Blood vessel blockage is a very serious disease, and sometimes the blockage is so acute that there is no time to send out a signal, for example, we always hear about the sudden death of middle-aged people.

The most important cause of sudden death is heart disease, and the most important cause of heart disease is blockage of blood vessels in the heart, which is also known as acute myocardial infarction. So this part of the blood vessel blockage sometimes no signal, directly lead to cardiac arrest.

Of course, not part of the blocked blood vessels will have some signals, but because there are blood vessels all over the body, each part of the blocked blood vessels, give different signals.

Currently, the most common and dangerous blood vessel blockages include: heart blood vessels, carotid arteries, cerebral blood vessels, pulmonary arteries, lower limb arteries and other arterial blockages. If it is a chronic occlusion, sometimes there may not be any symptoms , but for acute vascular blockage, most of them have some signals.

We explain one by one:

The heart arterial vascular blockage signal

Heart arterial stenosis more than 50% called coronary heart disease, stenosis more than 70% may have symptoms, when the blockage 99-100% is myocardial infarction.

When the heart blood vessels are heavily narrowed, angina pectoris occurs, and often sends out a variety of angina pectoris signals: anterior heart area pain, chest pain, toothache, headache, pharyngeal constriction, back pain, shoulder pain, epigastric pain, chest pain, breath holding and other signals. These signals occur for about 2-15 minutes at a time, most often after activity, and can be gradually relieved after rest.

If it is an acute occlusion of the heart artery, that is acute myocardial infarction, then the most typical manifestation is the unremitting pressure-like persistent pain behind the sternum, accompanied by chest tightness and breath-holding, accompanied by profuse sweating. The atypical signals are the various angina pectoris persistent unrelieved is the signal of myocardial infarction. The most serious is fainting and sudden death.

The diagnosis can be confirmed by these signals plus electrocardiogram and cardiac enzymes, and it is necessary to immediately open the blood vessels through thrombolysis or stenting in order to save the life.

Carotid artery blockage signals

Severe stenosis of carotid artery may appear dizziness, lightheadedness, tinnitus, memory loss, blurred vision, insomnia, dreamy; vision loss, hemianopsia, dark twilight; transient aphasia, hemiparesis, hemianopsia, and so on. When the carotid artery is completely and acutely blocked, it will lead to cerebral infarction, then the sign of cerebral infarction appears.

Carotid ultrasound can be used to confirm the diagnosis, and after the diagnosis, medication or surgery can be chosen according to the specific situation.

Signal of cerebrovascular blockage

Cerebrovascular blockage is cerebral infarction, there may be a crooked mouth and eyes, aphasia, hemiplegia, hemiplegia, dizziness, headache, numbness of limbs, numbness of one side of the face or hands and feet, some for the numbness of the tongue, numbness of the lips, or numbness of the upper and lower limbs on the one side, suddenly one side of the limbs or inflexible activities, walking skewed, walking unsteadily, slurring of the words, the question is not answered, nausea, vomiting, or eructation, facial paralysis and tongue palsy, hemiplegia, choking and coughing when drinking water, Difficulty in swallowing, loss of consciousness, mental retardation, lethargy, and so on, even leading to death.

The diagnosis can be confirmed by brain CT or nuclear magnetic resonance, and thrombolytic or thrombolytic treatment is needed immediately after the diagnosis.

Signs of pulmonary artery blockage

It is also known as pulmonary embolism, after the occurrence of pulmonary embolism, it can also lead to sudden death, the common typical performance is dyspnea, chest tightness and breathlessness, chest pain, low blood pressure, fast heart rate, blackness in front of the eyes, fainting, fainting, pallor, cold sweating, coughing and so on, or anxiety, lethargy, nausea, convulsions and coma and so on signals.

Can be diagnosed by these signals plus electrocardiogram or D2 polymorphism, through the enhanced chest pulmonary vascular CT or imaging to confirm the diagnosis, after the diagnosis according to the specific circumstances, the choice of thrombolytic or anticoagulant therapy.

V. Signal of lower limb artery blockage

Intermittent claudication is the most typical signal of arterial blockage in the lower limbs. Intermittent claudication refers to the sudden appearance of unilateral or bilateral lumbago and leg pain, numbness and weakness of the lower limbs when walking, but it is fine after resting for a while, and then the same symptom will still appear after walking for a while. Of course, the lower limbs may also appear cold, pain, discoloration, local arterial fluctuations disappear.

The diagnosis can be confirmed by ultrasound of thrombus in the lower limbs, and after the diagnosis, treatment such as thrombolysis or anticoagulation can be taken.

We are talking about these common blood vessel blockage, are arterial blood vessels, veins can also occur blockage, such as lower extremity venous thrombosis.

Lower extremity venous thrombosis

Blood clots are formed in the lumen of veins due to various reasons, that is, the blood flow in the deep vein vessels is not smooth and clots are formed, which will block the blood vessels. After the occurrence of DVT, about 50-75% have clear risk factors. Surgery, trauma, bed rest, tumor treatment (hormonal, chemotherapy or radiation), advanced age, heart or respiratory failure, nephrotic syndrome, obesity, smoking, varicose veins, hereditary or acquired tendency to thrombosis, etc., which are often strongly associated with DVT, can lead to DVT.

The biggest danger of DVT is that once the thrombus is dislodged, it can run with the blood flow to the pulmonary vessels, causing blockage and leading to pulmonary embolism. Acute and severe pulmonary embolism has a mortality rate of up to 15% and can even lead to sudden death, which shows the great danger of DVT!

That is, the pulmonary embolism we mentioned above is actually caused by the dislodgment of blood clots after the formation of venous thrombosis.

In short, different parts of the blood vessel blockage signals are different, but most of the time when the signal is issued, it means that the blood vessel is heavily narrowed, or has been completely blocked, only emergency.

But most arterial blockage is caused by atherosclerosis, so atherosclerosis is the earliest signal of blood vessel blockage, but this signal is silent. We can’t feel it, we only know that high blood pressure, diabetes, high blood fat, smoking, alcoholism, sedentary and not exercising, obesity, unhealthy diet, staying up late, bad mood and so on are the root cause of atherosclerosis.

So, the three highs and unhealthy lifestyle are the earliest signals of clogged blood vessels!
