Man who survived heart attack captured the exact moment it took over his body

Heart attacks are arguably one of the scariest medical emergencies that can happen to a person, and one man accidentally caught his on camera.

He captioned the video: "It's the scariest thing that ever happened to me. Today while practising for a new video, those symptoms proved to be a heart attack.

"I was in pain and I panicked. I thought I was dying.

"Luckily my roommate came home early and immediately called 911.

In the shocking footage, which has been viewed over four million times, Alain can be seen looking uncomfortable as he washes himself in the bath, then he addresses his audience.

However, before he can even get more than a few words out, he stops and says 'what the f**k' before putting a hand on his chest.

At this point, it's pretty obvious that he's in some severe pain, which eventually worsens to the point where he doubles over in agony, clutching onto his chest.

As you can imagine, people were quick to weigh in on what they had just watched in the comments section.

One viewer said everyone could learn from Alain's experience, remarking: "This is a perfect example of why you should never be afraid to call 911 when you are experiencing feelings that don’t feel right.

"This poor guy could have been 60 seconds away from dying."

"He's so young and fit. Terrifying that this could happen at any moment to anyone," added a second, while a third wrote: "The worst part is... Is that if he were to have passed out from the pain, he probably would have drowned."

A fourth praised: "Thank you for posting this scary but informative experience.

"They always tell you the symptoms to watch out for but It really helps to see it actually happening and what it really looks like."

As reported by the NHS, some common heat attack symptoms include chest pain, shortness of breath, lightheadedness or dizziness and sweating.
