Use of the Instantaneous Wave-free Ratio or Fractional Flow Reserve in PCI [PDF]

, 2017
BACKGROUND: Coronary revascularization guided by fractional flow reserve (FFR) is associated with better patient outcomes after the procedure than revascularization guided by angiography alone.

Adipose‐derived small extracellular vesicles exacerbate microvascular dysfunction in heart failure with preserved ejection fraction via mmu‐miR‐582‐3p‐mediated Rap1b suppression

Interdisciplinary Medicine, EarlyView.
This study reveals that small extracellular vesicles (sEVs) from visceral fat compromise coronary microcirculation in a mouse model of heart failure with preserved ejection fraction (HFpEF). The SGLT2 inhibitor canagliflozin emerges as a therapeutic strategy, improving cardiac function and endothelial health.

Determinants of renal flow reserve in adult patients with and without renal artery stenosis

Physiological Reports
Renal flow reserve (RFR) is a hemodynamic measure of renal microvascular function and may help identify patients with renal artery stenosis (RAS) who could benefit from revascularization.

Nitrosylated hemoglobin levels in human venous erythrocytes correlate with vascular endothelial function measured by digital reactive hyperemia. [PDF]

PLoS ONE, 2013
Impaired nitric oxide (NO)-dependent endothelial function is associated with the development of cardiovascular diseases. We hypothesized that erythrocyte levels of nitrosylated hemoglobin (HbNO-heme) may reflect vascular endothelial function in vivo.

Mesenteric Vascular Dysregulation and Intestinal Inflammation Accompanies Experimental Spinal Cord Injury

, 2016
Cervical and high thoracic spinal cord injury (SCI) drastically impairs autonomic nervous system function. Individuals with SCI at thoracic spinal-level 5 (T5) or higher often present cardiovascular disorders that include resting systemic arterial ...

Exploring the Dynamics of Ischemia and Reactive Hyperemia With Skeletal Muscle Blood Oxygen Level Dependent MRI in Patients With Peripheral Artery Disease, Age‐Matched Controls, and Young Healthy Subjects

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Skeletal muscle blood oxygen level dependent (BOLD) MRI is a technique for assessing vascular function in peripheral limbs. In patients, however, an increased frequency of atypical response patterns has been observed, warranting investigation into its underlying causes.

Arterial spin labeling perfusion cardiovascular magnetic resonance of the calf in peripheral arterial disease: cuff occlusion hyperemia vs exercise

Journal of Cardiovascular Magnetic Resonance, 2015
BackgroundAssessment of calf muscle perfusion requires a physiological challenge. Exercise and cuff-occlusion hyperemia are commonly used methods, but it has been unclear if one is superior to the other.

Surrogate measure of gut blood flow via superior mesenteric circulation on ultrasound in adults who underwent esophagectomy: A descriptive cohort study

Journal of Parenteral and Enteral Nutrition, EarlyView.
Abstract Background Early enteral nutrition is recommended for critically ill patients. However, feeding an ischemic gastrointestinal tract with enteral nutrition may lead to gut necrosis. Although gut tolerance of enteral nutrition is assessed by various symptoms, none of them provide conclusive evidence of gut ischemia. We investigated the blood flow
