Cardiac stent surgery usually requires hospitalization for 3~5 days, and the length of hospitalization is related to the patient’s recovery. Cardiac stent surgery is a minimally invasive surgical method, in which a stent is implanted into a narrowed blood vessel through a vascular puncture to open up the wall of the narrowed blood vessel, so that the blood vessel will be restored to smoothness. After cardiac stent surgery, the patient’s vital signs should be closely observed, including respiration, blood pressure and pulse, and the puncture site should also be observed to see if there is any bleeding or hematoma. Bed rest should be the main focus for 24 hours after the surgery, and the patient can be discharged from the hospital after three days when he recovers better; if the patient himself has underlying diseases, including diabetes, the wound site may recover more slowly, so the time of emergence will be relatively longer. After cardiac stent surgery, patients should take medication on time under the guidance of the doctor, and should also go to the hospital for regular review.
