What causes a feeling of chest tightness or blockage when lying down, and what should I do about it?

Feeling chest tightness or discomfort while lying down may be caused by factors such as high mental stress, myocarditis, or pericarditis. Symptoms can be improved with medication. Detailed explanations are as follows:

1. High Mental Stress

Frequent anxiety or depression may cause the body to release hormones and neurotransmitters such as adrenaline and noradrenaline. These substances can stimulate the heart and blood vessels, leading to increased heart rate and elevated blood pressure. It is important to relax and maintain a positive mood. Engaging in social activities and communicating more with family members can be helpful.

2. Myocarditis

Myocarditis is a condition characterized by inflammation and damage to the heart muscle, which may lead to reduced cardiac function and myocardial ischemia, causing symptoms such as palpitations and chest tightness. Patients can take medications such as oseltamivir phosphate granules or prednisone tablets under medical supervision.

3. Pericarditis

Pericarditis refers to inflammation and damage of the pericardium, which may result in pericardial effusion, pericardial compression, and myocardial ischemia, causing symptoms like palpitations and rapid heartbeat. Patients can be treated with medications such as enteric-coated aspirin tablets or dexamethasone sodium phosphate injection under a doctor's guidance.

Besides the above causes, similar symptoms may also result from congenital heart disease, pulmonary embolism, myocardial infarction, and other conditions. It is important to maintain healthy lifestyle habits. If any physical discomfort occurs, prompt medical evaluation at a hospital is recommended.
