A mother-of-two who died while waiting for an ambulance was "let down" by the NHS, her brother has said.

Julie Hurn died two years ago after suffering a heart attack in her Attleborough home - almost two-and-a-half hours after first calling 999 over chest pains.

An inquest into her death resumed on Monday, in a hearing which is scheduled to last four days.

It heard that a swifter response to her initial call would have made a "significant difference" to her chances of survival.

The court heard 43-year-old Mrs Hurn had originally called for an ambulance at 3.26pm complaining of chest pains, with her call given category 2 priority - which comes with an 18-minute response target.

An hour later, she rang again to say she had begun vomiting.

But it was not until 4.53pm, when a neighbour who had come to her aid phoned again to say she was in cardiac arrest, that the call was upgraded - with paramedics arriving at 5.14pm.

Mrs Hurn, who worked as a contracts manager for Norfolk County Council, died at 5.48pm, 142 minutes after her first call to emergency services.

Rajesh Logasundaram, who carried out a post mortem examination of her body, said: "An earlier 999 call would have made a significant difference to her chances of survival."

Prof Saul Myerson, a consultant cardiologist based at the University of Oxford, also said a faster response would have improved her chances.

He said that while was unlikely her heart attack would have been prevented, had she been in hospital when it occurred her survival chances would have been better.

In a statement read to Norfolk Coroner's Court, her brother Gary Hambling said: "As a family we believe the NHS has let us down.

"The time taken to get an ambulance to her was unacceptable."

The inquest continues.
