I started tasking a daily coated aspirin on January 15th as suggested by my surgeon. I've never taken a daily aspirin before, only one a week, but I never had any reaction to aspirin like stomach discomfort. The coated aspirin is supposed to be easier on the stomach so I don't anticipate any problems.
I'm not exactly sure what taking a daily aspirin is supposed to do for me. The literature that came with the aspirin bottle shows a little graphic of blood flowing through an artery with platelets shown as less likely to clog a narrowing. So I suppose with a narrowed aortic valve, the aspirin would make clot formation there less likely. Or, perhaps the surgeon felt that I should be taking it just in case I have coronary artery disease. In any event, with a history of stroke on my mother's side of the family, it's probably a good idea for me to take aspirin.
