What are the evidence-based recommendations for preventing aneurysmal subarachnoid hemorrhage (aSAH)?
The evidence-based recommendations for preventing aneurysmal subarachnoid hemorrhage (aSAH) include: Treatment of high blood pressure with antihypertensive medication to prevent ischemic stroke, intracerebral hemorrhage, and cardiac, renal, and other end-organ injury (Class I; Level of Evidence A); Oral nimodipine should be administered to all patients with aSAH (Class I; Level of Evidence A); Hypertension should be treated, and such treatment may reduce the risk of aSAH (Class IIa; Level of Evidence B); Consumption of a diet rich in vegetables may lower the risk of aSAH (Class IIb; Level of Evidence B); and It may be reasonable to offer noninvasive screening to patients with familial (at least 1 first-degree relative) aSAH and/or a history of aSAH to evaluate (Class IIb; Level of Evidence B).
