Elevated catecholamine levels after aneurysmal subarachnoid hemorrhage correlate with increased sympathetic nervous system activity, resulting in poorer outcomes and higher mortality. A comprehensive literature review highlighted how catecholamines impact patient prognosis through mechanisms such as exacerbating brain injury and contributing to secondary complications like cardiac dysfunction and metabolic derangements. Effective management strategies include beta-blockers, alpha-adrenergic antagonists, and calcium channel blockers to reduce catecholamine effects.
