Purpose To determine the association between arterial systolic blood pressure values at the beginning and at the end of a hemodialysis (HD) session in intradialytic hypertension patients. Methods This study evaluated the arterial systolic blood pressure patterns in 154 chronic kidney failure patients; among these patients, 18 were identified as having intradialytic hypertension. In the patients with intradialytic hypertension, four consecutive HD sessions were analyzed in which the systolic, diastolic, mean, and pulse blood pressures were automatically determined every 30 min. Results A linear relationship was revealed between the systolic blood pressure levels measured after 30 min and those obtained after 240 min of HD ( r  = 0.3894, p  = 0.001). This association became stronger after 90 min ( r  = 0.5471; p  < 0.001), indicating that for intradialytic hypertension patients, systolic blood pressure values at the beginning of HD were correlated with systolic blood pressure values at the end of the session. Conclusions For intradialytic hypertension patients, values obtained at the end of HD are correlated with the initial values. This information could facilitate planning and earlier treatment.
