Post PCI Diastolic Pressure Ratio May Predict Risk Of Adverse Cardiac Events
An increasing body of evidence supports the use of either fractional flow reserve (FFR) or the non-hyperaemic instantaneous wave-free ratio (iFR) for intracoronary physiological assessment of intermediate coronary artery lesions. A recent study suggests that the incidence of target vessel failure (TVF) was higher in patients with post-PCI dPR ≤ 0.8. The study findings were published in the Netherlands Heart Journal on April 07, 2022.
To date, limited data are available on the distribution of NHPRs and their prognostic value. post-percutaneous coronary intervention non-hyperaemic pressure ratios (post-PCI NHPRs). Therefore, Dr J. Daemen and his team conducted a study to evaluate the distribution of a recently validated generic diastolic pressure ratio (dPR) after angiographically successful PCI in an all-comers study population and to study its association with 2-year clinical outcome.
