Why the study?
Are hypothalamic and myocardial lesions more frequent in patients dying from subarachnoid haemorrhage compared to other intracranial pathology?
Are hypothalamic and myocardial lesions more frequent in patients dying from subarachnoid haemorrhage compared to other intracranial pathology?
Subarachnoid haemorrhage is associated with concurrent histological lesions in the hypothalamus and myocardium, suggesting a sympathetic nervous system mechanism.

Supports sympathetic mechanism for cardiac lesions in fatal subarachnoid haemorrhage; hypothesis-generating and should not yet alter management.
The hypothalamus and myocardium of 12 patients who had died after a subarachnoid haemorrhage, and of six patients who had died from other intracranial pathology were examined. Only in the patients who had died from subarachnoid haemorrhage were histological lesions found in both the hypothalamus and myocardium. The possible significance of these findings is discussed with particular reference to the sympathetic nervous system.
