Diagnostic Value of Angiography-Derived IMR for Coronary Microcirculation and Its Prognostic Implication After PCI

Frontiers in Cardiovascular Medicine, 2021
Background: Angiography-derived index of microcirculatory resistance (angio-IMR) is an emerging pressure-wire-free index to assess coronary microvascular function, but its diagnostic and prognostic value remains to be elucidated.Methods and Results: The ...

Remote Ischemic Preconditioning Acutely Improves Coronary Microcirculatory Function

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
Background Remote ischemic preconditioning (RIPC) attenuates myocardial damage during elective and primary percutaneous coronary intervention. Recent studies suggest that coronary microcirculatory function is an important determinant of clinical outcome.

The Index of Microcirculatory Resistance Predicts Myocardial Infarction Related to Percutaneous Coronary Intervention [PDF]

Heart, Lung and Circulation, 2011
Background— Periprocedural myocardial infarction (MI) occurs in a significant proportion of patients undergoing percutaneous coronary intervention (PCI) and portends poor outcomes. Currently, no clinically applicable method predicts periprocedural MI in the cardiac catheterization laboratory before it occurs.

Coronary flow reserve and microcirculatory resistance in patients with coronary tortuosity and without atherosclerosis

Journal of International Medical Research, 2020
Objective Coronary tortuosity may affect epicardial coronary arterial blood flow. This study aimed to investigate the effect of coronary tortuosity on coronary flow reserve and the coronary microcirculation in patients without apparent coronary ...

Neutrophil-lymphocyte ratio and platelet-lymphocyte ratio as predictors of coronary microcirculatory disease occurrence and outcome in patients with chronic coronary syndrome and no significant coronary artery stenosis [PDF]

, 2020
Introduction: Index of microcirculatory resistance assessment is an invasive method of measuring coronary microcirculation function. Association between impaired microcirculatory function and higher rate of cardiovascular events was proven.
