What age group is most commonly affected by hypertrophic cardiomyopathy?

Hypertrophic cardiomyopathy (HCM) is most commonly diagnosed in younger populations, particularly in adolescents and young adults. This condition is characterized by the thickening of the heart muscle, which can lead to various complications, including arrhythmias and heart failure.

While it may seem that middle-aged adults could be commonly affected, as HCM is often identified in this age group due to increased surveillance and symptoms arising in adulthood, the initial onset commonly occurs in adolescence or young adulthood. Many individuals may have a genetic predisposition to this condition, which often becomes evident during physical exertion or athletic activities typical of this age group.

In conclusion, the highest prevalence of HCM is seen in younger populations, particularly in adolescents and young adults, reflecting the genetic nature of the disease and its presentation during the physically active years of life.
