A Comparison of Quality of Life Scores in Patients With Angina Pectoris After Angioplasty Compared With After Medical Therapy

Abstract

This was the first study of the relative changes in QOL measures assessed with the use of previously validated and standardized instruments in patients randomly assigned to treatment with PTCA or medical therapy. Patients assigned to PTCA demonstrated a significantly greater improvement in both physical and psychological measures. This improvement was noted in patients whose exercise performance improved and whose angiograms demonstrated an improvement in lesion severity.
