During a pre-participation exam, a 22-year-old athlete reports mild fatigue, systemic body aches, dyspnea, pitting edema, and palpitations. What condition should the athletic trainer suspect?

During a pre-participation exam, a 22-year-old athlete reports mild fatigue, systemic body aches, dyspnea, pitting edema, and palpitations. What condition should the athletic trainer suspect?

• A. Mononucleosis
• B. Myocarditis
• C. Sickle cell anemia
• D. Pulmonary embolus

Answer: (B)

Inflammation of the heart muscle can impair the heart’s ability to pump and cause electrical instability. When the myocardium is inflamed, exercise can reveal reduced cardiac output and a tendency toward abnormal heart rhythms, which explains why an athlete might feel more fatigued during activity, experience shortness of breath, and notice palpitations. The combination of systemic symptoms with signs of cardiac involvement—mild fatigue, body aches, difficulty breathing, fluid buildup leading to pitting edema, and palpitations—points toward myocarditis rather than a simple infectious illness. The edema indicates fluid retention from the heart not pumping effectively, which is a hallmark of cardiac involvement. In the athletic population, myocarditis is particularly concerning because ongoing strenuous activity can precipitate dangerous arrhythmias or sudden cardiac death, so this finding should trigger immediate medical evaluation and temporary cessation from sports. While mononucleosis can present with fatigue and aches, edema and significant dyspnea lean toward a cardiac process rather than a typical mono presentation. Sickle cell anemia could cause fatigue but edema and dyspnea in this context are more suggestive of cardiac involvement. A pulmonary embolus could cause dyspnea and tachycardia but edema is not the defining feature here, and the overall symptom cluster fits myocarditis more closely. In short, the symptoms signal inflammation of the heart muscle affecting both pumping and rhythm, making myocarditis the most appropriate concern in this scenario.
