NSAIDs can precipitate decompensation of chronic heart failure and are generally contraindicated in patients with reduced‑ejection‑fraction heart failure because they promote fluid retention, reduce renal perfusion, and blunt the effectiveness of guideline‑directed heart‑failure therapies.
NSAIDs are contraindicated in chronic HFrEF; they can precipitate acute decompensation.
Even short‑term, low‑dose NSAID use can impair diuretic response and raise creatinine.
Monitor weight, serum creatinine, and potassium within 1‑2 weeks of any NSAID exposure.
Prefer acetaminophen or non‑pharmacologic pain control in heart‑failure patients.
NSAIDs inhibit cyclo‑oxygenase (COX‑1 and COX‑2), decreasing prostaglandin synthesis. Prostaglandins (especially PGE₂ and PGI₂) maintain renal vasodilation and sodium excretion. Their loss leads to afferent arteriolar vasoconstriction, reduced glomerular filtration rate, sodium and water retention, and increased systemic vascular resistance. This counteracts the actions of ACE inhibitors, ARBs, beta‑blockers, and loop diuretics, worsening preload/afterload and precipitating heart‑failure decompensation.

Hot chocolate contains small amounts of tyramine and phenylethylamine, which can interact with MAOIs, potentially leading to a hypertensive crisis if consumed in large quantities, though the risk is generally low with moderate intake.
Kale, a vitamin K-rich leafy green, can interact with warfarin by potentially reducing its anticoagulant effects if intake is inconsistent or excessive.
Large amounts of lime juice may mildly interact with certain statins, similar to but less potent than grapefruit juice, by inhibiting drug metabolism and potentially increasing statin levels in the blood.
