Pressure-derived measurement of coronary flow reserve

Journal of the American College of Cardiology, 2005
We aimed to validate the technique of measuring the coronary flow reserve (CFR) with coronary pressure measurements against an established thermodilution technique.The CFR has traditionally required measurement of coronary blood flow velocity with the Doppler wire and, more recently, using a thermodilution technique with the coronary pressure wire ...

Coagulation Matters: ATIII‐Enriched Biomolecular Corona Enhances the Hemocompatibility of PEG Nanoparticles

Advanced Healthcare Materials, EarlyView.
Engineering of a functional protein corona with a synergistic heparin‐ATIII complex significantly improves hemocompatibility of PEG nanoparticles. Through deliberate engineering of the protein corona, a 4‐fold reduction in coagulation activation (F1 + 2) without inducing adverse thromboinflammatory reactions (CD11b, C5a) is achieved without disrupting ...

Fractional Flow Reserve or Coronary Flow Reserve for the Assessment of Myocardial Perfusion

Current Cardiology Reports, 2018
Purpose of ReviewAccumulating evidence exists for the value of coronary physiology for clinical decision-making in ischemic heart disease (IHD). The most frequently used pressure-derived index to assess stenosis severity, the fractional flow reserve (FFR)

Is Discordance of Coronary Flow Reserve and Fractional Flow Reserve Due to Methodology or Clinically Relevant Coronary Pathophysiology?

JACC: Cardiovascular Imaging, 2012
The purpose of this study was to determine whether observed discordance between coronary flow reserve (CFR) and fractional flow reserve (FFR) is due to methodology or reflects basic coronary pathophysiology.Despite the clinical importance of coronary physiological assessment, relationships between its 2 most common tools, CFR and FFR, remain poorly ...

Mechanisms of Myocardial Ischemia in Hypertrophic Cardiomyopathy : Insights From Wave Intensity Analysis and Magnetic Resonance [PDF]

, 2016
Background: Angina is common in hypertrophic cardiomyopathy (HCM) and is associated with abnormal myocardial perfusion. Wave intensity analysis improves the understanding of the mechanics of myocardial ischemia.

Human Skin Models in Biophotonics: Materials, Methods, and Applications

Advanced Healthcare Materials, EarlyView.
This review discusses how the optical properties of human skin can be replicated in human skin models. It describes the principles, materials, and techniques used to develop artificial skin for biophotonics research. Finally, the article highlights recent advances and shows how these models improve the study of light‐skin interactions without the need ...

Dilated cardiomyopathy and coronary flow reserve [PDF]

European Heart Journal, 2006
We read with interest the article by Rigo et al .1 about the prognostic impact of coronary flow reserve (CFR) by Doppler echocardiography in dilated cardiomyopathy. The authors conclude that in patients with idiopathic dilated cardiomyopathy, the prognostic role of impaired microvascular CFR has been shown to be unfavourable.
