I know this might sound odd considering what I've just gone through, but there is nothing wrong with my heart. True, I suffered from Aortic Stenosis, but that only involved my Aortic heart valve, but my heart is fine, no blockages, no angina, no arrhythmia, etc. And while it is true that I have high blood pressure, it's a congenital condition that I've been treated for since I was a young man and in fact, my heart valve could also have been congenital. Historically I have low cholesterol and have never smoked. I also consume no caffeine (having never had a cup of coffee in my life and have had no sodas in over five years). Also note that my heart valve is a tissue valve and so there is no need for me to take blood thinners, except for a single baby-aspirin each night, which I've done for over 10 years now.
I feel better now than I have in years. At least a dozen people have even remarked that my appearance is better, more healthy looking, something that I had never even thought about, but apparently people have noticed a difference.
Anyway, thank you for your concern...
