Evidence

Use of Physiology Significantly Reduces Major Adverse Coronary Events1-3

The CorMicA (Coronary Microvascular Angina) trial revealed that patients may benefit when Coronary Microvascular Dysfunction (CMD) is accurately diagnosed and appropriately treated.4 Learn more about diagnosing and treating CMD.

RFR clinical evidence derives from assessing over 3,500 lesions in 2,000 patients, and much of that evidence is from ILUMIEN I + PREDICT, VALIDATE RFR, IRIS-FFR and RE-VALIDATE RFR.5-9

Fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) is supported by more than 600 published studies including the FAME clinical trials.1,2,10

When integrated into cardiac cath lab procedures, measurement of FFR has been shown to reduce the incidence of major adverse coronary events (MACE) in patients being treated for complex coronary artery disease.1-3

The FAME study—evaluating complex lesions—examined FFR measured exclusively by the PressureWire™ Guidewire. Results showed that compared to angiography alone, FFR:

  • Allows more accurate identification of hemodynamically relevant stenoses2
  • Reduces mortality and myocardial infarction by 34%11
  • Lowers procedure and 1-year follow-up costs by 14%3
  • Does not increase procedure time2
  • Decreases the amount of contrast agent used2

Precise measurement of intravascular diagnostics relies on the PressureWire™ X Guidewire that combines excellent maneuverability—even in tortuous vessels—and reliable readings12, both of which can ensure accurate information in the cath lab.
