title: Benefit and safety of enhanced external counterpulsation in treating coronary artery disease patients with a history of congestive heart failure.
abstract: Enhanced external counterpulsation (EECP) is used to noninvasively treat refractory angina patients, including those with a history of heart failure. The International EECP Patient Registry was used to examine the benefit and safety of EECP treatment, including a 6-month follow-up, in 1,957 patients, 548 with a history of heart failure. The heart failure cohort was older, with more females, a greater duration of coronary artery disease, more prior infarcts and revascularizations. Significantly fewer heart failure patients completed the course of EECP, and exacerbation of heart failure was more frequent, though overall major adverse cardiac events (MACE, i.e. death, myocardial infarction, revascularization) during treatment were not significantly different. The angina class improved in 68%, with comparable quality of life benefit, in the heart failure cohort. At 6 months, patients with congestive heart failure maintained their reduction in angina but were significantly more likely to have experienced a MACE end point.
