Myocardial infarction symptoms, myocardial infarction, what are the symptoms

Myocardial infarction and angina pectoris are manifestations of coronary heart disease.

Angina pectoris is a clinical syndrome with episodic chest pain or chest discomfort caused by coronary insufficiency, acute, temporary ischemia and hypoxia of myocardium.

A typical attack of angina pectoris is a sudden, squeezing, bulging, or narrowing pain located behind the upper or middle sternal body, and may also affect most of the precordium, radiating to the left shoulder, anteromedial aspect of the left upper extremity, reaching the ring finger and little finger, and occasionally accompanied by a sense of near-death fear, often forcing the patient to stop moving immediately and, in severe cases, sweating. The pain lasts 1 to 5 minutes and rarely exceeds 15 minutes; Rest or tablets containing nitroglycerin, disappear within 1 to 2 minutes (rarely more than 5 minutes). It is often precipitated by physical exertion, emotional agitation (anger, anxiety, overexcitement), cold, full food, smoking, tachycardia, or shock.

Atypical angina, pain may be located in the lower sternum, left precordium, or upper abdomen, radiating to the neck, jaw, left scapula, or right anterior chest, and pain may be rapid or only a feeling of discomfort and tightness in the left anterior chest.

Some people present with toothache, stomach pain, etc.

It is best to go to the hospital as soon as possible for a check-up.

Hello. According to your description, it should not be a myocardial infarction. It may be due to neuralgia or other reasons, so it is recommended that you go to the hospital for a check-up. Wishing you good health.

Myocardial infarction is an emergency and serious disease in cardiovascular medicine, and the occurrence of myocardial infarction is mainly due to the appearance of atherosclerotic plaques in the coronary arteries of the heart, and the formation of blood clots after the atherosclerotic plaques burst. When the coronary artery is blocked by a blood clot, the blood supply is problematic, and the myocardium has no nutrients provided by the blood, resulting in ischemia, and then necrosis, which causes a series of clinical symptoms. Myocardial infarction can manifest as a persistent, severe pain or swelling sensation in the precordial area or the entire anterior chest, accompanied by discomfort such as sweating and palpitations, which can also radiate to the shoulder and back, and even describe some patients as a sense of impending death.

If myocardial necrosis is very severe, malignant arrhythmias or heart failure can occur. Patients may also experience worsening of wheezing or fainting, blackout, etc.

1. The pain appears first, mostly in the early morning, the location and nature of the pain are the same as angina, but the degree is severe, the duration is long, up to several hours or longer, and it cannot be relieved by rest or nitroglycerin.

2. Patients are often irritable, sweating, and fearful, which can be accompanied by a sense of impending death, and a few patients have no pain, and they are in shock or acute heart failure at the beginning. In some patients, the pain is located in the upper abdomen and is easily misdiagnosed.

3. Most of the attacks have no obvious cause, and often occur when they are quiet, the location and nature of the pain are the same as angina, but the pain is more severe, lasts for a long time, up to several hours or even days, and is ineffective with nitroglycerin.

The onset of myocardial infarction varies from symptom to onset, with pain being the most common. Therefore, it is of great significance to understand the different initial symptoms at the onset of the disease and to diagnose and treat the disease in a timely manner.

1) Symptoms begin with sudden syncope. It is common in patients with increased vagus tone in the acute early stage of inferior posterior infarction, and usually occurs within 30 minutes of onset. Patients with severe sinus bradycardia or high-grade atrioventricular block, extremely slow ventricular rate, decreased blood pressure, and sudden syncope.

2) Pain as the starting symptom. About 70% of patients with acute myocardial infarction have pain as the main symptom, and this type of cytoma is more severe and long-lasting than the general angina pectoris.

3) Acute left heart failure is the prominent manifestation. Sudden onset of pulmonary edema is the initial manifestation without warning, and some have prodromal symptoms of angina hours or days ago. Onset of symptoms such as chest tightness, asphyxiating dyspnea, orthopnea, noisy breathing, blister sounds in the lungs, white or pink frothy sputum, sweating, and cyanosis are generally painless or masked by obvious dyspnea.

4) Sudden death as the starting symptom. The onset of the disease is ventricular fibrillation, which manifests as sudden death, which usually occurs outside the hospital.

5) Shock as a prominent symptom of onset. People feel weak, sweat profusely, such as slipping from a sitting position, falling from a standing position, or have a transient loss of consciousness. Cerebral ischemia caused by low cardiac output can lead to death in extreme cases.

In milder cases, cold sweats, dizziness, clammy limbs, pale or gray cyanosis, weak pulse, low systolic blood pressure, and little or no urine.

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.

Breathing is sometimes difficult, usually with retrosternal pain. Pain is more common than early in the morning.

Myocardial infarction occurs with symptoms such as pain, gastrointestinal symptoms, low blood pressure and shock, cardiac asthma, and heart failure. Patients with myocardial infarction can choose to live the brain and nourish the heart**, and control the condition is no longer**!

The main chaotic state refers to food: eat more rice, porridge, noodles, milk, vegetable oil, vegetables, fruits, weak tea, etc.

Now Cushman & Wakefield is good for cardiovascular and cerebrovascular diseases. Shut up and you can search for them**.

The typical symptoms of myocardial infarction should be a pain in the left and middle of the chest, as if being pressed by a heavy object, and the patient will feel that he or she will have difficulty breathing, his heart will beat faster, and he will have a sense of imminent death. However, some patients with myocardial infarction, because the infarction site is close to the apex, and the position of the apex and the upper part of the stomach is very close, often the patients themselves do not know whether it is stomach pain or not, and when they go to the hospital and say that they have stomach pain, they will mislead the doctor's direction. I think that's the case with your uncle.

Myocardial infarction is the cause of death in many middle-aged and elderly people, and the mortality rate is much higher than that of cancer. Because you don't know when it's going to happen or where it's happening. In layman's terms, it means that the blood vessels of the heart are blocked, and the myocardium dies because there is no blood supply, and the necrotic part of the myocardium does not work.

The heart is an organ that pumps blood to the whole body, and if a relatively large area is necrotic, the heart will not be able to pump blood to the whole body, and other organs will die of lack of blood and oxygen. Brain hypoxia can cause irreversible brain death after 5 minutes of hypoxia, so myocardial infarction is a very urgent disease.

Myocardial infarction varies according to the size of the infarction. If it is a small vessel infarction, the patient has a better chance of survival, and if it is a large vessel infarction, the patient has a high probability of death. In addition, many family members are panicked and busy when the patient is sick, and they don't know whether they should let the patient lie down and rest, so they quickly give the patient oxygen, and then dial 120, and cannot move the patient without permission, which causes the delay of myocardial infarction patients in the early stage of the disease.

In addition, it should be reminded that the onset of myocardial infarction is sometimes manifested by toothache and numbness in the left limb, and not every patient will feel heart pain.

Acute myocardial infarction is a severe type of coronary heart disease caused by local necrosis caused by acute occlusion of coronary arteries, resulting in acute ischemia of the corresponding myocardium.

Some patients develop symptoms such as fatigue, heartache or chest discomfort, palpitations during activity, shortness of breath, irritability, and angina pectoris a few weeks before the onset of the disease.

Pain is the first symptom to appear, and its location and nature are similar to angina, but the degree is more intense, and it is often unbearable squeezing, suffocation, and even "impending death". Accompanied by profuse sweating and irritability. or generalized fever, tachycardia, elevated white blood cells, and increased erythrocyte sedimentation rate.

It may be accompanied by frequent nausea, vomiting, epigastric pain, intestinal flatulence, etc.

If there is a sudden crushing pain in the precordial area, which lasts for 20 minutes, it may be accompanied by profuse sweating, paleness, nausea and vomiting, which may be a myocardial infarction, in addition to shoulder and back pain, pain in the left arm and left shoulder, and sometimes radiating to the lower jaw teeth.
