Blood pressure and mortality in U.S. veterans with chronic kidney disease: a cohort study
Insights
The ideal blood pressure (BP) for patients with chronic kidney disease (CKD) appears to be 130-159/70-89 mm Hg. Achieving lower diastolic BP may increase mortality risk in CKD patients.
Area of Science:
- Nephrology
- Cardiovascular Medicine
- Epidemiology
Background:
- The optimal blood pressure (BP) target for reducing mortality in non-dialysis-dependent chronic kidney disease (CKD) patients remains uncertain.
- Understanding BP associations with mortality is crucial for managing CKD patients.
Purpose of the Study:
- To investigate the relationship between combined systolic BP (SBP) and diastolic BP (DBP) levels and all-cause mortality in a large cohort of US veterans with CKD.
Main Methods:
- A historical cohort study was conducted from 2005-2012, including 651,749 US veterans with CKD.
- BP was categorized into 96 combinations of SBP and DBP.
- Time-dependent Cox models were used to analyze associations with all-cause mortality, adjusting for confounders.
Main Results:
- The lowest adjusted mortality rates were observed in patients with SBP of 130-159 mm Hg and DBP of 70-89 mm Hg.
- Conversely, very high or very low SBP and DBP were associated with the highest mortality rates.
- Moderately elevated SBP with DBP ≥70 mm Hg showed lower mortality than ideal SBP with DBP <70 mm Hg.
Conclusions:
- The optimal BP range for CKD patients is suggested to be 130-159/70-89 mm Hg.
- Prioritizing ideal SBP at the cost of suboptimal DBP may not be beneficial for mortality outcomes in CKD.
- Study limitations include a predominantly male cohort, missing proteinuria data, and inability to establish causality.
Background:
The ideal blood pressure (BP) to decrease mortality rates in patients with non-dialysis-dependent chronic kidney disease (CKD) is unclear.
Objective:
To assess the association of BP (defined as the combination of systolic BP [SBP] and diastolic BP [DBP] at the individual level) with death in patients with CKD.
Design:
Historical cohort between 2005 and 2012.
Setting:
All U.S. Department of Veterans Affairs health care facilities.
Patients:
651 749 U.S. veterans with CKD.
Measurements:
All possible combinations of SBP and DBP were examined in 96 categories from lowest (<80/<40 mm Hg) to highest (>210/>120 mm Hg), in 10-mm Hg increments. Associations with all-cause mortality were examined in time-dependent Cox models with adjustment for relevant confounders.
Results:
Patients with SBP of 130 to 159 mm Hg combined with DBP of 70 to 89 mm Hg had the lowest adjusted mortality rates, and those in whom both SBP and DBP were concomitantly very high or very low had the highest mortality rates. Patients with moderately elevated SBP combined with DBP no less than 70 mm Hg had consistently lower mortality rates than did patients with ideal SBP combined with DBP less than 70 mm Hg. Results were consistent in subgroups of patients with normal and elevated urinary microalbumin-creatinine ratios.
Limitation:
Mostly male patients, inability to establish causality, and large number of patients missing proteinuria measurement.
Conclusion:
The optimal BP in patients with CKD seems to be 130 to 159/70 to 89 mm Hg. It may not be advantageous to achieve ideal SBP at the expense of lower-than-ideal DBP in adults with CKD.
