A high school athlete becomes short of breath only when exercising. What is the most appropriate next step?

• A. Permanent discontinuation of all strenuous and aerobic activities
• B. Enrollment in a conditioning program to improve performance
• C. Evaluation for underlying cardiac causes of this symptom
• D. Treatment for exercise-induced asthma with a bronchodilator

Answer: (C)

Exertional shortness of breath in a young athlete should prompt a cardiac-focused evaluation before assuming a respiratory or conditioning issue. When symptoms only occur with exercise, there’s a real need to rule out serious heart conditions that can manifest as dyspnea, chest discomfort, fainting, or fatigue during activity. A careful history and physical can reveal red flags such as dizziness, fainting with exertion, chest pain, or a family history of sudden cardiac death. If these raise concern, further testing like an ECG and echocardiogram, and targeted evaluation for conditions such as cardiomyopathies or congenital heart problems, are the appropriate next steps. Taking the other paths—immediately discontinuing all strenuous activity, jumping to a conditioning program, or treating with a bronchodilator without diagnostic confirmation—can miss a dangerous cardiac issue or misattribute symptoms to asthma or deconditioning. The correct approach is to assess for cardiac causes first, ensuring safe management and appropriate activity recommendations based on the findings.
