Chest tightness caused by organic reasons: 1. Cardiogenic chest tightness-manifested as chest tightness after fatigue, dyspnea, or paroxysmal dyspnea at night, which can be held in sleep by patients with heart disease, which can be seen in pulmonary congestion and cardiac insufficiency. When lying down, the lung congestion is aggravated, chest tightness and dyspnea appear, and it gets better after sitting up. In addition, chest tightness can also be the manifestation of myocardial ischemia in coronary heart disease.
Pulmonary chest tightness-seen in bronchial asthma, pleural effusion, pulmonary fibrosis, etc.
Chest tightness caused by functional reasons is the most common in cardiovascular dysfunction. Patients feel chest tightness, shortness of breath, subjective lack of air, poor breathing, often sigh-like breathing, and feel comfortable after breathing; It is often accompanied by palpitations, tingling in the precordial area, and nervous system symptoms such as fatigue, dizziness, confusion, panic, anxiety, sweating and insomnia. Most of the patients were young women with obvious symptoms, but no organic lesions were found in ECG, B-ultrasound and chest X-ray examination.
The difference between organic chest tightness and functional chest tightness is that organic chest tightness mostly occurs after exercise or fatigue, while functional chest tightness mostly occurs at rest; After sitting up, the organic chest tightness can be obviously improved, while the functional chest tightness often does not change because of the change of posture.
Talking can cause chest tightness and shortness of breath. If it is pathological, or chest tightness caused by organic heart disease, it shows that cardiopulmonary failure is serious, because it is generally effortless to speak without speaking loudly for a long time. If there are no symptoms of chest tightness and shortness of breath during activities, it will cause chest tightness and shortness of breath when you talk, which is not in line with chest tightness and shortness of breath after heart disease fatigue. Even if coronary heart disease has myocardial ischemia, it will not cause ischemic symptoms because of speaking. Therefore, this situation suggests that it is a functional chest tightness symptom caused by mental reasons.
The mechanism of chest distress caused by cardiovascular dysfunction is autonomic nervous dysfunction and increased sympathetic nerve tension, which causes a series of functional symptoms and manifestations of cardiovascular system.
When you have symptoms of chest tightness and shortness of breath, you can do chest X-ray, electrocardiogram and echocardiography. If no abnormalities are found in the examination, most of them are neurological symptoms, so don't worry too much. After mental conditioning, physical enhancement, or necessary rest and medication, it will gradually improve and be cured.
