Why lie down? Heart's sick.

Lying heart discomfort may be caused by physiological factors, myocarditis, heart failure and other factors. The specific analysis is as follows:

1. Physiological factors

If the patient drinks strong tea before going to bed, strenuous exercise, mental tension, etc., at this time, myocardial contraction will increase rapidly, leading to increased blood pressure, increasing the burden on the heart, which will cause lying heart discomfort.

2. Myocarditis

Myocarditis will cause myocardial congestion, edema, resulting in increased pericardial friction. When lying down, cardiac contraction and relaxation are damaged, which will affect myocardial blood pumping, resulting in heart discomfort.

3. Heart failure

After heart failure occurs, myocardial function is weakened, resulting in abnormal cardiac contraction. When lying down, the amount of return blood is reduced, causing cardiac ischemia and hypoxia.
