What's going on with cardiography

summary

My father is 59 years old. During the Chinese new year, my father had chest tightness, dizziness and nausea several times. Such symptoms also appeared in 2009. The day before yesterday, I took my father to the hospital for examination. The doctor asked me to do B-ultrasound and exercise ECG. The B-ultrasound result said that there was arteriosclerosis, and exercise ECG said that the test was positive. The doctor can do cardiography. So, what's going on with cardiography?

What's going on with cardiography

The first aspect: cardiac angiography is to insert a very thin catheter into your aorta, and then inject contrast agent into the aortic blood through the small opening in front of the catheter, so that the X-ray can show the shape of blood vessels and heart in the display screen. The mixture of sodium salt and meglumine salt used in cardiography has certain toxicity, but little effect. Your dad needs a cardiogram.

The second aspect: cardiac angiography, that is, coronary angiography, belongs to the category of interventional therapy. It uses a hollow tube to send the coronary artery of the heart from the femoral artery or elbow artery along the artery, and then injects the contrast agent. The contrast agent can be displayed under the X-ray. Through the X-ray machine, we can see whether the coronary artery is in shape, whether it is blocked, and the range of blockage, the blood The stent can also be implanted at that time to increase the peripheral diameter of blood vessels and reduce the symptoms of angina pectoris.

The third aspect: cardiac angiography is to insert a very thin catheter into your aorta, and then inject contrast agent into the aortic blood through the small opening in front of the catheter, so that the X-ray can show the shape of blood vessels and heart in the display screen. The process of cardiac stent surgery is to puncture the blood vessel, make the catheter move forward in the blood vessel, reach the opening of coronary artery, use a special delivery system to transport the stent to the place where it needs to be placed, place and withdraw the catheter, and end the operation.
