Abstract

BACKGROUND AND OBJECTIVES: Although ambulatory BP recordings are found to be superior to dialysis unit recordings in predicting outcomes, ambulatory BP are difficult to obtain in the day-to-day treatment of hemodialysis patients. Home BP agree well with ambulatory BP, but the prognostic significance of home BP recordings is unknown in hemodialysis patients. This study ascertained the role of home BP in predicting all-cause and cardiovascular mortality. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: A prospective cohort study was conducted in 150 patients who were on chronic hemodialysis dialyzing at four university-affiliated units. BP was self-measured at home for 1 wk, for an interdialytic interval by ambulatory recording, and by "routine" and standardized methods in the dialysis unit for 2 wk. Patients were followed for a median of 24 mo to assess the end points of all-cause and cardiovascular mortality. RESULTS: Cardiovascular death occurred in 26 (17%) patients and death in 46 (31%) patients. A 1-SD increase in systolic BP increased the risk for death by 1.35 (95% CI 0.99 to 1.84) and in diastolic BP by 1.40 (95% CI 1.03 to 1.93) for home BP and between 0.97 to 1.19 (P > 0.20) for all-cause mortality for dialysis unit BP recording. A dose-response relationship between increasing quartiles of home BP and all-cause mortality and cardiovascular mortality was seen. CONCLUSIONS: Self-measured systolic BP of 125 to 145 mmHg and of 115 to 125 mmHg by ambulatory BP is associated with the best prognosis in hemodialysis patients.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
