Cardiac pathological conditions in young soldiers: case series.

We briefly review the disease processes for four young healthy soldiers who presented to our emergency department with serious cardiac pathological conditions. We present two unusual cases of myocardial infarction, a coronary artery aneurysm, and a case of smallpox vaccine-induced myocarditis/pericarditis. Our intent is to encourage others in military medicine to maintain a high index of suspicion for cardiac conditions even in a relatively young healthy population.
