Ex-Channel Nine boss David Gyngell smiles with his children in a photo taken before his heart attack - as his wife Leila McKinnon says he seemed 'super fit and healthy'
TV reporter Leila McKinnon has shared a photo of her husband, David Gyngell, looking 'super fit and healthy' just weeks before he almost died of a heart attack.
The 47-year-old journalist posted an image to Instagram of the former Channel Nine boss smiling with their children, and explained there had been no warning signs of what was to come.
Leila urged her fans to remain on top of their heart health, saying that David, 54, was lucky to be alive after having a 99 per cent blockage in his coronary artery.

David suffered a heart attack last week.
The media executive was rushed to hospital by Leila, after she noticed him looking 'a little grey' upon returning to their Byron Bay home following a boot camp session with tennis star Pat Rafter.
Friends told Sydney Morning Herald on Saturday that Leila's quick response had saved her husband's life.
'He came home from this super macho crazy boot camp with his mates looking a little grey and complaining of the classic heart attack symptoms, such as pressure on the chest and a tingly arm,' Leila said.

'I gave him the choice of an ambulance or hospital. He didn't put up much resistance so I knew he was worried too,' she added.
Doctors at Gold Coast's John Flynn Hospital inserted stents to improve blood flow, after discovering a significant blockage in two arteries.
David told The Courier Mail last week: 'If I hadn't been fit, I could have died.
'I was training like I do most days. Then I felt tired and a bit weird but still went to breakfast with the boys.'
