In your life, you may have experienced a sudden pain in your chest. Some people don't think so, and feel that patience will pass; Some people feel that there is something wrong with their hearts in panic. In fact, most chest pains cannot be explained by heart disease, but some chest pains can be fatal. Life Times interviewed authoritative experts and told you how to distinguish different symptoms according to the time of chest pain. Interviewed expert Chief Physician, Department of Cardiology, First Affiliated Hospital of Harbin Medical University; Chief Physician, Department of Cardiology, Affiliated Hospital of Tang Southeast University; Five chest pain times reflect different diseases. Chest pain is a common discomfort symptom in life, and many diseases are mainly manifested in it. According to rough statistics, there are more than 30 kinds, many of which are related to cardiovascular diseases. If you don't see a doctor in time, it may have serious consequences. Tang reminded that if chest pain lasts for 20 minutes, myocardial infarction should be highly suspected. Generally speaking, be alert for more than 5 minutes. According to the characteristics and duration of different attacks, chest pain can provide important clues for finding different causes. 1, usually a few minutes, not more than ten minutes. Coronary heart disease is the chief culprit of chest pain and chest tightness, which can be divided into stable angina pectoris, unstable angina pectoris and acute myocardial infarction according to its severity and attack time. Stable angina pectoris often manifests as dull pain in the chest, located in the left precordial area or back, sometimes radiating to the left arm and even toothache. It usually happens in the case of physical activity, emotional excitement or satiety, and rest and taking nitroglycerin can obviously alleviate it. Unstable angina can occur at rest and last a little longer than stable angina. After rest and taking nitroglycerin, it can be relieved, but the speed is slow. 2. Acute myocardial infarction, lasting more than 1 hour, is the rapid evolution of coronary heart disease. Under pressure, coronary plaque ruptures to form acute thrombus, which completely blocks blood vessels. At this time, the patient's chest pain is severe and persistent, and some can even last for three or four hours. Taking nitroglycerin is useless, accompanied by sweating or fever. It must be reminded that although the pain caused by myocardial infarction can last for several hours, as long as you find chest pain for more than 20 minutes, you should go to the hospital immediately for emergency treatment. 3. Pulmonary embolism, which can be long or short, is an emergency in which thrombus blocks the pulmonary artery and its branches, resulting in blood flow disorder. Most of them are caused by deep venous thrombosis of lower limbs and circulation to pulmonary artery. At the onset, the patient will have one or more manifestations such as dyspnea, syncope, chest pain, hemoptysis, and feeling of dying. The feeling of chest pain is similar to angina pectoris, which is characterized by dull pain in the chest, but it has no obvious improvement after taking nitroglycerin or resting. If chest pain is accompanied by dyspnea or even syncope, you should go to the hospital immediately. 4. Persistent and unrelenting chest pain refers to the formation of a false cavity between the aortic blood vessel walls, where blood gathers, resulting in thinning of the blood vessel walls. When the patient's blood pressure rises sharply, it can rupture the blood vessel wall, cause massive bleeding, form hemorrhagic shock and endanger life. The onset is often manifested as severe pain in the chest and back, which can not be relieved by rest or drug treatment. If the patient has a long history of hypertension, he should be alert to severe chest pain. 5. A short-lasting pneumothorax is a pleural rupture caused by trauma, tumor or medical operation, and gas enters the chest cavity. Most patients occur during normal activities or quiet rest, and some occur when carrying heavy objects, holding their breath or strenuous physical activity. The patient suddenly felt chest pain on one side, similar to acupuncture or knife cutting, and then quickly developed chest tightness, dyspnea and cough. The condition has not been significantly relieved by taking medicine, so you should go to the hospital for treatment. Some chest pains are not caused by heart disease. There are many causes of chest pain, including diseases of chest wall, lungs, pleura and esophagus, as well as cervical spondylosis, heart disease, stomach disease and nervous system diseases. After interviewing a number of senior cardiologists, the American magazine Health pointed out that although chest pain caused by the following seven conditions is not caused by heart disease, it should be handled with caution. The typical symptom of heartburn gastroesophageal reflux disease is gastric acid reflux to esophagus. Due to the strong acidity of gastric acid, the pH value is about 2, which leads to a burning sensation behind the sternum, which makes people have symptoms similar to chest pain. Most people will occasionally have gastric acid reflux, which does not need special attention, but if it occurs more than twice a week, it is likely to be a sign of gastroesophageal reflux disease. Long-term untreated, asthma, chest tightness and other discomforts will come to you, and the risk of patients suffering from a rare esophageal cancer will also increase. Muscle strain People who have just started fitness should pay special attention. If you don't lift weights for a long time, your chest muscles will be easily strained. Dr Christine Jellis, from Cleveland Clinic in the United States, said that it is difficult for ordinary people to distinguish between chest pain caused by a heart attack and chest muscle strain, so it is important to remember one thing: if the pain is aggravated by pressing the chest, it is probably a muscle injury, not a heart problem. A study published in American Family Physician magazine showed that 13%~36% patients who came to the emergency department for acute chest pain were finally diagnosed as costal chondritis. Virus infection and chest injury may be the reasons. Patients usually feel pressure on the chest wall, similar to muscle strain. If you are diagnosed with costal chondritis, the pain will disappear within a few days or weeks, and over-the-counter painkillers can relieve the symptoms. Herpes Zoster Salman Ai Rui, a cardiologist at McGovern School of Medicine at the University of Texas, said that the initial symptoms of herpes zoster include itchy skin and burning sensation. If the infection site is above the chest, it is easy to be mistaken for a heart attack. But in fact, after a few days, rashes and blisters will appear one after another. It should be reminded that varicella virus can remain in the body for a long time after the symptoms disappear, and even recover its activity in adults (usually people over 50 years old). Pericarditis If you got a viral infection a few days ago and woke up in the middle of the night with a stabbing pain in your chest, you probably got pericarditis. Dr. Ai Rui said that the common cause of pericarditis is respiratory infection, and other causes include lupus and rheumatoid arthritis. Pericarditis is generally harmless, but it may affect the quality of life. The doctor will diagnose the condition through CT scan and chest X-ray, and the patient can eliminate the condition simply by resting or taking over-the-counter painkillers such as ibuprofen. Other serious diseases in abdominal cavity may also lead to severe chest pain, such as acute pancreatitis. The pancreas is behind the stomach, and severe abdominal pain caused by pancreatitis can radiate to the chest, usually deep-seated pain. The chief culprit of pancreatitis is infection caused by gallstones, which is more likely to occur in female population. Patients should be hospitalized immediately and receive blood test, CT scan and abdominal ultrasound examination. Panic attack panic attack sometimes looks like a heart attack, and even has a sense of dying. In addition to chest pain, the symptoms of panic attacks include heart pounding, sweating, trembling, nausea, dizziness and so on. They sometimes happen without warning, and some major changes or excessive pressure in life may trigger them. For the above chest pain, experts suggest that you should seek medical advice as soon as possible.
