In an 84‑year‑old male with hypertension, moderate aortic stenosis, coronary artery disease status post percutaneous coronary intervention, renal cell carcinoma post‑ablation, chronic pain, and recent squamous cell carcinoma of the mandible resection with neck dissection, repeat exploration, hematoma evacuation and tracheostomy complicated by agitation, fever, aspiration‑related hypoxic respiratory failure and new acute kidney injury, who is now on sertraline (started two weeks ago to replace clonazepam and trazodone) and low‑dose aspirin for secondary prevention, should the baby aspirin be discontinued while continuing sertraline due to increased bleeding risk?

Should Aspirin Be Discontinued in This 84-Year-Old Post-PCI Patient on Sertraline?

No—aspirin should be continued in this patient despite the concurrent use of sertraline, because the cardiovascular benefit of aspirin for secondary prevention after PCI far outweighs the modest incremental bleeding risk from the SSRI-aspirin interaction. 1, 2

Rationale for Continuing Aspirin

Strong Indication for Aspirin in This Patient

• This patient has coronary artery disease status post percutaneous coronary intervention, which is a Class I indication for continuing aspirin indefinitely for secondary prevention. 1, 2

• The ACC/AHA guidelines explicitly state that aspirin should be continued in patients with prior PCI, and if interrupted, should be restarted immediately postoperatively. 1, 2

• Discontinuation of aspirin in patients with established coronary disease increases the absolute risk of cardiovascular events by approximately 2% within 30 days. 2

The SSRI-Aspirin Bleeding Risk Is Real But Manageable

• The FDA label for sertraline confirms that SSRIs may increase bleeding risk when combined with aspirin, NSAIDs, or anticoagulants, but this is a cautionary warning—not an absolute contraindication. 3

• The sertraline label states: "Patients should be cautioned about the concomitant use of sertraline and NSAIDs, aspirin, warfarin, or other drugs that affect coagulation since combined use of psychotropic drugs that interfere with serotonin reuptake and these agents has been associated with an increased risk of bleeding." 3

• However, this bleeding risk is predominantly gastrointestinal and can be mitigated with proton pump inhibitor (PPI) prophylaxis. 4

Risk-Benefit Analysis in This Specific Patient

High Thrombotic Risk Factors Present

• Age 84 years, hypertension, moderate aortic stenosis, and coronary artery disease with prior PCI all confer high ischemic/thrombotic risk. 1, 5

• The recent surgical procedures (mandible resection, neck dissection, hematoma evacuation) and acute kidney injury further elevate cardiovascular risk during this vulnerable period. 1

Bleeding Risk Mitigation Strategies

• Use low-dose aspirin (75-100 mg daily) rather than higher doses, as doses above 100 mg increase bleeding without improving cardiovascular outcomes. 2, 6

• Add a proton pump inhibitor for gastroprotection, which is strongly recommended for patients at increased GI bleeding risk on combined antiplatelet and SSRI therapy. 6, 4

• Monitor for clinical bleeding signs (ecchymoses, hematomas, epistaxis, GI bleeding) but do not discontinue aspirin preemptively. 3

What NOT to Do

• Do not discontinue aspirin in a patient with established CAD and prior PCI based solely on SSRI initiation—the thrombotic risk of aspirin withdrawal far exceeds the bleeding risk of the combination. 1, 2

• Do not use aspirin doses above 100 mg in this setting, as higher doses increase bleeding without added cardiovascular benefit. 2, 6

• Do not add NSAIDs to this regimen, as the combination of SSRI + aspirin + NSAID substantially increases bleeding risk. 3

Alternative Consideration: Could Sertraline Be Stopped Instead?

• If the clinical team is genuinely concerned about bleeding risk, the more appropriate question is whether sertraline is essential in this acutely ill 84-year-old patient who is only two weeks into therapy. 3

• Sertraline was started to replace benzodiazepines and improve memory, but in the context of acute kidney injury, recent major surgery, and high cardiovascular risk, the priority should be cardiovascular protection. 1, 2

• Sertraline can be safely discontinued with gradual tapering if needed, whereas aspirin discontinuation in this patient carries immediate and substantial thrombotic risk. 3

Clinical Algorithm

1. Continue aspirin 75-100 mg daily for secondary prevention after PCI. 2
2. Continue sertraline if psychiatric indication is strong, but consider deferring or tapering if bleeding concerns are paramount. 3
3. Add PPI prophylaxis (e.g., omeprazole 20 mg daily) to reduce GI bleeding risk. 6, 4
4. Monitor hemoglobin and clinical bleeding signs during hospitalization. 4
5. Avoid NSAIDs and ensure no over-the-counter antiplatelet medications are being used. 3
6. Reassess sertraline necessity once acute medical issues resolve and patient is stable. 3
