Hello I am a 56 yr old white female. The early part of Nov I had some type of episode where I passed out and loss consciousness while donating blood. I ended up in ICU and they thought I had a stroke, but everything came out ok on that part. I also had an echo cardiogram which I faild terribly and a stress in which I did horrible. I also had a cath,which showed no blockages, but he said somthing about my aorta which I didn't catch. I am going today for a CT scan to check to see if I a have an aneurysm on my aorta. I have a family history of heart problems my father died of from when they put a defective valve in his aorta, my brother passed away from a heart attack, My grandmother died from a aneurysm on her aorta which was throwing blood clots and my mom's youngest sister has an aneurysm on her aorta. My grandfather also died after many strokes. Should I be worried?
