Abstract:
We analyzed the causes of death in 109 patients who began hemodialysis therapy between 1969 and 1986 at the Akita Kumiai General Hospital. Patients with acute renal failure were excluded from this survey.
The main causes of death were cardiac failure (25.7%), cerebro-vascular accidents (19.3%), infections (17.4%) and sudden deaths (10.1%).
The proportion of deaths due to cardiac failure was relatively high during the first year of dialysis, although very small among the patients who were dialyzed for more them 5 years, and it was greatest among older patients (especially those older than 60 years of age).
The deaths from cerebro-vascular accidents were due predominantly to cerebral hemorrhage. Death due to cerebro-vascular accidents accounted for the largest proportion (45%) of the deaths in patients treated by hemodialysis for more than 5 years. In comparison with the JSDT statistics throughout the country, the proportion was very high among our patients.
The proportion of deaths due to infections was relatively high during the first year of dialysis, although it was very small among the patients who survived more than 5 years. Of the 11 patients who began hemodialysis at the age of 50 years or greater and who died of infection, 6 died of tuberculosis.
Sudden deaths accounted for 30% of the deaths in those patients who were on maintenance hemodialysis for more than 5 years.
These findings emphasize the increasing importance of the prevention of cerebro-vascular accidents (especially cerebral hemorrhage) and sudden death in patients who survive more than 5 years of hemodialysis therapy.
