Introduction: Prior observational studies conducted in the hemodialysis population have suggested a reverse association between dialysis‐unit blood pressure (BP) and mortality. The present study aimed to investigate the prognostic association of home versus dialysis‐unit BP with all‐cause mortality in hemodialysis patients. Methods: At baseline, 146 patients receiving maintenance hemodialysis underwent assessment of their BP with the following methods: (i) 2‐week averaged routine predialysis and postdialysis BP measurements; (ii) home BP monitoring for 1 week that included duplicate morning and evening BP measurements with the use of validated devices. Results: Over a median follow‐up period of 38 months (interquartile range [IQR]: 22–54), 44 patients (31.1%) died. In Kaplan–Meier curves, predialysis and postdialysis systolic BP (SBP) was not associated with all‐cause mortality, while home SBP appeared to be of prognostic significance (log rank p = 0.029). After stratifying patients into quartiles, all‐cause mortality was lowest when home SBP was ranging from 128.1 to 136.8 mmHg (quartile 2). In univariate Cox regression analysis, using quartile 2 as a referent category, the risk of all‐cause mortality was 3.32‐fold higher in quartile 1, 1.53‐fold higher in quartile 3 and 3.25‐fold higher in quartile 4. The risk‐association remained unchanged after adjustment for several confounding factors (adjusted hazard ratio: 4.79, 1.79, 3.63 for quartiles 1, 3, and 4 of home systolic BP, respectively). Conclusion: Our findings suggest that among hemodialysis patients, 1‐week averaged home SBP is independently associated with all‐cause mortality. In sharp contrast, SBP recorded either before or after dialysis over 2 weeks is not prognostically informative. [ABSTRACT FROM AUTHOR]
