(Single Best Answer) Question 553: Regarding Coronary Flow Reserve 1. Absolute flow reserve is the ratio of coronary flow during maximal vasodilation to the resting value 2. Relative flow reserve compares maximal vasodilated flow in a stenotic region with an assumed normal region in the same heart 3. Fractional flow reserve assesses maximal flow indirectly from coronary pressure measurements distal to a stenosis during vasodilation 4. Fractional flow reserve can identify the contribution of abnormalities in microcirculatory resistance to the development of myocardial ischemia
