β-Blockers in Hypertension with CKD
✅ Pathophysiology: Sympathetic overactivity in CKD drives hypertension, accelerates GFR decline, and increases CV morbidity & mortality.
✅ β-Blockers in CKD:
Cardioselective (Metoprolol, Atenolol) → slow renal disease progression, but less potent than RAAS blockade.
Vasodilating (Carvedilol, Nebivolol) → reduce renal vascular resistance, preserve GFR, slow albuminuria, and provide stronger cardiorenal protection.
Dialysis patients: β-blockers mitigate arrhythmias, reduce arterial stiffness & LVH.
✅ Lipid solubility matters:
Lipophilic (Metoprolol, Carvedilol, Propranolol): hepatic metabolism, CNS pe*******on, not dialyzable → better antiarrhythmic & cardioprotective effects.
Hydrophilic (Atenolol, Nadolol): renally cleared, risk of accumulation, dialyzable → less preferred in CKD.
Amphiphilic (Bisoprolol, Nebivolol): mixed clearance; nebivolol adds vasodilation.
✅ AASK Trial (African American Study of Kidney Disease and Hypertension):
Compared ramipril, metoprolol, amlodipine in CKD patients.
Metoprolol reduced ESRD and death more effectively than amlodipine.
Confirms β-blockers as valuable add-ons to RAAS blockade, especially with CVD.
👉 Takeaway:
RAAS blockade remains first-line in CKD hypertension.
Among β-blockers, Carvedilol (vasodilatory, cardiorenal protection) and Metoprolol (AASK outcome benefit, lipophilic) are the most preferred in CKD patients, including those on dialysis.
