Heart enlargement, which belongs to the field of medicine, refers to a symptom of heart disease. In X-ray examination, enlargement of the heart is an important sign of heart disease, which includes hypertrophy of the heart wall and enlargement of the heart cavity. Dilated cardiomyopathy (DCM) is one of the causes of cardiac enlargement. Others, such as hypertensive heart disease, can cause cardiac enlargement. Cardiac enlargement is largely due to compensatory hypertrophy and hyperplasia of the myocardium. Common large common in myocarditis, heart failure, pericardial effusion, etc. The heart shadow increased to both sides and was symmetrical. Let's take a look at the following.

What is the cause of heart failure

First: viral myocarditis: in recent years, the number of viral myocardium increases, the virus has affinity for myocardium, myocardial fibrosis after myocarditis, myocardial hypertrophy, and finally the formation of cardiomyopathy. Allergic reaction: the antiviral antibody of some patients increased. It is thought that the disease is caused by the body's allergic reaction after virus infection.

Second: hypertension: about 10% of the patients have high blood pressure. But high blood pressure occurs in heart failure, heart failure control, blood pressure drop, so high blood pressure is not the main factor of the disease. Malnutrition: portal cirrhosis is more common than the general population. The incidence rate of poor living residents suggests that the disease is related to nutrition. The lack of certain essential amino acids or trace elements may be one of the factors causing morbidity.

Third: once there is heart failure, should be a long time to rest, low salt diet. In case of severe dyspnea, aggravation when lying on the back, sweating, or severe cardiac insufficiency, the patient should be asked to take a sitting or semi sitting position, call the medical emergency center for help, or take the safest, stable and fast transportation to the nearby hospital.
