RESUMO
It is generally accepted that vigorous exercise may trigger cardiovascular accidents if underlying cardiovascular disease is present. Coronary artery disease is the most frequent cause of sudden cardiac arrest, especially in older individuals (> or = 35 years of age). We describe two patients who presented with cardiac arrest followed by loss of consciousness. Both had been participating in a marathon race. After acute myocardial infarction was diagnosed by electrocardiography and laboratory findings, urgent percutaneous coronary intervention was performed on both patients.

Coronary artery involvement leading to acute coronary syndrome is a rare complication of essential thrombocythemia. A 43-year-old woman with essential thrombocythemia complained of severe acute chest pain. She had undergone percutaneous coronary intervention (PCI) with a drug-eluting stent (DES), due to unstable angina, 3 and 2 years earlier. Emergency coronary angiography revealed total occlusion of the DES with thrombus. Twenty minutes after successful primary PCI with a DES, an acute stent thrombosis developed. She was subsequently treated with coronary artery bypass graft surgery.
