What is primary cardiomyopathy?

Primary cardiomyopathy is a group of heart diseases caused by abnormal structure, function or metabolism of the myocardium itself. It is a rare heart disease that affects the normal contraction and blood pumping function of the heart and leads to decreased heart function.

The occurrence of this disease is generally related to genetic and genetic mutations, which can cause abnormal structure and function of myocardial cells, resulting in cardiac enlargement, fatigue, shortness of breath, arrhythmia, syncope and other symptoms. It can usually be diagnosed by ECG, Holter ECG, chest X-ray, MRI, and cardiography.
