Authorities are continuing to reconstruct the final hours of Greek singer Giorgos Mazonakis, who died after suffering cardiac arrest at a private medical practice in Athens’ Kolonaki district earlier this month, with new testimony and digital evidence adding to questions over the treatment he received and the response to his collapse.
The 56-year-old female doctor and her 58-year-old husband, who had responsibility for the practice, remain in custody at the Korydallos prison after being charged in connection with Mazonakis’ death. They deny wrongdoing.
The investigation is examining the legality of the plasmapheresis procedure, the circumstances surrounding the singer’s deterioration and the actions taken before emergency services were called.
According to information presented by Mega Channel’s Live News program, Mazonakis had undergone a colonic hydrotherapy at the same practice one day before the plasmapheresis procedure. He reportedly had reservations about undergoing plasmapheresis, but the doctor and a hypnotherapist with whom she worked persuaded him to proceed. He had also arranged to meet the hypnotherapist at 5 p.m. after the procedure, but the appointment never took place.
The timeline presented in the report begins on Monday, two days before Mazonakis’ death, when he met the hypnotherapist at a restaurant in the upscale Psychiko district after contacting him through a woman with whom he worked. The two subsequently arranged to meet on Wednesday afternoon and agreed that Mazonakis would undergo plasmapheresis at the doctor’s practice.
Mazonakis had known the doctor for years, having undergone hydrotherapy there in 2021. According to information presented in the investigation, he had expressed reservations about the plasmapheresis procedure before agreeing to undergo it.
On Wednesday, the singer arrived at the practice for the scheduled procedure. According to the latest account, the procedure began at 2:14 p.m., while the machine subsequently recorded alerts. Digital records and other evidence are being examined alongside security-camera footage, computers, mobile phones and other material seized during the investigation to reconstruct events minute by minute.
At about 3:22 p.m., a 53-year-old nurse reportedly noticed a movement in Mazonakis’ arm and alerted the doctor. The treatment was stopped at about 3:45 p.m. as the singer collapsed and confusion reportedly spread through the practice.
A further focus of the investigation is whether Mazonakis had been given sedation. A telephone call was made from the practice to an anesthesiologist shortly before EKAB was contacted. The caller reportedly said that a patient had been given sedation and its antidote and asked whether anything else could be administered. A clinic secretary has also said she heard the words “sedation,” “defibrillator” and “adrenaline” during the emergency.
The latest account raises further questions over what equipment and expertise were available to respond to the collapse, including whether staff knew how to use the defibrillator and whether appropriate respiratory support and medication were immediately available.
Authorities are also examining an allegation that the doctor sought assistance through an AI platform while Mazonakis was critically ill. That allegation remains unconfirmed.
The forensic examination found that Mazonakis had suffered myocardial ischemia but did not establish a definitive cause of death. Toxicological and histological tests are still pending and are expected to be crucial in determining what caused the ischemia and ultimately led to his death.
