My brother, Chris, had a heart attack when he was 31 and died. It was sudden and although he felt no pain, everyone around him still feels the shock and pain of his loss every day. 

On top of my shock and grief I felt emotions like guilt and confusion. He was relatively healthy, he was young, his wife was about to have another child. Why did this happen? I went to my doctor and out of an abundance of caution, my cardiologist put me though the ringer. I've never had more heart tests or proceedures in my life. To my suprise, they found something.

Although I did not have the same irregularity my brother did. They still wanted to opperate. I had my first heart proceedure a year after my brother died, and it was unsuccessful. My condition wasn't a death sentence, many people live with it, but over time it can weaken the heart muscle, and without my brother I never would have known about it. A month later I had another heart proceedure, this time successful, although I did have a small hemmorage towards the end that freaked my dad out (sorry, dad). 

The point is, I owe my brother everything, and I always have. My big brother is always looking out for me and I'll never be able to thank him enough.
