A man with a heart condition which meant a sudden shock could kill him died after a blow to the head, an inquest heard.

Paul Brannan, 48, who lived with friends in a flat at Rochester Street, Windhill, Shipley, had various DJ jobs when he was younger but was not working when he died in January 2007 due to ill health, the hearing at Bradford Coroner's Court was told.

Forensic Pathologist Dr Alfredo Walker, who carried out a post mortem, said that Mr Brannan suffered from a heart disease which meant that his arteries were narrowed which affected the supply of oxygen to the heart.

He said: "The physical stress from the head injury consistent with a blow to the head made a more than minimal contribution to the thrombosis (clotting) which led to his death." He concluded that the cause of death was acute cardiac artery thrombosis.

Mr Brannan's house-mate Lee Dawson said that Elaine Stevens, who had previously lived in the flat and had been thrown out by Mr Brannan two weeks before his death on January 28, 2007, had turned up with her sister Katherine Barker the night before he died.

Mr Dawson told the inquest that he went to a friend's house. Worried about Mr Brannan, they returned to the house a few hours later. He said Mr Brannan was clutching his chest and had blood on his T-shirt but refused an ambulance.

Mr Dawson and Mr Dores returned to the house together at 6.30pm on Sunday and found Mr Brannan dead.

Taxi driver Amjad Rehman picked up three women and a man from Rochester Street on Sunday morning at around 8.30am.

He said: "They were saying someone tried to attack them. One of them said she hit him with a bottle so hard he couldn't get up."

Mr Rehman could not confirm that the people in the taxi were present at yesterday's hearing.

Katherine Barker, Elaine Stevens and Shawner Lee Kenny will give evidence today when the inquest continues and is expected to conclude.
