What is a cardiac infarction What is a myocardial infarction

What is a heart plug, do you know?

Myocardial infarction should be said to be one of the more common diseases in the elderly, especially in the middle-aged and elderly, more common among men, then myocardial infarction should be said to be a symptom, it is a presternal one, an oppressive pain, including a precordial area, oppressive pain, may be like the left shoulder, left upper limb radiation, then the duration is relatively long, generally more than 10 minutes, the way of relief is general, the way of applying nitroglycerin, the relief is relatively poor, not easy to relieveAt the same time, this kind of pain is generally combined with this, the pressure in the precordial area, some people will have a feeling of impending death, of course, the most serious one of the myocardial infarction is called sudden death type, then this kind of patient, suddenly there is one, respiratory and cardiac arrest, which is a very, very high risk.

Myocardial infarction, also known as myocardial infarction, is a relatively serious heart disease, some patients suffer from coronary atherosclerotic heart disease, if not timed, patients may have coronary artery blockage, resulting in insufficient blood supply, causing myocardial ischemia and necrosis, resulting in myocardial infarction. Patients with myocardial infarction may have severe precordial pain accompanied by chest tightness, palpitation and other symptoms, and if not timely, cardiogenic shock and arrhythmia may occur, which may endanger the patient's life. Therefore, patients with myocardial infarction should go to the hospital in time to improve the relevant examinations, and under the guidance of the doctor, they should be scientifically standardized to promote the disease.

It is the blockage or narrowing of the coronary arteries in the heart, resulting in insufficient blood supply. That is, myocardial ischemia, in severe cases, will stop the myocardium from contracting and relaxing, that is, the heart will stop beating and die.

Myocardial infarction is also known as myocardial infarction. It is due to coronary atherosclerosis, followed by thrombosis, the branches of the coronary arteries are blocked, so that a part of the heart muscle loses blood ** and dies. At the onset of the disease, there are severe and persistent anterior chest pain, palpitations, wheezing, weak pulse, and decreased blood pressure similar to angina.

It is a disease in which coronary artery spasm or thrombosis causes insufficient local blood supply and myocardial necrosis.

Myocardial infarction, also known as myocardial infarction, refers to a disease in which coronary artery blood is interrupted on the basis of coronary artery disease, myocardial acute ischemia, and eventually leads to myocardial avascular necrosis.

In the final analysis, myocardial infarction is a blood disease, myocardial infarction, blood cannot flow to the heart, and sudden death will occur.

Myocardial infarction is a common disease in life, often on the basis of coronary atherosclerotic plaque, there is a rupture of plaque, the formation of blood clots, which leads to the complete occlusion of blood vessels. In the heart, there are generally coronary arteries on the left and coronary arteries on the right.

Myocardial infarction, which is defined as the coronary artery that has been narrowed, if the blood supply to the heart is caused by various reasons, a sudden acute decrease or even interruption, which causes long-lasting ischemia of the myocardium, myocardial necrosis can occur, which is called myocardial infarction or myocardial infarction. It will have more typical manifestations after clinical occurrence, such as persistent pain behind the sternum, accompanied by cold sweat, and then when doing the examination, the electrocardiogram will have a series of specific changes, including the increase of cardiac enzymes in clinical laboratory tests, including many complications that the patient may have, such as arrhythmia, and even cardiogenic shock or heart failure, all a series of manifestations are the causes of myocardial infarction, its clinical symptoms, and the serious complications it may cause.

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.

The heart is a very important organ of the human body, as we all know, the heart beats every minute, and the beating of the heart must rely on the heart muscle cells, and the heart muscle cells need to be supplied by the coronary arteries. Due to the occurrence and development of atherosclerotic plaques in the coronary arteries, if there is narrowing or blockage, or if a thrombus suddenly forms, the myocardial blood supply will be blocked, and myocardial infarction will occur. Myocardial infarction is a manifestation of coronary heart disease and an acute and critical illness in cardiovascular medicine.

After the occurrence of myocardial infarction, there will be severe and compressive pain in the retrosternal or precordial area, and this pain will continue to be unrelieved, and it will be accompanied by various discomforts such as dyspnea, a sense of impending death, and sweating, which must be paid enough attention to. If it is not timely, there will be more serious consequences, complete necrosis of the myocardium, contractile function will be affected, heart failure, cardiogenic shock, it is very easy to lead to sudden death.

It may be that the blood vessels of the heart muscle are embolized. It is the blood vessel that is embolized by the thrombosis.

It's the blood vessels in the heart that are blocked.

In severe myocardial infarction, the main thing in acute attack is to actively take myocardial reperfusion**, usually pay more attention to rest, and pay more attention to light diet. During the recovery period, stent implantation can be taken. Relieves symptoms of ischemia.

Myocardial infarction refers to the avascular necrosis of the myocardium, which is a sharp reduction or interruption of the blood flow of the coronary arteries on the basis of coronary artery lesions, so that the corresponding myocardium has severe and lasting acute ischemia, and eventually leads to avascular necrosis of the myocardium.

The muscles above the heart are necrotic due to a lack of blood**, which relieves the condition of coronary heart disease, and the blood relieves or blocks the blood flow to the coronary arteries. Many people develop severe cardiovascular diseases such as asthma, angina, and weak pulse as they get older. The main thing is to regularly observe the patient's ECG changes, which can be better carried out according to the situation**.

Myocardial infarction, also known as myocardial infarction, refers to myocardial necrosis caused by acute, persistent ischemia and hypoxia (coronary artery insufficiency). Atherosclerotic lesions in coronary arteries lead to narrowing of blood vessels as the main cause, and others include coronary embolism, coronary arteritis, metabolic diseases, etc.

Myocardial infarction, also known as myocardial infarction, or myocardial infarction for short, is pathologically defined as the death of myocardial cells due to prolonged ischemia. The most common symptom is precordial pain, which radiates to the left shoulder and arm, accompanied by sweating, nausea and vomiting.

Acute myocardial infarction (also known as myocardial infarction) refers to the blockage of the main arteries supplying the heart, resulting in myocardial ischemia and necrosis in the area. After a myocardial infarction, remember that time is of the essence and seek medical attention as soon as possible**. Drug thrombolysis** and emergency interventional surgery** are the two major programs of acute myocardial infarction, the former is to use intravenous drugs to open the blocked blood vessels, and the latter is to use surgery to open the blocked blood vessels.

The specific ** plan should be selected according to the doctor's analysis results. However, no matter which plan you choose, you will need to follow the doctor's instructions to cooperate**. After interventional surgery, acute thrombosis caused by stent implantation can be prevented by taking antiplatelet drugs such as aspirin and clopidogrel in combination.

There are both original and generic antiplatelet drugs on the market, and there may be differences between the two in terms of clinical trials, manufacturing processes, excipients and impurities. For example, unlike generic drugs, the original clopidogrel bisulfate uses polymorphic form II (orthorhombic crystal form), which is less hygroscopic and more stable than type I products, and does not require special storage requirements compared to generic drugs.

Myocardial infarction is one of the common causes of death in the elderly. However, there are generally early symptoms before myocardial infarction, such as severe chest pain accompanied by cold sweats, irritability, fear, paleness, etc., which are often early symptoms of myocardial infarction and should be closely observed. To avoid myocardial infarction, it is necessary to know the early symptoms of myocardial infarction.

The symptoms of myocardial infarction are closely related to angina, and the pain of angina pectoris can be used to determine whether it is myocardial infarction. The early symptoms of myocardial infarction are as follows: (1) In the past month, the angina pectoris occurs with progressive aggravation or a sudden severe angina attack.

2) The nature of the original angina pectoris changes (frequency, variety, prolongation of duration), or the trigger is not obvious, and it mostly occurs during quiet rest, and the effect of nitroglycerin is poor. (3) Angina pectoris pain is accompanied by sweating, nausea, vomiting, arrhythmia, hypotension, etc., which is often called the pre-infarct state. (4) The onset of angina pectoris changes from the past exertion to the onset of quiet rest at night, and there is no obvious cause at the time of the attack.

5) When angina is attacked, symptoms of cardiac insufficiency appear or the symptoms of original cardiac insufficiency are aggravated. (6) In the past, he was in good health, but suddenly appeared suffocation, fatigue, palpitation and shortness of breath during exercise, and progressively worsened. At this time, it is necessary to be vigilant, which may be a precursor to myocardial infarction.

7) Middle-aged and elderly patients with sudden acute left heart failure, cardiogenic shock, severe arrhythmia, and cannot be explained by other reasons.

Myocardial infarction is usually related to coronary heart disease, coronary atherosclerotic plaque or thrombosis on this basis, resulting in vascular lumen blockage, myocardial infarction can be divided into various types, active rescue and ** may be improved, after the condition is stabilized should be considered for interventional surgery**.

Most myocardial infarctions are caused by coronary artery disease due to chronic ischemia, but they can also be acute ischemia, resulting in myocardial ischemia and hypoxic infarction.

More than 90% of myocardial infarction is caused by thrombosis on the basis of coronary atherosclerotic lesions, less common in coronary artery spasm, and a few by embolism, inflammation, deformity, etc. Myocardial infarction often occurs due to a number of triggers, including overwork, agitation, hemorrhage, shock, dehydration, surgery, or severe arrhythmias.

Actively ** hypertension, hyperlipidemia, diabetes mellitus, to prevent the occurrence of atherosclerosis and coronary heart disease, coronary heart disease patients can take oral aspirin or dipyridine for a long time to fight platelet accumulation, may have the effect of preventing myocardial infarction. Popularizing knowledge about myocardial infarction, early diagnosis and prompt **, strict monitoring and active comorbidities are the keys to improving prognosis. People who have coronary heart disease angina pectoris or have risk factors for coronary heart disease should try their best to prevent the occurrence of myocardial infarction, and pay attention to the following points in daily life:

1. Never lift heavy items. When lifting heavy objects, it is necessary to bend over and hold your breath, which has a similar impact on the respiratory and circulatory system as if you were straining to hold your breath and stool, and is a common cause of myocardial infarction in elderly coronary heart patients. 2. Relax your spirit, live happily, and be able to deal with everything calmly.

3. Pay special attention to bathing. Do not bathe with a full meal or hunger. The water temperature is best equivalent to the body temperature, and the water temperature is too hot to make the blood vessels expand significantly, and a large amount of blood flows to the body surface, which can cause cardiocerebral ischemia.

The bathing time should not be too long, the bathing room is generally stuffy and not ventilated, in such an environment, people's metabolic level is high, it is easy to lack oxygen, fatigue, especially for elderly coronary heart patients. Patients with more severe coronary heart disease should take a bath with the help of others. 4. Beware of climate change.

Under the influence of severe cold or strong cold air, coronary arteries may spasm and secondary thrombosis can cause acute myocardial infarction. When the climate changes dramatically and the air pressure is low, patients with coronary heart disease will feel significant discomfort. Domestic data show that persistent low temperature, strong wind, and rainy weather are one of the causes of acute myocardial infarction.

Therefore, whenever the climate is bad, patients with coronary heart disease should pay attention to keeping warm or appropriately taking nitroglycerin drugs to protect them.

Here's what experts say (please refer to): myocardial infarction, also known as myocardial infarction, is one of the common critical diseases in internal medicine due to the rapid occurrence of severe and long-lasting ischemia and myocardial death caused by hypoxia in some myocardium. Pathology of myocardial infarction**:

Platelet aggregation: 90% of patients with myocardial infarction have thrombosis proximal to the artery in the infarcted area, often occurring at the rupture or ulceration of atheromatosis. Coronary atheroplaque collapse is seen in 90% to 100% of patients with acute myocardial infarction. Coronary artery spasm can cause stagnation and blockage of blood flow in the coronary arteries, and then damage the coronary intima, causing rupture and bleeding, so that the content of thromboxane A2, which has strong platelet aggregation and vasoconstriction, is relatively increased in the body, causing platelet aggregation and promoting thrombosis.

The blood vessels that supply blood to the heart are called coronary arteries, and the stenosis of blood vessels in the coronary arteries is called coronary heart disease, and the complete blockage of the coronary arteries is called myocardial infarction!

Hello, myocardial infarction is the death of myocardial cells, mostly caused by coronary heart disease, once it occurs, it needs to be thrombolyzed in time**, if it does not occur, it is necessary to control blood pressure, blood lipids, coronary heart disease, traditional Chinese medicine must be taken under the guidance of traditional Chinese medicine, and it is easy to bleed if it is not used well.
