Reminder: Recognize the 5 major misunderstandings of myocardial infarction! Doctors advise everyone to understand early, it can save lives at critical moments

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

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.
