Sign Up to like & getrecommendations! Published in 2022 at "Catheterization and Cardiovascular Interventions"
DOI: 10.1002/ccd.30174
Abstract: The index of microvascular resistance (IMR) is an established tool to assess the status of coronary microcirculation. However, the need for a pressure wire and hyperemic agents have limited its routine use and have led… read more here.

DOI: 10.1002/ccd.30526
Abstract: Noninvasive methods of estimating invasively measured fractional flow reserve (FFRinvasive) are actively being explored, aiming to avoid the use of an invasive pressure wire and the administration of hyperemia‐inducing drugs. Coronary angiography‐derived FFR (FFRangio) has… read more here.

DOI: 10.1002/clc.23999
Abstract: Coronary microvascular dysfunction is crucial in determining myocardial ischemia; however, the relationship between epicardial coronary diameter stenosis (DS) and the index of microcirculatory resistance (IMR) remains unclear. We sought to explore the distribution of coronary… read more here.
