What are the hazards of coronary angiography to human body? Can you live longer after coronary angiography?

Coronary angiography has no harm to human body, and the life span will not be affected after coronary angiography.

Coronary angiography is not too harmful to the body. Although coronary angiography is a minimally invasive examination method, it needs puncture, but the puncture site will gradually heal after a few days, which is basically harmless to the body. Even if X-ray is needed, it will not have much impact on the body. However, there may be some damage in the comparative examination.

For example, it can cause iodine allergy in patients, but this situation is relatively rare. It is necessary to carry out systematic examination before angiography, and patients should also strengthen nursing work after angiography. In particular, drinking more water can promote the excretion of contrast media. And pay attention to whether there is hematoma or bleeding at the puncture site after angiography.

Coronary angiography is a common and effective method to diagnose coronary atherosclerotic heart disease, and it is a relatively safe and reliable invasive diagnostic technique. It has been widely used in clinic and is considered as the gold standard for diagnosing coronary heart disease. The main function of coronary angiography is to evaluate the course, quantity and deformity of coronary arteries.

To evaluate the existence, severity and scope of coronary artery disease; To evaluate the changes of coronary artery function, including coronary artery spasm and collateral circulation; At the same time, it can give consideration to the evaluation of left ventricular function. On this basis, interventional therapy can be carried out according to the degree and scope of coronary artery lesions; To evaluate the effect of coronary artery bypass grafting and interventional therapy; Long-term follow-up and prognosis evaluation can be carried out.

The time of coronary angiography is related to the time of coronary artery stenosis, the difficulty of operation, the proficiency of doctors and many other factors. The time of coronary angiography is generally 10-20 minutes, and some people may need longer time. Generally, they need to do two blood vessels, left coronary artery and right coronary artery, to see the degree of stenosis.

First of all, skin test and iodine contrast allergy test should be done before angiography to see if there are any allergic symptoms. If you are allergic to iodine, coronary angiography will not show it. Angiography is usually performed under local anesthesia, and puncture is performed through the right radial artery. If the puncture is successful, coronary angioplasty can be completed through the right upper limb. If not, coronary angiography is usually performed through the femoral artery of the lower extremity.
