What causes chest tightness and discomfort at night during sleep?

Generally, chest tightness and discomfort during sleep at night can be caused by poor air circulation, bronchitis, pneumonia, myocarditis, or coronary atherosclerotic heart disease. If physical discomfort occurs, it is recommended to seek medical attention promptly. Specific analyses are as follows:

1. Poor air circulation: If one sleeps in an environment with closed doors and windows where air does not circulate well, the indoor oxygen concentration may gradually decrease, potentially leading to symptoms such as chest tightness, difficulty breathing, and palpitations. This is considered a normal physiological phenomenon and can be improved by opening windows for ventilation or going outdoors to breathe fresh air.

2. Bronchitis: Bronchitis is an inflammation of the mucous membranes of the trachea and bronchi and surrounding tissues caused by various factors. In patients with this condition, repeated inflammatory stimulation may cause congestion, swelling, and increased secretions in the bronchi, leading to bronchial blockage and symptoms such as chest tightness, labored breathing, and coughing. Patients may take medications such as azithromycin tablets, cefaclor tablets, or cefadroxil capsules as directed by a physician.

3. Pneumonia: Pneumonia is an inflammatory condition affecting the airways, alveoli, and lung interstitium. It is contagious and usually caused by infections from viruses, fungi, or parasites, accompanied by symptoms such as cough, sputum production, fever, and difficulty breathing. Patients with pneumonia may also experience chest tightness at night. Under medical guidance, patients may use medications such as acyclovir tablets, amoxicillin capsules, or roxithromycin tablets to alleviate symptoms.

4. Myocarditis: Myocarditis is an inflammatory disease affecting myocardial cells. During onset, repeated inflammatory stimulation causes damage to myocardial cells, resulting in impaired cardiac function and symptoms such as chest tightness, shortness of breath, and palpitations. Patients may follow medical advice to use medications such as furosemide tablets, isosorbide mononitrate sustained-release tablets, or compound captopril tablets for treatment.

5. Coronary Atherosclerotic Heart Disease: If a patient has lesions in the coronary arteries, such as thrombosis or plaques, the arterial wall may thicken, causing narrowing or blockage of the arteries and resulting in myocardial hypoxia, which may lead to chest tightness during nighttime sleep. This is caused by coronary atherosclerotic heart disease. Patients may take medications such as simvastatin dispersible tablets, atorvastatin calcium tablets, or isosorbide dinitrate tablets under medical supervision.

In daily life, it is recommended to consume foods rich in protein, multiple vitamins, minerals, and other nutrients, such as eggs, lean meat, tomatoes, apples, etc., to supplement the body's energy needs and maintain overall health.
