How long it takes to get out of bed after cardiac imaging is mainly based on the site where the patient is having the imaging. If it is the radial artery access cardiography, patients can get out of bed immediately after the operation, postoperative observation of the wrist for 6 hours, there is no great impact on the activities on the ground. If the cardiogram is done via the femoral artery, the patient will need to apply compression to stop the bleeding for about 24 hours, and will need to lie down and rest in bed after the procedure. If the coronary artery stenosis is very severe and further stenting is needed, the time to get out of bed depends on the patient’s recovery time after the procedure. Patients need to pay attention to drink more water after cardiac imaging to promote urination, which is conducive to the excretion of contrast medium, in order to avoid damage to the kidneys caused by contrast medium.
