Dilated cardiomyopathy can be inherited by both daughters and sons. Dilated cardiomyopathy is a heterogeneous cardiomyopathy, which is characterized by left ventricular or biventricular enlargement accompanied by systolic dysfunction, and is inherited in autosomal dominant, autosomal recessive, mitochondrial, and X-linked modes of inheritance, with both daughters and sons at risk. However, although more and more dilated cardiomyopathies have been determined to be genetically related through the development of genetic testing in recent years, this does not mean that all dilated cardiomyopathies are genetically caused. The disease is still in the research stage, and the cause of the disease in the majority of patients is not yet clear, and in some patients, it is related to infections, non-infectious inflammation, endocrine and metabolic disorders, and toxicity, among other factors. In order to reduce myocardial damage and prevent sudden death, once patients are diagnosed with dilated cardiomyopathy, they should go to the hospital in time and actively cooperate with professional doctors for treatment.
