Acute myocardial infarction, a serious cardio-cerebrovascular disease with high incidence in winter, is just like Specter, becoming a “cold-blooded killer” that takes life. Especially in cold nights in winter, this specter appears more frequently. For the past two weeks, the hospital’s emergency department has been seeing several patients with severe acute myocardial infarction almost every day. However, acute myocardial infarction is not without warning, but many patients do not notice. Many people always have lucky psychology: chest tightness, chest pain endure a endure, the top over. Little do they know, it is because of such fluke psychology, delay the best treatment time, paid a painful price.
Watch out for fatal chest pain! Emergency medicine department chief physicians remind: emergency time to understand the heart distress signal, there are high blood pressure, high blood lipid, diabetes and smoking people, when there is chest distress, chest pain, upper abdominal discomfort, if the duration of more than 15 minutes, it is necessary to be very careful, should immediately go to the hospital.
Listen: this is the heart calling for help!
Myocardial infarction, it is coronary artery occlusion, blood flow interrupt, make myocardium because of serious persistent ischemia, hypoxia and occur necrosis, can concurrent arrhythmia, shock or heart failure, endanger life, it is the most critical heart acute disease at present. What are the “telltale signs” before a heart attack? The typical symptom of myocardial infarction is severe chest pain, mainly manifested as severe pressing pain behind the sternum or in the anterior area of the heart, usually more than 10 minutes, can radiate to the left upper arm, jaw, neck, back or shoulder, often accompanied by nausea, vomiting, sweating and dyspnea.
1,The sudden occurrence of angina pectoris in patients without angina pectoris in the past, or the onset of angina pectoris in patients with original angina pectoris suddenly significantly aggravated, or spontaneous onset without inducement;
2, the nature of angina pectoris changed than before, the time is prolonged, the use of nitroglycerin is not easy to ease;
3, pain accompanied by nausea, vomiting, sweating or obvious bradycardia or tachycardia;
4, angina attack accompanied by shortness of breath, dyspnea;
5, coronary heart disease patients or the elderly suddenly unidentified arrhythmia, heart failure, shock or syncope and other conditions should think of the possibility of myocardial infarction.
In addition, there are sometimes atypical “signals” of symptoms:
1, shoulder and back pain: in the case of no injury to the body, shoulder pain, back pain, even the whole finger, wrist pain.
2, chest pain: the sudden presence of pain or chest tightness in the left front of the heart, like a boulder pressed on the chest, and can be traction or radiation to the shoulder and arm.
3,Abdominal pain: gastrointestinal symptoms of unknown cause, such as nausea, acid, vomiting, fullness, upper abdominal pain, burning sensation in the stomach, etc., especially intermittence after increased activity.
4, toothache: myocardial infarction can sometimes be toothache or mandibular pain, attack suddenly, may be in emotional excitement, excessive fatigue or after a full meal; But toothache place is not exact, after the dental treatment and take painkiller still cannot lift. Moreover, this kind of toothache is not painful in the resting state, but will be painful after walking, exercise.
5, no symptoms of palpitation and chest tightness: usually no heart disease people suddenly appear chest tightness, palpitation, shortness of breath, irritability, unexplained afflictiveness, inactivity also appear stuffy, panting.
6,Painless myocardial infarction: Those with a history of chronic obstructive pulmonary disease, diabetes or cerebrovascular disease, such as sudden cough and asthma, chest distress, shortness of breath, syncope and other manifestations without inducement, should think of the possibility of painless myocardial infarction, especially diabetic patients, should see a doctor immediately.
Take a: heart attack raid, calm response!
What should you do when you hear a distress call from your heart? When heart attack burst, how to save or save? Don’t panic, remember that, and stay calm!
Experts remind, when suspected acute myocardial infarction, please keep in mind: once the occurrence of chest distress, chest pain and lasts more than 15 minutes, nitroglycerin can not alleviate, acute myocardial infarction should be highly suspected, to immediately call 120, stop activities, suggest bed rest or lying on the spot; Active control of tension; If conditions permit, oxygen can be inhaled; Don’t take the medicine carelessly.
Knock on the blackboard: draw three key points!
Call emergency services immediately! The rescue of acute myocardial infarction can be said to be time is life, therefore, to the first time to dial emergency phone, this is an important step to save life! Choose to drive private cars, taxi, bus and other ways to go to the hospital, are not suitable and too dangerous. The ambulance is the first step in the green channel, to save on myocardial infarction in hospital process, for example, medical personnel can not only the scene first aid, maintain vital signs, also can be in the car to complete the electrocardiogram (ecg), transport to a hospital central chest pain, the ambulance will be diagnosed, formulate emergency strategy, prepare for subsequent treatment.
Do not lift the patient!
When someone with a heart attack falls to the ground because of chest pain, many people try to help the patient up, but this is “deadly”. It is important to note that, no matter where the onset of the disease should be immediately lying flat, because the body supply of blood to the heart is the most supine, coronary artery ischemia itself, standing and sitting will make the heart ischemia more serious.
How to take life-saving medicine?
Nitroglycerin: myocardial infarction feels similar to angina pectoris, difficult to distinguish. If nitroglycerin under the tongue can relieve angina pectoral pain, but if the symptoms do not improve after taking 3 tablets at 5 minute intervals, be alert to the possibility of myocardial infarction. Stop taking the nitroglycerin immediately and call the emergency services. Inform the doctor of the amount and condition of nitroglycerin the patient has taken. It should be noted that nitroglycerin is ok to take, but should not be taken too much, otherwise it will make blood pressure lower and lower.
Aspirin: Many families give patients aspirin while they wait for the ambulance to arrive. But be careful, do not swallow, chew aspirin. Aspirin inhibits platelet aggregation and prevents further expansion of the clot. When aspirin is used for emergency treatment of myocardial infarction, it should be chewed and taken in order to exert its effect in the shortest time.
Read: safe winter warm reminder!
Winter heart attack high incidence, exactly is why? Can you avoid the risk? Cardiovascular and cerebrovascular diseases are prone to occur in winter. There are several major causes:
1,Vasoconstriction: the temperature difference between morning and evening in winter is large, the physiological response of the human body is relatively slow, and it is often in a state of stress; At the same time, under the cold stimulation, the small blood vessels of the human body will be in the state of contraction, the myocardial oxygen consumption will also increase, the heart burden is heavier, easy to induce myocardial ischemia.
2,Lifestyle change: In cold weather, people do less outdoor exercise, and at the same time, they increase the intake of high-calorie food such as meat, resulting in the imbalance of energy intake and metabolism, increased blood viscosity, slowed blood circulation, and easy to form thrombosis, leading to myocardial infarction.
3,Constipation: In cold weather, the elderly hold their breath when defecation is difficult, which increases the abdominal pressure and causes the sudden rise of blood pressure, which is easy to induce angina pectoris and myocardial infarction.
In short, want to be safe in winter, should do so!
1,Keep warm outdoors, especially for your head, hands and feet. Do not take off your clothes and hats after entering the room, and try to reduce the fluctuation of blood pressure.
2,do brisk walking, jogging and other moderate aerobic exercise for about half an hour every day, about 150 minutes a week, avoid strenuous exercise.
3, each meal is best to eat seven or eight points full, reduce animal organs and other high triglyceride, high cholesterol food intake. Especially dinner, do not eat too full.
4,Even if the stool is dry, do not exert too much force. If necessary, it can be assisted by external medicines such as open plug dew. Eat more fresh fruits, vegetables and whole grains rich in dietary fiber, drink more water and exercise.
5,Patients with hypertension and diabetes should pay attention to monitoring the changes of blood pressure and blood glucose, adjust medication in time, and control the above indicators;
6, avoid emotional, don’t stay up late at work, keep calm;
7, try not to go to crowded places, go out to wear a good mask and hat, appropriate clothing, to avoid a cold.
