What is coronary heart disease 40

Coronary atherosclerotic heart disease is a heart disease caused by atherosclerotic lesions in the coronary arteries, resulting in narrowing or blockage of the lumen of the blood vessels, resulting in myocardial ischemia, hypoxia or necrosis, and is often called "coronary heart disease".

The World Health Organization divides coronary heart disease into 5 major categories: asymptomatic myocardial ischemia (occult coronary heart disease), angina, myocardial infarction, ischemic heart failure (ischemic heart disease) and sudden death. Clinically, it is often divided into stable coronary artery disease and acute coronary syndrome.

Coronary atherosclerotic heart disease is also referred to as coronary heart disease, and the coronary arteries supply blood to the heart like a hat. The coronary arteries are blood from the thick arteries and gradually transported to the capillaries, giving nutrients to each heart muscle cell in the heart. If the large arteries above are narrowed or blocked, it will cause avascular necrosis of many cardiomyocytes.

When the coronary arteries become narrowed, they can't supply enough oxygenated blood to the heart, especially after strenuous exercise. At first, blood flow is reduced and may not cause any symptoms. However, as plaque in the coronary arteries continues to accumulate, the narrowing of the coronary arteries increases, and eventually the signs and symptoms of coronary heart disease develop.

The most common symptom is chest pain, which can also be accompanied by palpitations, shortness of breath and other related manifestations.

In the early stages, there may be no clinical symptoms, except for an electrocardiogram or exercise treadmill that reveals abnormal ST-T changes. Angina pectoris may also occur during strenuous physical activity or heavy physical activity, which can be relieved by resting or using drugs that dilate the coronary arteries, such as nitroglycerin, for about three minutes. The typical first symptom is chest pain, also known as angina, which is caused by transient narrowing or blockage of the coronary arteries.

Patients may feel a feeling of pressure or tightness in the chest area, as if they were being stepped on on the chest, usually in the middle of the chest or to the left of the chest.

This is followed by compression of the chest, and when the coronary arteries are completely blocked, it triggers a heart attack, which is called acute myocardial infarction. Typical symptoms of a heart attack include signs of pressure in the chest and pain in the shoulders and arms, accompanied by shortness of breath and profuse sweating. Women are more likely than men to have atypical symptoms of a heart attack, such as neck or jaw pain.

There is also shortness of breath, which occurs when the heart is unable to pump enough blood to meet its needs, causing shortness of breath and extreme fatigue.

In addition, there may be some accompanying symptoms, such as toothache, sudden cold sweat, dizziness, nausea, indigestion, or neck pain and shortness of breath during activity. Chronic coronary artery disease, symptoms of angina, anxiety, nervousness, fatigue, neck pain, sleep disturbances and weakness can appear. When combined with arrhythmia, cardiogenic shock, heart failure, stroke, and cardiac arrest, palpitations, palpitations, shortness of breath after exertion, dizziness, syncope, etc., can occur, and serious adverse reactions.

Coronary heart disease, also known as coronary atherosclerotic heart disease, is a type of heart disease, so many people call coronary heart disease heart disease. In fact, there are many types of heart disease. Coronary heart disease is just one type of heart disease.

I think the questioner should be asking about coronary heart disease! What is coronary heart disease? Coronary heart disease is short for coronary heart disease, or coronary atherosclerotic heart disease.

There are five types of coronary heart disease, and the following are the manifestations of each type. 1. Insidious, the patient has no self-conscious symptoms, but the routine resting electrocardiogram shows abnormal ischemic changes. 2. Angina pectoris, which is manifested as paroxysmal precordial pain or discomfort during exertion or tension, mostly compression or contraction or suffocation, often radiating to the left shoulder or left arm, little finger or ring finger, and some people release it to the teeth and upper abdomen to cause toothache or stomach pain.

Lasts 3 to 5 minutes. (rest or sublingual administration, nitroglycerin 1 to 3 minutes after the pain can disappear) 3, myocardial infarction type, manifested as sudden severe pain in the precordial area, lasting more than 30 minutes or several hours, often complicated by severe arrhythmia, heart failure or shock, life-threatening can lead to sudden death. 4. Ischemic cardiomyopathy type, manifested as cardiomegaly and heart failure, severe and intractable arrhythmias, etc., with poor prognosis.

5. Sudden death type, which mostly occurs on the basis of atherosclerosis and myocardial lesions, can occur anytime and anywhere, manifested as sudden collapse, respiratory and cardiac arrest, and loss of consciousness. If effective cardiopulmonary resuscitation is given within 4 to 6 minutes of onset, 5% to 6% of patients will survive. Generally, coronary heart disease is more common in middle-aged and elderly people over 40 years old.

However, with the continuous improvement of living standards, the acceleration of work rhythm, and the intensification of social competition, the incidence of coronary heart disease has been increasing in recent years, so prevention is a top priority. There are many factors for the formation of coronary heart disease, such as high blood pressure, hyperlipidemia, smoking, genetic obesity, diabetes, reduced physical activity, etc. ...The above factors are closely related to us, so how to effectively prevent coronary heart disease should be paid attention to.

Everyone should start from themselves, from the bits and pieces of life, to reduce hair **. For friends who have already suffered from coronary heart disease, we should also be active, and strive to minimize the harm of coronary heart disease. Thank you all and finally wish you good health!

Coronary heart disease is a disease caused by cardiac ischemia caused by narrowing of the heart vessels, that is, coronary arteries due to various reasons, with five major manifestations, including asymptomatic coronary heart disease, angina pectoris, myocardial infarction, heart failure, and sudden death. The manifestations of angina pectoris are more common, especially those related to labor and gravity, which are manifested as chest suffocation, chest tightness, chest pain, chest distention, suffocation, squeezing, and even radiating to the back, especially the left shoulder, left upper arm, and even to the left little finger, some radiating to the pharynx and lower jaw, resulting in tightness of the pharynx, and even extreme toothache, and a few radiating to the upper abdomen, such as the elderly will show stomach pain, which may also be a manifestation of angina.

If the symptoms of angina persist for more than half an hour and are not relieved, or even accompanied by sweating, severe chest pain, and even nausea and vomiting, then myocardial infarction may be combined, and in the case of long-term ischemia, regardless of whether the blood vessel is stenosis or not, after the stent bypass is done or not, the heart will be in a state of long-term ischemia, which may lead to cardiac ischemia, ischemia for a long time, leading to heart failure. Heart failure is manifested as chest tightness, shortness of breath, edema of the lower limbs, and the most serious can lead to arrhythmia, sudden cardiac death, cardiac arrest, which requires emergency rescue, cardiopulmonary resuscitation, defibrillation if necessary.

Hello, the main clinical manifestations of coronary heart disease are angina pectoris, arrhythmia caused by myocardial ischemia and hypoxia, and myocardial infarction can occur in severe cases.

The clinical manifestations are angina pectoris, arrhythmia caused by myocardial ischemia and hypoxia, and myocardial infarction can occur in severe cases. In severe episodes, convulsions can also occur.

Heart palpitations, shortness of breath, angina, etc., my aunt used to have coronary heart disease, my aunt used it.

You can take a look.

Coronary heart disease is a type of heart disease caused by a blockage of a blood vessel in the heart.

Actually, you'd better go to the hospital and check it out!!

You can choose natural**, you can slowly say goodbye to taking medicine! As you know, medicine is three parts poisonous, and long-term medicine will have ***.

Therefore, it is recommended that you choose nature**, for example, you often go to places with many trees to take a walk and absorb more negative ions! If you don't have access to it, you can choose to buy one.

Ionizer air purifier to keep at home! Here we recommend you to use the Centepepyl Ionizer!

If you are not feeling coronary heart disease, go to the hospital for further examination.
