title: Incidence of strokes and its prognosis in patients on maintenance hemodialysis.
abstract: The incidences of cerebral hemorrhage (CH), cerebral infarction (CI) and subarachnoid hemorrhage (SAH) were examined retrospectively in patients with chronic renal failure on maintenance hemodialysis, followed for 13 years in our 26 satellite dialysis centers. During 10,364 patient-years of experience (PYE), CH developed in 66, CI in 16, SAH in 3 and unclassified stroke in 5 cases. The incidence was 637 per 10(5) PYE for CH and 154 for CI, the former being approximately 5 times and the latter one third of the incidence of CH or CI in the general population in Japan. Forty-six percent of fatal CH cases died within 24 hours and 73% within 3 days after the onset, while 13% of CI deaths died within 24 hours and 26% within 3 days. These data suggest that factors such as the regular use of heparin as an anticoagulant in hemodialysis patients or other inherent factors in these patients may increase vulnerability to CH and decrease the probability of CI.
