Description

Percutaneous transluminal coronary angioplasty (PTCA) with stent placement is widely used to achieve myocardial revascularization in patients with symptomatic ischemic heart disease and significant coronary artery stenosis. Drug-eluting stents are used in most patients undergoing percutaneous angioplasty. Stent thrombosis is an uncommon but serious complication, manifested mostly by sudden death or acute ST-elevation myocardial infarction. The authors report the case of a 68-year-old patient with acute anterior ST-elevation myocardial infarction. Five years previously, she had had a similar presentation and underwent primary angioplasty of the left anterior descending artery with implantation of a drug-eluting stent. The patient was discharged under antithrombotic therapy. She discontinued antiplatelet therapy and two days later suffered an acute anterior myocardial infarction. Primary angioplasty revealed stent thrombosis.
