Do you know what coronary heart disease is? How is coronary heart disease caused?

With the development of modern economy and the improvement of people's living standards, the incidence of coronary heart disease is also increasing, and it has become one of the main killers of human health. Coronary heart disease is a common name for coronary atherosclerotic heart disease, and its basic lesion is the thickening of the intima of the coronary arteries that supply blood oxygen to the heart, fat deposition and atherosclerosis, resulting in narrowing of the lumen of the arteries, affecting myocardial blood oxygen**, and producing a series of cardiac changes, such as angina, arrhythmia, heart failure, myocardial infarction, etc. What are the causes of coronary heart disease?

Due to the relationship between work and life, it is common for modern people to stay up late. And staying up late means not getting enough sleep. Long-term lack of sleep will not only affect people's mental condition, but also lead to long-term lack of blood oxygen supply, blood vessel constriction, and in the long run, it will naturally damage blood vessels and heart, and eventually lead to the appearance of coronary heart disease.

People with consistently high blood pressure are also more likely to develop atherosclerosis, because the vascular endothelial cells in hypertensive patients are more likely to be damaged by friction due to blood flow. The pressure in the blood vessels makes it easier for fat to enter the inner walls of the arteries. Blood clots form or cause abnormal growth of the smooth muscles lining the blood vessels, making it more likely to lead to coronary heart disease.

At present, social diet is the most important factor in inducing chronic diseases, eating high-calorie foods and foods with high cholesterol for a long time will make the blood thicker and have too many blood impurities, so that the blood flow rate will slow down, and the probability of coronary artery blood vessels forming plaque will increase, and once the plaque ruptures, it will form thrombosis, causing myocardial infarction, so diet is also the main cause of coronary heart disease.

Smoking has damage to the respiratory system, and at the same time the adverse effects on the human vascular system are also relatively large, from the clinical observation of the situation, after smoking, the probability of myocardial ischemia and hypoxia is much higher, and if young people like to smoke, then it is easy to have arrhythmia, the risk of sudden death will also increase.

Coronary heart disease is the heart disease caused by atherosclerosis of the large blood vessels of the heart, also known as coronary arteries, resulting in narrowing or blockage of the lumen of the blood vessels, or because of the spasm of the coronary arteries, resulting in ischemia, hypoxia or necrosis of the myocardium, which is called coronary heart disease, and can also be called ischemic heart disease. The main cause of coronary heart disease is atherosclerosis leading to vascular lesions, the first of atherosclerosis is not completely certain, but it has related risk factors are relatively clear, such as age, gender, which mostly occurs in middle-aged and elderly people over 40 years old, especially the incidence is higher in men than women, and the incidence of women will generally increase after menopause. In addition, dyslipidemia is also an important risk factor, cholesterol, triglycerides, especially low-density lipoprotein, high blood pressure, and smoking are also risk factors for coronary heart disease.

There are also diabetic patients, people with impaired glucose tolerance, obese people, mental workers, people with less activity, as well as genetic factors and personality factors, which will affect the occurrence of coronary heart disease.

Coronary heart disease is a kind of heart disease, which will have a serious impact on the body, and there will be angina, myocardial infarction or other diseases when the disease occurs, mainly because of the dilation of blood vessels, the lack of blood, and will have a serious impact on the body, of course, it may also be caused by abnormal fat metabolism.

I know that coronary heart disease is a cardiovascular and cerebrovascular disease, and coronary heart disease is caused by the damage to the protective layer inside the blood vessels, causing qualitative changes in the blood vessels.

First of all, people must not smoke in their daily life, because smoking is the most common risk factor for coronary heart disease, because tobacco contains carbon monoxide and tar, which will damage people's arterial endothelium, so it will accelerate the occurrence of coronary heart disease, and if people themselves suffer from the three highs, they must have regular physical examinations. There are many genetic factors, so it is recommended that young people who are now involved in life should be screened for risk factors as soon as possible.

There are many high-risk factors for coronary heart disease, such as hypertension is its first high-risk factor, and diabetes, diabetic people are more likely to get coronary heart disease, and then there is hyperlipidemia, blood lipids are too high, especially cholesterol is too high It is also easy to cause coronary heart disease, and then smoking, and then sedentary, not exercising, and overweight. In addition, it is important to have a family history of early onset of coronary heart disease, and it is also important to have early onset of coronary heart disease in first-degree relatives. Gender that cannot be changed, for example, men are more likely to have more sex than women.

Then there is age, men are easy to get hair when they are over 56 years old, and women are easy to get hair when they are over 65 years old, so after men and women reach this age, it is also a risk factor for it.

There are many causes of coronary heart disease, and the reasons are coronary atherosclerosis, high blood pressure, high blood lipids, high blood sugar, high age, and high weight are all predisposing factors for coronary heart disease.

Smoking not only causes lung tumors, smoking is also an important and dangerous cause of coronary heart disease, and it is also the single most avoidable cause of death, and there is a clear relationship between coronary heart disease and smoking.

Coronary heart disease is the result of a combination of predisposing factors, including genetic factors, environmental factors, smoking, alcohol consumption, staying up late, high blood pressure, hyperlipidemia, high blood sugar, emotional stress, and anxiety.

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 include hypertension, dyslipidemia (high total or low density lipoprotein cholesterol, high triglycerides, low high-density lipoprotein cholesterol), overweight Obesity, high blood glucose 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 are:

Gender, age, 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.

Chest tightness and shortness of breath, coughing, sternum pain, palpitation, fatigue, and nausea may occur. It is mainly because of irregular living habits, or irregular eating habits, and frequent sulking, which will lead to coronary heart disease.

The precursor of coronary heart disease is that there will be heartache, mental tension, pain in the sternum, and a feeling of suffocation in the chest, which is the precursor of coronary heart disease. It is because of my irregular life and rest, and my mental pressure is relatively nervous.

Symptoms are chest tightness, shortness of breath, lack of oxygen to the brain, chest pain, fatigue, cough, and possibly fainting. Coronary heart disease is usually caused by insufficient blood supply to the heart, or some problems in the heart.

1. Coronary heart disease is the abbreviation of coronary atherosclerotic heart disease, which is a heart disease caused by atherosclerotic lesions in coronary arteries, which causes narrowing or blockage of the lumen of the blood vessels, resulting in myocardial ischemia, hypoxia or necrosis, and we are often called coronary heart disease. In general, the clinic is often divided into five categories, asymptomatic myocardial ischemia, angina, myocardial infarction, and ischemic heart failure and sudden death.

2. Some patients with coronary heart disease have asymptomatic myocardial ischemia, and many patients may not have obvious symptoms of angina. Some patients may present with angina, which typically consists of a squeezing pain in the anterior chest, or tightness and shortness of breath, mainly behind the sternum, or it can radiate to the precordial area, as well as the left upper extremity, and the left back. It mostly occurs under common triggers such as exertion, emotional agitation, satiety, and cold.

If it is a patient with angina, it usually lasts less than 30 minutes, and it can be relieved by rest or nitroglycerin. In some patients, if a myocardial infarction occurs, the pain may be of the same location, but the nature and duration of the pain will increase significantly, and nitroglycerin is not effective.

3. The examination items of coronary heart disease include electrocardiogram, ordinary electrocardiogram, ambulatory electrocardiogram, cardiac color ultrasound, cardiac enzymes, troponin, coronary CTA, and color ultrasound of the cervical vertebral artery to evaluate the risk factors of the congratulatory letter, to evaluate the general condition of the whole body blood vessels, as well as the angiography of our coronary arteries, which directly look at the specific stenosis of the blood vessels.

4. The treatment of coronary heart disease in the elderly mainly needs to pay attention to the following points.

First, the propaganda should be strengthened to inform patients of the definition of coronary heart disease and its risk factors. Advise them to control their diet, low-salt, low-fat, diabetic diet, exercise appropriately, and avoid emotional agitation, dry stools and other triggers.

2. Be sure to take antiplatelet drugs and lipid-regulating drugs regularly. At the same time, if there are risk factors such as hypertension, diabetes, and hyperlipidemia, they should be actively controlled to achieve the goal. If there are bad habits such as smoking, they should be actively corrected.

3. For patients who need to actively clarify the coronary artery condition, coronary angiography should be performed, and if necessary, PCI surgery or coronary artery bypass grafting should be performed.

Mild coronary heart disease may have no symptoms, and as the disease progresses, it is easy to have palpitation, shortness of breath, chest tightness, and chest pain. Coronary heart disease is prone to the symptoms of angina, the patient presents with sudden chest pain, the pain is easy to radiate pain to other parts, easy to radiate pain to the left arm, left shoulder, the pain time is relatively short, generally lasting 1-5min.

Symptoms caused by coronary heart disease are: chest pain, i.e., angina, accompanied by a feeling of squeezing, sweating, lasting more than 3 to 5 minutes; Sudden precordial pain induced by physical exertion or emotional agitation is generally episodic colic, but it can also be felt as suffocation; epigastric pain; tightness in the chest or feeling unwell; a tightness in the throat; Irregular heart rhythm, fast or slow heart rate; Sometimes it is accompanied by sweating, nausea and vomiting.

The most common symptoms of coronary heart disease are angina pectoris, heart pain, sometimes patients feel chest tightness, breathlessness, shortness of breath, severe to the pain, chest pain through the back, back pain through the heart, the whole chest and back will have a painful feeling, even radiating to the shoulders, arms, fingers, and sometimes radiating to toothache.

Common typical symptoms of coronary heart disease: chest pain, pins and needles, dyspnea, back pain, chest pain. Rare symptoms: toothache, headache, dizziness, sudden loss of vision, hearing loss. Abdominal pain, soreness, numbness and pain in the lower limbs, pins and needles on the soles of the feet.

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!
