A case of Dressler’s syndrome successfully treated with colchicine and acetaminophen

Abstract The incidence of Dressler’s syndrome after myocardial infarction (MI) has decreased in the reperfusion therapy era. Although guidelines recommend high-dose aspirin for treatment based on evidence from the pre-percutaneous coronary intervention (pre-PCI) era, bleeding and thrombotic concerns occurred upon aspirin administration after coronary stenting. A 69-year-old man with recent MI was admitted to our hospital. The patient presented with chest pain 1 week before admission. Electrocardiography revealed newly detected atrial fibrillation with no ST segment change. Urgent coronary angiography demonstrated a left circumflex artery occlusion. He underwent PCI, and a sirolimus-eluting stent was deployed. Aspirin, prasugrel, and apixaban were administered. However, hospital discharge was delayed because he developed heart failure during hospitalization. Twenty-three days after admission, he developed a fever of >39 °C. Electrocardiography showed anterior ST segment elevation, and echocardiography revealed a 6-mm pericardial effusion. We diagnosed the patient with Dressler’s syndrome, and colchicine 0.5 mg/day + acetaminophen 2000 mg/day were administered. His condition clinically improved after treatment and he was discharged 32 days after admission. There was hesitation about administration of high-dose aspirin in a patient who has undergone recent coronary stenting. Combination therapy of colchicine and acetaminophen could be a treatment option for Dressler’s syndrome.
