High-resistive … WebJun 18, 2015 · The resulting increase in coronary vascular resistance results in decreased flow though the coronary circulation. Even though the diastolic augmentation peak is higher, the flow though the coronary circulation is still reduced. Put simply, mid-contraction is a stupid time to try to fill your coronaries. Then, the aortic valve closes prematurely.
