21 year olds don't have heart attacks without it being trauma related, chemically induced, or some congenital issue. It being a coronary artery issue is possible, but very unlikely, even congenitally speaking...thus, I am wondering if it was a valve issue, or even perhaps a dissection in the aorta, maybe around her heart. I have not heard for certain, nor will anyone else until probably tomorrow at the earliest.

Very sad. In seven years working in cardiology myself, I stented one 17 year old because of trauma on a football field. Everyone else that I can recall was over 30. Of course we saw plenty of young people whom had valve and muscle damage issues (the latter usually from a viral infection). Most children or teens that we worked on were diagnosed at a very early age and had undergone multiple surgeries, treatments, etc., so it wasn't anything to consider unexpected. Hearing about TD, now this, and also being aware of another young girl currently in the hospital in Monroe is very, very unusual being all within a couple of months.

Praise God for your time with your loved ones. Don't waste even a second.
