A PREVIOUSLY undiagnosed congenital heart condition is responsible for the sudden death of popular Sydney bodybuilder Aziz Sergeyevich Shavershian.

The parents of Russian-born Shavershian, known as Zyzz to his fans, today said they had received a copy of their son's official post-mortem from the Department of Foreign Affairs and Trade which confirmed his tragic cause of death.



They said the 22-year-old had shown some minor symptoms in recent months, including occasional shortness of breath and high blood pressure, and that there was a family history of heart problems.



"He touched the hearts of so many people because he was such a good person," his father Sergei Shavershian said.

Russian-born Shavershian died after being found unconscious in a sauna, a post on his fanpage said yesterday.

The 22-year-old did not compete in bodybuilding competitions but built a strong reputation with tens of thousands of Facebook fans who admired his muscle-flexing and adopted his vision of "getting aesthetic".

Those fans have swamped social network sites in the last 24 hours denying that he has died.

However, DFAT reconfirmed the death and said the NSW man died in Thailand and that his family requested privacy.

Mr Shavershian, who began bodybuilding after completing his HSC to build strength and attract girls, lived in Eastwood in Sydney's northern suburbs and was a personal trainer, aspiring model and part-time stripper.

He also sold a whey protein supplement named Protein of the Gods.

On Simplyshredded.com, he recently spoke about "feeling like a little bitch when I was out with girls" while talking about his childhood.

Posts on a Facebook memorial page said Mr Shavershian suffered a cardiac arrest three days ago. His 25-year-old brother Said, who is also a bodybuilder and known as Chestbrah, said he was devastated by the death.

"Would do anything to have you back home safe with me. 22 years old. U were far too young," he wrote on Facebook.

"I F ... miss you sooo much my baby brother, I can't live without you comeback please. Don't do this to me."

Chestbrah was last week fined $400 in Parramatta Local Court for possessing anabolic steroids.

Fanpage zzyzcentral.com said the cause and circumstances of Mr Shavershian's death were unknown: "It is a sad day for all of those whose lives Zyzz inspired and motivated. The best way we can cherish his memory is by living life to the fullest, by training hard, getting aesthetic and not taking life too serious."
