As the climate gradually turns cooler, the prevalence of “heart attack” increases due to climatic factors, but effective thrombolytic therapy within 6 hours of the onset of “heart attack” can not only improve the cure rate of the disease, but also contribute to the quality of life of patients. In order to obtain treatment within the effective time, we should not ignore the signs before the onset of “heart attack”. “Heart attack” is the abbreviation of coronary heart disease myocardial infarction, nowadays “heart attack” is no longer the patent of the elderly, the media reports about young elites dying from “heart attack” are common, it is worth What is of concern is that the onset of “heart attack” in middle-aged people is more sudden and the mortality rate is higher than that of the elderly. For this reason, how to predict the occurrence of “heart attack”, catch the subtle symptoms before the “heart attack” and take preventive and curative measures as early as possible has become one of the common concerns of the public. 9 factors induce “heart attack” Research shows that more than 90% of heart attacks are induced by risk factors such as dyslipidemia, smoking, diabetes, hypertension, stressful conditions, insufficient intake of fruits and vegetables, lack of exercise, abdominal obesity, excessive alcohol consumption, etc. Thus, it can be seen that most cases of “heart attack “It can be predicted and prevented in most cases. 5 traces before the occurrence of heart attack Not all “heart attack” episodes have aura in the clinic, but usually 50% to 80% of people will have some warning aura symptoms before the “acute heart attack” episodes, and the aura usually occurs for 1 to 2 days or longer The aura usually occurs for 1 to 2 days or more. If we pay attention to the aura symptoms, we can effectively avoid the crisis of “heart attack” if we find the trace of aura symptoms in advance and seek medical treatment in time. Chest pain at night or at rest: When the pain in the precordial region occurs at rest or at night, you should be highly suspicious of “heart attack” episodes, generally new angina at night or after rest, are the precursors of “heart attack” episodes. People who have suffered from angina in the past should be highly alert to an attack of “heart attack” if their angina symptoms have gradually increased in the past month, or if the number of chest pains is more frequent than before, the degree of chest pain is getting heavier, the range of chest pain is greater and the duration is longer. In addition, when the chest pain symptoms cannot be effectively relieved within 15-20 minutes after taking nitroglycerin under the tongue during an angina attack, we should also be alert to the appearance of “heart attack”. Chest pain without obvious triggers: In the past, although angina could be found with obvious triggers, such as after exertion and excitement, nowadays, chest pain occurs in a quiet state without obvious triggers, accompanied by profuse sweating, vomiting, nausea, etc., and prompt medical attention is required. Sudden panic and stuffiness: If you have never experienced chest tightness, weakness, or panic before, or if you experience panic or shortness of breath during activity or if your symptoms worsen and tend to get worse, you should seek medical attention immediately. Pain in other parts of the body related to exertion: The phenomenon of somatic pain is associated with exertion and excitement, and may appear in epigastric pain, toothache, jaw pain, left shoulder and arm pain, back pain, etc., which should also be taken seriously. In addition, middle-aged and elderly people should be on high alert for “heart attack” if they suddenly develop acute left heart failure, cardiogenic shock, or severe arrhythmia that cannot be explained by other diseases or causes. TIPS – Do not ignore atypical “heart attack” episodes Many “acute heart attack” episodes are not obvious symptoms, especially in women, about 65% of women in About 65% of women will have a variety of manifestations during an “acute heart attack”, which is easy to ignore not only by the patients themselves, but also by the doctors. Symptoms such as sudden and increased dyspnea, nausea, vomiting, toothache, jaw pain, headache, dizziness, insomnia, extreme fatigue, poor appetite, indigestion, stomach pain, anxiety, etc. Patients with original respiratory problems should also be highly suspicious of a sudden “heart attack” if they suddenly experience unexplained difficulty in breathing, coughing, coughing up foamy sputum and other conditions. If these symptoms are associated with exercise, exertion or excitement and last for more than 20 minutes, you need to seek medical attention promptly. The three high people are careful of heart attack There are triggering factors for the occurrence of any disease, and for “heart attack”, the people who need to be extra vigilant are those with more triggering factors. Patients with high blood pressure, diabetes and dyslipidemia are more likely to have accidents. If the body is often in a state of overload fatigue, or too much emotional tension, more likely to trigger a “heart attack”. In addition, people who smoke, drink, and eat fatty and sweet food should also be especially careful of “heart attack”. Heart care, prevention of “heart attack” should start from the lifestyle, change the bad habits. Special reminder: “heart attack” high-risk groups, it is best to drink a glass of water before going to bed, in order to better dilute the blood. Since many “heart attack” patients have an attack in the morning, so there are 3 notes before getting up in the morning: 1, do not get up immediately after waking up, but lie quietly in bed for 3 minutes before sitting up; 2, after sitting up, do not immediately get off the ground, but sit quietly in bed for about 3 minutes before getting out of bed; 3, after getting out of bed, do not move at that time, but can pause a little After a while, then slowly move around. This is to allow the body to fully adapt to the process from static to dynamic, which is conducive to the prevention of “acute heart attack” suddenly occurred. TIPS – the values to be achieved to prevent heart attack Usually, the body is within the following values, the chances of heart attack will be much smaller: body mass index (BMI): between 18.5 and 24, [body mass index calculation method: weight (kg)/height (m2) squared]; blood pressure: less than 120/ 80 mmHg (systolic/diastolic), or 16/10.6 Kpa; fasting blood glucose: between 80 and 100 mg/dl, or 4,4-5.6 mmol/L; blood lipids: total cholesterol not more than 200 mg/dl, triglycerides not more than 150 mg/dl, LDL not more than 130: mg/dl, HDL not less than 40 Waist circumference: not more than 80cm for women and not more than 90cm for men. The main reason for “heart attack” is that some large particles of blood (e.g. fat particles) are deposited in the inner wall of the broken blood vessels after the endothelium of the arteries supplying blood to the heart is damaged. Once the plaque is dislodged, it becomes a thrombus, and when the thrombus blocks the blood vessel, it causes myocardial ischemia and leads to myocardial infarction. Because of this, thrombolytic treatment within 6 hours after the occurrence of vascular blockage can cause reversible damage to the heart and can be repaired in time, which not only can get very good treatment but even reduce the number of myocardial necrosis and effectively improve the quality of life. However, if the best treatment time is exceeded, the harm will be unpredictable. It is clinically found that about half of the patients die before they are sent to the hospital after an “acute heart attack”. How to grasp the 6 hours of life and death is the key to save the “heart attack” patients, and timely detection of the signs before the “heart attack” is even more important.
