Hi again, CM60763f, and thanks for acknowledging my response to you. I am glad to hear you have an appointment next month with a cardiologist. As you pointed out, coughing can alter the pressures within the chest cavity. I am sure you will be speaking with the doctor about the potential effects this type of coughing my exert on the aneurysm(s).
Please do check back, if you don't mind, and let us know how this all turns out for you.
Good luck!
