Patients are typically discharged from the hospital within 24 hours of undergoing angioplasty, notes Mayo Clinic. Heavy lifting and strenuous physical activity should be limited for one day following the procedure.
During angioplasty, a doctor inserts a thin tube into the artery, explains Mayo Clinic. Once the tube is in place, the doctor threads a catheter through the circulatory system until it reaches the narrowed artery. After injecting contrast material into the catheter, the doctor uses a balloon to widen the vessel. If necessary, a small tube made of mesh metal is inserted into the artery to prevent narrowing in the future. The patient must lie still for several hours after the procedure to prevent the site where the catheter was inserted from bleeding.
