Key result
Myocardial fractional flow reserve (FFR) provides a reliable assessment of the functional severity of coronary-artery stenoses compared to noninvasive tests.
Why the study?
Does myocardial fractional flow reserve (FFR) accurately assess the functional severity of moderate coronary-artery stenoses compared to noninvasive tests?
Does myocardial fractional flow reserve (FFR) accurately assess the functional severity of moderate coronary-artery stenoses compared to noninvasive tests?
Myocardial fractional flow reserve (FFR) is introduced as a new invasive index to assess the functional severity of moderate coronary stenoses compared to standard noninvasive ischemia testing.
Supports FFR for functional stenosis assessment; leaves open outcome benefit versus noninvasive testing alone.
The clinical significance of coronary-artery stenoses of moderate severity can be difficult to determine. Myocardial fractional flow reserve (FFR) is a new index of the functional severity of coronary stenoses that is calculated from pressure measurements made during coronary arteriography. We compared this index with the results of noninvasive tests commonly used to detect myocardial ischemia, to determine the usefulness of the index.
