How do you interpret results of a coronary flow reserve test?
Hi, I was diagnosed with small vessel disease along with the big vessels. They did a coronary flow reserve test with my heart cath. The results were 1.1 in the SVG-OM with the same results in a native graft RCA of 1.1 Can you explain the numbers? Thank you.

Hard to advise without knowing the precise anatomy of the disease of the "big vessels". I am also not aware of the use of coronary flow reserve in saphenous vein grafts (SVG's). The implication is that flow is normal in the SVG's; however, I'm not sure you can say that, as the efficacy of coronary flow reserve is established only for native vessels.
