Case Reports
Left coronary artery anomaly: an often unsuspected cause of sudden death in the military athlete.
More than 300,000 cases of sudden cardiac death (SCD) occur in the United States each year. Left coronary artery anomaly (LCAA), although rare, is second only to hypertrophic cardiomyopathy as the most common cause of SCD associated with structural cardiovascular abnormalities. This case illustrates SCD secondary to LCAA in a military athlete. ⋯ A substantial proportion of these individuals experience prodromal symptoms of exertional chest pain, syncope, and/or sudden collapse. Early recognition and intervention are key to survival. Rapid, early imaging and invasive therapeutic measures leading to surgical correction may be the difference between life and death.

The purpose of our study was to investigate possible risk factors and mechanisms for the development of pelvic stress fractures in female Navy recruits. We used a case-control retrospective study of female Navy recruits undergoing basic military training. ⋯ In addition, recruits with pelvic stress fractures reported marching in the back of their training division, were road guards, and felt that their stride was too long during training activities more often than recruits without injury. Self-reported fitness, activities before recruit training, or a history of amenorrhea was not found to be associated with the development of a pelvic stress fracture in our population.
