To begin with it appeared Astori, 31 at the time of his passing, had died from bradycardia, which is where the heart rate slows down to the point it stops.
However, the autopsy recently revealed it was tachycardia, which is where the heart rate accelerates beyond the normal rate. The new revelation makes the situation even more tragic, as it means there was a chance he could have been saved had he been sharing a room as he would likely have woken up.
And now, various reports in Italy are claiming the Udine public prosecutors have discovered a pre-existing heart condition, which was never found.
The central defender was a former Italy international, who also played for Roma before being named Fiorentina captain.
His No13 shirt has been retired by both La Viola and former club Cagliari.
