Blood vessels are blocked, look at the ears? complexion? toe? Doctor's reminder: none of it is right, look here!

Blood vessels are the lifeblood of our human beings, blood vessels transport blood and oxygen.

Once a blood vessel is blocked, then there is ischemia, there is a lack of oxygen; persistent ischemia can lead to tissue necrosis.

Especially in such important departments as the heart, lungs, and brain, once the blood vessels are blocked, there will be myocardial infarction, lung infarction, and cerebral infarction, which will often bring fatal results.

So how do we judge whether the blood vessels are blocked or not?

Some people say that looking at the earlobe, the earlobe has a crease and the blood vessel is blocked.

Most of the myocardial infarction or cerebral infarction patients we rescue in the hospital do not have so-called earlobe creases. When a cardiovascular and cerebrovascular doctor diagnoses whether a person has a blood vessel blockage, he will never look at the earlobe crease. This was nothing more than a British view from 1973, but it wasn't really used in the clinic because it wasn't practical and had little value.

Some people say that looking at the face and the face is dark, it means that there is congestion and that the blood vessels are blocked.

This method has never been used clinically. When seeing a doctor, you will indeed look at the face, whether it is the hope of traditional medicine, or the sight in modern medicine, in fact, it is a medical treatment, and this look of course includes looking at the face. But no one can look at the face to see whether the blood vessels are blocked or not.

Some people say that looking at the fingers of the foot, the toes are numb, and the toes are cold, it means that the blood vessels are blocked.

There are many reasons for tingling or cold limbs, sometimes it is true that the limbs, especially the blood vessels in the lower limbs, are blocked, but this is at best a preliminary way to determine whether the blood vessels in the lower limbs are blocked, and it is not accurate.

Most critically, we are more concerned with the blood vessels of the heart, the blood vessels of the lungs and the blood vessels of the brain. Because the blood vessels in these three parts are often fatal, it is impossible to judge whether the blood vessels in these important parts are blocked by looking at the earlobes, faces, and lower limbs.

So as a cardiovascular doctor, how to judge whether the blood vessels in key parts are blocked or not?

First, the blood vessels of the heart are blocked

1. Completely blocked

The heart vessels are completely blocked, usually due to acute thrombosis, caused by acute myocardial infarction. Doctors diagnose myocardial infarction in three indicators: persistent symptoms of angina in patients, st.elevation or T-wave high-tip ECG in patients, and patients with proportionally elevated troponin or myocardial enzymes.

Among these 3 indicators, as long as two are met, acute myocardial infarction can be diagnosed, that is, the blood vessels of the heart are blocked.

2. Narrowness

A. Severe stenosis, generally more than 75% of the stenosis, at this time the patient may have symptoms of angina; the doctor will initially judge whether the patient's blood vessels have severe stenosis according to the performance of the patient's angina. At the same time, it can be combined with electrocardiogram and exercise test examination to assist in diagnosis. A more accurate approach is to do a coronary CT or coronary angiogram.

B. Moderate stenosis, but when the narrowing of heart vessels exceeds 50%, we call it coronary heart disease. If not more than 70% of people are asymptomatic, so it cannot be judged by symptoms. If further investigation is required, coronary CT or coronary angiography is performed under the guidance of a doctor if necessary.

C. Mild stenosis, less than 50% of the stenosis is generally called plaque, no symptoms, not called coronary heart disease. Theoretically, this needs to be known by coronary CT or contrast. But this level of plaque, generally no symptoms, there is no need for CT or contrast, control the three high healthy life on the line.

2. Pulmonary vascular blockage

Pulmonary vascular blockage, called pulmonary infarction is also called pulmonary embolism, this thrombus is not a blood clot of the lung blood vessels, but a blood clot in other parts of the body that falls down, runs to the lung blood vessels, and blocks the pulmonary blood vessels. For example, venous thrombosis of the lower extremities, amniotic fluid thrombus, tumor thrombus and so on.

Typical symptoms of pulmonary embolism: dyspnea, chest tightness, chest pain, hypotension, rapid heart rate, lack of oxygen, etc.

Combined with the performance of ECG S1Q3T3, as well as the comprehensive diagnosis of D-2 polymers, if necessary, CT of lung increase is confirmed.

3. Cerebral blood vessel blockage

When the cerebral blood vessels are completely blocked, that is, when the brain infarction occurs, most people will have symptoms: hemiplegia, aphasia, hemiplegia, asymmetry of limb strength, inaccurate speech expression, crooked mouth and eyes, skewed walking, and so on.

Diagnosis can be confirmed by ct or mroraco.

Because most of the blood vessels of cerebral infarction originate from the carotid arteries, it is usually possible to see if there are plaques in the blood vessels through carotid ultrasound, the size and nature of the plaques, and it is also helpful to judge the risk of future cerebral infarction.

There are also some cerebral infarctions caused by atrial fibrillation, so patients with atrial fibrillation are also prone to cerebral infarction.

In short, the whole body is covered with blood vessels, blood vessels in different parts are blocked, the symptoms are different, and the examination methods are different.

But it is certain that by looking at the ears, looking at the eyes, looking at the face, looking at the fingers of the feet, etc., it is impossible to judge whether the blood vessels are blocked or not. However, the causes of these blood vessel blockages are similar, and the blockage of cardiovascular and cerebrovascular vessels is basically caused by the aggravation of atherosclerosis.

Therefore, to prevent the aggravation of atherosclerosis is to prevent blood vessel blockage. Atherosclerosis is mainly caused by high blood pressure, diabetes, hyperlipidemia, obesity, excessive tobacco and alcohol, sedentary inactivity, unhealthy diet, staying up late, stress and so on.

Therefore, instead of discussing whether the blood vessels are blocked or not, it is better to do a good job of yourself, and prevention is the most important!
