Sudden cardiac death in young athletes is rare but can be caused by coronary anomalies. This case highlights an anomalous left coronary artery as a potential cause of sudden cardiac death during strenuous exercise.
Area of Science:
- Cardiology
- Sports Medicine
- Pathology
Background:
- Sudden cardiac death (SCD) in young athletes is a critical concern, with coronary anomalies being a significant cause.
- Coronary artery anomalies are the second leading cause of SCD in athletes, following hypertrophic cardiomyopathy.
Observation:
- A 35-year-old male runner collapsed during a half marathon, experiencing pulseless electrical activity (PEA) despite resuscitation efforts.
- The autopsy revealed an anomalous left coronary artery (ALCA) as the underlying cause of the fatal event.
Findings:
- The autopsy confirmed ALCA, a condition where the coronary artery originates abnormally.
- This anatomical variation can lead to myocardial ischemia during periods of intense physical stress.
Implications:
- This case underscores the importance of screening for coronary artery anomalies in athletes to prevent SCD.
- Awareness of ALCA and its potential to cause exercise-induced ischemia is crucial for sports cardiology and emergency response.
- Further research into pre-participation screening protocols for identifying at-risk athletes is warranted.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
