Microcirculatory dysfunction in hypertrophic cardiomyopathy with chest pain assessed by angiography-derived microcirculatory resistance [PDF]

Scientific Reports
Chest pain, a common initial symptom in hypertrophic cardiomyopathy (HCM) patients, is closely linked to myocardial ischemia, despite the absence of significant coronary artery stenosis.

A hemorheological perspective on coronary microvascular dysfunction: Association of erythrocyte parameters with angiography-derived coronary microcirculatory resistance. [PDF]

PLoS ONE
BackgroundCoronary microvascular dysfunction (CMD) contributes to myocardial ischemia in patients both without obstructive coronary artery disease (e.g., MINOCA/INOCA) and in those with co-existing epicardial stenosis.

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

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 ...

Angio-Based Index of Microcirculatory Resistance for the Assessment of the Coronary Resistance: A Proof of Concept Study [PDF]

Journal of Interventional Cardiology, 2020
Background. The study of coronary microcirculation has gained increasing consideration and importance in cath lab. Despite the increase of evidence, its use still remains very limited.

The role of the angiography-derived index of microcirculatory resistance in the prognosis of patients with dilated cardiomyopathy. [PDF]

Quant Imaging Med Surg, 2023
The coronary angiography-derived index of microcirculatory resistance (caIMR) is a novel noninvasive method to assess coronary microvascular dysfunction (CMD). However, the association between caIMR and the prognosis of patients with dilated cardiomyopathy (DCM) is unclear. We aimed to explore the role of the caIMR in evaluating the outcome of patients

Index of Microcirculatory Resistance Measured during Intracoronary Adenosine-Induced Hyperemia

Journal of Interventional Cardiology, 2020
Background. The index of microcirculatory resistance is an invasive measure of coronary microvascular function that has to be calculated during maximal hyperemia, classically achieved with intravenous adenosine (IV). The aim of this study was to evaluate

Diagnostic relevance of angiography-derived coronary microcirculatory resistance in sudden cardiac death. [PDF]

Quant Imaging Med Surg
Obstructive coronary disease remains a leading cause of sudden cardiac death (SCD). The management of SCD therefore involves coronary angiography. Our aim was to evaluate whether the non-hyperemic angiography-derived microcirculatory resistance index (NH-IMRangio) could be an easy-to-use tool for identifying patients with electrical heart disease (EHD)

Effects of SGLT2 inhibitors on angiography-derived coronary microcirculatory resistance and clinical outcomes in patients with coronary heart disease and type 2 diabetes: A cohort study [PDF]

Diabetology & Metabolic Syndrome
Background Coronary microvascular dysfunction (CMD) is prevalent in patients with coronary heart disease (CHD) and Type 2 Diabetes (T2DM). Sodium-glucose cotransporter 2 inhibitors (SGLT2i) have cardioprotective effects, however, their impact on ...

Angiography-derived assessment of coronary microcirculatory resistance in patients with chronic total occlusion. [PDF]

Heart Vessels
Abstract Coronary microvascular dysfunction (CMD) represent a crucial and often underdiagnosed cause of myocardial ischemia and dysfunction. It is closely linked to the prognosis of patients with coronary artery disease.

Prognostic impact of angiography-derived index of microcirculatory resistance in patients with dilated cardiomyopathy. [PDF]

Int J Cardiol Cardiovasc Risk Prev
Coronary microvascular dysfunction (CMD) has recently been associated with adverse cardiovascular events in patients with heart failure. We investigated the relationship between late gadolinium enhancement (LGE) and CMD, as well as the prognostic value of CMD in predicting long-term prognosis in patients with dilated cardiomyopathy (DCM).Patients with ...
