This review traces the evolution of external counterpulsation from its beginning to the early 1990s.The term counterpulsation derives from the dual hemodynamic goals of this treatment:to reduce the afterload of the left ventricle and to augment diastolic pressure.The studies summarized in this review demonstrate clinical benefits in the treatment of angina,acute myocardial infarction,and cardiogenic shock.It has been demonstrated that an external counterpulsation treatment system is highly effective when a series of 3 pneumatic cuffs is wrapped securely around the lower extremities and buttocks,inflating in a distal to proximal sequence,and deflating simultaneously timed to cardiac systole.Sequential inflation augments diastolic perfusion pressure; simultaneous deflation decreases peripheral vascular resistance,significantly decreasing cardiac workload.This method of counterpulsation,EECP,effectively increases myocardial oxygen supply by increasing coronary blood flow and diminishing myocardial oxygen requirements.
