The recovery time after cardiac imaging is largely dependent on the vascular approach and usually ranges from 6 to 24 hours. Most patients currently undergoing cardiac angiography with radial artery access can be on the floor after the procedure and are essentially uneventful. However, the removal of the radial artery compression device takes about 6 hours, during which time the puncture site should be closely monitored for bleeding and hematoma. For some patients with other problems with the radial artery, a cardiogram with a femoral approach may be performed. The patient needs to rest in bed after the procedure, and the compression will stop bleeding for about 24 hours, when the patient’s activity is slightly limited. 24 hours later, after the compression device is removed, the patient is mostly able to move freely. In the case of critically ill patients, although the angiogram is completed, close attention is still required due to the severity of the underlying lesion. The cardiac angiogram itself has less impact on the person, and patients are advised to actively cooperate with their doctors in their treatment, quit smoking and drinking in their daily life, and avoid overly oily food.
