Cerebral Infarction How does a heart attack occur? What is the whole process of a blood vessel block

The whole process of blood vessel blockage is very complicated, first of all, we will cause excessive hormone secretion in the brain due to excessive fright or overexcitement, resulting in a corresponding increase in hormones in the blood vessels, resulting in an increase in cholesterol content, once its content in the blood increases, it will cause the accumulation of cholesterol in the blood vessels, resulting in blood flow not passing, which will cause cerebral infarction and myocardial infarction.

The most important thing is the disease of blood vessel blockage and then formation, there is this phenomenon of cerebral infarction in an instant, and it is very likely that a blood vessel will be blocked in the past, the whole process is actually the process of blood circulation at that time, and then there is a blood clot blocked in front, which is such a formation.

Cerebral infarction and myocardial infarction are ischemic vascular lesions, and some bad lifestyles such as smoking and drinking alcohol can cause damage to the vascular endothelium, which will cause platelets and red blood cells to accumulate at the broken part of the blood vessel when the components in the blood flow through, and some plaques will slowly form, and the arterial blood vessel narrowing and blood flow will slow down, and it is easy to occlude the blood vessel position.

Cerebral infarction, also known as ischemic stroke, is a common cerebrovascular disease. Patients with cerebral infarction can be caused by a variety of reasons, and the routine can be analyzed from the following aspects.

1. Vascular wall lesions may cause cerebral infarction, and common causes of vascular wall lesions include hypertension, atherosclerosis, drug poisoning, trauma, puncture injury, and congenital vascular malformation and stenosis.

2. Cardiac and hemodynamic changes, common coronary heart disease patients, rheumatic heart disease patients, patients with high or low blood pressure, that is, common hypertension and hypotension; Patients with rheumatic heart disease often have arrhythmias, especially those with atrial fibrillation, which are prone to cerebral infarction;

3. Changes in blood composition, blood viscosity or hemoconcentration, seen in patients with hyperlipidemia, anemia or polycythemia, cerebral infarction caused by increased blood viscosity;

4. Others** include air embolism, tumor cell occlusion of blood vessels or parasites, etc.;

5. A very small number of patients with cerebral infarction are currently unknown.

Cerebral infarction is a blockage of cerebral blood vessels, which can be divided into atherosclerotic thrombotic cerebral infarction, lacunar cerebral infarction, cerebral watershed infarction and cerebral embolism according to the different causes.

The main causes of atherosclerotic thrombotic cerebral infarction include hypertension, hyperlipidemia, hyperglycemia, and hyperhomocysteinemia. Patients may be due to atherosclerosis, which causes narrowing of the lumen and stiffness of the tube wall, which leads to blockage of blood vessels and causes cerebral ischemia and hypoxia, resulting in cerebral avascular necrosis or malaciation. If the patient has a massive cerebral infarction, there may be hemilimb sensorimotor impairment, consciousness impairment, and in severe cases, death.

If the patient has a cerebral embolism, most of them are due to a cardiac embolus detaching and blocking a blood vessel, or a thromboembolus of a large artery that breaks off and blocks a blood vessel.

In the case of lacunar cerebral infarction, it is mostly caused by occlusion of terminal small blood vessels caused by long-term hypertension, and if the patient has a cerebral watershed infarction, most of the reasons are due to hypoperfusion.

Blockage of blood vessels caused by cerebral infarction needs to be carried out in time**, otherwise it may cause serious consequences. The most common** blockage of cerebral blood vessels is atherosclerosis. Hello, the patient has cerebral infarction and needs to go to a regular hospital for **, and the vascular stent can be placed as soon as possible after angiography.

Advice: It is recommended not to be overworked, rest more, and do not do strenuous exercise. Keep a good attitude and don't get angry. Eat more fruits and vegetables.

Most patients have myocardial infarction due to coronary artery stenosis and blockage. When there is atheroma formation in the coronary arteries, if the plaques are unstable or ruptured, they may cause local thrombosis, causing blockage of the coronary arteries, resulting in avascular necrosis of the myocardium in the local blood supply area. Whether myocardial infarction is better with drugs or surgery should be judged according to the condition of myocardial infarction.

1. Acute ST-segment elevation myocardial infarction, in this case, if in the early stage of the disease, emergency surgery** is the most ideal means, emergency surgery** can open the blocked coronary artery as soon as possible, save the surviving myocardium, protect the heart function to the greatest extent, and reduce the risk of heart failure and sudden death caused by myocardial infarction. Clause.

2. Acute non-ST-segment elevation myocardial infarction, in this case, if the GRACE score of myocardial infarction belongs to the high-risk group, timely surgery**, timely surgery**, can bring the greatest cardiovascular protection to the patient. Clause.

3. In the chronic stage of myocardial infarction, in this case, if there is no viable myocardium in the infarct area assessed by imaging examination, it is enough to conservatively treat the drug, and surgery often cannot bring benefits to the patient.

Myocardial infarction is the blockage of blood vessels, which is caused by the blockage of the blood vessels of the heart, so because of the poor blood flow, the heart will have an infarction at this time, so the myocardial infarction is very terrible, unlike the cerebral infarction and other infarctions.

The most insidious killer in the thrombosis.

If the road is blocked, traffic is paralyzed; If the blood vessels are clogged, the results can be fatal. In this long river of life, there is the blood on which human beings depend. Blood clots, like ghosts wandering in blood vessels, pose a serious threat to people's health anytime and anywhere.

According to statistics, deaths caused by thrombotic diseases have accounted for 51% of the global deaths, far exceeding the deaths caused by tumors, infectious diseases, and respiratory diseases.

A silent killer hidden in the veins.

All the blood vessels in the human body can reach a length of 10,000 kilometers and can circle the earth's equator more than twice. A thrombosis is a "blood clot" that forms in a blood vessel.

Article**2 Under normal conditions, blood clots in the body will naturally decompose, but with age, sedentary inactivity, life stress and other reasons, the human body will decompose blood clots slowly. Once a blood clot does not break down smoothly, it will accumulate in the walls of the blood vessels and is likely to move with the blood flow.

In general, thrombotic disorders can be divided into two types:

One is arterial thromboembolism. This type of blood clot is a blood clot that blocks an artery.

Cerebrovascular thrombosis may cause dysfunction of one limb, such as hemiplegia, aphasia, visual and sensory disturbances, coma, and in the most severe cases, disabling or fatal.

The other is venous thromboembolism. This type of blood clot is a blood clot that is blocked in a vein.

Venous thrombosis mainly affects the veins of the lower extremities, of which venous thrombosis of the lower extremities is the most common. The most terrible thing is that deep vein thrombosis of the lower extremities may lead to pulmonary embolism, and more than 60% of pulmonary embolic emboli in clinical practice** are in the deep vein thrombosis of the lower extremities.

Article**3 Thrombosis is the easiest to "tie" to five types of people.

1.People with high blood pressure.

2.Genetic populations.

3.Obese people with diabetes.

4.People with unhealthy lifestyles.

5.People who do not move for a long time.

Article **4 Stay away from blood clots, keep in mind the three-word decision.

Everyone in life should have a "thrombo-proof awareness". High-risk groups should do a good job of long-term prevention, take the initiative to go for deep vein thrombosis examination, and those with low risk factors can take general preventive measures.

Exercise more, drink more water, hook your feet, eat less oil, drink more tea, drink less alcohol, and loosen your shoes and socks.

Department of Neurology, Miao Mengjun).

Nothing happens without reason, it is a gradual process, especially for some chronic diseases, it may take a year or even many years to develop.

Although the development is slow, the induced diseases are generally not completely **, so they are more dangerous than some emergencies.

Here's a look at the progression of a patient who nearly lost his life to a heart attack.

First of all, the patient has been diagnosed with hyperlipidemia and hypertension, but why did he induce a heart attack? Look at the mistakes he made.

1. Mistakes were made

After being diagnosed, the doctor prescribed relevant ** drugs, and at the beginning, because the patient was still in a relatively nervous stage, he would take the medicine regularly and quantitatively every day.

During a follow-up examination, he learned that his blood pressure and blood lipids had dropped, so he stopped taking the medication without the permission of the doctor.

And in later life, when blood pressure rises, I will remember to take medicine, so this intermittent ** also lays the groundwork for the occurrence of myocardial infarction in the future.

2. Mistakes made in eating

For this patient, he has always maintained an unhealthy diet, he likes to eat salty meals, likes to eat foods that are high in oil, and these eating habits are indispensable at all times. Although his family often reminded him repeatedly, he never changed.

And such a diet is tantamount to increasing the severity of hyperlipidemia, which leads to an increase in the viscosity of blood vessels, which adds to the formation of blood clots.

3. Mistakes made in living habits

On weekdays, patients spend most of their time in the office, and because their work is relatively relaxed, their daily routines are not very good.

And his family has mobilized the patient many times to pay more attention to exercise on weekdays, and he doesn't care very much, even if he pulls out the exercise, it is only a symbolic walk of a few steps, and it is over.

It is important to know that reasonable exercise is very helpful for the consumption of blood lipids in the body, as long as the blood lipids are reduced, then the influence of blood vessels will be removed, and the natural blood pressure can be stabilized.

But it's such a simple truth, and patients don't stick to it.

Fourth, the mistakes made by erroneous thoughts

It's okay if he doesn't control his diet, doesn't take medicine on time, doesn't exercise, etc., but he doesn't know what he's heard from**special**, it is said that he can live without medicine and injections, and how he lived before and how he lives now. Just buy their instrument and wear it every day.

He really believed in these deceptions that ordinary people could see through at a glance, which also provided a favorable excuse for not cooperating in the future, but these things cost money and delayed.

The patient lived in the above way during the years when he was diagnosed with hypertension and hyperlipidemia. The final result was the occurrence of a heart attack, and although it was pulled back to the line of death after timely rescue, the lesson was very profound. Hopefully, this case will alert people suffering from cardiovascular disease.

The most important thing in cardiovascular and cerebrovascular diseases is to eat some junk food every day, and then if it goes on like this for a long time, some garbage will accumulate in the blood vessels little by little, and with the loss of time, the blood will slowly become very viscous, and in this case it will be blocked.

Usually eating habits are particularly bad, always eat some greasy food, especially like to smoke and drink, sleep very late at night, these habits will cause blood vessel blockage, usually must have a good living habits.

Because the cells in the blood vessels are not able to flow smoothly, and then they are clogged together, the blockage will become more and more serious over time

Cerebral infarction is also known as cerebral infarction. For patients with cerebral infarction, they should be hospitalized promptly for comprehensive**, both general and special**. Generally** refers to maintaining the patency of the respiratory tract, inhaling oxygen, regulating blood pressure, regulating blood sugar, lowering intracranial pressure**, regulating lipids and stabilizing plaques**; For patients with dysphagia, prevention of aspiration pneumonia; Patients with febrile infection should be given anti-infection, and fever should be reduced if necessary**; If the patient has comorbid secondary seizures, antiepileptic drugs should be given**; Patients with electrolyte abnormalities should be promptly corrected.

Special** mainly refers to if the patient's onset time is within an hour or 6 hours, thrombolysis should be given**, and antiplatelet aggregation can be given as soon as possible beyond the thrombolysis** time window, which can improve brain metabolism, fiber reduction and neuroprotection, etc., and butylphthalide and traditional Chinese medicine can also be given**. If the patient has concomitant physical symptoms and signs, ** training should be given as soon as possible to reduce the disability and mortality rate of the patient.

Myocardial infarction refers to the avascular necrosis of the myocardium, which is the reduction or interruption of blood flow in the coronary arteries on the basis of coronary artery lesions of the heart, so that the corresponding myocardium has severe and long-lasting acute ischemia, and eventually leads to avascular necrosis of the myocardium. The cause of infarction is mostly coronary atherosclerotic plaque or thrombosis on this basis, resulting in blockage of the lumen of the blood vessels.

In the lumen of the heart or blood vessels of a living body, the process in which blood clotting or some formed components in the blood stick to each other to form a solid mass, which is called thrombosis. In the physiological state, the coagulation factors in the blood are constantly activated, thrombin, and trace amounts of fibrin are formed, which are deposited on the intima of blood vessels, but these fibrins are constantly dissolved by the activated fibrinolytic system, and the activated coagulation factors are also constantly engulfed by the mononuclear phagocytic cell system. When the body is in certain pathologies, the homeostasis of the coagulation system and the fibrinolytic system is broken, triggering the coagulation process and forming a blood clot.

Over time, the lumen of the blood vessels will be blocked, and myocardial infarction will occur.
