The Duke of Edinburgh has opened a new £5.5 million Cardiac Centre at Luton and Dunstable University Hospital.
He took a guided tour of the building, where specialised staff will treat heart patients with a range of conditions.
Dr Christopher Travill, Consultant Cardiologist at Luton and Dunstable Hospital said:
The hospital says that the new centre will treat up to 700 patients each year. Local people have donated more than £41,000 in recent months to pay for additional medical equipment there.
Prince Philip is the third member of the Royal family to visit the hospital, which was opened by Queen Mary in 1939. More recently The Princess Royal opened the St Mary’s Wing for Therapies and Elderly Medicine in 2002.
