Kanye West's mother she suffered a heart attack, coroner's report says

The final coroner's report into the death of rap superstar Kanye West's late mother following plastic surgery says she suffered a heart attack, it was reported last night.

But the Los Angeles County Coroner could not determine exactly what killed Donda West, according to website TMZ.

Ex-university professor Donda died a day after undergoing liposuction and a breast reduction.

But the coroner's report indicates the manner of her death "could not be determined", TMZ says.

It reportedly says several factors could have played part, but there was no evidence anesthesia caused or contributed to the tragedy.

Kanye was devastated by Donda's shock death on November 10.

It later emerged surgeon Dr Jan Adams was not board certified in plastic surgery and faces accusations he botched operations on other women.

Dr Adams, who has appeared as an expert on numerous US talk shows, has denied any wrongdoing. He said there were no complications in Donda's procedure.

The surgeon said it was likely Donda died from a heart attack, a pulmonary embolism or an accidental overdose from drugs he had prescribed her for post-operation pain management.

No-one from the coroner's office was available to comment on the report yesterday.
