In patients with elevated LVEDP and low AOD, with a coronary perfusion pressure (CPP) <20 mmHg, deep T wave inversion in two consecutive leads were more frequently observed. When the CPP was … The coronary arteries originate off of the ascending aorta and continue onto the surface of the heart (the epicardium). When the heart contracts during systole, the contraction compresses the coronary arteries, which prevents perfusion. Therefore, it is only when the heart relaxes, during diastole, that the coronary vessels open up and allow for perfusion; thus CPP is highest during diastole, unlike most other arteries, which experience higher perfusion pressures under systole.
