keygen nero 9 lite il testamento di sherlock holmes crack pc FFR has recently become recognized as the gold standard of physiological assessment of intermediate coronary stenosis, wrote lead author Jelmer Westra and colleagues. Armed with this knowledge, clinicians can make better decisions about whether to perform percutaneous coronary intervention (PCI) or not.

In this analysis of 317 vessels from 272 patients with stable angina, QFR demonstrated better agreement with FFR than two-dimensional angiography for identifying significant vessel obstruction. Significant obstructions were defined as below 0.80 for FFR and QFR and above 50 percent diameter stenosis upon angiography.

The corresponding values for angiography were 44.2 percent and 76.5 percent. Also, the area under the receiver curve was 0.92 for QFR versus 0.64 for angiography.

However, they said randomized trials are needed to evaluate whether QFR calculation leads to noninferior clinical outcomes versus FFR in patients with intermediate stenosis.
