The Argentina icon, who was the manager of Argentinian club side Gimnasia passed away aged 60 on Wednesday, November 25, after suffering a cardiac arrest in his home country.
An autopsy report leaked to Argentine media said he died in his sleep after suffering heart failure, only two weeks after leaving hospital following surgery to remove a blood clot on his brain.
Medics also detected dilated cardiomyopathy, a medical condition in which the heart muscle becomes weakened and enlarged and cannot pump enough blood to the rest of the body.
His nephew, Johnny Esposito was the last person to see him alive, according to the report, before doctors who had an appointment to see him went to his estate on Wednesday and found him unresponsive.
His last words before he died were: “I don’t feel well.”
Esposito said Maradona complained that he didn’t feel well after having breakfast on Wednesday before returning to bed in the Buenos Aires mansion.
As a crowd of weeping fans gathered outside the presidential palace on Thursday morning, Maradona’s coffin was lifted out of an ambulance and brought into the palace where it will lie in state for three-day national mourning declared by the Argentinian president Alberto Fernandez.
Some fans were also pictured outside the Buenos Aires stadium where Maradona began his career setting up a makeshift shrine to celebrate Argentina’s legendary number 10.
Maradona, regarded as one of the greatest footballers of all time, was the inspiration for Argentina’s World Cup success in Mexico in 1986, winning the Golden Ball as the tournament’s best player.
He also led the country to the final of the 1990 tournament in Italy although his international playing career ended in shame when he failed a drug test at the 1994 World Cup in the United States.
He played club football for Boca Juniors, Napoli, and Barcelona among others, and was adored by millions of fans for his football talent.
During his time with Italian side Napoli, he won the Serie A title in 1987 and 1990, along with an Italian Cup in 1987 and a Uefa Cup in 1991.
In 1999 and 2000 he was taken to hospital suffering heart problems, the second time requiring a respirator to breathe.
In 2004, he was again treated in hospital for severe heart and respiratory problems linked to his drug abuse.
He underwent two gastric bypass operations to control his weight and received treatment for alcohol abuse.
In January, he had surgery to stem bleeding in his stomach, and in July he underwent a knee operation.
