How is cardiac angiography performed? Why do we need to rest after the procedure?

If the patient has a simple cardiogram done from the radial artery in the wrist, and there are no major problems with the patient's blood vessels, then coronary heart disease can be ruled out, presumably after the electrocardiogram, the wrist artery can be Break it without being affected, naturally, and you can walk back to the ward. However, the wrist required compression and wrapping for more than six hours. During this period, bleeding should be prevented. After all, it is an arterial blood vessel. But if it is punctured from the leg, which is the femoral artery, then after radiography.

According to the latest news I learned, you cannot land on the ground, and you must lie flat at all times. You can only go to the ward by flat car. The most important thing is to worry about femoral artery bleeding. It takes 12-24 hours to return to the ward, and then you can go to the ground for activities. Of course, if a stent is placed after radiography, or if severe vascular disease develops, a wheelchair must be used back to the ward. Or if you need angiography for acute myocardial infarction, you can only take a flat car back to the ward.

To put it simply, we insert a flexible tube from the arterial blood vessel of the arm or thigh to the opening of the arterial blood vessel that delivers to the heart, and then inject some contrast agent, that is, the contrast agent, from this tube, At the same time, under X-ray irradiation, the blood vessels of the heart can develop, and we can clearly see the arteries and blood vessels of the heart on the display screen, whether they are stenotic or blocked, so as to determine whether there is coronary heart disease.

Generally speaking, stenosis less than 50% is called coronary atherosclerosis, and stenosis greater than 50% is called coronary heart disease. During the entire procedure of cardiac angiography, the patient is fully awake and no surgery is required. , which only requires a needle to wear a small eye over an artery in the thigh or arm to complete the procedure, the contrast procedure usually only takes about ten minutes, but if further stents are needed, it will take more time, but the entire method It's the same.

Finally, as for how cardiac angiography is done and why we need to rest after it, this is the end of our analysis today.
