Webcontractility as the main effect is assumed to be due to improved coronary perfusion in dias - tole. Therefore, patients in scenarios, in which contractility is lost such as during prolonged ... LV distension and increased LVEDP. In those scenarios, the patient often is already in the catheterisation laboratory or has to be moved there anyway ... 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. CPP ca… plumbers renton washington
