BACKGROUND Enhanced external counterpulsation (EECP) treatment can improve exercise tolerance in patients with ischemic heart disease; however, the possible benefits of EECP in patients with stable heart failure (HF) and left ventricular dysfunction (LVD) are unclear. An open pilot study showed significant increases in exercise tolerance in HF patients undergoing EECP. Thus a larger, controlled...

Enhanced external counterpulsation (EECP) is a noninvasive technique that provides beneficial effects for patients with chronic, symptomatic angina pectoris. However, the direct left ventricular effects of EECP have not been studied invasively. We examined invasive right atrial pressure and left ventricular hemodynamics during EECP. Ten patients referred for diagnostic evaluation underwent left...

A growing number of patients with chronic artery disease suffer from angina, despite the optimal medical management (ie, β-blockers, calcium channel blockers, and long-acting nitrates) and revascularization. Currently, enhanced external counterpulsation (EECP) therapy has been verified as a noninvasive, safe therapy for refractory angina. The study was designed to evaluate the efficacy of EECP ...

and brain natriuretic peptide levels. Unlike the Masuda et al. study, atrial natriuretic peptide levels were unchanged, but brain natriuretic peptide levels decreased after enhanced external counterpulsation treatment as they did in the study of Masuda et al. The authors concluded that enhanced external counterpulsation improves myocardial perfusion, exercise performance and left ventricular di...

This study analyzed the acute effects of enhanced external counterpulsation (EECP) on oxygen uptake (VO2) at rest in adults with symptomatic coronary artery disease (CAD) compared with healthy volunteers. EECP therapy increases exercise tolerance in patients with refractory angina pectoris. This may be attributed, at least in part, to a training effect, but measurement of VO2 during an EECP tre...

BACKGROUND When using a pulsatile left ventricular assist device (LVAD), it is important to reduce the cardiac load variations of the native heart because severe cardiac load variations can induce ventricular arrhythmia. In this study, we investigated the effect of counter-pulsation control of the LVAD on the reduction of cardiac load variation. METHODS A ventricular electrocardiogram-based c...

BACKGROUND Enhanced external counterpulsation (EECP) is a non-invasive technique that has been shown to be effective in reducing both angina and myocardial ischemia in patients not responding to medical therapy and without revascularization alternatives. The aim of the present study was to assess the long-term outcome of EECP treatment at a Scandinavian centre, in relieving angina in patients w...

OBJECTIVE Shear stress may be the most crucial local factor affecting atherogenesis. The present study investigated the effect of exposure to increased shear stress promoted by enhanced external counterpulsation (EECP) on the progression of atherosclerosis and the underlying inflammation-related molecular mechanisms in a porcine model of hypercholesterolemia. METHODS AND RESULTS Hypercholeste...

Background—Mechanisms responsible for anti-ischemic benefits of enhanced external counterpulsation (EECP) remain unknown. This was the first randomized sham-controlled study to investigate the extracardiac effects of EECP on peripheral artery flow-mediated dilation. Methods and Results—Forty-two symptomatic patients with coronary artery disease were randomized (2:1 ratio) to thirty-five 1-hour ...
