Summary
A marathon runner experienced ventricular fibrillation after exercise. A previously insignificant left anterior descending artery lesion was stented, resolving the life-threatening arrhythmias and chest pain during follow-up.
Area of Science:
- Cardiology
- Exercise Physiology
Background:
- Exercise-induced ventricular fibrillation is a rare but serious condition.
- Assessing coronary artery lesions in athletes requires careful consideration of functional significance.
Observation:
- A marathon runner presented with chest tightness, ST-segment depression, and ventricular fibrillation post-treadmill testing.
- Initial cardiac catheterization revealed a hemodynamically insignificant left anterior descending (LAD) artery lesion.
Findings:
- Recurrent symptoms and ventricular fibrillation during follow-up testing prompted re-evaluation.
- Coronary stenting of the LAD artery resolved the patient's exertional arrhythmias.
Implications:
- This case highlights the importance of reconsidering diagnoses when symptoms recur, even with initially insignificant findings.
- Functional assessment of coronary lesions may be crucial in athletes presenting with exercise-induced arrhythmias.
