McQueen, the former enfant terrible of the British fashion world who went on to global commercial success with his provocative designs, was found dead at his central London home last Thursday, aged 40.
The designer -- full name Lee Alexander McQueen -- died from asphyxiation and hanging at his home in London's upmarket Mayfair district, according to a post mortem.
The results of the post mortem were presented at Westminster Coroners' Court, as an inquest into his death was opened.
"At about 10.30am last Thursday February 4, a man was found hanging in his wardrobe at Flat 1, Green Street, London, W1," said coroner's officer Lynda Martindill.
"On Monday February 15, he was identified as Lee Alexander McQueen, aged 40, born 17/3/69 in Lewisham, south east London. He was a single man, a fashion designer. He resided at Flat 1, 7 Green Street W1K."
Representing the police at the inquest, detective inspector Paul Armstrong, said that a "note" had been found at the scene, which he handed to the coroner for examination as part of the inquest.
From a humble background, McQueen rose to become one of Britain's most lauded fashion designers.
A four-time winner of the British designer of the year award, he designed for Givenchy and was creative director of his own label which was bought out by Gucci.
Media reports said McQueen's mother Joyce died on February 2, and in a comment on his Twitter page days before his death he wrote that he had had an "awful week."
McQueen's close friend and fashion icon Isabella Blow killed herself three years ago at the age of 48. Suffering from cancer and depression, she died after drinking weedkiller having told friends she was going out shopping.
Media reports immediately after his death suggested he had hanged himself, but police had so far declined to confirm the cause of death, saying only that it was not suspicious.
His death cast a cloud over New York Fashion week last week, and came days before models take to the catwalks here for the London version, ahead of shows in Paris and Milan.
Among the first tributes which poured in within minutes of his death was that of German couture legend Karl Lagerfeld, who told AFP: "There was always some attraction to death, his designs were sometimes dehumanised.
"Who knows, perhaps after flirting with death too often, death attracts you," he added.
On Tuesday night, flamboyant US superstar Lady Gaga paid an emotional tribute to him after scooping three awards at Britain's top music awards the Brits in London.
As she took the stage to play her song "Telephone", she told the audience: "This is for Alexander McQueen."
Sales of McQueen's clothes and accessories surged, as fashion fans rushed to grab mementos.
Top London store Liberty's said its stock "started flying off the shelves," while Selfridges department store said it had seen a "very significant and immediate uplift" in sales.
