Sudden death, which occurs all around us from time to time, occurs more frequently in men than in women. There are two age peaks when sudden death occurs, one between the birth of a baby and 6 months of age, and the other between 65 and 75 years of age. Let’s take a look at what are the common diseases that cause sudden death. Heart disease, coronary heart disease Many people are not diagnosed because they have not had an electrocardiogram or coronary angiogram and other tests, and the disease is not treated promptly and effectively, often easily leading to sudden death after acute massive myocardial infarction occurs under certain causative factors. In addition, other heart diseases, such as myocardial ischemia, aortic coarctation aneurysm, aortic stenosis, and malignant arrhythmia, are also the causes of sudden death. Pulmonary embolism Due to the continuous improvement of examination methods, the incidence of pulmonary embolism is increasing, and it occupies an important position in the causes of sudden death in the elderly. Some of them are also prone to pulmonary embolism because of the long time of bed rest and little activity due to the disease. Once blockage of the larger branches of the pulmonary artery occurs, fatal consequences can occur, and the success rate of resuscitation is low. Cerebrovascular disease The majority of patients with cerebral hemorrhagic disease have a vascular disease base, and hypertension, diabetes and atherosclerosis are common causes. Under the adverse stimuli such as emotional excitement, smoking and alcohol, blood pressure can often be caused to rise sharply, resulting in blood vessel rupture. A small amount of bleeding can be treated in a hospital and can save life. Digestive tract diseases Among them, hemorrhagic necrotizing pancreatitis leads to sudden death, while upper gastrointestinal hemorrhage and other sudden death can also occur. Sudden bleeding at night causing shock or asphyxia caused by vomit obstructing the throat are often the main causes of sudden death due to upper gastrointestinal bleeding. Hypoglycemia Sudden death at night due to severe hypoglycemia is also more common in elderly diabetic patients. The reason for this is that a considerable number of elderly diabetic patients are not treated regularly or do not eat in time after receiving glucose-lowering treatment; some patients have large changes in blood sugar levels, and hypoglycemia often occurs at night, which is not easy for patients to detect and leads to sudden death. Most of the sudden death patients have clear “trigger” factors, including excessive fatigue, emotional excitement, mental stress, alcohol abuse, full meals, strenuous exercise, cold, cold drinks and so on. Therefore, it is important to pay more attention in daily life.
