GOMEZESE, Omar F et al. Treatment of refractory chest angina with spinal electrical stimulator: literature review. Rev. Col. Cardiol. [online]. 2008, vol.15, n.3, pp.127-133. ISSN 0120-5633.

Justification: there is a group of patients with chronic refractory chest angina, who are not ideal candidates for surgical or percutaneous revascularization and who although having a good medical handling continue to experience severe episodes of angina. The spinal electrical stimulator is a neuromodulator used as an alternative to treat these patients. Objectives: to realize a review of scientific literature regarding the spinal electric stimulation in the treatment of chest angina, its mechanism of action, benefits and its cost effectiveness. Materials and methods: using the Cochrane methodology, a search of articles published from January 1980 to January 2007 in Medline using the terms «spinal cord stimulation», was realized. The papers considered most pertinent were selected. Conclusions: the anti-ischemic effect of the electrical spinal stimulator reduces the episodes of chest angina, improves the quality of life and the tolerance to exercise, diminishes the hospital stay and delays the appearance of ischemic signs.
