Enhanced external counterpulsation (EECP) has been shown to reduce Canadian Cardiovascular Society angina class.This study examines the factors that affect the reduction at 1 year,especially in patients who do not demonstrate an initial response.The data of 2,007 consecutive patients enrolled in the International EECP Patient Registry were analyzed.After 36.6 +/-4.9 h of EECP,angina was reduced by at least one class in 82.7%.At 1 year,35.4% of initial nonresponders and 70.6% ofresponders remained improved by at least one angina class and free of major adverse cardiovascular events.Multivariate predictors of l-year benefit are initial response to treatment (odds ratio 4.5,95% Cl 3.5-5.8),baseline angina class compared with class Ⅳ (odds ratios:class Ⅰ 2.1,CI 0.93-4.81; class Ⅱ 0.62,CI 0.43-0.87; class Ⅲ 0.80,CI 0.62-1.01) and no history of congestive heart failure (odds ratio 1.41,CI 1.14-1.74).
