Treatment of Pleuritis in Patients with Coronary Stents

Antiplatelet Therapy Management

• The American College of Cardiology recommends continuing aspirin 75-100 mg daily and clopidogrel 75 mg daily without interruption to prevent catastrophic stent thrombosis in patients with pleuritis and a coronary stent 2, 3
• Premature discontinuation of dual antiplatelet therapy (DAPT) is the most powerful predictor of stent thrombosis, which carries mortality rates up to 20% 3
• For drug-eluting stents, DAPT should continue for at least 6-12 months post-implantation, as recommended by the American College of Cardiology 4, 2
• For bare metal stents, minimum DAPT duration is 4 weeks, though longer is preferred, according to the European Heart Journal 3, 5

Pleural Drainage if Indicated

• Consider chest tube drainage for symptomatic relief in patients with pleural effusion and pleuritis, as suggested by Thorax 1
• Saline irrigation (250 mL three times daily) may be used if significant fluid accumulation occurs, as recommended by Thorax 1
• For complicated pleural infection, combination tissue plasminogen activator (10 mg twice daily) plus DNase (5 mg twice daily) for 3 days can be considered, though reduced TPA doses (5 mg twice daily) should be used in patients on antiplatelet therapy due to bleeding risk, as suggested by Thorax 1

Monitoring Requirements

• Close cardiovascular monitoring is essential, including monitoring for changes in anginal pattern, which could indicate stent thrombosis, as recommended by Praxis Medical Insights 6
• Continuous ECG monitoring if symptoms suggest ischemia, as suggested by Praxis Medical Insights 6

Common Pitfalls to Avoid

• Never discontinue antiplatelet therapy to reduce bleeding risk from pleural procedures, as stent thrombosis risk far exceeds bleeding risk, according to the European Heart Journal 3
• Avoid bridging with other anticoagulants, as this is poorly studied and discouraged, as stated in The Journal of Urology 7

Additional Supportive Measures

• Provide sublingual nitroglycerin with clear instructions for any chest symptoms, as recommended by Praxis Medical Insights 6
• Continue prescribed antianginal medications throughout treatment, as suggested by Praxis Medical Insights 6
• Add proton pump inhibitor for gastrointestinal protection while on DAPT, though avoid omeprazole/esomeprazole which inhibit clopidogrel metabolism, as recommended by Praxis Medical Insights 2
