I was in a car accident where I broke some bones and was hospitalized for 4 days. A day before discharge a cardiologist appeared at my bedside and said, "I'll bet you're wondering why a cardiologist is coming to talk to you." That's when I learned I had a 4.4 CM ascending aortic aneurysm. That was 8 years ago. Obviously it worried me at first because I didn't know anything about aneurysms. I took it very seriously in terms of continuing BP meds and not lifting anything over 30lbs. Got a few disapproving looks from strangers when I picked my wife and daughters up from the airport and didn't just go ahead and load their 50lb suitcases into the trunk. I have been walking 30 minutes everyday at a pretty brisk pace and lifting light weights 10-20lb dumbbells everyday for years now. My workouts are fairly intense but the important thing, I have found, is breathing correctly and not straining. I never hold my breath and strain and never max out the number of reps I could do. (I'm also loading in those suitcases now using a little creativity to accomplish it without straining). If someone is looking for help pushing a car out of the snow or helping load heavy furniture into a moving van, I'm not you're guy. I am now 70 years old and the aneurysm has not grown at all. I have a CAT scan with contrasting dye every six months for my own peace of mind. Just had one two weeks ago and still at 4.4. I don't know what the future holds in this regard but I really don't think about it too much. 4.2 CM is very small. I think as time goes on you will get used to it and it will become less and less of a concern. Just take care of yourself and listen to your cardiologist's recommendations. All the best. Brian
