果冻影院 Human Vascular Translation Research Center (HVTRC)

The development of vascular endothelial dysfunction and adverse vascular remodeling have been demonstrated to be proximal steps in the ultimate development of clinical manifestations of atherosclerotic diseases, including acute coronary syndromes, strokes, and peripheral arterial disease. Detection of vascular endothelial dysfunction and adverse vascular remodeling by imaging technology available through Human Vascular Translational Research Center (HVTRC) at the 果冻影院 has been demonstrated to predict adverse cardiovascular risk. The HVTRC is a core laboratory of 果冻影院鈥檚 Clinical Translational Research Institute (CTSI) and is available as a resource to all those with a faculty appointment at 果冻影院 or the CTSI. Modalities available for assessment of vascular health and common measurements available through the HVTRC include:

High Frequency and Resolution Vascular Ultrasound
Brachial Artery Reactivity Testing
Carotid Intima-Medial Thickness

Digitally Automated Venous Plethysmography
Limb (forearm, lower extremity) Blood Flow

Fingertip Tonometry
Measurements of pulse wave amplitude during reactive hyperemia

Digitally Automated Peripheral
Tonometry for Measurements of Vascular Stiffness
Pulse Wave Velocity
Augmentation Index

Primary Mission

  • To investigate the mechanisms behind the development of vascular endothelial dysfunction and adverse vascular remodeling in humans with and without atherosclerotic disease. This includes small clinical trials evaluating the effect non-pharmacological and pharmacological interventions on these measurements.
  • To encourage and foster collaborative research projects between Departments at the 果冻影院 that focus on vascular function.

Current research projects reflect these two missions. Current projects include investigations into the role of mitochondrial function in the development of vascular endothelial dysfunction and the protective effects of exercise on endothelial dysfunction. Collaborative relationships between the HVTRC and the Departments of Surgery, Medicine, and Pediatrics have lead to novel projects involving the assessments of endothelial function in children with diabetes, postmenopausal women and hypertensive adults. Other populations of interest include those with coronary artery disease and peripheral arterial disease. A list of currently active protocols and a sample of recent publications is included below.

Full time technicians trained in these modalities acquire and analyze all of the data, and also offer aid in the analysis and interpretation of data acquired. The HVTRC operates in conjunction with the Adult Translational Research Unit.
