George Michael died of natural causes as the result of heart disease and a fatty liver, a British coroner said today.
Darren Salter, senior coroner for the county of Oxfordshire in southern England, said a post-mortem has found that the singer died of "dilated cardiomyopathy with myocarditis and fatty liver."
Dilated cardiomyopathy is a condition in which the left ventricle of the heart becomes stretched and weakened, limiting the heart's ability to pump blood.
Myocarditis is inflammation of the heart muscle.
The former Wham! singer-songwriter was found dead at his country home in Oxfordshire on December 25, aged 53.
An initial autopsy failed to determine the cause of death for the star, who had battled health problems and drug addiction.
Salter said that because Michael died of natural causes, there will be no coroner's inquest or further inquiries.
In Britain, inquests are held to determine the facts of unexplained deaths.
Police initially investigated and took witness statements in order to establish the facts surrounding Michael's death, which they called "unexplained but non-suspicious."
The singer suffered problems with drugs and alcohol, however, and in 2010 was briefly jailed after crashing his Range Rover into a shop front near his London home while high on prescription drugs and marijuana.
Michael had experienced health problems including a bout of pneumonia in 2011 that saw him hospitalised in intensive care.
Michael's former partner, Kenny Goss, has said he thinks the musician's body "just gave up."
