초록 Proper blood pressure (BP) control is an important topic for hemodialysis (HD) patients and accurate BP measurement is mandatory. The authors aimed to investigate which BP measurement method is most appropriate for HD patients and discuss the usefulness of home BP measurement. Subjects that underwent maintenance HD from July 2018 to March 2019 were screened, and 40 patients with available home and ambulatory BP monitoring (ABPM) data were analyzed. Dialysis unit BPs were the averages of pre-, intra-, and post-HD BP during the study period. Home BP was defined as the average of morning and evening BPs. The BPs data used in this study are the average dialysis unit BP and home BP for two weeks, which are closest to the date of ABPM's implementation. ABPM was performed once for 24 hours on the day of no dialysis during the study period. In addition, the characteristics of subjects that experienced or did not experience intradialytic hypotension were compared. Mean patient age was 64.9± 14.4 years and 52.5% were male. Average BPs were as follows: dialysis unit BP, 141.0 ± 17.1 / 54.2 ± 7.7 mmHg; home BP, 135.0 ± 18.8 / 69.8 ± 18.4 mmHg; and ambulatory BP, 129.8 ± 20.9 / 76.2 ± 8.9 mmHg. Significant differences were found between dialysis unit SBP and home SBP (P = 0.002) and ambulatory SBP (P <0.001), and between home SBP and ambulatory SBP (P=0.042). However, no significant difference was observed between ambulatory SBP and evening home SBP (P = 0.719). Intra-HD SBP was not significantly different from home SBP(P=0.906) or ambulatory SBP(P=0.115). Intra-HD SBP might be useful for predicting home BP and ABPM in HD patients. However, regular home BP monitoring is important, because dialysis unit BP alone does not reflect BP status in HD patients.
