Blood Flow Changes in Femoral-popliteal Bypass Grafts After Neuromuscular Electrical Stimulation (NMES).

Within the vascular department at Charing Cross Hospital, there is an on-going NIHR-funded trial looking at the haemodynamics and clinical outcomes of patients with intermittent claudication. The aim of the study is to find out whether the neuromuscular electrical stimulation (NMES) device, REVITIVE, can improve the time-averaged mean velocity (TAMV) …

Phase N/A

A Clinical and Histological Analysis of Mesenchymal Stem Cells in Amputation

This is a phase I single center open label trial study that will enroll sixteen patients requiring semi-elective lower extremity major amputation within a 30 day period for non-infectious complications related to critical limb ischemia (CLI). After enrollment patients will be scheduled for amputation 7 days after MSC administration. The …


Dose Response to the Norepinephrine Precursor Droxidopa in Hypotensive Individuals With Spinal Cord Injury

Interruption of sympathetic cardiovascular autonomic regulation following spinal cord injury (SCI) is associated with significantly reduced plasma norepinephrine (NE) levels, hypotension and orthostatic hypotension (OH), particularly in individuals with high cord lesions. Although the incidence of hypotension is reported to be as high as 70% in persons with cervical lesions …

The Role of microRNA-210 in Regulating Oxidative Stress in Patients With PAD

The investigators will randomize 180 PAD patients that undergoing a revascularization operation in two groups: (1) an endovascular procedure or (2) an open bypass procedure. They are also planing to recruit 50 non-PAD healthy control subjects. The goal is to answer the main hypothesis that miR-210 gene expression is a …
