From the previous sudden death of a Saudi prince to the recent sudden death of Ali’s finance director Ou Jiliang, sudden death can be a household name. Its seriousness is not much to say here, take a look at these charts first. Note that, in addition to the above three major causes, there are common secondary causes. Some people immediately say, not afraid, our family on no cardiovascular disease, so we are not afraid! In this regard, I can only regret to say: Sorry, sudden death will not favor any one person, or hold the health of the most important. So, let’s first understand three issues: 1, why excessive alcohol consumption can induce sudden death? Excessive alcohol consumption can lead to vasoconstriction, increased blood pressure, inducing cardiovascular disease, which can cause brain hemorrhage, myocardial infarction and other diseases. 2.Why is sudden death easy to happen after exercise? When the exercise is too intense, more than the limits of the body to withstand, there will be high blood pressure, rapid heart rate, myocardial hypoxia, the heart system is overwhelmed, the amount of blood oxygen demand surge, etc., in the case of blood, oxygen supply, the heart is prone to acute ischemia, resulting in myocardial infarction, cardiac rhythm disorders or acute heart failure, sudden death. 3, how does excessive fatigue induce sudden death? Excessive fatigue can cause considerable changes in the blood circulation system. If there is already a basic heart disease, the heart burden is already heavy, plus excessive fatigue, so that the heart load heavier, there can be increased myocardial tone, myocardial contraction force increased, while the myocardial demand for blood increased. If the blood supply to the myocardium is not sufficient at this time, myocardial hypoxia can lead to arrhythmias. Over 50% of cardiac arrests are preceded by warning signs from the body 1 hour to 1 month before the arrest, with chest pain being the most common in about 56% of cases, shortness of breath in 13%, and dizziness, syncope or palpitations in 4%. People ignore them because it is difficult to distinguish these warning symptoms from other diseases. For example, almost everyone has flu symptoms in the winter, but few people associate them with heart disease. Differential diagnosis, therefore, is the focus and difficulty in fighting cardiac arrest. Specifically, immediate medical attention is needed when the following 5 conditions occur: 1. Pain In comparison, the pain response is the most easily caught and perceived signal among the signs of the onset of sudden death. When you feel a sharp, tight, crushing pain in the chest and feel breathless, you should be alert. 2, potential causes In addition to pain, be alert to potential causes that may lead to sudden death. For example, whether there is a history of thrombosis-prone medical conditions. For example, a patient with a fracture who has been restricted from exercise for a period of time is prone to venous thrombosis, and once the venous thrombosis falls off, pulmonary infarction may occur. 3. Breath-holding, cyanosis, and decreased blood oxygen In addition to pain, it is important to be alert to potential causes that may lead to sudden death. For example, whether there is a history of medical conditions that predispose to thrombosis. For example, a patient with a fracture who has been restricted from exercise for a period of time would be prone to venous thrombosis, and pulmonary infarction could occur if the venous thrombosis falls out. 4.Severe elevation of blood pressure For patients with aortic coarctation, the onset sign is severe pain, and the pain will be accompanied by severe elevation of blood pressure. 5, chest pain As we all know, angina pectoris and heart attack are included in coronary heart disease, which has the highest rate of sudden death. The typical manifestation of coronary heart disease is chest pain, which usually occurs behind the sternum, the whole boundary is not very clear, its area will be appropriately large (about the same area as the palm of your hand), or it is not clear where the pain is, mainly the feeling of boring pain. After taking medicine for angina, the symptoms will be relieved in a few minutes to ten minutes. The stabbing pain of pins and needles or the “pressing pain” is often not related to the heart. If you are a person with a high pain threshold, and if your life is not very regular, perhaps you can do a heart subhealth test to measure your heart function.
