A member asked:

I have been diagnosis recently with small vessel disease of the heart along with big vessel disease . my cornary flow reserve numbers were 1.1 what is norma?

A doctor has provided 1 answer

Flow reserve: The 1.1 number indicates that the maximal flow in your coronary measurement was very little more than resting flow. As the number is max/resting each lab develops its own norms but about 3 would be normal in many labs.
