Instantaneous wave-free ratio (iFR)

Dr Ricardo Petraco is a British Heart Foundation Fellow working with the coronary physiology group of ICCH, led by Dr. Justin Davies. He has been involved in the early development of the Instantaneous wave-Free Ratio (iFR), a new vasodilator-free pressure-only index of coronary disease severity.

His research interests include understanding how the distribution of disease severity in study populations affects the performance of diagnostic indices in coronary disease. This has led to the development of the V-test, a new statistical approach to calculate diagnostic accuracy, which is independent of the sample distribution.

Recently, his focus has been on further understanding the relationship between coronary pressure and flow, particularly on how increased coronary flow during hyperaemic stimulus can affect the performances of pressure-only indices such as iFR and fractional flow reserve (FFR). He developed automated software which enables researchers to evaluate coronary haemodynamic indices in a single study platform.
