Age and Vasodilator Response to Different Hyperemic Agents: Adenosine versus Contrast Medium

Reviews in Cardiovascular Medicine
Background: Age-related remodelling has the potential to affect the microvascular response to hyperemic stimuli. However, its precise effects on the vasodilatory response to adenosine and contrast medium, as well as its influence on fractional flow ...

Insights from electromechanical simulations to assess omecamtiv mecarbil efficacy in heart failure

The Journal of Physiology, Volume 604, Issue 13, Page 5493-5511, 1 July 2026.
Abstract figure legend Impact of Omecamtiv Mecarbil (OM) on in‐silico models of heart failure. A mathematical electromechanical model of human ventricular tissue is used to simulate the effects of OM in heart failure with reduced ejection fraction (HFrEF).

Functional assessment of coronary artery disease by intravascular ultrasound and computational fluid dynamics simulation

Revista Portuguesa de Cardiologia, 2014
Clinical trials have shown that functional assessment of coronary stenosis by fractional flow reserve (FFR) improves clinical outcomes. Intravascular ultrasound (IVUS) complements conventional angiography, and is a powerful tool to assess atherosclerotic

TCT-529 The correlation between Quantitative Flow Ratio (QFR) and Fractional Flow Reserve (FFR)

Journal of the American College of Cardiology, 2016
Fractional Flow Reserve (FFR) is an indispensable device to identify coronary stenoses causing myocardial ischemia. But FFR is more invasive than coronary angiography and require additional cost, time and efforts.
