Myocardial infarction is acute and has a high mortality rate. Once the disease occurs, it will cause extensive ischemic and hypoxic necrosis of the myocardium, and it is difficult to return to normal, so that it is life-threatening in a short period of time. There is only a few hours of golden treatment time for myocardial infarction. Failure to rescue in time may bring lifelong regrets. The most terrible thing is the misunderstanding of acute myocardial infarction, which delays the rescue time of myocardial infarction.
What are the misconceptions about myocardial infarction?
1. There is no myocardial infarction without chest pain
retrosternal crushing pain is typical of acute myocardial infarction Symptoms, accompanied by profuse sweating. But not every myocardial infarction patient will experience chest pain, and myocardial infarction is prone to atypical symptoms, such as stomach pain, shoulder pain, tooth and jaw pain, etc. There is always unexplained pain in one area that lasts for a long time and requires immediate medical attention.
2. Patients with myocardial infarction must take nitroglycerin
The mechanism of action of nitroglycerin is Promote coronary dilatation and relieve angina pectoris caused by coronary spasm or coronary stenosis. However, when a myocardial infarction occurs, the blood clot has completely blocked the blood vessel, and taking nitroglycerin has little effect.
It is worth mentioning that not every patient can use nitroglycerin, In particular, increased intracranial pressure, less than 50 beats per minute, hypotension and glaucoma, cerebral hemorrhage, etc. If you feel chest tightness and chest pain, without the above contraindications, you can take nitroglycerin sublingually; if the symptoms still do not improve after about 3 times of medication, you should immediately call 120 for emergency treatment.
3. In the event of myocardial infarction, the nearest hospital is required
The focus of myocardial infarction treatment is To open the blocked blood vessels, in addition to paying attention to the distance from the hospital, the most important thing is the hospital’s ability to treat. It is ensured that the hospital can treat the disease as soon as possible, and if necessary, cardiac interventional surgery is required; if the nearby hospital has limited ability to treat the disease, it may be best to do thrombolytic therapy first, and then transfer to a large hospital.
4. When a myocardial infarction occurs, a hard elbow can save your life< /span>
Folk people say that when an acute myocardial infarction occurs, slapping the elbow hard or coughing hard can clear the blocked blood vessels. In fact, the heart is beating all the time, providing blood and oxygen to various tissues and organs in the body. In the event of myocardial infarction, the blood vessels supplying the heart are blocked, resulting in ischemic and hypoxic necrosis of myocardial cells. Coughing hard or slapping the elbows will actually speed up the heart rate, increase the burden on the heart, and easily cause the disease to worsen. In severe cases, it can induce cardiac arrest.
5. Go to the hospital by yourself
Some people think that waiting for an ambulance is a waste Time, it is better to drive yourself to a doctor, this is a wrong behavior. Acute myocardial infarction is a sudden onset and may be life-threatening at any time, and accidents may occur when you go to the hospital by yourself. The sensible way is to calm down and wait for the ambulance to arrive. Professional medical staff will treat it, which can ensure the safety of the transfer to the greatest extent.
Message from the doctor
Once acute myocardial infarction is suspected , You can’t take chances, and you need to seek medical attention immediately to minimize the size of myocardial infarction, protect heart function, and deal with various complications as soon as possible. Usually should pay more attention to rest, not to overwork yourself; not to lift heavy items, especially elderly patients with coronary heart disease, so as not to induce acute myocardial infarction due to excessive force. At the same time, keep calm, and don’t be too greedy in summer.
