How do NSAIDs affect heart failure management?

• A. They promote fluid retention, worsen hypertension, and impair renal function.
• B. They improve diuresis and lower blood pressure.
• C. They have no effect on HF.
• D. They improve renal function.

Answer: (A)

NSAIDs can worsen heart failure by disrupting kidney function and fluid balance. They block prostaglandin synthesis, which reduces the ability of the kidneys to maintain adequate blood flow, especially when perfusion is already challenged in heart failure. Prostaglandins help dilate the afferent arteriole and support glomerular filtration; without them, the kidney’s filtration rate can drop, leading to fluid and salt retention and higher blood pressure. This fluid buildup increases preload and can worsen edema and symptoms of HF, sometimes precipitating decompensation. In addition, reduced renal function makes diuretics less effective, complicating management further. For these reasons, NSAIDs are generally avoided in heart failure; if pain relief is needed, acetaminophen is preferred, and if NSAIDs must be used, they should be used at the lowest dose for the shortest time with close monitoring of renal function, weight, and blood pressure.
