What heart tests are  done before a decision for a heart cath .Ive had several . EKG, stressecho, Ct score, lexiscan, echo, 21 day monitor. All normal?

Risk: A heart cath is an invasive procedure with small but definite risks including stroke, heart attack, and death. The risk is well worth taking if non-invasive tests suggest serious disease, but it is never done because of curiosity or to satisfy a whim without good reason. ...Read more
