A RETIRED dentist died in hospital following surgery on his knee, an inquest was told.

Christopher Boyes attended the Royal Sussex County Hospital in Brighton for the procedure.

The 64-year-old, of Rose Walk, Worthing, had gone for the elective operation and his needs were assessed by doctors at the hospital.

Mr Boyes needed dialysis and was also diabetic, Brighton Coroner’s Court was told.

Coroner’s officer Arianna Palermo told the inquest that Mr Boyes’ operation had gone well but then while recovering he suffered a heart attack.

City pathologist Dr David Wright gave a provisional cause of death as cardiac arrest from hypertensive heart disease.

Haemodialysis and diabetes were also contributory factors, the pathologist said.

Coroner Veronica Hamilton-Deeley said doctors from the hospital would be required for Mr Boyes’ inquest on June 4.

Mr Boyes is survived by his wife, daughters, brother, nieces and nephews.
