Low estimated glomerular filtration rate explains the association between hyperhomocysteinemia and in-hospital mortality among patients with ischemic stroke/transient ischemic attack or intracerebral hemorrhage: Results from the Chinese Stroke Center Alliance.

HHcy was associated with in-hospital mortality among the patients with IS/TIA or ICH but this association disappeared after controlling for eGFR, suggesting HHcy was acting as a marker of poor renal function which itself was the predictor of poor outcome. Our results suggest the prevention and management of renal impairment may be an important measure in the reduction of mortality in patients with HHcy after IS/TIA or ICH.
