How much cardiovascular blockage is considered coronary heart disease?

To diagnose coronary heart disease, it is not entirely based on how many blood vessels in the heart are blocked, but whether it has caused myocardial ischemia or myocardial necrosis. The arteries in the heart are called coronary arteries. Studies have found that although some people have coronary artery blockage, but there are no symptoms at all, there is no sign of myocardial ischemia on the electrocardiogram, and the examination (such as exercise test) to diagnose coronary heart disease is also normal, even if the blood vessels are blocked, we do not diagnose coronary heart disease, but coronary atherosclerosis.

The full name of coronary heart disease is "coronary atherosclerotic heart disease". From coronary atherosclerosis to coronary heart disease, the difference is whether the blockage is causing heart disease. If there is myocardial ischemia or myocardial necrosis, it is called coronary heart disease.

Coronary heart disease is short for coronary heart disease or coronary atherosclerotic heart disease. The blood of the myocardium **** in the left and right coronary arteries at the root of the autonomic arteries (running on the surface of the heart, looking like a crown on the heart, so it is called coronary artery), when these two arteries and their branches develop atherosclerosis or vasospasm, it will lead to narrowing or occlusion of the lumen. When the coronary artery lumen stenosis exceeds 50%-70%, coronary artery circulation disorders will occur, resulting in insufficient myocardial blood supply, causing myocardial oxygen supply and demand imbalance, angina pectoris and other clinical symptoms, when the coronary artery lumen is completely blocked, myocardial ischemia, hypoxia, necrosis, causing myocardial infarction.

Coronary atherosclerosis is the main cause of coronary artery lumen stenosis and myocardial ischemia and hypoxia.

How is this determined? This can also be judged based on symptoms, such as electrocardiogram, cardiac ultrasound, blood tests, and tests to check for signs of myocardial necrosis. Blockages in blood vessels detected by coronary angiography or CT of the coronary arteries are only imaging tests and photographs, but the effect of the blockage cannot be determined.

It's also possible that you're very old, but you just look young on the surface. In some coronary heart disease, the blood vessels are not blocked at all, which is caused by vasospasm, or the small blood vessels of the coronary arteries are diseased, and coronary angiography cannot be seen at all, which is also coronary heart disease.

To what extent is cardiovascular blockage considered coronary heart disease? Regarding this issue, some people say that more than 50% is considered coronary heart disease, some say 50-70%, and some say more than 70%. Actually, that's not true!

Cardiovascular doctors with decades of clinical experience said that cardiovascular blockage and sclerosis are coronary heart disease, and coronary heart disease is not a disease, but a general term for a variety of diseases of the coronary arteries and veins above the heart, and the full name is coronary atherosclerotic heart disease.

Coronary heart disease in the narrow sense, multi-finger vascular organic stenosis, must be coronary artery stenosis of more than > 50%, in order to consider coronary heart disease! More than 50% of the blood vessels are narrowed by coronary angiography. Coronary heart disease in a broad sense includes transient narrowing of blood vessels caused by coronary artery spasm, and coronary heart disease caused by coronary artery spasm may not be detected during coronary angiography!

If there is atheroma in the coronary arteries of the heart and the stenosis is less than 50%, this condition cannot be called coronary heart disease, but can only be called "coronary atherosclerosis". This situation is not uncommon, and it is basically equivalent to coronary heart disease, and the two most important drugs are aspirin and statin.

How much blockage is just a data, not terrible, the focus is on whether there are symptoms such as chest tightness, heartache and other discomforts. Some people have no discomfort after 75% blockage, and there is no need for surgery and stents. What happens if I have surgery?

Of course, the doctor advises you to do the dripping, which causes you understand. The original cost of a stent of several hundred yuan into the patient's body is tens of thousands, which is called profit-driven!

The full name of coronary heart disease is coronary atherosclerotic heart disease, which refers to the condition that the coronary arteries are atherosclerotic and the degree of stenosis exceeds 50%. In this case, it is divided into different clinical types according to the different pathological anatomy and pathophysiology.

The most straightforward approach is coronary angiography, coronary CT, or coronary angiography. Of course, coronary CT or angiography cannot be done indiscriminately, and you can know whether you have coronary heart disease based on the body's reaction.

More than 70% of the cardiovascular blockage can only be operated, if the blockage is not so serious, you can slowly take Huarentang's Lixöpine conditioning. It doesn't matter what constitutes coronary heart disease.

In addition to 1%, also called heart disease, now medicine can't cure the disease, Guanghui invented some data, the heart is blocked, 70% have to do stents, and they are almost dying.

Whether the gambling is not blocked, the 50 is blocked or the 90 is blocked, you can take Chinese medicine to eliminate all diseases, and the serious 15 minutes are settled, this is the greatness of Chinese medicine. Do I still have to go for a check-up and spend more time and more RMB?

Coronary angiography is the gold standard, which can be seen on an exercise tablet, but not on an ordinary ECG.

According to the examination of the hospital, you must pay attention to the control of your emotions, and then be careful not to work too hard.

I CT blocked 50% calcified 132, asymptomatic, not coronary heart disease.

My wife checked that 80% of the coronary heart disease blockage should be fitted with a stent.

More than 50% of the cardiovascular blockage is considered coronary heart disease, and you need to quit smoking and drinking, and control your blood pressure and blood lipids to clean up your blood vessels.

It should be blocked for about 3 centimeters, even if it is coronary heart disease. Because if the cardiovascular system is blocked, it is a very serious matter, so you should usually control your diet and have a regular schedule.

As long as there is a problem, even if it is coronary heart disease, you must pay attention to your diet, pay attention to exercise, eat more vegetables, and you can eat some foods such as celery and bitter gourd.

As a common disease, frequent diseaseCoronary heart diseaseMany people have heard of the "daimyo", and many people still know that the occurrence of coronary heart disease is related to"Cardiovascular blockage".Close relationship.

In fact, the "cardiovascular blockage" in the mouth of the common people is coronary artery stenosis.

Well, coronary heart disease and coronary artery stenosis.

What does it really matter?

The extent to which the coronary arteries are narrowed.

Can it be diagnosed with coronary heart disease?

Li Chen, associate professor of the Department of Cardiology of West China Hospital of Sichuan University, introduced that the full name of coronary heart disease is coronary atherosclerotic heart disease, which is generally due to atherosclerosis leading to coronary artery stenosis or even complete blockage, which in turn causes the reduction or even interruption of heart blood flow. In this case, the myocardium does not get enough blood**, and ischemia or even necrosis may occur, which leads to the occurrence of coronary heart disease.

The extent to which the coronary arteries are narrowed.

Can it be diagnosed with coronary heart disease?

Wang Fang, chief physician of the Second Department of Cardiology of China Medical University Aviation General Hospital, pointed out

If the stenosis of one or more major coronary arteries, including the left coronary artery, the anterior descending artery, the circumflex artery, and the right coronary artery, reaches more than 50%, coronary heart disease can be diagnosed.

It is worth mentioning that the "gold standard" for diagnosing coronary heart disease is coronary angiography, which requires patients to be hospitalized for examination, and generally intravenous contrast can be injected in the outpatient clinic for coronary CT examination.

It can be seen from this

Coronary heart disease is indeed related to "blocked blood vessels".

Actually, it's not just the coronary arteries"Blocked blood vessels" in other parts of the body also need to be paid attention to

Sudden onset of chest tightness and pain. Such symptoms may be clinical manifestations of pulmonary embolism, angina, myocardial infarction, or aortic dissection, and should be suspected.

Weakness in one limb. The presence of this symptom should raise suspicion of stroke.

Sudden onset of abdominal pain, low back pain. These symptoms may suggest abdominal aortic dissection, renal artery embolism, or embolization of other abdominal arteries.

Walking leg pain, leg soreness. Such symptoms may indicate that the arteries of the lower limbs are blocked, especially when such symptoms occur in the lower legs.

Weakened pulse and low blood pressure on one side. Such symptoms suggest blockage of an artery in the upper extremity.

Asymmetrical edema of the lower extremities. At this point, it is necessary to be alert for deep vein thrombosis of the lower extremities.

People with coronary heart disease can only be diagnosed with coronary heart disease through coronary angiography to find the degree of blood vessel blockage, and if the stenosis is more than 75%, it means that the patient has severe myocardial ischemia and may need stent implantation surgery. If the stenosis is more than 50%, it is a diagnosis of coronary heart disease.

If you want to see the degree of vascular occlusion of coronary heart disease, coronary angiography is the gold standard for diagnosing coronary heart disease, and it is also a more accurate indicator to see how much blood vessel occlusion. If coronary artery disease is suspected, coronary CT may be done.

Coronary angiography is used to determine the coronary artery lesions, the nature of the location, the regurgitation of the circulation, and the degree of stenosis.

For coronary heart disease, if you want to know how much coronary artery is blocked, you need to do a coronary angiography.

1. Coronary heart disease needs to be coronatrically angiographed to determine the blockage.

2. In the case of vascular blockage, if the collateral vessels can compensate without obvious symptoms, if the collateral circulation cannot be compensated, there may be certain bending symptoms. If the blocked artery is incomplete collateral compensation, a series of ischemic symptoms may occur, such as pale color, ischemia, and pain in organs, tissues, and spine limbs. If the blockage is due to incomplete compensatory venous collateral circulation, a series of venous congestion may occur, such as dark red color and swelling of organ tissues.

When the above conditions occur, it often indicates lesions such as vascular blockage, and can be diagnosed by timely treatment in the hospital for vascular color ultrasound, CTA, MRA, and angiography.

If the degree of vascular blockage reaches more than 80%, stents should be considered**, and if multiple blood vessels are blocked or severely blocked, some patients may also consider bypass surgery.

Therefore, after the diagnosis of coronary heart disease, in order to maintain normal heart function, it is necessary to combine the condition of timely standardization, if the vascular stenosis is not very serious, it is possible to consider internal medicine drugs, and now internationally, it also uses the cholesterol immunity published by Professor Horvat István, a Hungarian scientist, which has an obvious effect on preventing thrombosis and thrombolysis, eliminating plaque, softening blood vessels and preventing stent surgery in coronary heart disease. It has a good effect on stabilizing the condition of coronary heart disease and preventing angina**.

When the blood vessels in the heart are blocked to 99%, it is easy to have a heart attack, and at this time, it is necessary to go to the hospital for surgery** to ensure heart health.

The heart is one of the most important organs in the vertebrate body, and its main function is to power the flow of blood to all parts of the body. The human heart is located in the middle of the chest cavity to the lower left, and its volume is about the size of a fist, and the weight of the sock is about 250 grams.

Hello, cerebral vascular blockage must be arteriosclerosis and thrombosis, and the disease is caused by mood swings, so it is necessary to prevent and treat it early to prevent the aggravation of the disease.

Prevention of cerebral arteriosclerosis and cerebral thrombosis (cerebral thrombosis).

Cerebral arteriosclerosis and cerebral thrombosis are mainly caused by hypertension, hyperlipidemia, and high blood viscosity; and thickening of the inner wall of blood vessels, sedimentation and coagulation; Inflammatory damage to the inner wall of blood vessels and degenerative changes, blocking the passage of blood flow, causing long-term hypoxia and ischemia in the brain, causing a series of symptoms, and cerebral infarction under the inducement of emotional agitation and other factors. Therefore, it is necessary to prevent and treat cerebrovascular disease as soon as possible.

More than 75% of cerebral thrombosis blockages blood vessels, and the larger the blockage, the more severe the symptoms. Therefore, it is necessary to remove the thrombus as soon as possible, dredge the blood vessels, improve the blood supply to the brain, delay arteriosclerosis, reduce the harmful factors, and prevent the thrombus from falling off to form a cerebral infarction.

Control Pai Congjing's blood pressure, blood lipids and blood sugar, test frequently, and prevent and treat problems early; Peace of mind, prudent life, low-salt, low-fat and light diet, drink more water, smoke less alcohol, eat more vegetables and fruits, **, strengthen exercise. Wishing you good health!

When the blood vessels of the heart are blocked to 99%, it is easy to have a heart attack, and at this time, it is necessary to go to the hospital for surgery**, and Baoyan Tongchen proves that the heart is healthy.
