Doc thanks for the reply, when you said "you may later on develop worsening heart failure", did you mean to imply it sounds like i already have some form of heart failure?
So, if i have the CTA and it's normal, I would still want to get a cath, if i've already done the CTA?
I would think not, and this is not one that you want to miss. The CTA is a good test especially in young people with non calcified vessels, but is is not 100% sensitive. A left heart cath will leave no doubts about the results, and the benefit is that they can perform an intervention at the time of the procedure. If you miss a lesion in your LAD, especially with your symptoms and poor exercise capacity, you may later on develop worsening heart failure or a heart attack. I would recommend proceeding with a left heart cath over the CTA for this reason.
Bottom line, i guess the main thing i'm wondering is..if CTA is normal then can I move on and forget about this? Would a normal CTA "over ride" this "abnormal" stress test?
