Which type of cardiomyopathy is most likely to be inherited?

The life expectancy of someone with familial cardiomyopathy can vary significantly depending on a range of factors, including the specific type of cardiomyopathy, severity of symptoms, and response to treatment. Generally, early diagnosis and proper management can lead to improved outcomes; however, individuals may have a reduced life expectancy compared to the general population if the condition is severe and left untreated.
