Acute myocardial infarction (AMI) as an acute form and a catastrophic manifestation of coronary artery disease (CAD) is the major cause of morbidity and mortality worldwide. The prevalence and incidence of myocardial infarction can be influenced by demographic, biological and psychosocial factors, and it is rare in childhood and adolescent years. Contrary to the elderly, where cardiac attack is mainly caused by CAD, exercise-induced cardiac attack is relatively more prevalent in a young adult. We report here on a case of ST-segment elevation myocardial infarction (STEMI) in a young adult during vigorous physical activity and we review the relevant literatures.

Stent thrombosis (ST) is the sudden occlusion of a stented coronary artery because of thrombus formation. ST is a rare, but can result in life-threatening complications. Early stent thrombosis occurs frequently after primary percutaneous coronary intervention (PCI) for acute ST-segment elevation myocardial infarction (STEMI). Here, we report a case of a 59-year-old man with acute stent thrombosis immediately after primary PCI with drug-eluting stent for acute STEMI.
