When I got back up to the hospital this morning, the cardiologist was in mom's room. He said that her ECG had shown that her heart was 50% damaged. They decided to forego the stress test and do an angiogram instead. The doctor wants to see if there are anymore potential blockages or narrowing of her arteries so he'll know what her chances of having more heart attacks are, as well as see if she'll need an angioplasty or a stent to widen any narrowings.
They are doing the angiogram as I type this blog post, so I should know more in a couple of hours. I'll be sure to update as soon as I can.
Thank you to everyone for your support. I have the best friends in the world!
