Association of blood pressure increases during hemodialysis with 2-year mortality in incident hemodialysis patients: a secondary analysis of the Dialysis Morbidity and Mortality Wave 2 Study.

ABSTRACT:

Background

Intradialytic increases in blood pressure (BP) can complicate the management of hypertension in hemodialysis (HD) patients. However, the long-term consequences are uncertain. Thus, we sought to determine whether BP increases during HD were associated with greater 2-year mortality in incident HD patients.

Study design

Secondary analysis of a prospective dialysis cohort.

Setting & participants

Incident HD patients in the Dialysis Morbidity and Mortality Wave 2 Study.

Predictors

Changes in systolic BP (SBP) during HD (ie, postdialysis SBP -- predialysis SBP), averaged from 3 HD sessions before enrollment.

Outcome

Time to 2-year all-cause mortality.

Measurements

Cox regression was used to model hazard ratios for mortality associated with ch
