Hypertension management in chronic kidney disease: translating guidelines into daily practice

Area of Science:

• Nephrology
• Cardiovascular Medicine
• Public Health

Background:

• Blood pressure (BP) control is crucial for managing chronic kidney disease (CKD).
• The effectiveness of sustained nephrology management on achieving BP goals in non-dialysis CKD patients is not well-established.
• This study investigates the impact of 1-year nephrology management on BP control in incident CKD patients.

Purpose of the Study:

• To evaluate the relationship between 1-year nephrology management and BP control in patients with non-dialysis CKD.
• To identify factors associated with suboptimal BP control despite nephrology management.

Main Methods:

• Historical cohort analysis of 275 incident CKD patients in an academic renal clinic.
• Comparative analysis of BP and proteinuria levels from baseline referral to the 12-month follow-up visit.
• Regression analysis to identify independent predictors of not-at-goal BP at 12 months.

Main Results:

• Mean estimated glomerular filtration rate (GFR) was 42.1 ± 15.5 ml/min/1.73 m², with median proteinuria of 0.20 g/24 hours.
• BP decreased from 148/81 mmHg at baseline to 136/76 mmHg at 12 months, increasing goal achievement from 13.8% to 33.8%.
• Diabetes and higher baseline systolic BP were independent predictors of not-at-goal BP. Patients not at goal had smaller BP reductions but significant decreases in both BP and proteinuria.

Conclusions:

• Sustained nephrology management leads to improved hypertension control in CKD patients.
• Achievement of BP goals remains suboptimal, with high systolic BP and diabetes as primary barriers.
• Further research is needed to clarify the clinical significance of BP and proteinuria changes in patients remaining above target BP levels.
