Comparison of the new OPS Imaging technique with intravital microscopy: Analysis of the colon microcirculation [PDF]

, 2002
Background. The OPS imaging technique has been introduced for in vivo assessment of microcirculation in humans. The aim of this study was to validate the new technique against intravital fluorescence microscopy (IFM) for the visualization of colon ...

Dissecting the Effects of Ischemia and Reperfusion on the Coronary Microcirculation in a Rat Model of Acute Myocardial Infarction. [PDF]

PLoS ONE, 2016
Microvascular injury (MVI) after coronary ischemia-reperfusion is associated with high morbidity and mortality. Both ischemia and reperfusion are involved in MVI, but to what degree these phases contribute is unknown.

Integrative Physiology of Coronary Microcirculation.

The Japanese Journal of Physiology, 1999
Coronary microvessels play a crucial role for mechanoenergetic interaction between blood flow and myocardial function, which is not uniform transmurally. Thus, highly organized vascular regulations are required for matching local blood flow with myocardial energy requirement.

Assessment and Treatment for Coronary Microvascular Dysfunction by Contrast Enhanced Ultrasound

Frontiers in Cardiovascular Medicine, 2022
With growing evidence in clinical practice, the understanding of coronary syndromes has gradually evolved out of focusing on the well-established link between stenosis of epicardial coronary artery and myocardial ischemia to the structural and functional

Effects of salvianolate on microcirculatory disturbance in patients with stable coronary heart disease: study protocol for a randomized controlled trial

Trials, 2021
Background Obstruction of coronary microcirculation can lead to myocardial ischemia and poor prognosis. Salvianolate exerts cardiovascular protection at cellular levels.

Invasive assessment of the coronary microcirculation in the catheter laboratory

, 2015
Historically much of our understanding of the coronary circulation has been centered towards the epicardial vessels. However, recent work has highlighted the importance of the coronary microcirculation across a broad spectrum of clinical conditions in ...

Activation of adenosine A2A but not A2B receptors is involved in uridine adenosine tetraphosphate-induced porcine coronary smooth muscle relaxation

Journal of Pharmacological Sciences, 2019
Activation of both adenosine A2A and A2B receptors (A2BR) contributes to coronary vasodilation. We previously demonstrated that uridine adenosine tetraphosphate (Up4A) is a novel vasodilator in the porcine coronary microcirculation, acting mainly on A2AR
