Enhanced External Counterpulsation (EECP) is a non-invasive method currently used for the treatment of ischemic coronary disease. During EECP therapy three compressive pneumatic cuffs are wrapped to the calves, lower thighs, and upper thighs. The cuffs inflated sequentially during diastole cause retrograde aortic flow, and increased venous return. During end diastole, the cuffs rapidly deflate, resulting in unloading of the left ventricle and a decrease in systolic blood pressure. In addition there is also evidence that EECP improves endothelial function. Endothelial dysfunction with imbalance of vasodilatory and vasoactive substance is thought to contribute to elevated blood pressure. This leads us believe that EECP, although not used at present for patients with Resistant HTN, may represent a novel, valuable and untapped therapy.
