The etiology of DCM is multifactorial. Some of the recognized causes include:
Genetic Mutations: Mutations in genes encoding proteins like dystrophin, titin, and lamin A/C can lead to DCM. Viral Infections: Myocarditis caused by viruses such as Coxsackievirus can lead to DCM. Toxins: Chronic alcohol abuse and exposure to certain drugs like doxorubicin can cause DCM. Autoimmune Disorders: Conditions like systemic lupus erythematosus can be associated with DCM.
