It’s great that you’re being proactive about understanding your condition. Your brother’s experience likely highlights something important—impact to the chest can increase the risk of complications, especially when there’s already an identified structural weakness in the aorta. The aorta is under significant pressure as it handles blood flow from the heart, and any trauma to the chest could exacerbate issues or cause a rupture. That’s likely why your brother was advised to avoid high-impact activities. In terms of lifting heavy objects, this is often discouraged because it can spike your blood pressure suddenly, which puts extra strain on the aortic wall. It’s in line with the idea of minimizing stress on the aorta, whether from physical exertion or impact.

What you might want to consider:

Talk to Your Doctor: It’s completely reasonable to ask your doctor specifically about impact risks. Physicians sometimes tailor advice to the individual based on aneurysm size, growth rate, and other health factors.

Monitor Your Blood Pressure: Keeping your blood pressure well-managed is critical. If you don’t already, consider using a home blood pressure monitor and ask your doctor what range is safest for you.

Lifestyle Adjustments: If impact avoidance wasn’t mentioned but you feel unsure, err on the side of caution. Low-impact exercises like walking, swimming, or cycling (on flat terrain) are generally better suited for individuals with aneurysms, but always get clearance from your doctor.

Family History Implications: Since your brother also had an ascending aortic aneurysm, there could be a genetic component. Have you and your doctor discussed whether this might warrant specific imaging or follow-ups for your condition?

Specialist Consultation: If you haven’t already, consider seeing a cardiologist or a cardiothoracic surgeon with expertise in aortic conditions. They can provide nuanced guidance on activity restrictions and overall management.

Ultimately, open communication with your doctor is key. I survived a 2015 complete Type A1 dissection. I was terrified for a couple of years with getting hit in the chest, mainly because my sternum was split for the surgery and it was really tender. You’re already doing the right thing by seeking more information and being mindful of potential risks. Take care. Peace.
