UNLABELLED: Enhanced external counterpulsation (EECP) is a new therapy offered to patients with refractory angina pectoris (AP).
PURPOSE: To assess the effect of EECP on AP, quality of life (QoL) and exercise capacity in a design starting with a control period to avoid the influence of regression-towards-the-mean.
METHODS: Patients were examined two months before EECP, just before, just after, and three and 12 months after EECP. EECP was given for 1 h 5 days a week in 7 weeks. Three sets of pneumatic cuffs were mounted on the lower extremities and inflated sequentially in diastole to 260 mm Hg.
RESULTS: 50 patients were included (male 72%, mean age: 62.5 years). Mean daily AP attacks were reduced during EECP from 2.7 to 0.9 (p < 0.005) and the Canadian Cardiovascular Society classification was reduced by at least 1 class in 82% just after EECP, 79% 3 months and 76% 12 months after EECP (p < 0.0002). Generic (SF36) and disease-specific QoL (Seattle AP questionnaire) improved just after, 3 and 12 months after compared with that before EECP. There was a significant improvement in exercise capacity and exercise-induced chest pain just after, three and 12 months after EECP (p < 0.02). No change was detected during the control period.
CONCLUSIONS: EECP improves generic and disease-specific QoL, angina intensity and exercise capacity in at least 12 months.
