Name of journal: American journal of hypertensionAbstract: BACKGROUND: Aneurysmal subarachnoid hemorrhage (SAH) continues to be associated with significant morbidity and mortality despite treatment advancements. Although high blood pressure (BP) remains a significant risk factor in aneurysmal SAH and re-rupture, the role of BP parameters and fluctuation in prognostication remains unclear.CONCLUSION: Increased BP and PP variability within the first 24 hours of admission portends a poor discharge disposition for aneurysmal SAH patients.

On bivariate analysis, Hunt Hess score, Fisher grade, intraventricular hemorrhage, external ventricular drain placement, and systolic BP and pulse pressure variability were significantly associated with a poor disposition. Poor disposition was significantly associated with age, Hunt Hess score, intraventricular hemorrhage, and PP variability on multivariate analysis. PP variability remained an independent predictor for poor disposition (OR 1.11, 95%CI 1.02-1.21, p = 0.02) when adjusting for potential confounders.All authors: Armonda RA, Aulisi EF, Chang JJ, Dowlati E, Felbaum DR, Mai JC, Triano MJOriginally published: American Journal of Hypertension. 2021 Feb 04Fiscal year: FY2021Fiscal year of original publication: FY2021Digital Object Identifier: Date added to catalog: 2021-02-18
