Why is hypertension prone to cerebral infarction?
Why is hypertension prone to cerebral infarction?
"Old Four" is a bully in the vegetable market, so Old Four, not that he usually how to bully people, but that his business is doing well. Lao Si has been selling vegetables in the market for more than twenty years, when he was in his teens, he came out to sell vegetables, and in his forties, his vegetable market is the largest vegetable business. Old four usually hard to imagine, usually more than 3:00 get up to go to the vegetable wholesale market on the vegetables, back in the morning to drink a bowl of "goat soup", eat 5 big fries, and then two small dishes of pickles, every day so. Lao Si's temper is also big, usually to others always anxious, so everyone is a little afraid of him. Lao Si knows that his blood pressure is high, but do not feel uncomfortable, also did not see the winter of 2009, Lao Si in the process of sudden hard resistance to vegetables, suddenly cerebral infarction admitted to the hospital, and finally, although the life saved, but people are disabled, selling vegetables is impossible, can only be hemiplegic at home every day.

In fact, many friends will ask why Lao Si had a sudden cerebral infarction. It is actually related to the fact that high blood pressure can lead to the occurrence of atherosclerosis. So, why can uncontrolled hypertension lead to the development of atherosclerosis?
This is because long-term hypertension, if not effectively controlled, can make the arterial vascular endothelial damage proliferation, thickening, accompanied by lipid accumulation, so that the lumen area is impaired, that is, the old people say that leads to blood vessel narrowing, which is the pathological basis of the formation of atherosclerotic plaques. Hypertension causes atherosclerotic changes in the arterial system, which leads to the occurrence of coronary heart disease, cerebral infarction and other cardiovascular diseases.

In fact, cases of cerebral infarction occurring in Lao Si because of high blood pressure are not uncommon, and it can even be said that they are very common. This is because the greatest danger of hypertension is cerebral infarction. It can be said that this is much more than the patients with coronary heart disease brought about by high blood pressure. Therefore, if you have high blood pressure, must control the blood pressure, at the same time pay attention to the state related to cerebral infarction and usual physical examination.
At the same time, it must be said that we can learn a lot of lessons from Lao Si's occurrence of cerebral infarction, such as his obese body type, high salt, high fat and high sugar diet, staying up all night, smoking and drinking, and his high blood pressure not being controlled, which ultimately led to the tragedy. This also reminds us of how we should improve our lifestyle and control our risk factors, so as to avoid the tragedy brought about by high blood pressure.

Our country is a big country of cardiovascular disease, there are currently 13 million cerebrovascular in our country, and this number is still increasing. One of the main reasons is that we are a big country with high blood pressure, there are 245 million hypertensive people in China, and these people may develop cerebral infarction if they don't have formal and effective control of high blood pressure.
How does high blood pressure cause cerebral infarction? Let's take a look at cerebral infarction, cerebral infarction simply means that cerebrovascular atherosclerosis is aggravated, causing narrowing of cerebral blood vessels or neck blood vessels, plaque aggravation, plaque rupture will form a thrombus, and cerebral infarction will be formed.
That is to say, atherosclerosis is a major root cause of cerebral infarction, and how does high blood pressure lead to aggravation of atherosclerosis? Suffer from high blood pressure, no feeling does not mean no damage, if there is no control of blood pressure, with the development of the disease, small arteries gradually hardening, medium and large arteries appeared in the lining of lipid deposition, the formation of atherosclerotic plaque, and ultimately rupture of the plaque will form a thrombus, the occurrence of acute myocardial infarction.
It's a bit complicated, so let's take a look at the following diagram to understand more clearly the effects of high blood pressure on the inside of the blood vessels.
The effects of high blood pressure on the lining of blood vessels are readily apparent, so I want to be active and formal in controlling my blood pressure.
When long-term high blood pressure is not effectively controlled, the blood vessels will produce more garbage, and when more and more of this vascular garbage accumulates, plaque is formed, and when the plaque ruptures, a blood clot is formed.
Prevention of high blood pressure, the main purpose is to prevent various complications of high blood pressure. When long-term high blood pressure is not controlled, or poorly controlled, it will form heart, brain and kidney various hypertension complications ......

High blood pressure in life is very common, cerebral infarction is also very common, many hypertensive people suffer from cerebral infarction risk is very high, many people will be hypertensive cerebral infarction these two diseases together, got high blood pressure cerebral infarction chances are very high, the two diseases are also very close to the link between the two in the end what is the link between them, why is it easy to suffer from cerebral infarction of high blood pressure people?
In the physiology of long-term hypertensive people, sustained high-pressure blood flow will make the arterial wall of the endothelium damage, endothelial damage rupture, blood cholesterol into the broken blood vessel wall, over time, more and more cholesterol deposits will form plaque, if hypertension is not treated in a timely manner, plaque is getting bigger and bigger, will cause the lumen of the blood vessel is significantly narrowed, and over time it will cause cerebral ischemia. At the same time, with the rupture of the plaque will also form a blood clot completely blocking the blood vessels, that is, we often say the occurrence of cerebral infarction, it is not difficult to see, hypertension caused by cerebral infarction is very high, you must have to control high blood pressure in order to effectively prevent cerebral infarction.
There are a lot of people do not care about high blood pressure, perhaps a short period of time of elevated blood pressure on the body's impact is not great, many people feel that high blood vessels in fact nothing, but this is not the case, the initial high blood pressure may be nothing obvious to the body or can be perceived as damage, long-term high blood pressure will cause a lot of discomfort, such as headache, dizziness, palpitations, tinnitus, emotional easily agitated, and so on, will also cause the body of vital organs damage and dysfunction, such as heart disease, cerebrovascular disease, kidney disease, cerebrovascular disease hypertension accounts for 50-60%. It can also cause damage and dysfunction of important organs, such as heart disease, cerebrovascular disease, kidney disease, etc. Cerebrovascular disease hypertension accounts for 50%-60%, therefore, do not be careless with high blood pressure, we should actively treat it to maintain blood pressure to the normal ideal level, and minimize the damage to the body!

Hypertension is a common chronic disease, but also the most important cardiovascular and cerebrovascular risk factors, affecting the structure and function of important organs, such as: the heart, brain, kidney, and ultimately can lead to the failure of these organ points. Today I will talk to you about why hypertension is prone to brain infarction.
Prolonged hypertension causes ischemia and degeneration of cerebral blood vessels, forming microaneurysms, which can lead to cerebral hemorrhage. Hypertension can cause atherosclerosis of the cerebral arteries, and rupture of the atheromatous plaque can complicate cerebral thrombosis. Occlusive lesions of small cerebral arteries can lead to small infarct foci, also known as lacunar cerebral infarction. The sites of cerebral vascular lesions in hypertension are particularly favorable in the middle cerebral artery of the douglas artery, the paracentral artery of the basilar artery, and the cerebellopontine nucleus arteries. These vessels come directly from high pressure arteries, are thin and vertically penetrating, and are prone to microaneurysm or occlusive lesions.
Approximately 70% of patients with ischemic stroke have elevated blood pressure in the acute phase. The main reasons for this include the presence of pre-morbid hypertension, pain, nausea and vomiting, increased intracranial pressure, confusion, anxiety, and post-stroke stress. Patients with elevated blood pressure within 24 h after ischemic stroke should be treated with caution. Stress, anxiety, pain, nausea, vomiting, and increased intracranial pressure should be managed first. Patients with persistently elevated blood pressure, systolic blood pressure ≥200 mmHg or diastolic blood pressure ≥110 mHg, or with severe cardiac insufficiency, aortic coarctation, or hypertensive encephalopathy can be treated with antihypertensive therapy, and changes in blood pressure should be closely observed. Intravenous drugs such as labetalol, nicardipine, etc. can be used, and drugs that cause a sharp drop in blood pressure can be avoided. After stroke, if the condition is stabilized, the blood pressure continues to be ≥140mmHg/90mmHg, and there is no contraindication, the use of antihypertensive drugs taken before the onset of the disease can be resumed or the initiation of antihypertensive therapy can be started several days after the onset of the disease.

People who suffer from high blood pressure are well aware of the fact that during the course of their illness, they may contract other diseases or complications due to this disease, and "cerebral infarction" is one of the complications. However, many people are curious as to why two apparently unrelated diseases can strike at the same time, is it a coincidence or is there a connection?
In fact, hypertension itself is a disease caused by changes in blood pressure, and the human body itself blood flow to all organs, there is blood pressure everywhere, so as long as a place where the blood pressure changes abnormally, then it means that may lead to other places also have problems. There is a saying that "one hair affects the whole body".
In fact, a more scientific way of saying it is that high blood pressure is a disease that can lead to abnormal changes in blood pressure throughout the body when it strikes, and the abnormal blood pressure will make the blood vessels in various parts of the patient's body do not adapt, which may lead to changes in the width and elasticity of the blood vessels, or changes in the cells, such as necrosis, which may lead to a lack of blood supply in certain places, such as the brain, the heart, and so on, or even blockage, and the symptoms that eventually appear are what we may see as cerebral infarction or other symptoms. The symptoms that eventually appear are what you may see as brain infarcts or other symptoms.
The inconvenience brought by cerebral infarction is unimaginable. It should be known that during the onset of cerebral infarction, the patient's ability to control various parts of the body is greatly discounted or even completely uncontrollable, such as paraplegia, inability to use hands to hold things, and so on. It is precisely because we understand the danger of cerebral infarction that we should pay more attention to high blood pressure, which may lead to cerebral infarction. When you recognize that you are suffering from high blood pressure, you should take action immediately, follow your doctor's advice to take medication, improve your lifestyle and diet, and actively exercise to prevent high blood pressure from aggravating and causing cerebral infarction!

Cerebral infarction is one of the more common complications in hypertensive patients, why are hypertensive patients prone to complicate cerebral infarction? That is to influence each other to promote, hypertensive patients are more than 8 times more likely to complicate cerebral infarction than normal people.
Hypertensive pathology:
Hypertension, hyperlipidemia and hyperglycemia are common problems in our life. Many people have wrong understanding of hypertension, thinking that since hyperglycemia and hyperlipidemia are excessive impurities in the blood, hypertension is also a blood disease, but in fact, hypertension is actually a vascular disease, due to the hardening of blood vessels, resulting in thinning of blood vessels and thickening of blood vessel walls, so that when the blood flows, the blood transfusion volume will be reduced and the amount of oxygen will be reduced. When the blood flows in the blood vessels, the walls of the blood vessels will bear more impact from the blood flow, and the pressure of the blood on the walls of the blood vessels is the "blood pressure", and if the pressure of the blood on the walls of the blood vessels is too strong, we often say "hypertension". Excessive pressure of blood on the walls of the blood vessels is what we often call "high blood pressure".
Cerebral infarction pathology:
It refers to the cerebral blood vessels have a blood supply obstacle, the occurrence of ischemia, hypoxia, resulting in local necrosis or softening of brain tissue, so that the loss of functionality, the common clinical factors are cerebral thrombus blockage of cerebral blood vessels, or due to the occurrence of cerebral vascular sclerosis.
Pathologically, the underlying causes of the condition are due to vascular pathology, where high blood pressure is able to stimulate the vascular hormone blood vessels to harden and thin.
Cerebral infarction is caused by the hardening of the blood vessels in the brain (which are more fragile and prone to lesions), which makes them more susceptible to thrombotic blockage.
In other words, patients with hypertension are more likely to develop cerebral infarction because both diseases have a vasculopathic basis and their pathogenesis is not conflicting, they can coexist and will be interrelated, and they can also accelerate each other's course.
What is high blood pressure in the first place?
Blood pressure ii myocardial contractility x effective circulating blood volume x peripheral small artery resistance
1. When the body is ischemic the body through sympathetic excitation so that the peripheral small arteries contract to increase resistance to increase blood pressure, to maintain the blood supply of the body's tissues.
2. When the body is ischemic, the blood supply to the tissues of the body is maintained by increasing myocardial contractility and heart rate.
3. When the human body ischemic body in order to protect the important organs of the brain, due to the contraction of peripheral small arteries, other organs and tissues of the body are in a relative ischemic state, the effective circulating blood in order to maintain the blood supply to the brain, tissues and organs of the microcirculation of the part of the arterial and venous blood vessels open to ensure the effective circulating blood to improve the cerebral ischemia.
Relationship between hypertension and cerebral infarction
When the large long-term cerebral blood supply is insufficient, can not be improved, the peripheral small arteries are in a state of continuous spasm, the body's small arteries also reduces the blood supply, which causes damage to the vessel wall, when the body is subjected to external sudden stimuli such as persistent cold, emotional excitement, etc., the sympathetic excitation rapidly excitation so that the peripheral small arteries continue to spasm, the blood pressure is further increased due to the cerebral arteries continue to spasm so that the blood vessel wall damage further aggravated and the formation of thrombus.
Due to the insufficient blood supply to the brain to raise blood pressure, leading to chronic ischemia in various tissues and organs of the body, such as the liver, pancreas, gastrointestinal chronic ischemia, so that their sugar, protein, fat metabolism is impaired, resulting in elevated blood glucose, elevated blood lipids, elevated uric acid.
take precautions against
The main solution to the body tissue ischemia, especially the brain blood supply, the cause of insufficient blood supply to the brain is mainly cervical spondylosis of the vertebral artery type and sympathetic type, these two types are mainly by the circumflex joints contusion, circumflex occipital fascial stenosis compression of sympathetic nerves and the vertebral artery and lead to insufficient blood supply to the brain. Therefore, the active prevention of cervical spondylosis is the key construction.
Cerebral Embolism Treatment
1. Acute cerebral embolism treatment, blood cerebral vascular intervention within 3 hours is the only good effect of the treatment of cerebral embolism, when the cerebral embolism, we will be catheterized directly to the thrombus, with a large number of urokinase directly to the thrombus dissolution. If the catheter can't reach the thrombus, thrombolysis is basically ineffective.
2. Intravenous drug thrombolytic therapy is ineffective and harmful to the human body. The reason, people who have studied physics know that when a water pipe is completely blocked after the water is not flowing, so the intravenous infusion of thrombolytic drugs can be to embolize the non-flowing blood vessels? And the concentration of intravenous drugs can thrombolysis?
Hazards: I talked about this in the article about using aspirin for high blood pressure, but there are still a lot of people who aren't aware of it, so I'll review it again for you for a change.
The bleeding and coagulation system in the body is balanced. When our body bleeds, it coagulates to stop the bleeding, which is where our clotting factors come in. When we bleed and form hematomas and thrombi are absorbed, it relies on our anticoagulation factors. So our coagulation factors and anticoagulation factors are balanced.
When we enter a large amount of thrombolytic drugs intravenously, the body must produce clotting factors to balance the foreign hemolytic factors. When the large amount of foreign hemolytic factor exceeds the insufficient amount of clotting factor produced by the body's own regulation, it cannot counteract the foreign hemolytic factor and life-threatening bleeding occurs in the embolized area. Clinically, it is found that the chance of bleeding increases significantly after one week of intravenous injection.
Why is it easier to have another infarction after having an infarction? When we enter hemolytic factor into the vein, the body produces a large amount of coagulation factor for the sake of the balance of the hemorrhagic and coagulation system, and at this time, we suddenly stop using the hemolytic factor that we enter into the vein, and then there is a relative hypercoagulability in the body and the infarction occurs again.
Nowadays, many hypertensive middle-aged and elderly people are infused with anticoagulants once or twice a year to prevent cerebral infarction. He and they are not doing health care but creating diseases.
The human body has a powerful self-repairing and disease-fighting system. As long as we live in peace with nature, let nature take its course, maintain a good state of mind, keep a good night's sleep, maintain good dietary habits, keep the two stools smooth, protect our spine. All diseases will not invade.
The effect of long-term hypertension on brain tissue, whether cerebral infarction or cerebral hemorrhage, is the consequence of cerebral vascular disease. Long-term hypertension damages the endothelium of blood vessels, and then lipid infiltration, slowly line into atherosclerotic plaques, like water pipes slowly damaged, the cerebral blood vessels also become less open, ischemia and degeneration will occur, these atherosclerotic plaques rupture can be complicated by cerebral thrombosis line into. Cerebral small artery occlusive lesions, causing pinpoint infarction foci, known as lacunar cerebral infarction. The cerebrovascular lesions of hypertension are especially likely to occur in the middle cerebral artery, such as the bean artery, because these blood vessels come directly from the large arteries with high pressure, and the blood vessels are long and thin and vertical, which can easily lead to microaneurysms or occlusive lesions.
The above can be seen hypertension caused by cerebral infarction is the main factor is high blood pressure on the vascular endothelial damage, damage to the fat after claiming false entry, so hypertensive patients to prevent cerebral infarction, the current clinical commonly used in the three techniques, 1, choose the right antihypertensive medication on time to control blood pressure, 2, try to look at the patient's situation may be a small measure of practical worship Aspirin (especially hope that there has been a history of cerebral infarction, if there is no cerebral infarction in the past, but There may be insufficient blood supply to the brain, it will be recommended to take some blood talking Chinese medicine, I do not know if I can mention the name of the drug, for fear of being said to advertise) 3, is a statin lipid-lowering drugs, a can lower lipids, even if the blood fat is not high, can also take, because it also has a second role is to stabilize the plaque, because the cerebral infarction is the plaque is unstable rupture or fall off caused by well.
Thanks for watching.
Hello and thank you for your question!
Hypertension is a "disease of the rich", is very common in life, can cause heart, brain, kidney and other organs of the complications, seriously jeopardize the health of human beings.
Why are you prone to cerebral infarction when you have high blood pressure?
Hypertension makes the blood pressure unstable, the blood makes the blood vessels form thrombus or the elasticity of the blood vessel wall decreases, the blood vessel narrows, to a certain extent, the blood supply of the cardiac cells is insufficient, the cardiac cells degenerate and necrotic, and infarction occurs, if the formation of thrombus, especially cardiogenic thrombus with the circulation into the small cerebral blood vessels, it will cause cerebrovascular infarction. Simply put, hypertension is a cardiovascular risk factor, making hypertensive patients with myocardial infarction and cerebral infarction probability increases, atherosclerosis, vascular stenosis and the original coronary atherosclerosis on the basis of the thrombus breakthrough caused by vascular blockage.
Patients with cerebral infarction mostly develop the disease when they are resting quietly. Some patients wake up with a start and find that their mouth and eyes are askew, they are paralyzed, drooling, dropping grains of food, and they can't move their chopsticks, which can catch people off-guard.
Cerebral infarction caused by high blood pressure should not be underestimated, the fundamental strategy to prevent the disease or control blood pressure, usually pay more attention to their own bodies, if you feel unwell to quickly consult a doctor, must not be delayed, so as not to delay the condition.
Thank you for your question and I hope it helps!
Let's start with cerebral infarction, which is a cerebral infarction, a cerebral thrombosis. Generally speaking, cerebral thrombosis is caused by platelets gathering in the radial artery to form a thrombus, blocking the blood flow and leading to a cerebral infarction.
The reason why high blood pressure can cause cerebral infarction is because, high blood pressure will squeeze the inner wall of the blood vessels, is the inner wall of the blood vessel rupture, the inner lining of the blood vessels in some lipids, such as cholesterol, etc., will enter the blood disease adhering to the inner wall of the blood vessels to form plaques, with the flow of blood, blood platelets in the blood will slowly gather in the vicinity of the platelet, which further increases the growth of the platelet. Slowly forming a blood clot.
In summary, we can know that high blood pressure should be detected and treated early, perhaps a moment of high blood pressure does not have how serious symptoms, but, implicitly, it will cause all aspects of the human body's blood vessels damage, and, at the beginning of the endothelial rupture of the blood vessels does not have any symptoms. Once the onset of the disease is too late.
Therefore, to treat cerebral infarction, on the one hand, high blood pressure should be controlled. On the other hand, it is also necessary to control blood lipids.Be sure to go to the hospital to confirm the diagnosis and reasonable treatment. To control blood pressure, you can use Pingxin, Fuxin, and Resuxin. There are also many to control blood lipids, if it is the early stage, you can use lifestyle adjustment to control.
