Primer: practical approach to the selection of patients for and application of EECP

Enhanced external counterpulsation, a noninvasive treatment that involves the sequential inflation of three sets of lower-extremity cuffs during diastole, can reduce the severity and frequency of angina pectoris. Here, Michaels et al. review the experience from the International EECP Patient Registries to evaluate the therapy's safety and efficacy, and provide a practical guide to the selection of patients and application of enhanced external counterpulsation.
