Coronary angiography is a minimally invasive interventional procedure that usually recovers well in about 1 week. Coronary angiography, clinically known as coronary angiography, is performed through the radial artery or femoral artery, entering the body through a guidewire, sending the coronary angiography catheter to the opening of the coronary artery under the guidance of the guidewire, injecting the contrast agent through the coronary catheter, and observing the degree of coronary stenosis under the contrast image, which is the “gold standard” for clinical diagnosis of coronary heart disease. If the coronary stenosis is greater than 70%, it indicates the presence of coronary heart disease; if the coronary stenosis is greater than 75%, heart stenting is needed in time. Usually, the coronary angiography should be absolutely bedridden for 24 hours after the procedure, avoiding bed activities, and basically recovering in about 1 week. After coronary angiography, we need to pay attention to change the medicine to prevent infection at the wound, regularly review the electrocardiogram, cardiac enzymes, cardiac ultrasound, etc., pay attention to a light diet, regular work and rest, and refrain from smoking and alcohol.
