Hello! I am Liu Jian
Today is the 593rd issue that Jian Ge said to accompany you
As we all know, myocardial infarction is a "fatal" emergency and severe illness, but in the face of suspected myocardial infarction, many people will walk into the misunderstanding, today, we will take a look.
Myth 1: Is no chest pain not a myocardial infarction? not necessarily!
Chest pain, the most typical symptom of acute myocardial infarction, manifests as a crushing pain in the middle or left side of the chest, like a boulder pressed against the chest. Patients are often accompanied by heavy sweating and get soaked in a few minutes.
Of course, the above symptoms are not 100% myocardial infarction, and the absence of these symptoms does not mean that it is certainly not myocardial infarction.
In fact, some patients with acute myocardial infarction do not have chest pain, they may have pain or discomfort in certain parts of the range from the lower jaw down to the abdomen upwards, such as toothache, jaw pain, shoulder pain, stomach pain and so on. If there is persistent pain in the above areas that is not triggered, be sure to go to the hospital.
Myth 2: Must I take nitroglycerin for myocardial infarction? No!
Nitroglycerin can dilate coronary arteries and improve angina due to coronary artery spasm or narrowing, but if myocardial infarction occurs and blood vessels are completely blocked by blood clots, the effect of nitroglycerin on relieving symptoms may not be obvious.
At the same time, it should be understood that some patients cannot take nitroglycerin, such as glaucoma, hypotension, cerebral hemorrhage, increased intracranial pressure, slow heart rate (< 50 times / min) or too fast (> 100 times / min), allergy to nitroglycerin, or taking sildenafil (commonly known as Viagra) within 24 hours.
Therefore, if the patient has chest pain, chest tightness, and there is no above contraindications, you can take nitroglycerin under the tongue, 1 tablet each time, the effect is not good for 5 minutes and then take 1 time, do not take more than 3 times.
Myth three, myocardial infarction must go to the nearest hospital? not necessarily!
The core of myocardial infarction treatment is to open the blocked blood vessels as soon as possible, and the choice of hospital should consider both distance and hospital treatment capacity. Hospitals with the words "chest pain center" at the entrance of the hospital or in the emergency room have the ability to treat myocardial infarction, not only establishing a rapid diagnosis and treatment channel, but also the cardiac intervention ability, and patients can get more timely and effective treatment. If there is no chest pain center nearby, you should go to the nearest hospital for emergency treatment, such as thrombolytic therapy, and then consider transporting to a hospital with a condition. If you have a chest pain center near your home, you should be congratulated and see a doctor as soon as you develop chest pain.
Myth 4, find an ambulance to delay the time, why not go to the hospital by yourself? mistake! To dial 120!
Some people think that waiting for an ambulance is more delayed than driving to the hospital by yourself, but in fact, it is very dangerous to do so. Patients with acute myocardial infarction are life-threatening at any time, and if they go to the hospital on their own, once there is an emergency on the way, there is a possibility of serious consequences without any treatment capacity and equipment. In ambulances, there are professional rescue personnel and equipment to transport patients more safely.
Therefore, if a myocardial infarction is suspected, the first time should be to dial 120 and take an ambulance to the hospital.
Myth five, when I arrived at the hospital, I went to the outpatient clinic to wait for treatment. Don't!
Some patients have chest pain and come to the hospital on their own, but they also go to the outpatient clinic to wait for treatment, which is equivalent to wasting the treatment time of myocardial infarction.
Myocardial infarction treatment can not wait, to the hospital must hang up the emergency department. As a hospital with chest pain center, a green channel is opened for chest pain patients, and the patient's examination and diagnosis and treatment should be completed within the specified time, generally requiring the completion of the first electrocardiogram within 10 minutes, the completion of blood markers of myocardial infarction within 20 minutes, and the completion of chest CT and cardiac ultrasound within 30 minutes.
Therefore, if myocardial infarction is suspected, it is necessary to go to the emergency department to race against the clock for treatment.
Brother Jian said
Acute myocardial infarction is a life-threatening emergency and severe illness, which requires learning to identify symptoms and racing against time for treatment.
Myocardial infarction does not necessarily cause chest pain, and if there is no precipitating cause of persistent toothache, stomach pain, shoulder pain, accompanied by symptoms such as sweating and chest tightness, vigilance is required.
Once acute myocardial infarction occurs, it is crucial to open the blood vessels as soon as possible, and you must dial 120 immediately, not to go to the hospital yourself, and you should not go to the outpatient clinic.
There are four common misunderstandings about the treatment of acute myocardial infarction, and we will talk about it next time.
Today's content is finished, and the next issue is more exciting.
