In clinical work, we often encounter many patients with chest pain. Some patients are not seriously ill after asking medical history and symptoms or examination, but he is very nervous and always feels that the doctor has belittled him and does not believe it, and he has to go to other doctors or go to other hospitals again, and as a result, he has done a whole bunch of examination or even prescribed a whole bunch of drugs, and nothing has improved after eating; while another part of patients, after asking medical history and symptoms, the doctor The patient feels that the disease is serious, very dangerous or even potentially life-threatening, but the patient feels that the doctor is intentionally scaring him, or do not believe that the result will be a big problem. The reason for this is that some people lack a minimum of medical common sense. What exactly are the chest pains that need to be taken seriously? Here I will introduce you to several common features of chest pain: 1, aortic coarctation: more than 80% of people suffering from this disease are suffering from hypertension, and usually poor blood pressure control, or even never take antihypertensive drugs, so that blood pressure has been at a high level. Most patients have chest pain that occurs during strenuous activity, and the chest pain begins to be particularly intense and can be accompanied by profuse sweating. If the site of the entrapment occurs close to the heart, the artery ruptures soon after the occurrence of severe chest pain causing the patient to die immediately after the chest pain; if the site of the entrapment occurs far from the heart, the severe chest pain turns into chest tightness followed by symptoms such as abdominal pain and bloating, indicating that the entrapment continues to extend downward and is very dangerous. It is recommended that patients with the above conditions should go to the hospital as early as possible. 2. Coronary artery disease: The following risk factors are often present: hypertension, hyperlipidemia, diabetes, smoking, obesity, family history of coronary artery disease, age above 35 years for women and above 30 years for men. Having more than 3 of these risk factors in addition to age makes you susceptible to coronary heart disease. Chest pain can be divided into angina pectoris and myocardial infarction. Because of its episodic nature, chest pain is easily ignored by patients. Most of them are posterior sternal pain, dissipating to the left shoulder and arm, usually occurring at the time of activity or in the morning when cold air is encountered. Angina pectoris lasts for several minutes each time and is relieved after rest or elimination of triggers, and there is no discomfort after chest pain is relieved. If the chest pain is severe and lasts for more than 30 minutes, accompanied by heavy sweating, chest tightness or even a feeling of suffocation, it means that it has developed into an acute myocardial infarction. Even if the chest pain is relieved and there is no discomfort anymore, you should go to the hospital as soon as possible and at least have an electrocardiogram to determine whether it is an acute myocardial infarction. Clinically, we encounter many patients with acute myocardial infarction who should have been hospitalized immediately, but the patient feels that you are fooling him, thus delaying treatment. There are also some patients who feel like eating chili noodles in their throat during an attack during activity or like someone pinching their neck, which are all symptoms of angina pectoris and should be seen in hospital in time. 3.Pulmonary embolism: Most patients have the following causes: venous thrombosis of lower limbs, long-term bed rest, chronic cardiopulmonary disease, post-surgery, trauma (including soft tissue contusion), fracture, malignant tumor, obesity, pregnancy and oral contraceptives, etc. A few have no clear cause. The symptoms of chest pain are not obvious, some patients have chest pain when they inhale deeply or cough, some patients have chest pain when they move, most patients have chest tightness, shortness of breath, dry cough and other symptoms when they move. Some patients may also experience hemoptysis or even fainting. Most patients will have decreased blood pressure, and increased respiration and heart rate. Since acute pulmonary artery trunk embolism will lead to death and small pulmonary artery embolism will turn into chronic pulmonary infarction, therefore, if the patient has the above-mentioned etiology, he or she must go to the hospital after the appearance of chest pain, so as not to miss the time of treatment. 4, spontaneous pneumothorax: Mostly seen in thin and tall healthy young people, patients with chronic lung diseases, mostly occurs after holding heavy objects, breath-holding, strenuous activities or coughing, suddenly feeling chest tightness and shortness of breath, which is persistent; one side of chest pain, not severe, mostly occurs during activities or coughing, which can be tolerated. There may be a cough, but little sputum. The diagnosis can be confirmed by taking a chest X-ray at the hospital. If a thin and tall young person develops the above situation, he should go to the hospital in time to avoid delaying the disease. 5.Lung cancer: Patients may have chest pain, which is aggravated when breathing and coughing. In addition to chest pain, early patients may have irritating cough, chest tightness and shortness of breath, or even hemoptysis, accompanied by gradual loss of weight, weakness and loss of appetite, etc. 6, pneumonia pleurisy: with a history of upper respiratory tract infection, chest pain with coughing or deep inspiration is prominent, mostly accompanied by fever, cough, coughing sputum, and even chest tightness and shortness of breath. The above symptoms can be reduced after the application of anti-infective drugs. 7.Acute pericarditis: chest pain and fever appear at the same time, chest pain is mostly located in the precordial area or behind the sternum, and can be radiated to the neck, left shoulder, left arm, with varying severity, and in severe cases, it is constrictive or sharp pain, which is aggravated by inspiration and coughing, and sometimes appears or aggravated when changing position or swallowing. Dyspnea may occur when there is more pericardial exudate, and the chest pain may be relieved at this time. In addition to chest pain, it is also accompanied by dry cough and other symptoms. 8, reflux esophagitis: chest pain is a burning pain located behind the sternum, mostly occurs when lying down or bending after a full meal, accompanied by symptoms such as acid reflux, heartburn, regurgitation, etc., and can also occur when sleeping. 9.Intercostal neuralgia: It is mostly caused by mental tension, emotional instability and poor sleep, and manifests as pins-and-needles pain in the chest or back, which is instantaneous but recurrent and lasts for several seconds or minutes, and can be relieved by itself, and the pain is localized to a point or no fixed part. The pain can be localized to one point or no fixed area. The above symptoms can disappear by eliminating the cause. 10.Non-suppurative costochondritis: the pain site mostly occurs in the 2nd-4th rib cartilage next to the sternum, the 2nd rib cartilage is the most common, unilateral or bilateral can be involved, the involved rib cartilage can be locally swollen and elevated, the pain is dull or sharp, there is obvious local tenderness, the skin is not red or swollen changes, severe cases can aggravate the chest pain due to upper limb activities or coughing and other actions, the chest pain lasts longer, up to several hours. Sometimes the pain also appears in the back corresponding to the anterior chest. The symptoms can be relieved by physical therapy or hot compresses as well as by taking blood-stasis-activating drugs. Herpes zoster: history of cold or upper respiratory tract infection, skin sensory allergy or neuralgia in the chest or lower back, pins and needles, localized skin with obvious tenderness, followed by clusters of corn-sized red papules, which rapidly turn into blisters. The pain site is usually on one side, such as chest pain rarely exceeds the sternum, and back pain rarely exceeds the spine. 12.Cardiac neurosis: The site of chest pain is often located in the apical region and the left sub-mammary region, often stabbing pain or vague pain, lasting for several seconds or hours, often accompanied by chest tightness, shortness of breath, palpitations, insomnia and other symptoms.
