An inquest has been opened after a Barking man called Mr Lucky collapsed and died with a rare heart condition on his birthday.

Jakub Lucky, 45, of Portia Court, was described in court as a chronic drug user.

Paramedics called out to conduct a welfare check found him collapsed on the floor and determined he had suffered a sudden cardiac arrest.

An inquest was opened into his death at East London Coroner’s Court, Walthamstow, on Thursday, October 31.

Paramedics from the London Ambulance Service administered two shocks with a defibrillator, testified coroner’s officer Jean Smyth, leading to a “return of spontaneous circulation”.

Mr Lucky was transported to King George Hospital in Goodmayes, where he was intubated and placed in intensive care.

Upon admission, he was found to have a sternotomy scar, indicating recent chest surgery, and a subarachnoid haemorrhage – an uncommon type of stroke – on his right frontal lobe.

There was also a “large mass” on one of his heart valves, the court was told.

He was placed on renal blood filtration, to take over the job of his kidneys, but it persistently failed due to “unmanageable low blood pressure”, Mrs Smyth said.

A post-mortem examination on October 1 found Mr Lucky had died from “multi-organ failure related to an out-of-hospital cardiac arrest”.

He also had a rare heart infection called bacterial endocarditis, and related septicaemia.

Another contributory factor in his death, a pathologist ruled, was “chronic intravenous drug abuse”.

The final contributing factor was an “old myocardial infraction” – also known as a blood clot which blocks blood supply to the heart.

“I’m satisfied, on those facts, this death occurred in circumstances requiring an inquest,” said coroner Nadia Persaud.

Declaring Mr Lucky’s family interested persons – meaning they can interrogate evidence and question witnesses at the inquest – she asked them to supply “some general background information relating to Mr Lucky and, if they have any concerns surrounding his death, details of those concerns.”

She also ordered disclosure of Mr Lucky’s GP and hospital records, and any information held by any drug or alcohol services he may have been seen by.

His inquest was set for March 20.
