May guide cardiac monitoring in severe SAH; leaves open whether neuroprotection reduces myocardial injury.
What are the independent predictors of myocardial necrosis (troponin elevation) in patients with subarachnoid hemorrhage?
The severity of neurological injury, as measured by the Hunt-Hess grade, is a strong independent predictor of myocardial necrosis after subarachnoid hemorrhage, supporting a neurally mediated mechanism for cardiac injury.
Tung et al. (2004) studied this question.
