AHA/ACC Guidelines for Managing Hypertension in Chronic Kidney Disease
Blood Pressure Target
All adults with hypertension and CKD should be treated to a blood pressure goal of less than 130/80 mmHg. 1 This represents a Class I recommendation with strong evidence for the systolic target and applies regardless of CKD stage or albuminuria status. 1
- The SPRINT trial, which included 28% of participants with stage 3-4 CKD, demonstrated that intensive BP management to this lower target provides the same cardiovascular and mortality benefits seen in the overall study population. 1
- This target applies to all CKD stages, with the vast majority of CKD patients having a 10-year ASCVD risk ≥10%, placing them in the high-risk category requiring treatment initiation at BP ≥130/80 mmHg. 1
First-Line Medication Selection
For CKD with Significant Albuminuria
In adults with CKD stage 3 or higher, OR stage 1-2 with albuminuria ≥300 mg/day (or ≥300 mg/g albumin-to-creatinine ratio), an ACE inhibitor is the reasonable first-line choice to slow kidney disease progression. 1 This is a Class IIa recommendation. 1
- If an ACE inhibitor is not tolerated, an ARB may be reasonable as an alternative (Class IIb recommendation). 1
- The threshold of ≥300 mg/day albuminuria is critical—this represents severely increased albuminuria and is the specific population where renin-angiotensin system blockade has demonstrated kidney-protective benefits. 1
For CKD without Significant Albuminuria
For patients with CKD who do not meet the albuminuria threshold of ≥300 mg/day, use standard first-line antihypertensive medication choices (thiazide/thiazide-like diuretics, ACE inhibitors, ARBs, or calcium channel blockers). 1
Medication Algorithm
The AHA/ACC provides a clear decision tree: 1
Assess albuminuria status:
Titrate to BP goal <130/80 mmHg using additional agents as needed 1
Critical Contraindications
Never combine an ACE inhibitor, ARB, and direct renin inhibitor in patients with CKD—this combination is strongly contraindicated. 2, 3
Monitoring Requirements
After initiating or titrating ACE inhibitors/ARBs, check serum creatinine and potassium within 2-4 weeks. 1, 2
Continue ACE inhibitor/ARB therapy unless: 2
- Serum creatinine rises >30% within 4 weeks of starting treatment
- Symptomatic hypotension develops
- Uncontrolled hyperkalemia occurs despite medical treatment
Continue ACE inhibitor/ARB even when eGFR falls below 30 mL/min/1.73 m² unless the above discontinuation criteria are met. 2
During uptitration to BP goal <130 mmHg, use home blood pressure monitoring to avoid hypotension (SBP <110 mmHg). 1
Follow-up every 6-8 weeks until BP goal is safely achieved, then every 3-6 months once stable. 1
Special Population: Kidney Transplant Recipients
After kidney transplantation, treat to BP goal <130/80 mmHg (Class IIa recommendation), with a calcium channel blocker as the reasonable first-line choice based on improved GFR and kidney survival. 1, 3
Dosing Strategy
Start ACE inhibitors/ARBs at low doses and titrate to the highest approved dose that is tolerated, as proven benefits in trials were achieved using these target doses. 2
Common Pitfalls
Diuretics require careful dosing: Inappropriately low doses result in fluid retention and treatment failure, while excessively high doses cause volume contraction, hypotension, and worsening renal function. 1, 3
Masked hypertension occurs in up to 30% of CKD patients and increases risk of CKD progression—consider home BP monitoring or ambulatory BP monitoring when office readings seem controlled but clinical progression continues. 1
Instruct patients to hold or reduce antihypertensive doses during illness with decreased oral intake, vomiting, or diarrhea to prevent volume depletion and acute kidney injury. 1
Treatment-resistant hypertension is common in CKD, with prevalence rates of 35-39% using the <130/80 mmHg target, increasing progressively with more advanced CKD stages. 4
