Abstract

For patients with symptomatic end-stage coronary artery disease, who have had a poor response to percutaneous transluminal coronary angioplasty or coronary artery bypass grafting, transmyocardial revascularization (TMR) seems to be an alternative to relieve disabling ischemic symptoms. The purpose of this study was to evaluate, by cardiopulmonary exercise testing, the cardiopulmonary capacity after TMR.Ten patients were enrolled in the study. None of them showed significant exacerbation in pulmonary function after TMR. Their average aerobic capacity was about 5MET5; a lower anaerobic threshold and high functional aerobic impairment revealed an insufficient cardiopulmonary capacity. The result of testing showed 1 normal(10%),5 abnormal(50%) and 4 inconclusive(40%). Of the 10 patients during testing, 7 had chronotropic incompetence, 4 had inadequate BP response, and 2 had decreased left ventricular function. There was a higher incidence of left ventricular dysfunction in patients with TMR. Results revealed the importance of a comprehensive cardiopulmonary rehabilitation program for patents with TMR, for the improvement of cardiopulmonary and ADL functions.
