Eligibility Criteria

Sex: All

Age: 18+

Healthy Volunteers: Not accepted

Inclusion Criteria:

  • >18 years of age
  • Neuro-imaging confirmed non-traumatic subarachnoid hemorrhage

Exclusion Criteria:

  • Traumatic cause of subarachnoid hemorrhage (e.g. fall, motor vehicle accident, other blunt trauma) as this is a different mechanism of hemorrhage.
  • Other forms of traumatic or non-traumatic intracranial bleed including intracerebral hemorrhage (ICH), subdural hemorrhage, epidural hemorrhage
  • Pregnancy (as the study medication, metoprolol, has FDA Pregnancy Category C rating)
  • Unstable vital signs not amenable to beta-1 adrenergic receptor inhibitor (B1ARi) administration including:
  • Systolic blood pressure < 80 mmHg not stabilized on vasopressor medications
  • Heart rate < 50 bpm associated with hypotension
  • Patients requiring vasopressor agents due to hypotension (SBP <80 mmHg)
  • Other vital sign exclusion at the discretion of the treatment team
  • Previous history of severe heart failure (Stage C or D Heart Failure and/or NYHA Class III or IV)
  • Patient or legally authorized representative unwilling to provide informed consent

Interventions and Outcome Measures

Arms

experimental: Metoprolol (Beta-adrenergic blockade)

Patients will receive metoprolol during the first 72-hours of hospitalization after non-traumatic SAH.

placebo comparator: Placebo

Patients will receive placebo during the first 72-hours of hospitalization after non-traumatic SAH.

Interventions

Metoprolol

Metoprolol Dosing:

Metoprolol Injection (instructions: 5mg, once) Metoprolol Tab (25mg PO, q12 hours, timed to start 1hr after Metoprolol Injection, 6 doses) If unable to take PO medication, Metoprolol Injection (instructions, 5mg q6hrs for 12 doses) Continue for 72-hours of administration unless reaching stopping criteria

Placebo

Placebo Dosing:

Placebo Injection (instructions: 5mL NS, once) Placebo Tab (1 tab PO, q12 hours, timed to start 1hr after placebo injection, 6 doses) If unable to take PO medication, Placebo Injection (instructions, 5mL q6hrs for 12 doses) Continue for 72-hours of administration unless reaching stopping criteria

Primary outcome measure

  • Delta QTc length [ Time Frame: 7 days ]
  • Delta neutrophil activity [ Time Frame: 7 days ]
