(People) – Ozzy Osbourne‘s cause of death has been determined.

According to a death certificate obtained by The New York Times and The Sun, the legendary rock star died of “out of hospital cardiac arrest” and “acute myocardial infarction,” with coronary artery disease and Parkinson’s disease with autonomic dysfunction listed as “joint causes.” Per the Times, Osbourne’s daughter Aimee submitted the death certificate at a registry in London.

The Black Sabbath frontman and reality TV personality died on Tuesday, July 22. He was 76.

“It is with more sadness than mere words can convey that we have to report that our beloved Ozzy Osbourne has passed away this morning,” Osbourne’s family told PEOPLE in a statement at the time. “He was with his family and surrounded by love. We ask everyone to respect our family privacy at this time.”

After the rock god’s death, a Thames Valley Air Ambulance spokesperson confirmed to PEOPLE in a statement that its helicopter “was dispatched to provide advanced critical care at an incident near Chalfont St Giles on Tuesday 22nd July.” The Daily Mail first reported that the air ambulance was called to the Black Sabbath frontman’s family home and spent two hours providing care before the rock legend died.
