As in other studies, the intra-hospital mortality was significantly associated with advanced age, a lower initial GCS score, chronic arterial hypertension, preexisting heart failure, antihypertensive medication, a lower cholinesterase level, a higher blood glucose level, a larger ICH volume, a lower body temperature, a higher rate of intubated patients, infratentorial localization of ICH, and presence of IVH and hydrocephalus upon admission [1,2,3,4,5,6,9,10,11,13,15,16,17,21]. The gene discussed is BCHE; the disease is Hydrocephalus.
