Can Coughing Increase Size and Risk of Aortic Anuerysm

Posted by mjm3 @mjm3, Jan 28, 2025

I am 67 years old with an ascending aortic aneurysm diagnosed last July at 4.1. I am scheduled for a six month CT angiogram next month to check for any growth – which I’m hoping there is none. However, over the last few weeks I’ve been battling a cold that turned into bronchitis that turned into mild pneumonia. Subsequently, I developed a cough that could be quite jarring at times. Late night googling found many different sources of contradictory information, but one stuck out that said “yes, coughing can be very dangerous for an ascending aortic aneurysm.” it did not specify how it was dangerous.
I have tried to contact my cardiologist twice about this and I must not be asking my question correctly because the nurse calls back with the reply that if I have questions about a cough, see my general practitioner. The GP said she’s not a cardiologist ask my cardiologist. It’s a vicious cycle. The urgent care doctor that prescribed antibiotics for the pneumonia had no idea about a cough correlating to a risk of aneurysm, but said to ask my cardiologist😵‍💫. Just wondering if anyone else had asked or spoken to their doctors about coughing, and if it causes the aneurysm to expand rapidly? I hope I don’t sound crazy, but I’m just really concerned about everything with this newly diagnosed issue. I want to be as safe as I can, but how do you prevent yourself from coughing when you’re sick. Cough medicine only goes so far. Thanks for any insight.

It is maddening. And to make matters worse, I saw another cardiologist in the fall for a second opinion. Now when I went to ask my original cardiologist the cough related question-again today, I was met with a very snarky nurse that said "according to MyChart you already spoke with another doctors office so who are you working with?" Yikes.I guess there is no privacy, either. (Note I have been with my original cardiologist since 2008 when I developed mitral valve regurge. I sure was not expecting such a send off. )

Thats awful. I recently have had elder disrespect. You can feel it in your bones when someone just disregards you.
Better not to even make eye contact. Even though thinking about it....it's there problem not ours ( if you are not older it still applies) 🙂

Cough is symptom that helps Dx TAA. I have mild Asthma and I do cough especially when I have an excerbation, like now. Cough drops and nite quil only go so far. If can send an email to your cardiologist do so.

Thank you so much for sharing. My spouse has been diagnosed with an over 4 .5 aneurysm and family GP is quite blaise about it and not doing enough follow-up in my humble opinion. Sends off for the odd CT but does not seem to know much or care for that matter. Your info is very good helpful esp. the surgeon recommendation. Stay well and thanks again!

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!

@mjm3 you know what really helped me because I have blood pressure spikes too, primarily from the anxiety regarding whether the thing was growing, (so I have been my own worst enemy at times). Someone on here told me to breathe in through my nose 4 seconds hold my breath 4 seconds and breathe out through my mouth 4 seconds and start all over again. this activates your parasympathetic nervous system and lowers both your blood pressure and your heart rate (if the spike is indeed a result of anxiety). The spiking blood pressure is much more dangerous than the coughing, but even that probably won’t increase its size. Your aorta is designed to take a lot of pressure and be quite flexible. I felt better after I got my second and then my third CT scan and it hadn’t changed so now it’s been three years at 4.2 or 4.1 depending on who measures it. I did have a blood pressure spike myself and my 3.5 root measured 3.7 on an echo …
I’m hoping that’s just an anomaly of the measuring but I get another CT scan in April.
