Aortic Aneurysm - Losartan study on mice shown to reverse size of aneurysms???

[Shidaddy]

Hi. I have two questions:



1) Do I need surgery soon?



I have recently been diagnosed with an aneurysm of my aortic root of 4.8cm and also my ascending aorta of 4.9cm. My aortic valve is trileaflet and still in good shape. My ascending aorta is 1.9 x the diameter of my descending aorta.



- I'm a 41 year old male

- 6'2" and 210 Lbs.

- I'm athletic (or I was before my diagnois)

- I do NOT have marfans syndrome, but apparently a connective tissue disorder.

- I have a history of "massive heart attacks" on my mothers side (no autopsies were done)

- I feel fine. If it wasn't for the CT scan findings I would not realize there is an issue.





2) Cozaar/Losartan: Is there a chance that I can avoid surgery by taking Cozaar. If so, how much should I take each day?



I just read about a study on mice with marfan syndrome. Apparently, their aneurismal aorta’s, and aortic roots returned to normal sizes after being given Losartan over several months. I understand they are now testing this with humans (adolescents), and I imagine that a lot of people are getting their hopes up and putting off surgery… as I would like to do. Can I test this on myself for 6 months to a year, and see if I have a similar result... and delay surgery.



The surgery to repair my aneurysms scares me. If there is a chance that I could correct the problem without having surgery, I would like to give it a try. Thank you for reading this.

Hi shidaddy,



You and I are in somewhat similar situations. I'm 6'1", 190 lbs, used to be athletic before my diagnosis, not quite Marfan but some type of milder connective tissue problem, 3.8 cm aortic root, tricuspid aortic valve (we are fortunate that we do not have bicuspids!). Kind of throws a cramp in your style, doesn't it?



I came back from my cardiologist appt 6 months back with some more aortic growth, as usual. I was disappointed and said a prayer to the Lord Jesus Christ - and a day or two later, I got an email from the National Marfan Foundation regarding the losartan studies. Wow, what a direct answer.



I called my doc up and he prescribed me not Losartan but valsartan, which is a similar drug. He put me on a very light dose (80 mg/day), about half of what someone my body size would be taking in Dr. Dietz' study on adolescents this fall.



Fast forward 6 months - I had my follow-up echo last Monday. Thank the Lord - no growth. All my numbers were "identical to last time," according to my cardio. That is unusual because my aorta had been growing up until then. We cranked up the dosage to 160mg/day, which is more in line with what someone my size should be taking. I'm praying that at my next echo, the aorta will have shrunk. Who knows? I'm just happy for now.



I've spoken with other people taking losartan, and they also have stabilized their aortic roots. One lady I know was taking a pretty high dosage (300 mg of Avapro/irbesartan per day, the max you should take for that drug) and her aorta shrunk from 4.2 cm to 3.7 cm over a 6-mo. period.



None of that answers your question directly, but there is indirect, un-official basis for having a lot of hope for these studies. Talk to your cardiologist and see if he or she will prescribe some for you at a *HIGH* dosage. You're almost at the threshold for surgery, so tread carefully. I'll pray you experience the same kind of (seeming) success as me, if not better!

PS - the surgery IS scary, but if done by an experienced surgeon, the success rate is extraordinarily high, and the life expectancy is basically normal. Many of the post-operative deaths you hear about are folks that are already dissecting/rupturing, the elderly, or those already in some sort of bad heart shape. If you're generally healthy and you go to a good surgeon, there is nothing to fear!

Hope the drug works for you. I had a 5.0 cm aneurysm of the ascending aorta, very similar to yours, normal valve, only the ascending aorta, etc. I'm male, 48, 160 lbs, athletic, non-Marfan's. I had surgery in early '04. I was back on my bicycle in 6 weeks, it took about 6 months for me to feel really recovered, and a year before my sleep was back to normal. Today, I ride about 160 miles per week at a fairly high intensity level (I used to race competitively). The only thing I don't do is lift very heavy weights. Otherwise, no problems. I take a low dose (75 mg daily) of metoprolol, a beta blocker. It cuts my aerobic capacity by about 10%, you get used to it.



If you do get to where you need surgery, make certain you go with a highly experienced surgeon who has done hundreds of aortic repairs. Cleveland Clinc has a great reputation. I had my surgery done by Dr. Vincent Gaudiani in California, he's done hundreds of such operations. I had a mini-sternotomy (only 4" near-invisible scar), and was on pump for only 25 minutes. Don't get someone who has only done a few of these!

i'm in the exact same situation as shiddady and nick.  I'm 44,, 6', 220 lbs, my aortic root is ~4.3cm and I'm on 80 mg of valsartan.  The interesting part was that a year ago my aortic root was measured at 4.8 by echo and I was talking to surgeons.

We did an MRI and it measured 4.2. The echo has about a .2 margin for error.  An echo last week measured the aortic root at about 4.3 or 4.4.  My point is to get an MRI to baseline it first and then once every year or two just to check it.

I watched it grow .2 about every two years since it '92, it was 3.9 then.  Don't worry about about a .1 or .2 change it's not that accurate.

I'm also hoping to see it shrink but who knows. I figure I have 7 to 10 years to see but who knows about that too.  

not sure if you'll read this since you posted a year ago.
