6 big signs before sudden death, be sure to pay attention

  In recent years, the prevalence of cardiovascular and cerebrovascular diseases has been increasing, and the incidence of sudden death has increased. Many public figures such as actors Gao Xiumin, Gu Yue, and Ma Ji have passed away due to sudden death. The main cause of sudden death is sudden cardiac death, including cardiac arrest or acute heart failure caused by coronary heart disease or other malignant arrhythmias. Among them, sudden death caused by coronary heart disease can account for 80%. In addition, some cerebrovascular diseases can also cause sudden death. Although sudden death happened suddenly, there are actually traces to follow.
High pressure occupations are prone to occur

  Sudden cardiac death includes two concepts: one is cardiac; the other is sudden death. Cardiogenic refers to heart diseases, such as acute myocardial infarction, heart failure, malignant arrhythmia and other diseases that we are familiar with, which occur under the inducement of overwork. Sudden death is a sudden death, currently defined as the occurrence of acute symptoms, death occurring immediately or within 24 hours. According to data from the National Cardiovascular Disease Center, the incidence of sudden cardiac death in my country is about 41.8 cases per 100,000 people. In other words, nearly 1,500 people suffer from sudden cardiac death every day.
  According to related studies, the occurrence of sudden cardiac death is mainly related to the following factors:
  1. Occupation. For example, corporate bosses, actors, and teachers with high work pressure are all vulnerable groups, especially urban “three highs” men aged 35 to 60. People with diabetes, obesity, smoking, high uric acid, low physical activity, and family history of cardiovascular disease are also high-risk patients of sudden cardiac death.
  2. Season. Due to the muggy weather in midsummer, people sweat more, blood concentrates, and blood viscosity increases. Thrombus and embolism are easy to form and cause sudden death. In winter, due to the stimulation of the cold on the body, the excitability of the sympathetic nervous system increases, and the secretion of catecholamines in the body increases, which can cause the blood vessels of the human limbs to contract, the heart rate increases, and the workload of the heart increases and induces sudden death.
  In addition, sudden cardiac death mostly occurs at night and early morning. Among them, the incidence in the early morning is three times that of the evening. During this period of time, blood pressure rises, blood flow accelerates, blood impacts on arterial plaques, platelet activity and coagulation function increase, and the body is at the peak of adrenal cortex hormone secretion. Factors such as changes in autonomic nervous system tension are related.
6 signs to pay attention to before sudden death

  A summary of clinical observations found that before sudden death, patients often had the following 6 major signs:
  1. Chest tightness that appeared or worsened recently. If you suddenly experience chest tightness after activity in the near future, rest for a period of time can relieve it. This phenomenon indicates that you may have coronary heart disease. Sudden symptoms indicate that the atherosclerotic plaques in the coronary arteries are not stable and may rupture at any time, leading to acute myocardial infarction. If you have occasional symptoms of chest tightness in the past, and the recent symptoms have become more frequent and more severe, it also shows that the previously stable plaque is now showing small damage and will develop into large damage at any time, leading to acute myocardial infarction occur. In this case, you should go to the hospital as soon as possible for medical treatment or surgery.
  2. Flustered. Palpitations are often the subjective feelings of increased heart rate. Unscheduled heart rate increases are usually the result of tachyarrhythmias. Most arrhythmias are less dangerous and will not cause sudden death, but if it is frequent ventricular arrhythmia, there is a risk of developing ventricular fibrillation. In addition, atrial fibrillation causes palpitation in many elderly people. If atrial fibrillation is accompanied by heart conduction disease, it can easily progress to ventricular fibrillation. After an onset of ventricular fibrillation, death can occur within minutes. Therefore, frequent heart attacks should also be treated promptly.
  3. Slow heartbeat. The beating of the heart is initiated by specific pacemaker cells, and the deterioration of the pacemaker cell function will cause the heart’s beating rate to slow down, and in severe cases, it will cause cardiac arrest. The function of pacemaker cells gradually deteriorates with age. With the continuous improvement of life expectancy in my country, the proportion of elderly people over 80 years old is also increasing. The function of pacemaker cells in this group will gradually deteriorate and the heart rate will gradually slow down. The elderly are usually less active, and the slower heart rate can also maintain normal life needs, so they are often ignored. Elderly people should monitor blood pressure and heart rate regularly. If the heart rate is less than 50 times and the blood pressure becomes low, it is prone to prolonged cardiac arrest and sudden death.
  4. Syncope. Syncope is an important precursor of sudden death. Most of the syncope is caused by the sudden slowing or stopping of the heartbeat, resulting in insufficient blood supply to the brain. Common causes include sinus node disease, atrioventricular block, and hypertonic vagus nerve. Syncope sometimes recovers on its own after a few seconds, and if it fails to recover, it will cause sudden death. Therefore, after unexplained syncope, you should be alert and find out the cause as soon as possible to prevent the next syncope or even sudden death.
  5. Unexplained fatigue. Sudden death is not the patent of the elderly, and it can happen to the young. Many young people are under pressure at work and often experience fatigue, which is normal. But if there is unexplained fatigue, fatigue, or chest tightness, edema, you should be alert to sudden death, this situation may be caused by myocarditis or cardiomyopathy. Myocarditis is more common in young people. It is common after 1 to 2 weeks of catching a cold, and symptoms such as fatigue, chest tightness, and fatigue appear, which can easily cause acute heart failure. In this case, it is strictly forbidden to do heavy physical activity and rest in bed. Cardiomyopathy is mostly a hereditary disease, which is not easy to detect at an early stage. Irreversible changes in myocardial structure have occurred when symptoms appear, such as enlarged heart and myocardial hypertrophy, which can easily cause sudden death. Therefore, when there is unexplained fatigue and chest tightness, one should be highly alert to the occurrence of myocarditis and cardiomyopathy.
  6. Black eyes and numb limbs. Stroke is also an important cause of sudden death. Some strokes have a sudden onset, paralysis of the limbs and increased blood pressure within a few minutes. In this case, the patient can save lives if he sees a doctor in time. However, some strokes have a slow onset, with only mild symptoms in the early stages, and the patients do not care. Once progressed may cause sudden death, so you need to pay more attention. Especially in patients with hypertension, coronary heart disease or atrial fibrillation, the incidence of stroke is several times higher than that of the general population. If you cannot see things on one side, numbness or weakness on one side of your limbs, or if you walk unsteadily, or have a feeling of stepping on cotton, you should be alert to the occurrence of stroke and seek medical treatment in time. Early identification can often achieve better results.
  People at high risk of cardiovascular and cerebrovascular diseases need to be vigilant at all times for physical discomfort. When abnormalities occur, they must respond quickly and seek medical attention in time to prevent sudden death.
