What causes chest tightness and shortness of breath? Two common situations

There are two common situations of chest tightness and shortness of breath. One is functional and the other is caused by cardiac neurosis. Common functional factors include long-term lack of fresh air circulation in the living room and chest tightness when emotionally excited. They must be differentiated and diagnosed in a timely manner.

1. Causes of chest tightness and shortness of breath

Functional chest tightness

It means that if you stay in a room with closed doors and windows and poor air circulation for a long time, or encounter some unpleasant things, or even have a quarrel or dispute with others, or are in a climate with low air pressure, you will often feel chest tightness and fatigue.

Cardiac neurosis

It is a kind of systemic neurosis with various symptoms. The most common subjective symptoms are palpitations, dyspnea, precordial pain and general fatigue. There are also manifestations such as irritability, insomnia, sweating, trembling, dizziness and nightmares.

2. Prevention

1. Prevent colds and timely prevent and treat various respiratory diseases. For example, if you have repeated colds, you can regularly inject immunoglobulin or immunoglobulin G, and take some lung-nourishing Chinese medicine appropriately to enhance the body's disease resistance.

2. In warm and windy weather, go out to bask in the sun, take a walk, do some physical activities within your ability, or enhance lung function. It is best to insist on 30 minutes of breathing exercises and deep breathing exercises every day, which can promote bronchial ventilation function.

It can also enhance the elasticity and blood supply of alveoli.

3. Pay attention to hygiene, proper nutrition, quit smoking, avoid staying in dusty places, and avoid contact with smoke and toxic gases that irritate the trachea and bronchi.

3. Differential Diagnosis

Coronary ischemia, chest tightness first

Suffer from the disease in middle-aged and elderly people, with a trend of getting younger.

Most patients with acute myocardial infarction will have precursors before the onset of the disease. When they feel chest tightness, pain behind the sternum, and sometimes radiating to the left shoulder and back, they must consider whether they have angina pectoris and go to the hospital for diagnosis and treatment in time.

Myocardial involvement, accompanied by chest tightness

High-risk groups: children and young adults.

Viral myocarditis is mostly caused by cold viruses and is more common in children and young adults. The onset of the disease is often preceded by cold symptoms such as chills, fever, body aches, sore throat, cough, or vomiting and diarrhea. Patients should pay special attention if they experience chest tightness, palpitations, shortness of breath, precordial discomfort, etc. within about 2 weeks. Since viral myocarditis has an insidious onset, it is easy for people to misunderstand it as a cold that has not been completely cured and treat it incorrectly. When the myocardium is obviously affected, children often complain of precordial discomfort, chest tightness, palpitations, dizziness and fatigue. Severely ill patients may suddenly suffer from cardiogenic shock, which is manifested by irritability, pale complexion, cold and wet limbs, and peripheral cyanosis, and accidents may occur within a short period of time.
