Every year in the cold winter is a high incidence of sudden myocardial infarction, and if there is a sudden heart attack at home, timely self-help is a very important aspect, those various "self-help methods" spread on the Internet, which are really reliable, and what are the precautions? Today's popular science article, let's talk to you about the relevant topics in this regard.
In the cold weather of winter, be alert to the risk of sudden heart attack
The heart is the "engine" of our body's blood circulation, and the work of the heart itself also needs sufficient energy and nutrient supply, therefore, the blood vessel network that supplies blood to the heart is an important part of ensuring the normal operation of the engine, if the blood vessels that supply blood to the heart are blocked, it will form a "myocardial infarction" problem, when the myocardial infarction occurs, the blood supply to the heart is interrupted, if the blood supply cannot be restored in time, the risk of cardiac function damage is light, and the heavy causes the electrophysiological disorder of the heart, causing ventricular fibrillation, and cardiac arrest is life-threatening.
Cold winter weather, is the risk of cardiovascular disease patients sudden myocardial infarction of high-risk period, the human body in order to resist the cold, myocardial oxygen consumption will be greater, and under the cold stimulation, will also make the blood vessels constrict, increase the risk of blood pressure increase, blood flow rate will also be correspondingly slower, blood coagulation in the blood is also easier to accumulate, and under the influence of some sudden cold stimulation or other factors, the occurrence of arteriosclerosis plaque rupture, the formation of thrombosis blockage coronary artery blood vessels The probability of blocking coronary arteries will also increase, therefore, in the winter cold weather, For patients with coronary heart disease who have a high risk of cardiovascular disease, especially those with severe arteriosclerosis, special attention should be paid to the risk of sudden myocardial infarction.
Sudden myocardial infarction, correct identification is important
In fact, although the chest pain that cannot be relieved is a typical symptom of sudden myocardial infarction, there are many times when myocardial infarction occurs, the pain site is not necessarily in the precordial area or behind the sternum, especially when some diabetic patients suddenly have a myocardial infarction, it is often not accompanied by obvious chest pain symptoms, and when the myocardial infarction occurs, the pain site may also occur in the back, upper abdomen, shoulders, neck, jaw and even the left lower limb, groin and other parts Therefore, do not think that without chest pain, it is not a myocardial infarction attack, and about one-third of myocardial infarction patients have symptoms that are not typical.
In addition to pain symptoms, it is more noteworthy that accompanied by the occurrence of myocardial infarction, often accompanied by severe chest tightness, breath holding feeling, due to severe ischemia of the myocardium, often sweating, feeling of imminent death and other feelings, if it is itself a patient with coronary heart disease or previous attacks of myocardial infarction, if the above symptoms occur, accompanied by pain in various different parts of the above, and there is no fixed tender point, the possibility of sudden myocardial infarction should be considered.
Sudden heart attack, a variety of self-help methods spread on the Internet, which is reliable?
When a sudden myocardial infarction, active self-help is very important, with the correct and reasonable way to deal with myocardial infarction, can greatly increase the chance of patients to get treatment, but for some of the widely circulated "myocardial infarction self-help methods", which is the right one? Let's introduce them to you one by one.
1, slap the chest - mistake
Some friends take it for granted that slapping the chest can "shoot away" the blocked blood clot or alleviate the symptoms of chest tightness and breath holding, but in fact, this way of slapping hard is not the correct way to save yourself from myocardial infarction. When the heart attack comes, minimizing the oxygen consumption of the heart, avoiding strenuous activity, is the right way, hard to pat the chest, not only will not alleviate the chest pain chest tightness discomfort symptoms, but also may be because of the increase in activity and aggravate the disease.
2. Slap the inside of your arm – wrong
This method is also a long-standing method, and even related video teaching, saying that slapping the inner elbow socket of the arm can help open up blood vessels and be used for myocardial infarction first aid, but in fact, this method is more unreliable, whether it is yourself or others, slapping hard inside the arm, will cause pain, stimulate human sympathetic excitement, increase the number of heartbeats, increase heart consumption, in addition to bringing greater risks to heart health, it will not play a role at all.
3, acupuncture and bloodletting method - wrong
Acupuncture ten fingers bloodletting and acupuncture earlobe bloodletting and other methods, but also spread very widely, but in fact, when the real myocardial infarction comes, acupuncture related parts of the bloodletting, in addition to being able to bring pain stimulation to patients, can not play a role in improving blood vessel blockage, acupuncture ten fingers of the method, in ancient times called "ten Xuan acupoint bloodletting", mainly in ancient times in the absence of medical means, used to stimulate the awakening effect, is an auxiliary treatment means, can not be used as a self-help method for myocardial infarction patients!
4, forceful cough method - wrong
There are rumors that when a myocardial infarction occurs, deeply, forcefully, non-stop coughing can save your life, this statement is actually not reliable, so that coughing can indeed accelerate coronary blood flow, but for the coronary arteries that have been infarction, coughing hard can not play a role in unclogging blood vessels, nor can it alleviate the risk of ventricular fibrillation caused by myocardial infarction, and severe coughing may also cause blood pressure to rise, and it is not a self-help method suitable for myocardial infarction.
5, eat nitroglycerin or quick-acting heart-saving pills - ineffective
If it is the onset of coronary heart disease angina, rapid taking nitroglycerin or quick-acting heart-saving pills can play a relieving effect, but if after sufficient rest or taking nitroglycerin or quick-acting heart-saving pills, it is still effective to get relief within 20 minutes, in this case, it should be highly suspected that it is a myocardial infarction attack, and then take nitroglycerin or heart-saving pills, it is not necessary, and may also bring about the risk of hypotension.
6, eating aspirin - improper use is risky
Aspirin is a drug that can play an anti-platelet aggregation effect, in the case of myocardial infarction, can taking aspirin play a self-help role? First of all, it should be clear that if it can be accurately judged that it is indeed a myocardial infarction attack, at this time, quickly chew (please pay attention to chewing and taking, not swallowing) 300mg of aspirin, can play a role in reducing the aggregation of coagulated substances and reducing the risk of thrombosis.
However, it should be noted that not all chest pain is a myocardial infarction attack, if the patient has tear-like, knife-like severe pain, but also accompanied by serious hypertension problems, the risk of aortic dissection should also be considered, and some diseases such as cardia mucosal tears, etc., will also cause severe chest pain, in this case, chewing aspirin, not only ineffective for relieving chest pain, but also may bring risks to subsequent treatment. Therefore, whether to chew aspirin, should be used under the premise of accurately judging that it is indeed a myocardial infarction.
7) Go to the hospital yourself – wrong
When some friends have a sudden heart attack, they can endure discomfort and go to the hospital for treatment on their own, which is also a wrong practice. When a myocardial infarction occurs, the risk of going to the hospital on your own is very high, and when a myocardial infarction occurs, minimizing activity is a very important aspect, and in the process of going to the hospital, the increase in activity will bring risks, and there may also be ventricular fibrillation on the way, the risk of cardiac arrest and the lack of first aid measures.
8. Dial the 120 emergency number in time and wait for rescue
This is the real right approach, for sudden chest pain, suspected patients with myocardial infarction, should immediately dial the 120 emergency number, while lying well or relying on it to do a good job, waiting for the arrival of medical personnel, minimizing activities, if it is alone at home, you should immediately call your relatives, please call your relatives quickly to dial the 120 emergency number, and open the door, so that emergency personnel can not enter.
All in all, in the case of a heart attack, minimizing activity and getting first aid in time is the right thing to do, do not listen to rumors, delay the best time for treatment.
