BackgroundEarlier studies provided considerably variable estimates on the prevalence and control rates of hypertension in haemodialysis because of their heterogeneity in definitions and blood pressure (BP) measurement techniques applied to detect hypertension.Materials And MethodsIn this cross-sectional study, 116 clinically stable haemodialysis patients from 3 dialysis centres of Northern Greece underwent home BP monitoring for 1 week with the validated automatic device HEM-705 (Omron, Healthcare). Routine BP recordings taken before and after dialysis over 6 consecutive sessions were also prospectively collected and averaged. Hypertension was defined as: (a) 1-week averaged home BP ≥ 135/85 mm Hg; (b) 2-week averaged predialysis BP ≥ 140/90 mm Hg; and (c) 2-week averaged postdialysis BP ≥ 130/80 mm Hg. Participants on treatment with ≥1 antihypertensives were also classified as hypertensives.ResultsThe prevalence of hypertension was 88.8% by home, 86.2% by predialysis and 91.4% by postdialysis BP recordings. In all, 96 participants (82.7%) were being treated with an average of 2.0 ± 1.1 antihypertensive medications. Among drug-treated participants, 32.6% were controlled by home, 50.5% by predialysis and 45.3% by postdialysis BP recordings. In multivariate logistic regression analysis, greater use of antihypertensive medications and postdialysis overhydration, assessed with bioimpedance spectroscopy, were both independently associated with higher odds of inadequate home BP control.ConclusionsThis study shows that the prevalence, but mainly the control rates of hypertension in patients on haemodialysis, differs between peridialytic and interdialytic BP recordings. Therefore, the wider use of home BP monitoring may improve the determination of BP control status in this high-risk population.© 2020 Stichting European Society for Clinical Investigation Journal Foundation.
