Prince Philip Resumes Royal Engagements Queen Elizabeth II's husband has returned to official duties following a heart procedure that saw him spend Christmas in hospital. Prince Philip was admitted to hospital with chest pains just before the holidays and underwent a successful coronary stent procedure. The 90-year-old was soon back on his feet, however, pictured walking to join the rest of the royal family in attending their traditional New Year's Day church service. Philip attended a fundraising dinner at Cambridge University Tuesday to support its Scott Polar Research Institute - his first official engagement since the heart scare. The prince, wearing a dark suit, joined other guests including Prince Albert of Monaco at the event supporting polar exploration.
