What is coronary heart disease? What s going on with coronary heart disease

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.

If you say it carefully, you can take a look.

Why do some patients with coronary heart disease die at the age of 40, while others live to the age of 90? Coronary heart disease is simply a heart disease caused by cardiovascular stenosis caused by excessive blood vessels in the heart arteries, resulting in coronary atherosclerosis. For patients with coronary heart disease, if the best is appropriate, some patients can have the same life expectancy as a normal person, unhealthy diet, stay up late and be stressed, or have three highs that are not found, and there are three highs that are not controlled, then the possibility of coronary heart disease is earlier than others.

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". However, coronary artery disease may be broader and include inflammation, embolism, etc., leading to lumen narrowing or occlusion. The World Health Organization divides coronary heart disease into 5 categories:

There are five clinical types: asymptomatic myocardial ischemia (occult coronary heart disease), colic, myocardial infarction, ischemic heart failure (ischemic heart disease) and sudden death. Clinically, it is often divided into stable coronary heart disease and cautious acute coronary syndrome.

Coronary heart disease, short for coronary atherosclerotic heart disease, is a kind of heart disease caused by myocardial ischemia and hypoxia or myocardial necrosis caused by organic stenosis or blockage of coronary arteries, and is also a common cardiovascular disease. The common methods of coronary heart disease in Changqin include drugs, intervention, and heart bypass. Cardiac stents are commonly used in intervention, and now there is a new generation of degradable stents that are resistant to carrying bi, which will be listed in 2019 in China, and it is called a bioresorbable stent by Lepu.

It is basically degraded about 3 years after implantation, and will not remain in the body permanently like traditional metal stents.

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 1-3 minutes after Lu Chong 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 suffered from coronary heart disease, they 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 the abbreviation of coronary atherosclerosis heart disease, which is a type of heart disease. At present, the common methods include drugs, interventional surgery and heart bypass. Now there is a new type of degradable stent for cardiac stents, which will be listed in 2019 in China, which is Lepu's, called bioresorbable stents.

It is fully degraded about 3 years after implantation, unlike the traditional metal stent, which is permanently placed in the body, and the blood vessels also return to normal. However, which method is suitable for you, you need to go to the hospital for a detailed examination before choosing. In addition, we should try to develop good living habits as much as possible.

Cardiovascular diseases such as coronary heart disease are common diseases in the elderly, and when the condition is severe, there is a high risk of sudden death. Nowadays, coronary heart disease is more common in people, and young people are also likely to suffer from coronary heart disease. If you suffer from coronary heart disease, you not only need to be active, but also need to do a good job of daily care and care.

So do you know about coronary heart disease?

1. It is related to age

The main population of coronary heart disease is middle-aged and elderly people over 40 years old, and the progress is faster after the age of 49, but in recent years, the incidence of coronary heart disease has a trend of younger people.

2. It is related to gender

After menopause in women, due to the significant decline in estrogen levels, the incidence of coronary heart disease has a clear upward trend, and there is a correlation that shows that there are more women than men after 60, and in the United States, the mortality rate of coronary heart disease in men is significantly higher than that of women, and in China, the ratio of men to women is about 2 1.

3. Career-related

Mental workers are generally more than manual workers because they are in a sense of oppression for a long time.

4. It is related to diet

If we consume high-calorie, high-fat, and high-cholesterol foods for a long time, there are many harms to the body, and these foods will cause excess lipids to be deposited in the arteries and blood vessels, which will cause arterial stenosis and hardening.

5. It is related to obesity

Obese people with excess standard weight, especially those who gain weight rapidly, are susceptible to coronary heart disease, can not only look at the body mass index, should pay attention to the study of the method of evaluating weight, but should measure the thickness of subcutaneous fat, there have been prospective research data show that centripetal obesity has a greater risk.

6. Related to blood pressure

Although hypertension is not the main cause of cerebrovascular and coronary heart disease, it can aggravate the hardening of arteries and blood vessels, so if the blood pressure exceeds the standard for a long time, it is necessary to take medication to lower blood pressure. In addition to sleep and environmental factors, hypertension is caused by blood fats invading the lining of blood vessels, resulting in hardening of the arteries, which is one of the causes of death from hypertension.

7. Related to smoking

According to the survey, smoking is the main risk factor for coronary heart disease, and the morbidity and mortality rate of smokers are two to six times higher than that of non-smokers, and are proportional to the number of cigarettes smoked per day.

8. It is related to blood lipids

Dyslipidemia due to genetic factors, or excessive fat intake, or lipid metabolism disorders. If total cholesterol, triglycerides, LDL, and VLDL are increased, and HDL is decreased, the disease is susceptible.

There are many more causes of coronary heart disease, and the above list of eight points, the harm caused by this disease to patients is very large, so it is quite necessary to do a good job of prevention.

Coronary heart disease is commonly known as a blockage of blood vessels supplying the heart. If it is blocked, there is a strong blockage, not a bad one, if it is very light, you can take medicine, but also pay attention to the diet, slightly more serious, to put a heart stent, simply put, the blocked blood vessels are opened, the blood vessels are supported, and if it is very serious, a heart bypass will be performed.

First of all, how old are you, middle-aged people are generally not too serious, and the probability of bypassing is not particularly high.

Pay attention to your diet, pay attention to cholesterol intake, etc., and do not eat squid, caviar, egg yolk, and other high-cholesterol things. It is estimated that you are not seventy or eighty years old, and it is estimated that it will not be too serious.

We mentioned coronary heart disease, first of all, let's learn what coronary heart disease is. Our coronary heart disease is actually coronary atherosclerotic heart disease, so you see I have a model of the heart on my right, so what is coronary artery? In fact, this coronary artery runs on the surface of the myocardium, and this coronary artery provides nutrients and energy to the myocardium, so our coronary heart disease is due to some narrowing of the blood vessels caused by atherosclerosis in the coronary arteries, and some myocardium will appear after narrowing.

Then we investigate the mechanism of coronary heart disease, the main one is the stenosis of a coronary artery, which is formed by plaque, so we actually investigate how the plaque is formed. The formation of plaque is clearly related to four major risk factors, first, we just talked about hypertension, hyperlipidemia, and people with particularly high blood sugar, diabetic patients, and smoking, which are all important risk factors for the formation of atherosclerotic plaque.

Therefore, when we want to prevent coronary heart disease, we must control blood pressure, blood sugar, blood lipids, and quit smoking scientifically, which can be a good control and prevention of coronary heart disease.

Hypertension is an important independent risk factor for the absence of coronary heart disease Beijing Coronary Heart Disease Prevention and Control Group 1972 Among the patients with acute myocardial infarction admitted in 1991, a history of hypertension was present. The prevalence of hypertension increases with age, especially systolic hypertension. Coronary heart disease events occur more frequently in elderly patients with systolic hypertension.

Elevated blood pressure is usually accompanied by hyperlipidemia, hyperglycemia, and elevated fibrinogen. These increase the risk of coronary heart disease. Diabetes mellitus is another risk factor for coronary heart disease that increases with age, and 8% of acute myocardial infarction cases with a history of diabetes mellitus admitted to the Beijing Coronary Heart Disease Prevention and Control Cooperative Group are also on the rise.

The risk factors and clinical course of coronary heart disease in women are different from those in men The prevalence of coronary heart disease in women increases after menopause, and the incidence of coronary heart disease in postmenopausal women is three times that of non-menopausal women. In 1995, the American College of Cardiology reported that estrogen can prevent the coronary arteries from contracting in women, but not in men. Increased coronary heart disease in older women is associated with longer life expectancy and changes in estrogen secretion.

Guidance: It is recommended not to eat tobacco and alcohol, and to eat greasy food. and Chinese patent medicine that lowers blood lipids, exercises regularly and promotes blood circulation and dispels blood stasis**.

Heartache is generally a pain in the stomach, mostly stomach cramps, and some are stomach ulcer attacks; Especially for people with high blood pressure and coronary heart disease, don't forget gastrointestinal angina; There is also a type of cold called abdominal cold, which also causes pain in the upper abdomen, sometimes similar to gastroenteritis

Risk factors and precipitating risk factors for coronary heart disease include modifiable and non-modifiable risk factors. Understanding and intervening in risk factors can help prevent and treat coronary heart disease. Modifiable risk factors are:

Hypertension, dyslipidemia (high total cholesterol or low density lipoprotein cholesterol, high triglycerides, low high-density lipoprotein cholesterol), overweight Obesity, hyperglycemia Diabetes, unhealthy lifestyle including smoking, unreasonable diet (high fat, high cholesterol, high calories, etc.), physical inactivity, excessive alcohol consumption, and psychosocial factors. Non-modifiable risk factors include gender, age, and family history.

In addition, it has been associated with infections such as cytomegalovirus, Chlamydia pneumoniae, Helicobacter pylori, etc. The onset of coronary heart disease is often associated with seasonal changes, emotional agitation, increased physical activity, satiety, heavy smoking, and alcohol consumption. Coronary heart disease** includes:

Changes in lifestyle habits: quitting smoking and limiting alcohol, low-fat and low-salt diet, appropriate physical exercise, weight control, etc.; Drugs**: antithrombotic (antiplatelet, anticoagulant), reduce myocardial oxygen consumption (receptor blockers), relieve angina pectoris (nitrates), regulate lipids and stabilize plaques (statins); Revascularization**:

These include interventional** (endovascular balloon dilation plasty and stenting) and surgical coronary artery bypass grafting. Drugs are the basis of all. Long-term standard medications** are also adhered to after interventional and surgical procedures**.

For the same patient, drugs can be ideally controlled at one stage of the disease, while drugs alone** are often less effective at another stage, requiring a combination of drugs with interventional** or surgical procedures. It is recommended that the subject consult a cardiologist.
