What are the effects of enhanced external counterpulsation on chronic stable angina pectoris?
Enhanced external counterpulsation (EECP) is a non-invasive procedure that has been found to improve exercise tolerance, reduce exercise-induced myocardial ischemia, and improve left ventricular diastolic filling in patients with chronic stable angina pectoris. Several studies have reported improved Canadian Cardiovascular Society angina class in patients with chronic stable angina pectoris following EECP. Additionally, EECP has been found to reduce stress radionuclide coronary perfusion and exercise capacity, improve regional myocardial perfusion, and improve immediate and long-term clinical outcomes in patients with refractory angina pectoris.
