Experiences of Undergoing Enhanced External Counterpulsation in Patients With Refractory Angina Pectoris: A Qualitative Study.

Abstract

Enhanced external counterpulsation (EECP) is a noninvasive treatment recommended for patients with refractory angina pectoris (RAP), which generally includes 35 one-hour sessions over 7 weeks. No study has described how patients experience the time before, during, and between sessions, as well as the time after EECP treatment. The aim of this study was to describe how patients with RAP experience EECP treatment. Semistructured interviews took place with 15 strategically selected patients (11 men, 58-91 years old) who had finished 7 weeks of EECP at the 2 existing EECP clinics in Sweden. Data were analyzed using inductive qualitative content analysis. The results were divided into 4 content areas, each comprising 3 categories: (1) experiences before EECP was initiated comprised uncharted territory, being given a new opportunity, and gain insight; (2) experiences during EECP sessions comprised physical discomfort, need of distraction, and sense of security; (3) experiences between EECP sessions comprised physical changes, socializing, and coordinating everyday life; and (4) experiences after 1 course of EECP treatment comprised improved physical well-being, improved mental well-being, and maintaining angina in check. Enhanced external counterpulsation was perceived as an unknown treatment option among these patients with RAP. Nurses should emphasize education before and during treatment based on individualized care needs to improve knowledge and treatment experience, as well as prevent discomfort. There is a great need to increase the awareness of EECP among healthcare professionals because it can improve the life situation for patients with RAP.
