Chest pain is a common symptom with various reasons. Several common symptoms of chest pain are described as follows: 1. Cardiovascular disease 1, coronary heart disease, angina pectoris, due to hypertension, hyperlipidemia, diabetes, smoking, inflammation, mental stress and other reasons, can cause coronary atherosclerosis that supplies blood to the heart itself, and even narrow the coronary lumen, unbalance the supply and demand of myocardial oxygen, and produce metabolites such as lactic acid through anaerobic metabolism. The site of pain is generally located behind the sternum, in the precordial area or in the cardiac fossa. The nature of pain is tenderness, dull pain, dull pain, swelling pain and so on. The degree of pain varies. The light person only feels a little pain, and the heavy person can't stand it. The radiation sites are the back, the inner side of the left upper limb, the neck and teeth. , lasting 1-30 minutes. The inducement is fatigue, full meal and exercise. Nitrates such as nitroglycerin can be quickly relieved after rest or oral administration (sublingual), and some patients have poor effect with nitroglycerin. At the time of attack, some patients' ST segment decreased, some patients' ST segment increased, and a few patients' ECG was normal, so exercise treadmill test or coronary angiography was needed for further diagnosis. Initial fatigue, progressive fatigue and variant angina pectoris are collectively referred to as unstable angina pectoris or pre-infarction state. Without proper rest and effective treatment, the condition is very easy to develop or lead to acute myocardial infarction. Over the years, major hospitals have opened green channels for some patients. Once the above three kinds of angina pectoris are diagnosed or highly suspected, they are immediately sent to the ward for treatment. Traditional Chinese medicine calls this disease chest arthralgia, which has been mentioned as early as Neijing, such as "heart disease, chest pain, hypochondriac pain, shoulder and back pain, and sore arms". Pain in the heart and mouth is called epigastric pain. In ancient Chinese medicine, the theory of simultaneous treatment of heart and stomach was limited by the underdeveloped technology at that time, and it was impossible to completely distinguish two diseases. Modern patients also confuse these two diseases. This will often delay the illness. Cardiovascular Department of our hospital has studied this disease for more than 30 years and accumulated rich experience. We believe that the syndrome differentiation of this disease is based on guilty conscience, that is, guilty conscience, deficiency of heart yin and deficiency of heart yang. And blood stasis and phlegm-dampness blocking collaterals. At present, the academic circle of traditional Chinese medicine has gradually formed a kind of knowledge that deficiency of heart-qi and blood stasis syndrome are the most common, so supplementing qi and promoting blood circulation is the most commonly used treatment. Traditional Chinese medicine is not only effective in treating angina pectoris of coronary heart disease, but also effective in treating angina pectoris after coronary stent or coronary artery bypass grafting in recent years. 2. Most patients with acute myocardial infarction develop to a serious stage due to coronary atherosclerosis. Coronary artery stenosis is very obvious, atherosclerotic plaque is unstable, rupture occurs, thrombosis is formed, and a branch of a blood vessel is blocked to cause acute myocardial infarction, which is an urgent and critical disease. The symptoms of myocardial infarction are similar to angina pectoris, but the pain is severe and lasts for more than half an hour. Nitroglycerin is not effective. Some patients sweat when they are in pain, and some are accompanied by nausea and vomiting. Some patients often mistakenly think that they have stomachache, so they are not treated in time, which delays their illness. The mortality rate was 9- 10%. Electrocardiogram showed that ST segment elevation occurred in the early stage after onset, and ST segment decreased in some patients after 6 hours, while ECG of a few patients did not change in the early stage. In addition, myocardial enzymes may increase. Through the treatment of integrated traditional Chinese and western medicine, the critical complications of acute myocardial infarction such as cardiogenic shock, heart failure and arrhythmia are greatly reduced. The anti-myocardial infarction mixture developed by the Cardiovascular Department of our hospital was later improved into Yiqi Huoxue injection, which was used to treat acute myocardial infarction and won the second-class achievement award of the Ministry of Health. 3. Acute nonspecific pericarditis: Acute pericarditis is acute inflammation of pericardium and parietal layer, and the cause of nonspecific pericarditis is not very clear. Virus infection and allergic reaction after infection may be one of the reasons. Generally speaking, it is more common in young adults, with more men than women. Upper respiratory tract infection often occurs before onset, and 60% of patients have sudden onset. The most prominent symptom is the retrosternal pain in the precordial region, which is often extremely severe, such as knife cutting, root pain, stuffy cough and aggravated breathing. The pain lasts for several days, accompanied by fever, pericardial grinding and pericardial effusion. There may be ST segment elevation in the early ECG, and the disease can heal itself and can only be treated symptomatically. No special treatment. In addition, tuberculous, rheumatic, neoplastic and systemic lupus erythematosus pericarditis can all have chest pain attacks. 4. The most common cause of aortic dissection aneurysm is hypertension. Acute aortic dissection is a hematoma in which blood penetrates into the aortic wall and separates its middle layer, also known as aortic dissection aneurysm, which can cause severe chest pain, shock and its own symptoms. If the hematoma continues to expand, it can rupture the adventitia of the arterial wall, causing massive bleeding and even death. Intima rupture or adventitia perforation of acute aortic dissection aneurysm usually occurs within 24-48 hours. Subacute type can survive for several days to weeks after onset. The chronic type survived for more than 6 weeks after the onset, but the symptoms were relieved because the distal end of aortic dissection once again protruded into the intima to form double-channel active pulsation, and there was blood or fiber unhealed in the hematoma of dissection. Chest pain is the most common symptom at the beginning of the disease, and 85% patients have this symptom. The pain is severe. It's persistent tearing or pain. The site is mostly near the sternum in the chest, extending to the back, especially the area between the two shoulder blades, and reaching the head, abdomen or lower limbs along the interlayer direction. Most of them need surgery. 2. Lung disease: 1. In the absence of trauma or human factors, pneumothorax caused by sudden rupture of lung tissue and visceral pleura is 5: 1, which is more common in young people aged 20-30. It is often caused by subpleural bubble rupture, subpleural lesions or cavity rupture, and pleural adhesion and tear. Pleural emphysema can be congenital or secondary. The former is common in pneumonia, and it is found in lanky men with no obvious diseases on chest X-ray examination. Inflated air bubbles are degraded due to nutrition and circulatory disorders, and even burst when coughing or pressure in the lungs increases (such as sudden exertion, defecation or defecation). And the sudden increase of the pressure in the trachea caused by violent actions). There are three kinds of pneumothorax: closed, open and tension. The typical symptoms of pneumothorax are sudden chest pain, followed by chest tightness or dyspnea, irritating cough, tension pneumothorax with shortness of breath, suffocation, irritability, cyanosis, sweating and shock. X-ray examination can make a definite diagnosis. 2. The etiology of pulmonary embolism is a clinical and pathological syndrome caused by pulmonary circulation disorder caused by thrombus blocking pulmonary artery or its branches in vitro. Pulmonary hemorrhage or necrosis is called pulmonary infarction. Thrombosis mainly comes from deep vein thrombosis of lower limbs; 5 1-7 1% patients with lower extremity deep vein thrombosis may have pulmonary embolism. Thrombophlebitis of lower limbs, varicose veins, atrial fibrillation with heart failure and thrombosis, long-term bedridden patients and pregnant women are all risk factors. Symptoms: chest pain, shortness of breath, hemoptysis, dyspnea, cyanosis, syncope, hyperhidrosis and even sudden death. Symptoms are related to the size of embolism. It is recommended to go to the hospital for examination and treatment. Thrombolysis or related rescue is necessary. In recent years, the incidence of pulmonary embolism has increased significantly, and the misdiagnosis rate is also high, which should be vigilant. 3, pneumonia: bacterial or viral infection, fever, cough, expectoration, chest pain, chest X-ray or chest X-ray can be clearly diagnosed. 4, lung cancer: tumor invasion of chest wall can cause continuous progressive chest pain, chest X-ray or chest CT can be diagnosed. Pleural diseases: pleurisy: Tuberculous patients are very common in China. At the beginning of the disease, chest pain gets worse, cough, and take a deep breath. When there is more pleural effusion, chest pain disappears, which may be accompanied by symptoms such as fever, night sweats, emaciation and loss of appetite. Chest x-ray or chest b-ultrasound can be diagnosed. It is necessary to draw fluid in time to prevent adhesion or package, and take enough anti-tuberculosis drugs according to the doctor's advice. Cancer cells can be found in cancerous pleural effusion and treated with anticancer therapy. Chest wall diseases: 1, costal chondritis: mostly located at the junction of the third and fourth ribs and costal cartilage, showing acupuncture-like or persistent acute pain, with slight uplift and tenderness locally. The disease is non-bacterial inflammation, so it is not necessary to take antibiotics, and ibuprofen, fenbid and other antipyretic and analgesic drugs can be taken. 2, chest wall neuropathy: neuritis caused by viruses, such as herpes zoster or intercostal neuritis, or nerve root tingling caused by spinal cord or spinal cord lesions. The pain range is mostly located in the distribution area of the diseased intercostal nerve, which is characterized by stabbing pain, burning pain and even knife pain. The intercostal nerve at the lower edge of the rib may have tenderness. Herpes zoster appears in the intercostal space and can be fused into pieces. 5. Digestive system diseases: Gastroesophageal reflux disease is a symptom and tissue damage caused by the reflux of gastric and duodenal secretions (gastric acid, pepsin, bile and pancreatic juice) to the esophagus. The main manifestations are heartburn, pantothenic acid, burning sensation behind the sternum, and chest pain. Chest pain is normal in the chest and radiates to the shoulder and the inner side of the upper arm, much like angina pectoris chest pain, mainly due to the stimulation of reflux to the esophageal mucosa, causing esophageal inflammation and pain. There are many reasons for this disease, which are often induced by emotional factors and appetite factors. Repeated and long-term existence of the disease can cause squamous epithelial hyperplasia of esophageal mucosa, or metaplasia into columnar epithelium, and may also cause cancer. Traditional Chinese medicine named the disease as noisy, acid regurgitation, plum heart qi and epigastric pain. Traditional Chinese medicine has accumulated a lot of clinical experience, which can be adjusted as a whole and has a good effect. You can refer to the above, most of them need some physical examinations to make a diagnosis!
