Thank you so much for such a thorough and thoughtful answer to my question. Since 4.1 was my baseline – first aortic aneurysm measurement I have nothing else to go by. I have no idea how long I’ve had it. It was discovered as an incidental, finding during a CT angiogram to rule out any blockages after an unusual Blood pressure spike that was severe enough to put me in the hospital overnight, where they could not find anything that could’ve caused a spike. This post pneumonia cough has been driving me crazy for the last week, but it has not been chronic. It has been jarring at times. My cardiologist did get back to me yesterday and said there is “relatively low risk for even a harsh cough over several weeks to cause an aneurysm concern” but who knows. I guess I will find out when they do the new measurement at the end of February till then I know I’ll be freaking out about it. I have researched a surgeon at your recommendation and found someone that seems really good. That’s also in my insurance, which is important. I’m going to ask my cardiologist for a referral since they won’t see anyone without a referral. Thank you again!
