Former President Ford underwent his second heart procedure in a week at the Mayo Clinic in Minnesota.
Stents were placed into two of his coronary arteries to increase blood flow, his spokeswoman Penny Circle said Friday.
The angioplasty procedure on the 93-year-old Ford was successful, and he was resting comfortably in his room at the hospital in Rochester, Circle said in a statement.
On Monday, doctors at the clinic had fitted Ford with an implantable cardiac pacemaker to regulate his heartbeat.
Mayo Clinic spokesman John Murphy confirmed the procedure but would not comment further.
