Residual high-grade angina after EECP occurs in those with more severe angina and multivessel disease at baseline and is associated with cardiac events over the next 3 years.
Objective: We evaluated the degree of residual angina on the outcomes of enhanced external counterpulsation (EECP) therapy for chronic stable angina.
Background: Angina refractory to medical therapy is common in the pool of patients who are not completely revascularized by angioplasty or bypass surgery.
Methods: We examined 902 patients enrolled from 1998 to 2001 in the Second International Enhanced External Counterpulsation Patient Registry. Baseline and outcome variables were stratified by the last recorded Canadian Cardiovascular Society class.
Results: Residual Class 3 (12.1%) or 4 (2.3%) angina was uncommon among patients with severe coronary artery disease after treatment with EECP. Prevalence of diabetes, hypertension, dyslipidemia, and heart failure was similar among the anginal post-EECP anginal classes.
