How long you need to recuperate before you can go to work depends on the part of the patient where the imaging is performed and the severity of the disease, and should be analyzed in detail. If the cardiac imaging is done through the radial artery, it is enough to observe the wrist for 6 hours after the operation, and the patient can go to work the next day after the cardiac imaging, which basically has no effect. If it is the cardiac imaging via femoral artery approach, patients need to rest in bed after the operation, compression to stop bleeding for about 24 hours, patients can go to work after a few days of rest according to their own physical condition. However, if the condition is serious and further stenting is needed after the operation, the rest time will be extended according to the patient’s recovery. Before and after cardiography, patients should drink more water, which is conducive to the excretion of contrast medium and reduces the burden on the kidneys. At the same time, they should quit smoking and drinking, and avoid eating too greasy food.
