[Epidural stimulation in the treatment of refractory angina].

Twelve patients with refractory angina pectoris previously treated with angioplasty or coronary bypass and under optimal medical therapy were treated with spinal cord electrical stimulation (SCES) at the C7 to D2 level since 1988. Six patients had a significant improvement of symptoms confirmed by a reduced incidence of chest pain and decreased used of nitroglycerin. Three patients required removal of electrode (heart transplantation, inadequate comprehension and foreign body reaction). These patients did however benefit from the effect of SCES for sometimes. Three patients died. The SCES may improve the quality of life by reducing the incidence of chest pain in patients previously uncontrolled with maximal medical and surgical therapy.
