title: [The quality of life of the patient with unstable angina treated by spinal cord electrical stimulation].
abstract: Quality of life was evaluated in patients with unstable angina before and after surgical therapy with spinal cord electrical stimulation (SCES). Overall 12 patients were evaluated, with quantification of the mean weekly number of anginal attacks, the degree of effort provoking them and the Nottingham Health Profile (NHP). The criteria of inclusion in the study were: angina grade IV, resistant to drug therapy and without indication of surgery. The mean follow-up period was 9.8 +/- 8.2 months. A significant reduction in the weekly number of anginal attacks (preoperative 30.9 +/- 14.5; postoperative 9.6 +/- 8.2; p less than 0.01); improvement in functional class (p less than 0.001), and significant improvement (p greater than 0.05) in the pain, energy, sleep, social isolation and emotional reactions areas of NHP were observed. It was concluded that SCES is a useful procedure in patients with unstable angina untreatable by other medical or surgical methods, as it reduces the number of anginal attacks and increases quality of life of the patients without additional risk.
