BackgroundTo determine the effect of selective serotonin reuptake inhibitor (SSRI)/selective norepinephrine reuptake inhibitor (SNRI) use on the risk of symptomatic vasospasm and delayed cerebral ischemia (DCI) in patients hospitalized with aneurysmal subarachnoid hemorrhage (aSAH).MethodsRetrospective review of consecutive patients with aSAH at Mayo Clinic, Rochester from January 2001 to December 2013. The variables collected and analyzed included age, sex, SSRI/SNRI use, active smoking, transfusion, modified Fisher score, WFNS grade, and outcome at discharge. Multivariate logistic regression analysis was used to evaluate factors associated with DCI, symptomatic vasospasm, and poor outcome (modified Rankin score 3-6) within 1 year.Results579 [females 363 (62.7%)] patients with a median age of 55 (IQR 47-65) years were admitted with aSAH during the study period. WFNS at nadir was IV-V in 240 (41.5%), and modified Fisher score was 3-4 in 434 (75.0%). 81 (13.9%) patients had been prescribed an SSRI or SNRI prior to admission and all continued to receive these medications during hospitalization. Symptomatic vasospasm was present in 154 (26.4%), radiological infarction in 172 (29.5%), and DCI in 250 (42.9%) patients. SSRI/SNRI use was not associated with the occurrence of DCI (p = 0.458), symptomatic vasospasm (p = 0.097), radiological infarction (p = 0.972), or poor functional outcome at 3 months (p = 0.376).ConclusionsThe use of SSRI/SNRI prior to and during hospitalization is not associated with DCI or functional outcome in patients with aSAH.
