Management of Hypertension in Patients with Acute Kidney Injury

Medication Adjustments

The American Heart Association recommends optimizing beta-blocker therapy by considering increasing metoprolol dose if tolerated, as the current 60 mg daily may not be at maximum effective dose 1
The American College of Cardiology suggests adding a thiazide-like diuretic such as chlorthalidone 12.5-25 mg daily or indapamide 1.25-2.5 mg daily to manage hypertension in patients with acute kidney injury 1, 2
Thiazide-like diuretics are preferred over thiazide diuretics due to longer duration of action and potentially better cardiovascular outcomes, according to the American Heart Association 1
The American College of Cardiology recommends starting at lower doses to minimize electrolyte disturbances and monitoring renal function closely when adding a thiazide-like diuretic 2
Consider adding spironolactone 25 mg daily if blood pressure remains uncontrolled and renal function permits (eGFR >45 ml/min), as suggested by the American Heart Association 1, 2

The American Heart Association recommends targeting blood pressure should be <130/80 mmHg, and considering ambulatory or home blood pressure monitoring to better assess control throughout the day 1, 3
Wide fluctuations in blood pressure suggest poor control that needs to be addressed, according to the American College of Cardiology 3

The American College of Cardiology suggests rechecking blood pressure within 2-4 weeks after medication adjustment, and aiming to achieve target blood pressure within 3 months of treatment initiation 1, 2
Consider nephrology consultation if renal function worsens or blood pressure remains uncontrolled despite multiple medication adjustments, as recommended by the American Heart Association 2
