Can Coughing Increase Size and Risk of Aortic Anuerysm
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.

I've had a few CT scans done. 1/20/25 and 9/17/25.
The good news out of it is at least there's NO change.
Ascending thoracic aortic aneurysm is still the same measurement 4.3 cm.
Another CT scan is scheduled one year out in September 2026.
Over the Summer of 2025
I hiked up Mt. Whitney 14,508 ft. elevation, six (6) times.
I Googled risks of high altitude hiking with an aortic aneurysm and it doesn't read well.
Cardiologist I'm seeing had a different opinion than my online research. Said good to go with the hiking to over 14 thousand foot elevation.
I felt fine on the hikes and being the CT scan after is the same as before the half a dozen times up Mt. Whitney looking like very thankfully my Cardiologist was correct.

1 ReactionIm 67 w/ a 4.2 AAA. Been watching it yearly with an echocardiagram and cat scan 2x since discovery at age 60.
About cough. It is my understanding that severe coughing can be problematic. My pcp prescribed benzonatate 100mg for an extreme cough following pneumonia last year. And I used it again recently at the tail end a cold.
@pamela78 hi I just read your response to the individual with cough concerns and I appreciate your response to that person as more than a “humble opinion” but more spot on as I’ve experienced the same seemingly indifference from my cardiologist who seems to be in a hurry to go turn another door knob as if my concern over a 4mm ascending aortic aneurysm was insignificant. At 70 y/o it frightens the shit out of me, so thanks for basically reassuring me that I wasn’t being overreacting to my cardiac concerns. Thank you! Robert

2 Reactions@moonboy this is some of the most constructive advice I have gotten. Thank you. I live in st.Paul and hoping you could give me the name and contact info for the cardiac surgeon you mentioned? I’m with Health Partners and I haven’t had consistent high quality advice from the doctors I have seem. I’m 85 yrs old and have quite a large thoracic aneurysm. I’ve been told that surgery would be risky at my age, and I believe that.
My surgery was done emergently in La Jolla California in 2015 when I was 50 years old. I am now almost 61. My thoracic surgeon has since retired (Dr. Anthony Perricone). At 50, this emergency surgery was brutal to for me to survive. At 85, I think I would certainly get a second opinion from a Mayo doc or University of Minnesota Heart Care Center-Fairview doc. My understanding as a layperson is that aortic repair at age 85 carries substantially higher risk than at age 50 because the body’s resilience, organ reserve, and ability to recover from major surgery diminish with age. Older patients often have additional medical problems—such as coronary artery disease, kidney impairment, or lung disease—that increase the likelihood of complications like stroke, heart attack, renal failure, or prolonged recovery. Their connective tissues are also less elastic, which can complicate the surgical repair itself. At age 50, by contrast, the heart, kidneys, and lungs generally tolerate anesthesia and circulatory arrest far better. Healing is faster, and the long-term survival benefit of repair is much greater. All that said, I'd get a second opinion. Ask for a referral and let the second advise you. Peace.

Im 75 very soon and Ive always had such a Big cough..Ive often wondered about this bc if lifting isn't good my big coughing must be bad..Great question...

ChatGPT: That’s an excellent and very important question.
In general:
A short period of coughing from a cold is unlikely to cause a significant or permanent increase in the size of an ascending aortic aneurysm.
Here’s why and what to keep in mind:
⸻
🫁 What happens during coughing
• When you cough forcefully, your chest (thoracic) pressure temporarily rises.
• This briefly increases pressure inside the aorta (the main artery leaving the heart).
• These spikes are transient — they last only seconds — and in most people (even those with a mild aneurysm), they do not cause measurable dilation.
⸻
🫀 In the case of an aortic aneurysm
• The aorta in someone with an aneurysm is already weaker than normal, so persistent or severe strain can theoretically add stress.
• However, routine coughing from a cold or flu usually does not make an aneurysm enlarge.
• What can contribute to faster growth over time is chronically elevated blood pressure, smoking, or connective tissue disease (like Marfan or Ehlers-Danlos).
⸻
⚠️ When to be cautious
• If coughing is very forceful, prolonged (weeks), and causes chest or back pain, or if you experience sudden pain, shortness of breath, dizziness, or a tearing sensation, that’s an emergency — those could signal an aortic complication.
• For someone with a known ascending aortic aneurysm, keeping blood pressure well controlled during illness (and avoiding unnecessary strain) is key.
⸻
✅ Practical steps
• Treat the cough early (humidifier, cough suppressants, hydration).
• Monitor your blood pressure.
• Keep up with regular imaging (CT or echo) as your doctor recommends to track the aneurysm’s size.

3 Reactions@moonboy ..TY for this information..I was seeing a vascular Dr & bc I do have COPD, I have regular CTs done w/o contrast..I was 1 cm now after 4yrs its a , 3 so is with contrast, that important to read the correct sizes ?
@absma What about a stent? Is that possible for you?
