In what demographic is dilated cardiomyopathy most commonly associated?

Dilated cardiomyopathy (DCM) is a condition characterized by the dilation and impaired contraction of the heart muscle. It can lead to heart failure and is linked to various risk factors. While it can affect different demographics, it is particularly associated with individuals who have a family history of heart disease. This hereditary predisposition suggests a genetic component to the disease, making it more prevalent in those with relatives who have experienced similar heart conditions.

Genetic mutations can play a significant role in the development of DCM, and it is not uncommon for families to exhibit patterns of heart disease, indicating that the condition can run in families. Thus, individuals with a family history are at increased risk, making this demographic the most commonly associated with dilated cardiomyopathy compared to the other options, which do not have as strong a connection to the condition.
