Background: EECP therapy is a novel adjunct tool used in the treatment of patients (pts) with angina pectoris and congestive heart failure (CHF) who remain symptomatic despite maximum therapy. Methods: 84 consecutive pts referred for EECP were included; of these, 52 pts were recruited and 42 completed a full course of therapy (35 sessions). Pre and post treatment results for changes in functional capacity and severity of symptoms was evaluated. A paired t-test was utilized to evaluate signifi cance of Results: A p-value of <0.05 was considered statistically signifi cant. Results: The mean age of the pts was 72 years (range: 49-94 years). We looked at the 6 minute walk test (6MWT), Duke activity score index (DASI), exercise tolerance in METS, mean anginal episodes per week, systolic blood pressure (SBP), diastolic blood pressure (DBP), and functional class of CHF and angina pectoris. The McNemar`s test for comparison of CCVS/NYHA functional class was performed by combining functional class 1 and 2 (mild) and functional class 3 and 4 (moderate to severe). Pre and post treatment results were obtained. 6MWT: 386.1 vs 426.8 (SE: 7.9), p<0.0001; DASI:4.10 vs 6.3(SE:0.57), p<0.0003; exercise tolerance in METS 2.90 vs. 4.0 (SE 0.23), p<0.0001; mean anginal episodes 12.3 vs. 2.4, (SE:2.18), p<0.0001; NTG use 2.45 vs. 0.47, (SE: 0.78), p<0.01; SBP: 117 vs. 114, (SE:1.5), p<0.05; DBP: 67 vs 66 (SE:0.687), p=NS; Angina Pectoris and CHF(CCVS /NYHA) functional class: 95 percent vs 25 percent, p<0.0001 Conclusions: There was signifi cant improvement in anginal and CHF symptoms in pts completing a full course of EECP therapy. Additionally, there was statistically signifi - cant improvement in number of anginal episodes, DASI, decreased NTG use, increased exercise tolerance in METS, and improvement of angina pectoris/CHF functional class.
