In a Facebook post shared on Di’Anno’s official page, a statement from his representatives read, "Dear fans and friends, We have received permission from Paul's family to bring you the news of Paul's cause of death, after the results of the autopsy have been received."

According to the statement, Di’Anno’s sisters Cheryl and Michelle confirmed their brother "had a tear in the sac around the heart and blood has filled inside it from the main aorta artery and that has caused the heart to stop."

The singer began experiencing health issues in the 2010s, including knee surgery in 2014 that often had him performing live shows in a wheelchair. He also had a cancer scare.

He told Classic Rock, "I collapsed at home after coming back from Argentina and a scan found a massive big black shadow on my lungs. I thought I was on my way out, but it turned out to be non-malignant."

"It was an abscess that was all infected and the size of a rugby ball. It turns out I’ve been living with this thing in me for the last few years," Di’Anno said.

He added, "I suppose I’m pretty damn lucky, but the last six months have been hard."
