Regarding myocardial infarction, what is myocardial infarction?

Give him nitroglycerin. If you have it with you or if it's easy to get by.

The second is to find a car and send it to the nearest hospital.

If you are far away, call 120 and wait for an ambulance.

Myocardial infarction refers to the interruption of blood supply to myocardial tissue caused by acute and persistent occlusion of the blood vessels that innervate the myocardium called the coronary arteries, resulting in myocardial tissue necrosis. The most common cause of acute myocardial infarction is coronary arteriosclerotic heart disease, and other causes such as spasm and embolism can also cause myocardial infarction. Acute myocardial infarction caused by coronary heart disease is often based on the narrowing of the lumen caused by coronary arteriosclerotic plaque, resulting in insufficient blood supply, and acute thrombosis leads to the interruption of myocardial blood flow and causes myocardial cell necrosis.

Once the patient is diagnosed with acute myocardial infarction, it is necessary to actively open the blood vessels, restore coronary blood flow, and prevent the patient from sudden death and cardiac insufficiency. For patients with myocardial infarction, time is life, and time is myocardium. In particular, emergency intervention and stent implantation are the most effective methods for acute myocardial infarction.

At present, it has been widely used in China, including in county-level hospitals, saving the lives of a large number of patients.

The so-called myocardial infarction, also known as myocardial infarction, refers to the blockage of the patient's coronary arteries, which then induces complete occlusion of the coronary arteries, resulting in no way to perfuse the blood flow, causing serious consequences of myocardial necrosis, which is a disease that is enough to cause the patient to lose his life.

Yi Anning mainly treats coronary heart disease, angina, myocardial ischemia, hyperlipidemia, atherosclerosis, myocardial infarction, arrhythmia, arrhythmia, ventricular fibrillation, atrial fibrillation, heart failure and other heart diseases. It has good effects on stroke hemiplegia** and after stent lapping**!

The coronary blood vessels that supply blood to the heart are blocked by blood clots, and the myocardium is deprived of blood and nutrients** resulting in necrosis. Simply put, it is myocardial infarction.

The factors that induce myocardial infarction include bad lifestyle habits, constipation and drug factors, etc., which are very easy to induce myocardial infarction in life, especially bad living habits, staying up late for a long time, or smoking a lot, or drinking a lot of strong coffee, these bad habits may induce the acute occurrence of myocardial infarction.

Maybe many of us will always hear all kinds of information in our lives, such as what reason a certain star induces myocardial infarction and eventually dies, in fact, in life, many of us often work a lot of overtime, or keep staying up late, or constantly drink a lot of strong coffee in the process of staying up late, in fact, these factors will directly induce myocardial infarction and death to a large extent, and constipation will also directly lead to induce myocardial infarction. This is the result of a large number of clinical studies, and this is a very important factor, so it must be avoided in time.

The reason why many elderly people will have myocardial infarction in their lives also includes acute myocardial infarction caused by the shedding of atheroma after emotional agitation, so patients with heart disease must not have any emotional agitation in life, and must keep themselves calm enough and not let themselves be too excited, of course, there are many drug factors that can also lead to the occurrence of myocardial infarction, such as the use of some cold medicines containing ephedrine, This drug can cause sympathetic overexcitation and tachycardia, which causes myocardial infarction is also very common, and the consequences are also very serious, so it is necessary to maintain good lifestyle habits and strengthen exercise in life.

In life, we must maintain good living habits, do not work overtime, do not stay up late, do not drink a lot of strong coffee, we must actively maintain our health, no matter how much money we make, there is no way to buy our own health, so we must always keep in mind that we must strengthen the exercise, and do not stay up late.

The most common cause of myocardial infarction is due to coronary atherosclerosis, as well as patients with regular smoking, alcoholism, diabetes, dyslipidemia, overweight and agitation, weather changes may induce myocardial infarction, as well as coronary artery spasm, severe hypotension, anemia, and it is easy to cause myocardial infarction in patients, or due to arrhythmia, severe myocardial damage can also easily lead to myocardial infarction. The main clinical symptom of patients with myocardial infarction will be pain in the precordial area, and it can not be relieved after rest, and there will be dyspnea, cough and digestive tract symptoms.

The most common causes of death from acute myocardial choking include: cardiac rupture, ventricular aneurysm, mural thrombosis, acute pericarditis, arrhythmias, cardiogenic shock, and myocardial infarction is the blockage of coronary arteries that nourish the heart itself, resulting in a sharp reduction or interruption of blood supply. Myocardial infarction, as a common disease that seriously threatens the health and life of middle-aged and elderly people, is basically coronary atherosclerosis, coronary endothelial dysfunction, hyperlipidemia and other factors can cause continuous spasm of blood vessels and intraluminal thrombosis, resulting in complete occlusion of coronary arteries, causing the myocardium to lose nutrients seriously and for a long time, and necrosis.

In our country, among various heart diseases, rheumatic heart disease is the most common cause of arterial embolism. 2113 With the increase of arteriosclerotic heart disease, the proportion of arterial embolism caused by coronary heart disease is also increasing. After heart valve transplantation and subacute bacterial endocarditis, it is also one of the leading causes of arterial embolism.

Therefore, the heart is the source of arterial embolism.

2.Vascular-dergenic: detachment of arteriosclerotic plaques can be a cause of thrombothrotic 4102 plugging, but it is less common. (Thrombus detachment in deep vein thrombosis of the lower extremities is the main cause of pulmonary embolism.) Described in a later chapter. ）

3.Iatrogenic : With the development of medicine. With the advancement of cardiac and vascular surgery, the development and popularization of various invasive vascular examinations 1653 and interventions**, iatrogenic factors are also increasing, and the fracture of catheters or guidewires can also become emboli.
