About work

@sedo I suffered an aortic dissection at age 50, and I can tell you firsthand that this is something you need to take very seriously. The good news is that you know about your aortic enlargement now, before a catastrophe occurs. That gives you an opportunity to manage it and hopefully prevent a dissection. An aortic dissection is a life-threatening emergency. If your aorta dissects while you're at sea, far from a hospital capable of performing emergency aortic surgery, your chances of surviving could be extremely poor. That's the reality you need to understand.

I'm a lawyer, not a physician or a seaman, so I can't tell you exactly what limitations your job will require. But I can assure you that you'll likely need to slow down and make some significant adjustments. Controlling your blood pressure is critically important. So is avoiding heavy straining, breath-holding during exertion (the Valsalva maneuver), and activities that cause sudden spikes in blood pressure and heart rate. Unfortunately, pulling, pushing, and lifting heavy objects can involve all three. At 4.4 cm, your aorta is enlarged, but that doesn't necessarily mean you need surgery or that you must quit your job. Much depends on which part of your aorta is enlarged and your individual risk factors. You really need to sit down with an aortic specialist, explain exactly what your work involves, and get specific guidance about what you can safely do.

My advice is to take care of yourself, reduce your stress, control your blood pressure, and don't push your physical limits. An enlarged aorta can be life-threatening even though you can't see it, feel it, or tell that anything is wrong. You have something I didn't have at 50: the gift of advance warning. Use that knowledge to protect yourself. Your livelihood matters, but your life matters more. Your family matters even more. Peace.

The only person who can give you a meaningful answer to this is your cardiologist. We don’t have any information about potential risk factors, such as whether or not you have bicuspid valves, hypertension, the condition of the arterial wall, or the location and shape of the aneurysm.

A reading of 4.4 doesn’t necessarily have to be alarming, but this, too, depends not only on whether you have risk factors but also on your body surface area (BSA) and height.

I understand very well that this is weighing on your mind; I, too, have a physically demanding job and have decided to delegate the really heavy tasks to others. I’m fortunate to be able to do that, but I can imagine that if you work on a boat, you don’t have that option.

When I read the stories of aortic dissection survivors, it’s clear that this is something you must do everything you can to prevent.

I wish you much wisdom and strength in this difficult situation.

That is a tough call since you are very young to have this situation but at the same time your job is extremely physical and at least the doctors caught it before a situation happens away from the dock. You are performing a “young person” job which if you have family what effects or risks for their sake?

Not just any cardiologist will do, though. I find that out the hard way. If I hadn't gone to a cardiologist that specializes in these things, I would have been gone 2 years ago. I got a second opinion from a congenital specialist and the team found 4 additional serious things that the local cardiologist completely missed. He also blew off the ascending aortic aneurysm and aortic root aneurysm.

You’re 100% right about this.

I was first diagnosed with a 47-mm mid-ascending aortic aneurysm in March 2026; this happened during a so-called private preventive health check using a whole-body non-gated angiografie MRA.

Naturally, they referred me to my hospital for further evaluation.

And here’s the “best” part: during the ultrasound, they completely overlooked the dilation. I understand that a dilation in the mid- to distal ascending aorta is very difficult to detect, but I do hold it against the cardiologist that he didn’t even consider the possibility that this dilation might have been missed. Because the root and the proximal segment are very easy to see on an ultrasound, but the rest is tricky. And a highly experienced cardiologist should always take that into account, especially with these kinds of potentially life-threatening conditions.

He casually stated that in my case, the ascending aorta measured 40 mm—which, given my BSA, was in the high-normal range—and so I received no lifestyle advice whatsoever; he told me I should definitely continue with powerlifting and that there were no weight restrictions.

And in July, a gated CT scan revealed that it was already 49.3 mm—it wouldn’t have been very healthy if I’d continued for years with the training regimen I’d been following for so long...

So you can understand why I immediately switched to a highly respected aortic center .
