OBJECTIVE: Intradialytic hypotension (IDH) is common in patients on chronic hemodialysis, but knowledge on determinants is still unclear. The present study aims at evaluating the association between IDH and dialytic age (DA) in patients on chronic hemodialysis. METHODS: Between January 2012 and January 2013, 82 patients on chronic hemodialysis for at least 1 year were screened for inclusion in the present study. Of these, 14 were excluded because of advanced heart failure (n.9), history of alcohol/substance abuse (n.1), diagnosis of dementia (n.2), actual instability of clinical conditions requiring hospitalization (n.2). IDH was defined as a decrease in systolic blood pressure ≥20 mmHg or a decrease in mean arterial pressure (MAP) by 10 mmHg associated with clinical events and need for nursing interventions. The number of IDH episodes in 10 consecutive hemodialysis sessions was recorded for each patient. Linear and logistic regressions were adopted to assess the adjusted association between IDH and DA. RESULTS: The mean DA was 92 ± 81. Eleven patients (16%) experienced IDH. DA was associated with IDH (OR = 1.01; 95% CI = 1.01-1.02; p = 0.048), after adjusting for potential confounders. DA was associated with the numbers of IDH events in the unadjusted model (B = 0.02; 95% CI = 0.01-0.03; p = 0.042), after adjusting for age and sex (B = 0.01; 95% CI = 0.01-0.03; p = 0.042) as well as in the multivariable model (B = 0.02; 95% CI = 0.01-0.05; p = 0.045). CONCLUSION: DA is associated with an increased probability of IDH and with increased number of IHD events. Studies are needed to understand the underlying factors of such an association.
