RESUMEN
BACKGROUND: As the guidelines and evidence for the use of electroconvulsive therapy (ECT) in patients with a recent or past history of stroke are unclear, ECT tends to be avoided in this population. AIM: To give a systematic review the literature on the risk and incidence of cerebrovascular accidents after ECT in these patients. METHOD: A systematic literature search was performed according to the PRISMA guidelines in PubMed and in the Cochrane Library. Publications in which ECT was applied in patients with a history of stroke were included by using specific MeSH terms. RESULTS: The following 19 articles met the criteria for review: 1 wide-scale prospective study, 1 small-scale prospective study with a control group, 3 small-scale retrospective studies, and 14 case reports. In the vast longitudinal Danish study, ECT was not associated with an elevated risk of recurrent stroke. Similarly, none of the other studies found the risk to be raised. CONCLUSION: Despite the limited number of prospective studies and the methodological discrepancies in the reports, ECT does not seem to be associated with an elevated risk of recurrent stroke. This review supports the safe use of ECT in patients with a recent or past history of stroke, if prior neurologic and cardiovascular assessments are being performed, as well as monitoring during the treatment.
