The cause of Ray Liotta's death has been revealed, one year after the Goodfellas star died aged 67. 

The actor died from acute heart failure and respiratory issues, according to documents obtained by TMZ.

He died in his sleep, his representative Jennifer Allen said at the time.

He was in the Dominican Republic shooting a film called Dangerous Waters when he died.

Liotta was engaged to be married and his fiancée was with him as he worked on the project.

Doctors categorised the actor's death as "natural and non-violent", citing the causes as heart failure, respiratory insufficiency and pulmonary oedema - a build-up of fluid in the lungs.

The documents also said Liotta suffered from atherosclerosis, a build-up of fatty deposits in the arteries which causes them to narrow and increases the risk of heart attacks and strokes.

Liotta was best known for playing real-life mobster Henry Hill in the classic gangster movie Goodfellas in 1990.
