There are many patients in whom repeat (or initial) PTCA and/or CABG are not appropriate and in whom aggressive medical therapy still fails to maintain a quality of life that patients are comfortable with.EECP is one of several new treatment alternatives for such patients.In our initial studies,18 patients were treated with EECP for 1 hour daily for a total of 36 hours.All 18 patients experienced substantial improvements in anginal symptoms after EECP.Thallium-201 stress testing showed a complete resolution of ischemic defects in 12 patients (67%),a decrease in the area of ischemia in 2 patients (11%),and no change in 4 patients (22%).
