TCT-626 Correlation Between Fractional Flow Reserve and Resting Full-Cycle Ratio (RFR) in the Assessment of the Clinical Significance of Borderline Stenosis in Patient With Stable Coronary Artery Disease

Journal of the American College of Cardiology, 2019
Resting full-cycle Ratio (RFR) is a novel nonhyperemic index to measure the severity of coronary artery stenosis, which was shown to correlate well with the instantaneous wave-free ratio (iFR). Our aim was to assess the correlation between RFR and fractional flow reserve (FFR) in the assessment ...

Influence of diabetes mellitus on the invasive assessment of myocardial ischemia in patients with coronary artery disease [PDF]

, 2023
Introduction: Current guidelines recommend physiological evaluation of borderline coronary artery stenoses using hyperemic (fractional flow reserve [FFR]) and nonhyperemic (instantaneous wave-free ratio [iFR] and resting full-cycle ratio [RFR]) methods ...

The impact of coronary microvascular dysfunction on the discordance between fractional flow reserve and resting full-cycle ratio in patients with chronic coronary syndrome

, 2022
BACKGROUND: Resting full-cycle ratio (RFR) is an alternative to fractional flow reserve (FFR) for the evaluation of borderline coronary artery lesions.

Relationship between coronary volume, myocardial mass, and post‐PCI fractional flow reserve

, 2023
Fractional flow reserve (FFR) measured after percutaneous coronary intervention (PCI) carries prognostic information. Yet, myocardial mass subtended by a stenosis influences FFR. We hypothesized that a smaller coronary lumen volume and a large myocardial

Biopsychosocial Determinants of Hand Function and Its Trajectories Over Five Years in Patients With Hand Osteoarthritis

Arthritis Care &Research, Volume 78, Issue 11, Page 1721-1731, November 2026.
Objective This study aimed to investigate hand function trajectories over five years in primary hand osteoarthritis (OA). Additionally, determinants of baseline and longitudinal hand function were assessed. Methods A total of 538 patients with both baseline and five‐year study visits were analyzed.
