What does it mean to have a very mild dialostic dysfuntion and what do you do about it. I have no high b.p. and am thin. There is no reason they can find for me having this. Had thought it was a M.V.P. for years. I am a 60 year old woman, who has been on beta block for 20 years for irregular heartbeat but heart other wise seemed normal. Do suffer from bad I.B.S. I have had breathing problems on walking up stairs and hills. I am very out of shape even though i am thin. I. b.S. has kelp me from getting out as much as i would like. I feel very scared about the stiff heart because all i see is heart failure on the interenet. Thank you for any help.
