Key result
Enhanced External Counterpulsation (EECP) improved angina class in 74% of patients with limiting angina and was well tolerated with a 4.0% rate of adverse experiences.

Does Enhanced External Counterpulsation (EECP) improve angina class and is it safe in a broad cohort of patients with angina?
EECP is safe and effective for improving angina symptoms in a broad, real-world cohort of patients, supporting its generalizability outside of university studies.
May support EECP evaluation in real-world angina; extends prior data to broader cohorts but leaves practice change open pending RCTs.
The present study utilized a cohort of 2,289 consecutive patients enrolled in the Enhanced External Counterpulsation (EECP) Consortium to evaluate whether results of university studies showing EECP safety and effectiveness in treating angina can be generalized. EECP was found to be safe and well tolerated with a 4.0% rate of adverse experiences. Angina class improved in 74% of patients with limiting angina (Canadian Cardiovascular Society, CCS, functional class II-IV), with patients most impaired at baseline demonstrating the greatest improvement (39.5% of patients in CCS III and IV improved 2 or more classes). Efficacy was independent of provider setting or experience, women responded as well as men, and although younger patients demonstrated a greater likelihood of improvement, EECP was effective in patients ranging from 19 to 97 years. Extending the benefit of EECP treatment to a wider range of patients may be indicated based on these findings.

Lawson et al. (2000) conducted a cohort in Angina (n=2,289). Enhanced External Counterpulsation (EECP) was evaluated on Angina class improvement. Enhanced External Counterpulsation (EECP) improved angina class in 74% of patients with limiting angina and was well tolerated with a 4.0% rate of adverse experiences.
