How does heart failure happen?

Heart failure refers to heart failure, heart failure may be caused by myocardial disease, heart overload, ventricular preload insufficiency and other reasons.

1. Myocardial disease

If the patient has metabolic diseases, connective tissue diseases, immune response and other diseases, resulting in myocardial cell damage, resulting in myocardial disease, resulting in heart failure.

2. Heart overload

If the patient's heart overload, so that the heart, myocardium change their own structure, to meet the heart pumping demand, but due to the heart, myocardial compensation capacity is limited, so that the structure, function loss of compensation capacity, heart failure.

3. Ventricular preload insufficiency

If the patient has mitral stenosis, cardiac tamponade, restrictive pericardial disease and other diseases, resulting in ventricular preload insufficiency, but also easy to cause heart failure.
