Athlete's heart syndrome is enlargement of the heart muscle that develops in people who exercise
regularly and vigorously. The changes in the heart may be mistaken for hypertrophic cardiomyopathy, which can cause life-threatening heart rhythms and
sudden death. But athlete's heart syndrome is harmless.
When an athlete stops
training, the heart returns to a normal size. In people with hypertrophic
cardiomyopathy, the heart remains enlarged.
