What causes chest tightness and blockage?

Chest tightness or blockage may be caused by environmental irritants, negative emotions, bronchial asthma, coronary atherosclerotic heart disease, heart failure, and other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a professional physician. Specific analysis is as follows:

1. Environmental irritation: Prolonged exposure to enclosed environments may lead to poor air circulation, resulting in chest tightness or a blocked sensation. It is recommended that patients move to open, well-ventilated areas or turn on indoor ventilation devices to improve airflow, which can help alleviate chest discomfort.

2. Negative emotions: Excessive excitement or chronic stress may increase the secretion of catecholamines in the body, potentially affecting myocardial blood supply and causing chest tightness. It is recommended to practice deep breathing, yoga, or similar techniques to reduce stress and relieve emotional tension, thereby improving symptoms.

3. Bronchial asthma: This may be related to factors such as allergies or pathogen infection. Chronic inflammation and spasms of the airways after onset can lead to difficulty breathing and chest tightness. Patients are advised to take medications such as diprophylline tablets, doxofylline tablets, or budesonide inhalation powder according to medical instructions.

4. Coronary atherosclerotic heart disease: This condition may result from atherosclerosis of the coronary arteries leading to vessel narrowing or blockage, which can easily cause myocardial ischemia and hypoxia, resulting in chest tightness and possibly accompanied by chest pain. Patients are advised to follow medical instructions to use medications such as simvastatin dispersible tablets, atorvastatin calcium tablets, or isosorbide dinitrate tablets.

5. Heart failure: This may be associated with myocardial disorders, valvular heart disease, or other factors. After onset, cardiac pumping function may decline, leading to poor systemic circulation and causing chest tightness. Patients may also experience symptoms such as shortness of breath and fatigue. It is recommended that patients use medications such as furosemide injection, captopril sustained-release tablets, or metoprolol tartrate tablets under medical supervision to improve their condition.

In daily life, patients are advised to maintain a low-salt diet, avoid excessive fatigue, and engage in mild exercises such as yoga or walking, which may benefit recovery.
