Beta Blocker Decisions

I wrote here about my last cardiology appointment and how my doc left it up to me as to whether or not I wanted to start beta blockers now or later, saying that he couldn’t really recommend I go one way or the other. Now, for those of you who don’t know, beta blockers are used in cases of Marfan Syndrome, in order to lower the heart rate, therefore decreasing the amount of stress put on the aorta, with the objective being to postpone heart surgery longer and to make the chances of aortic dissection lower. At the time, because my aorta is still fairly stable and because beta blockers can cause many highly unpleasant side effects (which with my medication history, I’d be very likely to pick up) I made the decision to stay off of the beta blockers for now. This was not carelessly decided mind you, I did a lot of research and spent many hours discussing and contemplating my choice. And of course, I’ve often wondered if that was a reckless or stupid decision.

This was back a few months when on average my resting pulse was always in the 60s and my blood pressure usually around 110/70.  And while my blood pressure hasn’t changed at all, my heart rate certainly has. Now it’s usually 100, often spiking to and staying at 120 – which is the recommended maximum limit for those with MFS who are not on beta blockers. This is very odd for me, nothing’s changed in my eating and exercising habits, caffeine intake etc. But it has me worried that I should definitely be on the beta blockers now. I was thinking of giving it a few more days and continually checking both my heart rate and blood pressure on the at home monitor we have, to see if anything happens before making an appointment with my GP. But this has been going on for a few weeks now and it doesn’t seem ready to quit.

I wish my cardiologist lived closer, right now he’s 8 hours away. My GP is good but she doesn’t know MFS the way he does. I don’t want to be stupid with my life, but I also seriously don’t want to deal with the monstrous list of effects that beta blockers can have on you, like, for instance, zapping all of your energy and making you feel tired all of the time. And headaches, I certainly don’t need help getting those, I do just fine all on my own.  I’m really struggling already and don’t know if I could keep any more fight in me if it got any worse. And for some silly reason, I feel like being put on beta blockers would be a huge negative turning point – like another notch in my “look what Marfan Syndrome is doing to me” belt.

What to do?
