As the time passes by, the symptoms may get worse and spread all over the organism. The heart becomes very weak, being unable to carry out most of its primary functions. The patients start experiencing the signs of heart failure. Among these features, doctors recall breathlessness like the one people with asthma face, obstacles on the way to normal communication, feeling overloaded and tired even after a good sleep, pain in the limbs, abdomen, and neck, swelling in different parts of the body, etc. Patients also complain of feeling irritated, dizzy, and fainting suddenly in the middle of the stress. Heart murmurs and discomfort follows after each physical activity, even a medium one.

The factors that lead to this disease can be classified into several categories. The American Heart Association (AHA) has surveyed many patients and conducted numerous research studies before figuring out what exactly causes cardiomyopathy. The organization found out that there are two groups of causing factors: primary and secondary. Those factors can also be extrinsic and intrinsic. The family members and professionals have to be aware of all causes.
