Abstract

Balloon counterpulsation has gained widespread acceptance as a therapy for cardiogenic shock. However, over the past four decades a parallel method of noninvasive counterpulsation, enhanced external counterpulsation (EECP), has been defined and developed. Mechanisms of benefit for this technology continue to emerge and include enhanced coronary and other key target organ perfusion beds. Other mechanisms include angiogenesis and enhanced cellular metabolism. Beyond putative mechanisms there is ample evidence for improved and sustained outcomes in patients with and without left ventricular dysfunction. This evidence comes from long-term registry reports and randomized clinical trials. With respect to heart failure (HF), there is registry, pilot trial, and randomized clinical trial evidence of safety and efficacy. This paper summarizes some of the mechanisms and outcomes of EECP in HF patients and helps to elucidate the role of EECP in the management of patients with chronic HF.

Circulation 2002, 106:1237–1242. This study evaluated 10 patients administered EECP while undergoing diagnostic cardiac catheterization using intracoronary pressure and flow wires and angiographic techniques to assess acute effects. Dramatic increases were seen in diastolic (+ 93%) and mean intracoronary (+ 16%) pressures along with a decrease in systolic pressure (-15%). Average intracoronary peak velocity significantly increased (+ 109%) by Doppler measurement and flow significantly increased (+ 28%) by TIMI frame count. Increases in coronary perfusion together with systolic unloading demonstrate the mechanical assist properties of EECP.

Am J Cardiol 2000, 86:1139–1141. This study compared hemodynamic effects of EECP with those of IABP in 39 acute myocardial infarction patients. Although initially increased, right atrial and pulmonary capillary wedge pressures were unchanged with IABP, then gradually decreased with EECP. EECP, but not IABP, increased cardiac index signi ficantly. Both techniques increased diastolic pressures and decreased systolic pressures and systemic vascular resistance. No adverse events were seen with EECP early after acute myocardial infarction and cardiac catheterization.

No clinically siginificant adverse events occurred during the study. Significant improvements were seen in exercise capacity (peak oxygen uptake and exercise duration) and in quality of life at 1 week and 6 months after completion of EECP. This study led to the initiation of a randomized, controlled clinical trial of EECP in HF (PEECH).
