A Glemsford man may have fallen and suffered a fatal head injury due to a heart condition, an inquest heard.
Peter Bowers, 66, was found at the bottom of the stairs at his home in Kings Road on March 27 by his partner of 35 years.
Before an ambulance arrived, Mr Bowers, a retired security officer, stopped breathing and had to be resuscitated by paramedics.
An inquest on Monday heard that Mr Bowers was taken to West Suffolk Hospital where a scan showed he had suffered a skull fracture and brain haemorrhage.
Despite the efforts of doctors, Mr Bowers died the following day. A post-mortem examination concluded that his death had been due to a traumatic head injury.
There was no indication that Mr Bowers, who had just returned from a party when the accident happened, had been under the influence of alcohol.
Suffolk coroner Dr Peter Dean said the post-mortem also showed that Mr Bowers was suffering from a heart condition which may have caused him to fall.
Dr Dean said that although this might provide an explanation for the fall, it was unclear what the actual cause had been.
He recorded a verdict of accidental death.
