Impact of Enhanced External Counterpulsation on Vascular Hemodynamics and Status

Enhanced external counterpulsation (EECP) is a technique for assisting the circulation by decreasing the afterload of the left ventricle and augmenting the diastolic pressure externally by applying a negative pressure to the lower extremities during cardiac systole. EECP therapy is done by sequential inflation of 3 sets of cuffs wrapped around the lower extremities during diastole and deflation of the cuffs during systole. EECP enhances the aortic diastolic blood flow and coronary perfusion, leading to increased arterial wall shear stress in a pulsatile manner.
