Key result
An 18-year-old male athlete experienced a myocardial infarction triggered by heavy sports due to myocardial bridging causing 80% systolic luminal narrowing of the left anterior descending artery.
Case Report (n=1)
Myocardial bridging, although often considered a benign anatomical variant, can cause myocardial infarction in adolescent athletes, particularly triggered by heavy sports.
Alerts clinicians to consider myocardial bridging in young athletes with exertional MI; hypothesis-generating and leaves open need for screening or intervention trials.
Myocardial bridging is a common congenital abnormality of a coronary artery, and is usually thought to be a benign anatomical variant. Although rare, previous studies have reported that patients with myocardial bridging may suffer from myocardial ischemia, myocardial infarction (MI), arrhythmias and even sudden death. Here we report the case of an 18-year-old adolescent athlete with myocardial bridging resulting in MI. Coronary angiography revealed 80% luminal narrowing by systolic compression in the proximal and mid segments of the left anterior descending coronary artery, which returned to normal during diastole. We considered that heavy sports might be a potential trigger for his MI attack. Therefore, special attention should be paid to this kind of athlete, especially if adolescent.

Zhu et al. (2011) conducted a case report in Myocardial infarction caused by myocardial bridging (n=1). Myocardial bridging and heavy sports was evaluated on Myocardial infarction. An 18-year-old male athlete experienced a myocardial infarction triggered by heavy sports due to myocardial bridging causing 80% systolic luminal narrowing of the left anterior descending artery.
