I have a leaky heart valve

[gja1000]

You may have a murmur that comes and goes. actually one that can be heard sometimes and not heard at other times. (i'm using my daughter's netbook computer and the shift key is too hard to use, so no caps). that kind of murmur is not at all serious.

they will likely do an ekg, and an echocardiogram. neither are invasive and don't take much time. you'll do fine.

i agree with yoou, your lack of energy is likely anmeia rather than anything heart related.

any blood pressure that is consistenly above 120 (on the top number) (and above 80 on the bottom number) is cause for concern and should be treated. the word consistantly is the key. you should get an automatic bp cuff and take it at home 2-3 times a day and see what it is over time. it has been suggested that high blood pressure, even a little high, can damage the white matter of our brain (among other things) and cause mental changes as we age. they wont treat a bp of 130/70 unlesss the top number stays above 120 all the time
