First, will coronary heart disease affect life expectancy?
Will affect life! I can tell you for sure. Coronary heart disease itself, like age, is an unavoidable problem. Because the basis of coronary heart disease is atherosclerosis, and the process of atherosclerosis has been quietly going on in our bodies since we were born. Someone once said that if atherosclerosis can be cured, our life span can be increased to 200 years, which shows how much influence atherosclerosis has on us! Among the causes of death among China residents, stroke ranks first, and ischemic heart disease, namely coronary heart disease, ranks second. It can be seen that coronary heart disease will definitely affect our life span.
Second, will patients with coronary heart disease live longer?
Sure! Many people will say that what you said is inconsistent? One minute will affect life span, and the next minute will also prolong life span. In fact, coronary heart disease will indeed shorten our life span, but as long as we treat and treat coronary heart disease reasonably, correctly and scientifically, we can live with the disease, live a full life and live beyond the average life span. After all, the disease we need to deal with in this life is not only coronary heart disease, but we may also have to fight other diseases, but simple coronary heart disease can live longer after proper treatment.
3. How will coronary heart disease affect us?
In what ways will coronary heart disease affect our life span? The most common coronary heart disease will affect our quality of life, because after suffering from coronary heart disease, it will lead to a decline in our activity tolerance. However, if coronary heart disease continues to develop, acute cardiovascular events, such as myocardial infarction, malignant arrhythmia and heart failure, can lead to sudden death in severe cases. These are the main events that coronary heart disease affects us.
Remember last week's rescue of post-80s myocardial infarction? There was no rescue. At that time, parents, wives and children were crying ...
Sadly, this patient is less than 40 years old, that is, some coronary heart diseases will die before 40 years old.
So will people with coronary heart disease live short?
Of course not, because we always meet grandparents in their eighties and nineties who also have coronary heart disease in the hospital, but coronary heart disease has not affected the life span of these grandparents.
Then why do some patients with coronary heart disease die in their thirties, and some are still fine in their eighties and nineties?
First of all, the onset age determines the outcome.
Think of a man with coronary heart disease in his thirties and a man with coronary heart disease in his seventies. Can his life span be the same?
Then why do some people get coronary heart disease at the age of 30, and some people get coronary heart disease at the age of 70? On the one hand, it is related to heredity, on the other hand, it is related to our lifestyle, or more importantly, it is closely related to our lifestyle.
Simply put, coronary heart disease is a heart disease caused by coronary atherosclerosis due to excessive vascular garbage in the heart arteries. Research shows that most of us have atherosclerosis since adolescence, but if we have a history of genetic diseases or an unhealthy lifestyle, it will aggravate and accelerate atherosclerosis, thus causing coronary heart disease. If we all live to the age where we won't die of other diseases or accidents, most people's heart arteries and blood vessels may have plaques to some extent. The main factor that determines how often we will get coronary heart disease is lifestyle.
If a person smokes and drinks for a long time, does not exercise for a long time, is obese, has an unhealthy diet, is stressed by staying up late, or has three highs that are not found and controlled, then this person is more likely to get coronary heart disease than others. And if a person can live a healthy life, have a healthy mind and have no bad habits, then the possibility of getting coronary heart disease is small and much later.
Second, attitude determines the result.
The above onset age has actually proved that people with a good attitude towards life have not only a low risk of coronary heart disease, but also an older onset age. This is the first attitude.
The second attitude is to treat the "three highs" and actively and formally control the "three highs", which is naturally far from coronary heart disease.
The third attitude is how to deal with coronary heart disease. Patients with coronary heart disease, especially those with angina pectoris or myocardial infarction, must seize the time and actively treat them. Otherwise, once a heart attack occurs, life will be in danger in an instant. If angina pectoris of coronary heart disease can be treated regularly, the incidence of myocardial infarction can be significantly reduced.
Once a myocardial infarction occurs, we must race against time, seize the time to rescue, do not delay, myocardial infarction will die at any time, and some will have heart failure, which will obviously shorten the life span. Only by opening blood vessels quickly can we save more lives and reduce the occurrence of heart failure.
In the final analysis, preventing coronary heart disease is the key and foundation!
Got coronary heart disease should be actively and formally treated!
Only with regular treatment, coronary heart disease will not affect our life span!

Professional doctors will answer your questions.
This question is somewhat similar to "Can people live forever?" . Immortality is just a beautiful dream, which is impossible to realize. The same is true for people with coronary heart disease, who can enjoy life expectancy like normal people. What is there to regret about such a result? I am worried because I don't know enough about coronary heart disease.
What is coronary heart disease?
The full name of coronary heart disease is the abbreviation of coronary atherosclerotic heart disease. From the name, we know that the pathological basis is the pathological changes of heart and blood vessels. This lesion changed the original structure of blood vessels, because a large amount of fat was deposited under the blood vessels and an inflammatory reaction occurred. Fatty degeneration forms a weak lipid substance, just like a "filler" between the inner and outer layers of blood vessels.
Such blood vessels will thicken, the lumen of blood vessels will narrow, the original good elasticity will no longer have good contraction performance because of "foreign bodies", the blood flow can not expand well to increase space, and the excessive blood flow will be reduced accordingly. Blood is the carrier of oxygen and nutrition for myocardial cells. Without blood flow, oxygen and nutrition will be less, just as people will be hungry if they don't have enough to eat, and myocardial cells will be affected and can't function normally if they are malnourished.
What are the manifestations of coronary heart disease?
The main function of the heart is to provide power for blood circulation throughout the body. When myocardial cells are deprived of oxygen, the contraction function cannot be fully exerted, and the power provided for blood flow is insufficient. Accordingly, the normal function of tissues and organs of the whole body may be affected by oxygen, so there will be palpitation, shortness of breath, dizziness, fatigue and other manifestations.
In a quiet state, people's physiological activities are relatively "low-key and stable", and the demand for oxygen is not great. Therefore, people with coronary heart disease at this time, although the power of blood output is insufficient due to the decline of heart function, will not cause serious hypoxia in tissues and organs, so the symptoms of unsuitability are not obvious. If the physical activity momentum increases and the energy consumption increases, the amount of hypoxia will increase, and all kinds of discomfort will be aggravated, especially in myocardial cells, and angina pectoris will occur.
How big is the influence of coronary heart disease on life?
From the above explanation, we can know that people with coronary heart disease will have insufficient oxygen supply when their physical activity increases. Therefore, in daily life, we should pay attention to avoid fatigue and strenuous activities, maintain emotional stability and peace of mind, and avoid serious hypoxia events caused by increasing the burden on the heart.
The most important thing is to change bad living habits, such as limiting salt and oil, proper exercise, quitting smoking and alcohol, staying up late, etc., actively treat diabetes, hypertension, hyperlipidemia and other risk factors leading to atherosclerosis, prevent and delay the progress of coronary artery disease, and minimize the impact on daily life.
How big is the influence of coronary heart disease on life span?
Coronary heart disease is only coronary artery stenosis caused by atherosclerosis or plaque, and the blood flow will be blocked and reduced, but it will not completely block the blood vessels. Even if angina pectoris occurs, it will only lead to hypoxia rather than anoxia of myocardial cells, so it will not lead to myocardial cell necrosis, and of course it will not be fatal. What can be fatal is another serious heart disease-myocardial infarction rather than coronary heart disease.
So coronary heart disease is not fatal. As long as we take active measures to control it, we can live like normal people. On the contrary, the condition of coronary heart disease can continue to progress, and there is a risk of sudden death caused by myocardial infarction. This reminds people with coronary heart disease that they must follow the doctor's advice and never be careless and bring regret to themselves.
Can people with coronary heart disease live short?
It's hard to say, it depends on the specific situation, and there is no definite answer. We need to know what coronary heart disease is. How is coronary heart disease formed? How to prevent and mitigate?
1. What is coronary heart disease?
In fact, coronary heart disease is not a disease, but a general term for a class of diseases. Coronary heart disease refers to coronary atherosclerotic heart disease, including asymptomatic myocardial ischemia, angina pectoris, myocardial infarction, heart failure and sudden death. Coronary heart disease may be one of the above heart diseases, or there may be several heart diseases.
Second, what factors can lead to coronary heart disease?
Coronary heart disease, the full name of coronary atherosclerotic heart disease, can literally know that this disease is related to coronary artery. Coronary artery is an arterial blood vessel that supplies blood to the heart, providing energy and oxygen for the normal beating of the heart and maintaining the normal operation of myocardial cells. If the coronary artery becomes narrow, occluded or hardened for some reason, then the coronary artery can not provide enough blood to the heart, and the myocardium will be deprived of oxygen, which will lead to myocardial infarction, angina pectoris and other diseases.
These are the direct causes of coronary heart disease, so which one will lead to coronary artery stenosis, occlusion or sclerosis? Many factors may lead to coronary artery problems, such as hypertension, hyperglycemia, hyperlipidemia, obesity, overweight and so on. There are also some unhealthy lifestyles and diets that lead to coronary heart disease, such as long-term smoking, eating heavy-flavored things, not exercising, drinking a lot for a long time, and eating greasy things. There are also some factors that may lead to coronary heart disease, such as bacterial or viral infection, psychological stress, age, heredity and so on. Most of these factors are uncontrollable and account for a small proportion of the factors leading to coronary heart disease.
Third, how to prevent and alleviate coronary heart disease?
Knowing the cause of coronary heart disease, the way to treat and relieve coronary heart disease is to remove or reduce the influence of the above factors. The first is to actively treat dangerous diseases that can lead to coronary heart disease, such as hypertension, hyperlipidemia and hyperglycemia. If these risk factors are controlled, coronary heart disease will be alleviated. Coronary artery stenosis or occlusion is caused by intravascular thrombosis, so it is very important to carry out thrombolytic therapy for blood vessels. For example, aspirin commonly used in patients with coronary heart disease is a thrombolytic drug, which needs to be taken for a long time and for life.
Conclusion: Generally speaking, the life span of patients with coronary heart disease is related to the length and severity of coronary heart disease, whether there are other basic diseases, whether they have received standardized treatment and other factors. Due to timely standardized treatment, some patients with coronary heart disease usually take active exercise and adopt a reasonable diet, which has stabilized the development of coronary heart disease and their life expectancy is not necessarily less than that of ordinary people. Therefore, if patients with coronary heart disease want to prolong their life, they must actively control the pathogenic factors, delay or organize atherosclerosis, and improve their health.
It is not short-lived, but it does have an impact on the length of life.
Coronary heart disease is a disease, as long as it is a disease, it will definitely affect health and damage the body!
I think everyone should know what a disease is, so I won't go into details.
Coronary heart disease is the most common heart disease. Because of its long-term incurable characteristics, the number of patients has increased year by year. According to the patient's age and illness, everyone's risk is different. Some people may die suddenly, while others may live to be 7 or 80 years old. This is not absolute.
Moreover, the length of life is impossible to achieve, and it is impossible for us to predict our specific time of death. So from this point of view, it is absolutely nonsense that coronary heart disease will lead to short life, but the pathogenesis of coronary heart disease lies in the blockage of blood vessels. This kind of blockage will not directly harm our health, but with the aggravation of blockage, the whole body flow of blood will be affected. Once the normal consumption of our heart is not satisfied, it will affect all major organs. When they have problems, the overall function of patients will begin to decline. As our health deteriorates day by day, our life expectancy will naturally decrease, which is a vicious circle.
Heart failure is the most common stage of coronary heart disease. At this point, the patient's heart function has been damaged. Don't talk about the daily impact on patients, just talk about the state and harm. Heart failure is the last stage of the heart, which is difficult to reverse. From the big data, even if it is mild, such patients will become more and more serious over time, and the mortality rate will be above 50% within five years.
Why do some people live a long life?
For those who have such doubts, one should ask: "How do you know that this person can only live to 100 years old?"
This kind of doubt actually has no meaning. The decision of everything needs to be compared. We don't know the patient's initial life span. Naturally, we can't calculate how much coronary heart disease has reduced or even increased it. Just like many people asked me before: Why do many smokers live to be 70, 80 or even hundreds of years old?
Besides the disease itself, there are other factors that will affect the life cycle of patients!
The most typical symptom of patients with coronary heart disease is chest pain, which may not be obvious at first, but with the aggravation of coronary artery stenosis, it will only get worse and worse, which will seriously affect the normal life and work of patients and make patients worry and think all the time. Daily anxiety and depression are also diseases, which will not only affect the quality of life, but also affect the length of life.
The helplessness of modern medicine, medication control+stent first aid!
Coronary heart disease is a chronic disease, because its onset cycle is very long. At present, there is no absolutely effective treatment. Patients often need to take medicine regularly and control their diet. But with the passage of time, stents or bridges are needed to quickly open the blood supply, otherwise it is likely to be dangerous. However, these strategies cannot completely eradicate coronary heart disease. In a sense, the patient's condition has not improved, but the symptoms will be temporarily alleviated or disappeared. If he is unlucky and doesn't take medicine regularly, it is likely to be in a short time.
From the etiology, the pathogenic factors of patients with coronary heart disease are different, so it is necessary to distinguish the focus of treatment, so that some avoidable patients with coronary heart disease can be treated and recovered!
These patients have a certain degree of "moisture" in coronary artery stenosis, and may have undergone angiography, but this result is still insufficient. Let me explain something to you.
Everyone should wear sweaters and buy sweaters according to their figure. Under the condition that their figure has not changed, they are getting tighter and tighter because of the increase of washing times, which is very similar to the cause of coronary heart disease that I will talk about below. If we regard sweaters as blood vessels, then our bodies are plaque thrombosis. If our bodies haven't changed, why are sweaters getting tighter and tighter?
There is only one answer: "The sweater has shrunk."
So do patients with coronary heart disease. We know that the diagnosis and severity of coronary heart disease are directly related to the degree of stenosis. If the volume of plaque thrombus remains unchanged, the proportion of plaque thrombus in different spaces will be different. The plaque thrombosis of these special patients is not much, and the degree of arteriosclerosis is not high, mainly because the blood vessels contract and the official cavity becomes smaller, which will naturally reduce the blood flow and cause the illusion of high stenosis. This patient's plaque stenosis is not high.
Patients with coronary heart disease will not be short-lived, but the premise is to adjust their diet, take medicine regularly and treat them in time, and as long as they are sick, their life expectancy will definitely be affected. So I suggest that some patients with coronary heart disease can recover by finding the cause in time.
There is no absolute relationship between people with coronary heart disease and life span.
So why do some people die of coronary heart disease in their thirties and forties, and some people also suffer from coronary heart disease but live to be seventy or eighty years old? On the one hand, the length of life is related to genetic factors, on the other hand, it is closely related to our daily life style, or our life style determines the length of our life.
First of all, let's understand, what is coronary heart disease?
As soon as I heard about coronary heart disease, I knew there was something wrong with my heart. Coronary heart disease refers to a problem with the blood vessel that nourishes the heart, that is, this blood vessel is sick. This kind of blood vessel that nourishes the heart surrounds the heart like a crown, so it is called coronary artery. When coronary artery problems occur, myocardial ischemia and hypoxia will lead to myocardial death and even endanger our lives. Atherosclerosis is the direct cause of cardiovascular and cerebrovascular diseases. Most of us have suffered from atherosclerosis since we were teenagers. If we have a history of genetic diseases or unhealthy eating habits, it will accelerate the speed of atherosclerosis and lead to coronary heart disease.
The loss of arterial elasticity and atherosclerosis gradually increase with age, but lifestyle will determine the distance of coronary heart disease from us. A good lifestyle may never lead to coronary heart disease, but some bad lifestyles will make blood vessels harden prematurely, form plaques and lose elasticity. When these plaques fall off, they will be blocked with blood flow in the narrow official cavity. If it's a heart, it's a myocardial infarction. If it is the brain, it is a stroke.
What lifestyles are considered bad?
1, smoking and drinking
Many people know that smoking and drinking are bad habits, but they just emphasize that children can't smoke and drink. Adults who are often neglected are not poisonous when they grow up. Smoking at any age is harmful to the body, and long-term heavy drinking at any age is harmful to the heart, liver and kidneys. If you want to live a long and healthy life, you should stay away from alcohol and tobacco.
2, sedentary
The current lifestyle has reduced people's walking time, even the opportunity to walk. There is a car to go out and an elevator upstairs. In addition, the popularity of electronic products also "deprives" people of the time to go out. Staring at the computer at work, sitting all day, staring at the mobile phone after work or sitting still. Many people feel this way. Today, going out to work without a mobile phone is like losing your soul. I don't know if you feel this way.
3, greasy diet
Modern people have a good life and their level has improved a lot. Now is not the time to solve the problem of food and clothing. Eating coarse grains occasionally is to improve their lives. You can eat big fish and meat every day, and you don't have to look forward to the New Year any more. Eat whatever you want on weekdays. Coupled with busy work and study, I have less time to cook at home and more time to order takeout. Take-away food is often oily fried food for attractive taste, which will increase the intake of lipids and sugars, cause the body to digest too much lipids and sugars, and directly or indirectly affect our blood vessels.
4. Overpressure
The fast-paced life has changed many people's lives. Not only is life getting better and better, the times are developing too fast, and some of them really can't keep up with the pace. In order to adapt to the rapidly developing society, they have to bear high-intensity work and pressure. Many people often work overtime until late at night. From top to bottom, they are not only eating and drinking, but also tired of following the crowd and under great pressure. Under such pressure, we must have a good attitude. If you have poor pressure resistance, you will feel depressed or irritable, which will lead to physical dysfunction and affect your health.
5. Lack of exercise
Speaking of sports, many people will tell you that he has an annual card in a gym and often goes running or other sports. Some of these people are really exercising, and some people have never been to the gym after finishing the annual card. In fact, you don't have to go to the gym to exercise, you can also exercise at home. Old Zhong Man practices in Nanshan at home. I remember an article about a white-collar worker who seldom takes time to do physical exercise. For example, he never takes the elevator, but the escalator. When he goes to the toilet, he also uses this time to sit a few squats and so on, so don't make excuses just because he doesn't have time to exercise.
Both healthy people and patients with coronary heart disease should have a positive and optimistic attitude and maintain good living habits. As long as we receive regular treatment, it will not affect our life span. If you have a myocardial infarction, you must race against time to treat it, and you must not delay time.
Conclusion: Coronary heart disease does not mean that you have been sentenced to fixed-term imprisonment. As long as you receive regular treatment, ensure good living habits and maintain a good attitude, longevity is no problem. Therefore, people with coronary heart disease should not have psychological burden, and people without coronary heart disease should also take warning.
Coronary heart disease (CHD) refers to chronic ischemic heart disease caused by coronary atherosclerotic stenosis. A question that patients with coronary heart disease are most concerned about is: How many years can coronary heart disease live? This is a question with no clear answer. Everyone's pathological changes, age of illness and personal physical condition are different, and the degree to which coronary heart disease affects life expectancy is also different. Some patients with coronary heart disease die suddenly when acute myocardial infarction occurs, and some patients can still survive for decades after regular treatment. Coronary heart disease is an incurable chronic disease. If you don't actively treat your illness and improve your lifestyle, it will really affect your life expectancy.
So, how can I prolong the life of patients with coronary heart disease? 1. Prescribed diet
As the saying goes, illness from the mouth and bad eating habits are also important factors affecting the occurrence and development of coronary heart disease. Long-term greasy diet will lead to hyperlipidemia, too salty diet will affect blood pressure, and diabetics who eat too much and too sweet will affect blood sugar. These are the main risk factors for coronary atherosclerosis. Therefore, the diet of coronary heart disease should be light, less oil and less salt. Diabetic patients should control their appetite, avoid sweets and eat more fruits and vegetables. Generally speaking, the diet of coronary heart disease should be clear and water. Don't think that if you are sick, you should take more supplements, which will harm yourself.
take exercise
Life lies in exercise, which helps to enhance the cardiopulmonary function and control the risk factors of coronary heart disease such as hyperlipidemia, hyperglycemia and hypertension. However, exercise should also be done according to one's ability, and the intensity of exercise should be a little sweat during exercise to avoid excessive, excessive and long exercise.
give up smoking
It is very important for smokers to quit smoking as soon as possible. Smoking is an independent risk factor for coronary heart disease, and smoking in patients with coronary heart disease will aggravate the evolution of the disease.
4. Control blood pressure, blood sugar and blood lipid.
Hypertension, hyperglycemia and hyperlipidemia are the main risk factors for coronary atherosclerosis. To control the "three highs", we must first control from diet and exercise. If the control is not good, you need to use antihypertensive drugs, hypoglycemic drugs and lipid-lowering drugs respectively.
5. Drugs to prolong the life of coronary heart disease
Antiplatelet drugs include aggregation drugs, ACEI drugs, beta blockers and statins. These four drugs have been proved to be effective in improving the prognosis of coronary heart disease. To put it bluntly, it is to prolong the life span of coronary heart disease. Patients must follow the doctor's advice and take medicine regularly, and they should not change their plans at will, let alone stop taking medicine at will!
To sum up:
Coronary heart disease is an incurable chronic disease. If you don't actively treat your illness and improve your lifestyle, it will really affect your life expectancy. But as long as we actively cooperate with the specialist's treatment plan, coronary heart disease can also live with quality, and it is not a problem to live for decades! My colleague's father put three stents in the coronary artery. After regular treatment, more than ten years have passed, and he is still very healthy!
Generally speaking, people with coronary heart disease have a greater risk of death than healthy people. Patients with coronary heart disease are prone to symptoms of myocardial ischemia and hypoxia such as angina pectoris due to coronary artery stenosis and insufficient blood supply. If myocardial infarction occurs (coronary artery is completely blocked), the risk of death is higher.
Is the life expectancy of people with coronary heart disease short?
People with coronary heart disease have a higher risk of angina pectoris and myocardial infarction, but everything is not absolute. As long as regular review and active treatment are given, some patients with coronary heart disease can still live long. Patients with coronary heart disease should carry nitroglycerin or quick-acting jiuxin pills with them to dilate blood vessels and improve symptoms when angina pectoris occurs.
If the symptoms of angina pectoris are more than half an hour and the symptoms are still not relieved after taking nitroglycerin, then it is necessary to consider whether there is a myocardial infarction. If myocardial infarction is not treated in time, it is easy to endanger life. In this case, you should go to the cardiology department or chest pain center of a nearby big hospital in time. To sum up, getting coronary heart disease is a high risk factor, but it is not necessarily short-lived. The key depends on the control and treatment of the disease.
The full name of coronary heart disease is coronary heart disease, which is very common in clinic. It is a syndrome that coronary artery stenosis and occlusion lead to myocardial ischemia, hypoxia and necrosis due to various reasons. According to the different conditions, we can divide coronary heart disease into five categories: asymptomatic myocardial ischemia, angina pectoris, myocardial infarction and sudden death.
Many people are very worried after the diagnosis of coronary heart disease, thinking that it will greatly shorten life expectancy and endanger life. In fact, this understanding is incorrect. Most patients with coronary heart disease can control their illness and prolong their life through active and standardized treatment. However, if people do not pay attention to it and actively treat it, it will not be conducive to disease control, increase the occurrence of complications and endanger life, especially for patients with frequent angina pectoris and acute myocardial infarction, which need timely treatment.
The treatment measures of coronary heart disease mainly include lifestyle intervention, drug therapy, stent intervention and surgical treatment. We should actively seek medical treatment, and under the guidance of professional doctors, make individualized plans after fully evaluating the illness, so as to stably control the illness, reduce complications and improve the quality of life.
In daily life, patients with coronary heart disease should pay attention to reasonable diet, quit smoking and limit alcohol, exercise properly, control weight, work regularly and maintain a good attitude, pay attention to the use of aspirin and statins, choose drugs such as beta blockers according to the condition, actively treat basic diseases such as hypertension, diabetes and hyperlipidemia, and control blood pressure, blood sugar and blood lipid to reach the standard. For patients with coronary artery stenosis above 75%, frequent angina pectoris, acute myocardial infarction, etc. , it is recommended that stents intervene. For patients with complicated condition and restenosis after stent implantation, surgical treatment can be considered if necessary. While receiving regular treatment, we should also pay attention to monitoring the changes of the disease and review it regularly.
Coronary heart disease is a common disease, which belongs to a kind of heart disease. When the disease is serious to a certain extent, it will do great harm to the body and also have an impact on life. If the body has diseases, it will inevitably have an impact on life. Only by actively treating diseases can we enjoy life better.
The history of patients with coronary heart disease is positively related to their life span, because the coronary circulation has great potential, and the branches of coronary arteries are like criss-crossing rivers, with many branches supplying blood to myocardium. On the other hand, it is closely related to patients' own health care consciousness. On the other hand, in order to prolong the life span of patients with coronary heart disease, on the one hand, we should try our best to develop the potential of coronary circulation, enhance the ability of coronary perfusion and promote myocardial blood supply, on the other hand, we should strengthen health care.
Coronary artery is like a crisscross river, which is composed of main roads and branches. Usually, blood mainly enters the myocardium through the "main channel", but if the larger branches of the coronary artery are blocked, blood can also improve blood supply to the myocardium through the "small river" of each branch, which is the collateral circulation of the coronary artery. Usually, this coronary collateral circulation is in a deep sleep state, so angina symptoms will appear when myocardial ischemia occurs, myocardial infarction will appear when severe ischemia occurs, and even serious arrhythmia will be caused, leading to sudden death.
Proper physical exercise can promote blood circulation and help establish collateral circulation. But the amount of exercise should be done according to one's ability. When there is palpitation, shortness of breath, dizziness, chest tightness, fatigue after exercise, poor sleep and loss of appetite during exercise, it means that the amount of exercise is too large and should be reduced appropriately. People with coronary heart disease should strengthen daily health care, avoid tension and fatigue, remain optimistic, relaxed and open-minded, quit smoking and limit alcohol, eat less foods with high animal fat and cholesterol, strictly control salt and sweets, insist on taking medicine and check regularly. People with coronary heart disease can also live long.
