Mother’s dilated heart disease is passed on to her son, and granddaughters are in the high prevalence group, but they do not necessarily get dilated heart disease.
Dilated cardiomyopathy is a pathologic manifestation of left ventricular or biventricular enlargement with systolic dysfunction. The etiology is varied, with about half of the cases having an unknown cause. It runs in families in some patients. However, familial inheritance is only a high prevalence, and the probability of the disease is not 100%.
The onset of the disease is relatively insidious, and it may be asymptomatic in the early stages, with typical clinical manifestations of decreased activity tolerance and dyspnea during activity. In the late stage of the disease, there may be paroxysmal dyspnea and sedentary respiration at night, and left heart insufficiency, as well as right heart insufficiency such as a gradual decrease in appetite, lower limb edema and abdominal distension. Severe cases may be combined with arrhythmia and persistent hypotension.
It is recommended that high-risk individuals be closely monitored, and it is recommended that cardiac ultrasound and other tests be performed from infancy to early detection of possible heart disease.
