I am in class III heart failure, and have been recommended to go for further catheterization, for diagnostic purposes. I had a massive heart attack, ten years ago and one stent installed. Currently, a recent MIBI stress test showed significant reduced contraction in my damaged heart muscle, compared to a few years ago. I am now thinking that going for the catheterization may be a waste of time, as the prognosis may be inevitable total failure. I am thinking of just living out the rest of my time with no further intervention, any comments.
