    Elevated catecholamine levels after aneurysmal subarachnoid hemorrhage are linked to increased sympathetic activity and poorer patient outcomes.

  • 2

    Catecholamine surges can exacerbate brain injury, increase blood pressure, and contribute to secondary brain injury.

  • 3

    Cardiac dysfunction and arrhythmias are common in patients with catecholamine excess, leading to higher morbidity and mortality.

  • 4

    Metabolic disturbances such as hyperglycemia and electrolyte imbalances are associated with worse outcomes in these patients.

  • 5

    Therapeutic strategies like beta-blockers and calcium channel blockers are being explored to mitigate the effects of catecholamine surges.
