NSAIDs in Heart Failure: Recommendations and Precautions
NSAIDs should be avoided in patients with heart failure unless absolutely essential, as they increase the risk of heart failure exacerbation, hospitalization, and mortality. 1
Risks of NSAIDs in Heart Failure
- NSAIDs can cause or worsen heart failure through several mechanisms, with effects that are typically reversible when the drug is withdrawn 2
- NSAIDs may attenuate the effect of diuretics, leading to fluid retention and edema 1
- NSAIDs can blunt the cardiovascular effects of several therapeutic agents used to treat heart failure, including diuretics, ACE inhibitors, and angiotensin receptor blockers (ARBs) 3
- NSAID use in patients with heart failure is associated with an increased risk of myocardial infarction, hospitalization for heart failure, and death 3
- Both traditional NSAIDs and COX-2 inhibitors are associated with an increased risk of heart failure leading to hospitalization, even in patients without a prior history of heart failure 4
Specific Contraindications and Cautions
- NSAIDs are contraindicated in the setting of coronary artery bypass graft (CABG) surgery 3
- Avoid NSAIDs in patients with a recent myocardial infarction unless benefits clearly outweigh risks 3
- NSAIDs can lead to onset of new hypertension or worsening of preexisting hypertension 3
- Patients taking thiazides or loop diuretics may have impaired response to these therapies when taking NSAIDs 3
- The risk of heart failure exacerbation is particularly high in elderly patients and those with pre-existing cardiovascular disease 5
Alternative Pain Management Approaches
- For chronic non-cancer pain in heart failure patients, non-pharmacologic and non-opioid pharmacologic therapy are preferred 1
- Paracetamol (acetaminophen) appears to be safe in heart failure patients 1
- For gout pain in heart failure patients, colchicine is recommended instead of NSAIDs 1
- If pain persists despite non-pharmacological and non-opioid pharmacologic therapy, opioids may be considered at the lowest effective dose for the shortest duration 1
- In patients with severely impaired renal function, opioids with a safer metabolic profile (methadone, buprenorphine, or fentanyl) are preferred 1
Monitoring and Management if NSAIDs Must Be Used
- If NSAIDs are absolutely essential, use the lowest effective dose for the shortest possible duration 3
- Monitor blood pressure closely during the initiation of NSAID treatment and throughout therapy 3
- Watch for signs of worsening heart failure, including increased dyspnea, edema, and weight gain 1
- Monitor renal function and electrolytes regularly, as NSAIDs can cause renal impairment, especially in patients already taking diuretics and ACE inhibitors 3
- Be vigilant for signs of fluid retention and edema, which have been observed in patients treated with NSAIDs 3
Patient Education
- Advise patients with heart failure to avoid over-the-counter NSAIDs not prescribed by a physician 1
- Educate patients about the potential risks of NSAIDs and the importance of reporting any worsening of heart failure symptoms 1
- Inform patients about alternative pain management strategies that are safer in the context of heart failure 1
Special Considerations
- The risk of adverse cardiovascular effects from NSAIDs is present from the start of treatment, suggesting there is no "safe window" for NSAID use in patients with cardiovascular disease 6
- There is a dose-related response in risk associated with NSAID therapy, supporting a causal association between NSAIDs and cardiovascular events 6
- Among all NSAIDs, ketorolac has been associated with the highest risk of heart failure 4
Remember that the burden of illness resulting from NSAID-related heart failure may exceed that resulting from gastrointestinal damage, making this an important consideration in prescribing decisions 5.
