Abstract

Acute ST-segment elevation myocardial infarction (STEMI) complicated with multiple coronary artery thrombosis is a rare clinical situation
and is associated with poor prognosis. A 63-year-old male patient was admitted to the emergency department with sudden chest pain that
had started three hours ago. The patient was diagnosed with acute inferior STEMI. The emergency coronary angiography showed acute
arterial thrombosis in the left anterior descending (LAD), left circumflex (LCx), and the left first branch of the circumflex artery (obtuse
margin). Obtuse margin of the lesion was treated with a stent. We decided to infuse tirofiban (glycoprotein 2b/3a inhibition) for the
thrombosis in the LAD and CX vessels. After the tirofiban infusion, the coronary angiography showed no thrombi in the coronary arteries.
The patient was discharged without further complications.
