The probability of inheritance of dilated cardiomyopathy is approximately 25-50% and is due to a genetic mutation or family genetic background, an autosomal dominant inheritance. In some patients, it may be due to mitochondrial inheritance, or X-chromosome chain recessive inheritance, which is a less common form of inheritance. In addition to family genetics that can cause dilated cardiomyopathy in patients, for example, patients can also develop dilated cardiomyopathy due to the use of chemotherapy drugs, and also in people who have been drinking alcohol for a long time. There are also patients who may develop perinatal cardiomyopathy during the perinatal period, which is also a specific type of dilated cardiomyopathy.
