Vascular Endothelial Function
Vascular Endothelial Function
Brachial artery flow-mediated dilation (FMD) is a non-invasive clinical measure to evaluate nitric oxide mediated vascular endothelial function. Our laboratory uses Hokanson rapid inflation device and Aloka prosound alpha 7 ultrasound system connected with semi-automated vascular wall tracking software, Cardiovascular Suite (Quipu, Italy).
Central Artery Stiffness
Central Artery Stiffness
Pulse wave velocity (PWV) and Augmentation index (AIx) are non-invasive clinical measures to assess arterial stiffness in humans.
Our laboratory evaluates aortic PWV and AIx using SphygmoCor Xcel system.
Carotid Artery Stiffness
Carotid Artery Stiffness
Our laboratory measures carotid artery compliance, distensibility, and beta-stiffness index to assess carotid artery stiffness, an independent indicator for cardiovascular disease, using Aloka alpha 7 ultrasound system connected with semi-automated vascular wall tracking software, Cardiovascular Suite (Quipu, Italy).
Peripheral Artery Stiffness
Peripheral Artery Stiffness
To assess peripheral artery stiffness, our laboratory measures arm and leg pulse wave velocity (PWV) using Doppler Flowmeters (Parks Medical Electronics, USA). Data collected by Doppler Flowmeters are processed by PowerLab data acquisition system (PL3504, ADInstruments, Australia) and its signal-processing software (LabChartPro V8, ADInstruments, Australia).
Celebral Blood Flow
Celebral Blood Flow
Our laboratory employs PortaLite (Artinis medical system, Netherlands), a near-infrared spectroscopy (NIRs)-based measurement device, to assess prefrontal cortex blood flow.Â
Cardiac Autonomic Nerve Function
Cardiac Autonomic Nerve Function
To evaluate resting stress level and autonomic nerve function including Heart Rate Variability (HRV), our laboratory employs Vital Scan HW10A system (Medeia, USA).
Pulmonary Function
Pulmonary Function
Our laboratory performs comprehensive pulmonary function test (PFT) using Quark PFT system (Cosmed, Italy) with a respiratory chamber. The main parameters we measure are as follows: Forced Vital apacity (FVC), Forced Expiratory Volume in one second (FEV1), and Diffusing Capacity of the Lungs for Carbon Monoxide (DLco).
