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 ...

Advances in Nano‐Immunomodulatory Systems for the Treatment of Acute Kidney Injury

Advanced Science, EarlyView.
Based on the biodegradability and the immunological reactiveness, IMNs can be broadly classified into four categories. The first category includes types of biologically derived materials that cause immunomodulatory action and biodegradability like nanoparticles of cell membranes, extracellular vesicles, and exosomes.

CT-FFR: Clinical Application

Majalah Kardiologi Indonesia, 2018
Invasive fractional flow reserve (FFR) is the gold standard for guiding decision making to identify patients who would benefit from revascularization. Now, computed tomography can also do that by using computational fluid dynamics to calculate fractional

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 ...

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.

Injectable pH Responsive Conductive Hydrogel for Intelligent Delivery of Metformin and Exosomes to Enhance Cardiac Repair after Myocardial Ischemia‐Reperfusion Injury

Advanced Science, EarlyView.
Injectable pH responsive conductive hydrogel for intelligent delivery of metformin and exosomes to alleviate myocardial ischemia‐reperfusion injury. The hydrogel responds to the weakly acidic microenvironment of ischemic injury and can significantly reduce the production of intracellular ROS and enhance cardiac conduction, thereby resisting apoptosis ...

Invasive physiological indices to determine the functional significance of coronary stenosis

International Journal of Cardiology: Heart & Vasculature, 2018
Physiological measurements are now commonly used to assess coronary lesions in the cardiac catheterisation laboratory, and this practice is evidence-based and supported by clinical guidelines. Fractional flow reserve is currently the gold standard method
