My girlfriend just had a heart attack?!

I cant beleive it. I was out at a restaurant with my gf. We were sitting at a table talking about how our days went and eating when all of a sudden she pauses a moment and winces. I ask what was wrong and if everything was okay and she said it must have been something she swallowed incorrectly. Then a minute later she pauses again and starts breaking heavy. She tells me that she does not mean to scare me but her chest and stomach hurt. I asked her if she needed to go to the bathroom or needed a glass of water. I flag a server down for some more water. She said she was alright but I felt something was wrong. Well then she placed her hand on her chest and she looked kinda scared. She said the pain was so bad and needed to go home. I helped her from her chair and then she fell over. The resaurant called an ambulance and she was taken to the hospital.

I called her family as soon as they called 911. We are both 17 and she is in very good shape. Very thin and healthy. Well from the updates they she had angina pectoris. I cant even spell it. Well by law I cant be with her in the hospital imediatly due to not being part of her imediate family. Very frustrating. Guys, is there any information I can go with to know exactly what it is we are dealing with. I just feel helpless now that I cant be there for her. What can I do. How can someone her age and her health have a heart attack. Just waiting is making me nervious.
