Lucy, it is good to find about such things, of course, as knowing can enable them to help prevent any manner of of dire things, including strokes and heart attacks. Knowing can equal prevention.:-)

The only heart cath I've ever ahd was in 1979, so they have probably improved a lot. The only thing that bothered me was having to stay flat on my back for such a length of time, during and after; that was very painful. The angiogram itself was NOT and I even got to watch the catheter as it was moved throughout my heart and saw the chmabers, valves, etc., which was really interesting!

You can find more information at PlainSense.

If you have any interest in alternative methods of healing clogged arteries, etc. please send me a PM, as I've explored quite a bit and would be happy to share.

All the best,

kat
