When you think of someone suffering a heart attack, that thought is usually synonymous with old age, poor health and obesity.
However, that's not always the case.
It certainly wasn't for 38-year-old Dancing With The Stars turned Studio 10 star Tristan MacManus who has revealed he suffered not one but two terrifying attacks.
"I woke up and I was on the ground," Tristan told Sydney Confidential of his first heart attack which he experienced at just 26-years-old while dancing in Las Vegas.
"To be honest, they didn't really tell me there was anything wrong with my heart so I didn't really think anything of it."
The TV host's grandfather had died of heart attack at age 36, the same age at which he then suffered his second attack.
"I just started beating my chest, I could feel my heart in my head. I felt tingles down my arms."
It was then, two years ago now, that Tristan was told he'd had a second heart attack and was diagnosed with myopericarditis, which is inflammation of the heart muscle and the pericardium.
"Your arteries are supposed to sit on top of your heart, it turns out mine go through my heart."
Despite living with the fear he could suffer another attack at anytime, only managing the disease by staying on top of his health, his main concern is his children.
Tristan and wife Tahyna Tozzi of Blue Water High fame, share four-year-old daughter Echo and one-year-old son Oisin and have a third child due in April.
"There will always be that fear. I couldn't think of anything else that would be more scary than not seeing my kids grow up."
"Three strikes and you're out."
