The SAQ scores before surgery and 6 and 42 months after surgery in the (A) TS group (white bars = baseline score; hatched bars = 6 months after TS; black bars = 42 months after TS) and in the (B) TMR group (white bars = baseline score; hatched bars = 6 months after TMR; black bars = 42 months after TMR). *p < 0.05 versus preoperative mean value. (SAQ = Seattle Angina Questionnaire; TMR = transmyocardial revascularization; TS = thoracic sympathectomy.)
