Oh, yes, instead just go to your local Chiro quack for your cardiovascular problems! Sheesh....
I am sure serious cardio problems can't be in what I am about to describe, but I can tell you that after suffering anxiety attacks that turned out to be directly related to my mitral valve prolapse.
I started to go to a chiro. I don't know why, to relieve tension mainly because of the anxiety attacks). Even though my mitral valve bothered me steadily for 8 years, I never had a problem with it or anxiety attacks after I started to see the chiro.
