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.
