AbstractAcute coronary syndrome (ACS) is a rare cause of chest pain in adolescents and young adults. Kawasaki disease (KD) is an uncommon illness, but coronary artery aneurysms secondary to KD are implicated in approximately 5% of cases of ACS in young adults. Patients with KD may present with catastrophic coronary disease at a young age and thus early recognition of this disease process and lifelong follow-up is essential. Here we discuss a 19-year-old active duty male with no previously recognized medical history who presented with crushing chest pain while deployed. He was diagnosed with an ST elevation myocardial infarction and was found to have a giant aneurysm of the left main coronary artery with obstructive thrombus treated with emergent thrombectomy and balloon angioplasty. He developed cardiogenic shock requiring mechanical circulatory and ventilatory support. After a prolonged recovery and more in-depth history-taking, he was discovered to have been diagnosed with KD as a child without follow-up. Diagnosing ACS in young adults can be challenging, but a history of KD should increase suspicion for coronary disease. This case demonstrates the importance of screening after a childhood diagnosis of KD, specifically when caring for the tactical athlete. It also highlights the impact that social determinants of health can have on patient outcomes. Finally, it demonstrates the importance of communication and coordination between military and civilian medical centers across the globe driving the care of our deployed injured and ill active-duty military personnel.© The Association of Military Surgeons of the United States 2024.
