Aims: Coronary microvascular dysfunction (CMD) is a heterogeneous condition defined by reduced coronary flow reserve (CFR). The new index 'microvascular resistance reserve' (MRR) has been developed, but its role is unclear. We investigate the relationships between functional indices in ANOCA (angina and non-obstructive coronary arteries) patients and evaluate the hemodynamic features of different CMD subtypes.

Background: Angiography-derived microcirculatory resistance (AMR) is proposed as a novel, pressure- temperature-wire-free and less-invasive method to evaluate coronary microvascular dysfunction (CMD). This study aims to examine the prognostic role of CMD assessed by AMR in predicting adverse events in acute coronary syndrome (ACS) patients with chronic kidney disease (CKD).
Methods: This retrospective cohort study included ACS with CKD patients in the China-Japan Friendship Hospital from January 2016 to November 2022.

Background: The presence of hepatic steatosis (HS) is a crucial histological parameter for evaluating the suitability of liver transplantation. However, to date, no studies have used contrast-enhanced ultrasonography (CEUS) to diagnose and grade HS in brain-dead donors. This study aimed to detect and quantify hepatic microcirculatory perfusion in brain-dead donors using CEUS and to assess the utility of CEUS in the diagnosis and grading of HS.

Introduction: Microcirculatory alterations are predictive of poor outcomes in patients with shock and after cardiac arrest in animal models. However, microcirculatory alterations during human cardiac arrest have not yet been studied.
Methods: We prospectively included adult patients receiving resuscitation after witnessed out-of-hospital cardiac arrest.

Introduction: Little is known about the day-to-day variability of different skin microcirculation parameters, and how this variability is influenced by age and sex. The aim was to examine the day-to-day variability of microcirculatory parameters in relation to age and sex.
Methods: The cutaneous microcirculation was measured using a fiber optic probe integrating laser Doppler flowmetry (LDF) and diffuse reflectance spectroscopy (DRS) to measure oxygen saturation, red blood cell (RBC) tissue fraction, speed-resolved and conventional perfusion.
