Greek singer Giorgos Mazonakis dies at 54 after cardiac arrest

Popular Greek singer Giorgos Mazonakis passed away on Wednesday, September 9, 2026, at the age of 54, following a cardiac arrest during a medical procedure. The incident occurred at a private clinic in the Kolonaki area of Athens, where the artist had arrived for plasmapheresis treatment intended to improve his health ahead of a planned anniversary concert celebrating his 33-year career. Police, prosecutors, and the Medical Association of Athens are currently investigating the facility to verify its operating licenses and the legality of the procedures performed.

Following the tragedy, authorities conducted inspections at the clinic, which Minister of Health Adonis Georgiadis labeled as an "alleged clinic." Two doctors associated with the practice provided testimony to the authorities and were released. The forensic examination of the singer's body, originally scheduled for Thursday, was postponed until Friday, September 11, following the family’s decision to appoint a technical consultant. The death has prompted widespread mourning among fans and fellow artists, as investigations into the medical circumstances surrounding his sudden collapse remain in full progress.
