Peta Hickey had no medical history of cardiac problems she was invited to take part in a Cardiac Health Assessment by her employer, Programmed in March, 2019.
On May 1 that year, the 43-year-old mother went to Future Medical Imaging Group in Moonee Ponds for the scan.
Contrast Dye was administered intravenously and a scan was performed.
Shortly after, she began vomiting and losing consciousness.
A radiologist, Dr Gavin Tseng, was called back into the room and treated her, administering medicine but not adrenaline and asked for an ambulance to be called.
There she experienced complications and had her right leg amputated.
She never regained consciousness and died eight days later.
Ms Hickey left behind her partner Richard and two young children.
The coroner will investigate what information the radiologist had about Ms Hickey before the scan.
The court heard the push to provide employees with cardiac checks came after a senior executive at Ms Hickey’s workplace suffered a heart attack while on an overseas trip.
Chris Sutherland, who was the Managing Director of Programmed at the time, said he never directly received any medical advice about the appropriateness of that particular test for someone with no symptoms of heart issues.
The inquest is expected to run for three weeks.
