Dr. Yang, who just finished checking the room, received a WeChat from a patient. His tone was very serious and depressing, as if the sky were falling.

Dr. Yang remembers this patient, who had coronary angiography in his hand not long ago because of coronary artery stenosis.

At the time of the examination, Uncle Chen's coronary artery stenosis was more serious. He was afraid that there was something wrong with his body. Dr. Yang immediately made a video call and said, "What's your problem?"

"Dr. Yang, I have heard that people who have undergone coronary angiography will not live long. I always feel stuffy in my chest recently, and I am dying."

Like Uncle Chen, many people who have had coronary angiography or are going to have coronary angiography will worry about this problem, but will coronary angiography affect their life expectancy?

To know whether coronary angiography will affect life expectancy, we must first know what coronary angiography is.

1. What is coronary angiography?

Coronary angiography is a common method to diagnose coronary heart disease. When doing coronary angiography, you need to put a catheter in the peripheral aorta, puncture the blood vessel through the skin and then insert a small catheter. Under the guidance of X-ray, the catheter is selectively sent to the opening of the left and right coronary arteries, and then contrast agent is injected. The morphological characteristics of coronary arteries can be displayed through X-ray perspective.

Under the action of contrast agent, the coronary artery can be developed, and the lesions of the coronary artery can be seen at a glance, and it is clear whether the coronary artery is narrow, and the degree and location of the stenosis can also be used to guide further treatment.

Coronary angiography can accurately and timely diagnose coronary heart disease, which is regarded as the "gold standard" and the only reliable standard for diagnosing coronary heart disease at home and abroad.

Some patients will be very resistant when they hear the doctor say that they want to have a coronary angiography. They think that this is a harmful examination to the human body, and even think that people who have had a coronary angiography will not live long. Is this true?

Second, people who do coronary angiography will not live long?

There are two main reasons why many people are worried about coronary angiography: first, because coronary angiography is an invasive operation, it is operated on the heart, so many patients will instinctively resist it; The second reason is that many people are not familiar with contrast media because they need to inject contrast media when doing coronary angiography, and they are worried that there will be radiation problems that will affect their health.

In fact, these two concerns are unnecessary.

Coronary angiography is a minimally invasive operation and a relatively safe operation. At present, it ranks first in the United States, and the average mortality rate of surgery is below 0. 1%.

Generally speaking, patients can bear this examination. Because there is no pain nerve in blood vessels and heart, local anesthesia is performed on the skin where the needle is inserted during coronary angiography, so the whole operation process is painless, and the operation time generally does not exceed 1 hour.

In the process of coronary angiography, the patient is awake, and once he feels unwell, he can tell the doctor in time so as to take corresponding measures. Coronary angiography has been used for nearly 60 years, and both the catheter material and technical operation are relatively perfect, which can be called a safe examination.

In addition, the contrast agent that worries patients has not reached the level of harm to the body. Although coronary angiography should be carried out under certain radiation conditions, there is radiation, but the dose of contrast agent is low, and the hospital also has corresponding protective measures, which will not cause personal injury to the patient himself.

Although there are not many complications of coronary angiography, some studies have found that 7% of suspected patients with coronary heart disease have slow blood flow during coronary angiography, which is relatively small.

Third, coronary angiography is suitable for most people, but don't try it easily for three people.

Although coronary angiography is suitable for most patients, there are three kinds of people who should not try it easily. First of all, people who are allergic to iodine should not do coronary angiography. If iodine allergy is only a mild rash, coronary angiography can be done on the premise of using hormones or using nonionic contrast agents.

Secondly, people with hyperthyroidism should not do coronary angiography, because hyperthyroidism also needs iodine for treatment, so it is not suitable to do coronary angiography, which may be unfavorable to the condition;

Finally, because coronary angiography will use contrast agent, which may have a certain impact on the kidney, people with severe renal insufficiency are not suitable for coronary angiography.

4. What is the difference between coronary CT and coronary angiography?

In addition to coronary angiography, coronary CT is also a kind of examination that we often hear. Both coronary CT and coronary angiography are commonly used methods to diagnose coronary heart disease. What's the difference between these two tests?

First of all, the accuracy of the two is different, and the results of coronary angiography are more accurate;

Secondly, coronary angiography is an interventional examination, which is invasive, while coronary CT is a non-invasive examination, and the patient's pain is relatively small and easy to accept;

Finally, coronary CT is only an imaging examination, but if the patient's lesions are found to be serious during coronary angiography, stent surgery can be directly performed.

It seems that coronary angiography is not as terrible as expected. If the doctor suggests it, it is best to cooperate with the examination to avoid delaying the illness. #39 Health Super Group # # Breeze Plan #
