C. afterload D. systemic vascular resistance (SVR) - A. diastolic pressure Diastolic pressure in the aortic root is higher than left ventricular end-diastolic pressure (LVEDP), the pressure exerted on the ventricular muscle at the end of diastole when the ventricle is full. This enables blood to flow from a higher pressure through open arteries to a lower pressure, a pressure gradient known as coronary a...
