What happened before the Greek singer suffered a cardiac arrest, from the emergency call to his transfer to Elpis Hospital
The sudden death of beloved Greek singer at the age of 54 has sent shockwaves through Greece and the Greek community worldwide.
Mazonakis suffered a cardiac arrest on Wednesday afternoon, September 9, while at a private medical clinic in Kolonaki, Athens. Despite immediate resuscitation efforts and his subsequent transfer to Elpis Hospital, doctors were unable to save him.
The precise circumstances surrounding the singer’s final moments are now the subject of an investigation.
Mazonakis arrived at the Kolonaki clinic for scheduled treatment
According to information available so far, Mazonakis had visited the Stem Cell clinic on Karneadou Street in Kolonaki for a scheduled medical treatment.
He had reportedly attended an initial appointment the previous day, with the treatment planned for Wednesday.
During the visit, and according to preliminary reports, Mazonakis experienced severe chest pain before suffering cardiac arrest.
The exact medical circumstances remain unclear, and there is currently no published medical or forensic evidence establishing that the treatment, the insertion of an intravenous catheter or any specific medical procedure caused the cardiac arrest.
The sequence of events alone cannot establish a causal connection.
The emergency call to EKAB
The emergency unfolded rapidly.
At approximately 4:21 p.m., staff at the clinic contacted Greece’s National Emergency Aid Centre, EKAB, reporting that Mazonakis had suffered a serious cardiac event.
Seven minutes later, at approximately 4:28 p.m., an EKAB rescuer arrived at the clinic by motorcycle and began cardiopulmonary resuscitation (CPR).
An EKAB ambulance subsequently arrived and transported the singer to the nearest on-duty hospital, Elpis Hospital in Athens.
Mazonakis arrived at the hospital at approximately 4:45 p.m.
Doctors continued desperate resuscitation efforts
When Mazonakis arrived at Elpis Hospital, he was reportedly without spontaneous breathing and without a pulse.
Medical staff immediately continued CPR in accordance with the appropriate emergency protocol.
Doctors continued their efforts to revive him, but the resuscitation attempt was unsuccessful.
According to the hospital’s official statement, Giorgos Mazonakis was formally pronounced dead at 5:40 p.m.
The hospital said:
“On 9/9/2026 at 4:45 p.m., Giorgos Mazonakis, born in 1972, was transferred by EKAB ambulance without spontaneous breathing and without a pulse.”
The statement added that cardiopulmonary resuscitation was performed according to protocol, without a successful outcome.
The administration and staff of Elpis Hospital expressed their condolences to Mazonakis’ family and loved ones.
Witness describes the singer’s final moments outside the clinic
A witness who was in the Kolonaki area described seeing Mazonakis being taken from the clinic and placed into the ambulance.
The witness said the singer appeared extremely pale and had an oxygen device in his mouth.
The account offers a glimpse of the desperate scene surrounding the emergency, as paramedics worked to keep the singer alive before his transfer to hospital.
Questions surrounding what happened at the clinic
The circumstances leading up to Mazonakis’ cardiac arrest remain at the centre of the investigation.
Among the key questions are what happened after he entered the clinic, what treatment had been planned, whether the procedure had begun, what his condition was immediately beforehand and what exactly occurred before the emergency call to EKAB.
At this stage, however, it is important not to draw conclusions about the cause of the cardiac arrest without medical and forensic evidence.
The investigation is expected to examine the clinic’s medical records, the emergency response, EKAB’s documentation and any findings from the forensic examination.
Authorities will also seek to establish a precise timeline of the events leading to the singer’s death.
Police investigation begins
The circumstances surrounding Mazonakis’ death have prompted further scrutiny of what happened inside the Kolonaki clinic.
According to reports, police investigators attended the facility as part of the inquiry into the circumstances of the singer’s death.
The investigation is expected to establish the full sequence of events and determine whether any further questions need to be addressed regarding the medical emergency.
