Stop smoking Now!, See a very good cardiologist. I was told that at 5 I would need open heart surgery. I’m 78 and by the time it’s 5 I could be 88 and then not a candidate for surgery. You have a choice. I never smoked or drank. I inherited this from mother. Both my brothers have already had open heart surgery. They didn’t have a healthy lifestyle .

I had a thoracic aortic aneurysm repair surgery (open heart) 4 1/2 years ago, it went uneventfully, before surgery my surgeon gave me a >99% probability of having no complications due to my general physical fitness, among the things that he listed was the fact that I had never smoked.

Never too late to improve your physical health, exercise (cardio and strength but do not lift heavy weights), stop smoking and eat well. Find a cardiologist who is an expert in aneurysms, not all of them are, there are some that specialize in aortic aneurysms, ask a lot of questions, get comfortable with your Dr (he/she should have a plan to monitor your progress) and follow his/her advice, and at the top is controlling your BP.

Exercise and a healthy lifetyle will not only improve your fitness for surgery if/when needed, but will help control your BP and axiety about the aneurysm.

All the best to you!!!!

Stop smoking. Do it now. I've given up wine and salt, and it's a pain in the you-know-what, but I want to be as healthy as I can. You can do this.
