Filter by:The purpose of this study is to demonstrate the utility of the FlowMet™ device in the assessment of perfusion in subjects suspected of or being treated for critical limb ischemia, in comparison to other gold standard technologies, such as ankle brachial pulse index (ABI), skin perfusion pressure (SPP), toe brachial pulse index (TBI), transcutaneous oxygen tension (TcP02), and angiography currently in use in the clinic.
This study is being conducted as an extension of the phase II clinical trial SRPL/CLI/10-11/001 (NCT01484574). The CDSCO has recommended flexibility for continued clinical study in consultation with ICMR, as per recommendation of Cellular biology based therapeutic drug evaluation committee (CBBTDEC).
Compare the changes of regional cerebral oxygen saturation during midazolam or dexmedetomidine sedation for spinal anesthesia in the elderly patients who undergoing femur surgery.
The purpose of project is to answer fundamental questions about the mechanisms underlying mental stress ischemia in patients with coronary artery disease, mood disorders, or both, and to identify potential biomarkers and psychosocial risk factors associated with this condition. To achieve this goal, investigators will use cutting-edge cardiovascular and functional neuroimaging tools to study mental stress ischemia in a carefully controlled laboratory setting in subjects recruited from four patient populations: 1) patients who recently sustained a myocardial infarction; 2) patients undergoing non-emergent invasive coronary angiography (with and without known coronary artery disease); 3) patients with a diagnosis of major depressive disorder; and 4) patients with a diagnosis of bipolar 1 or bipolar 2 disorder.
This is a phase 1, blinded-outcome, randomized, placebo controlled study to investigate the safety and feasibility of super-selective intra-arterial administration of verapamil and citicoline immediately following successful endovascular thrombectomy as a potential neuroprotective synergistic therapeutic strategy in emergent large vessel occlusion stroke. This trial represents the first time that citicoline will be evaluated in human subjects as a superselectively administered neuroprotective agent administered in an acute time frame as an adjunct to intra-arterial thrombectomy. Furthermore, it will represent the first trial to evaluate combinational therapy for acute stroke neuroprotection.
Laparoscopic partial nephrectomy (LPN) is often reserved for patients with a small peripheral tumour, in the hands of an experienced surgeon since it demands a high degree of endoscopic skill. Renal vessel clamp for vascular control is a required step during standard LPN. However, this creates a time limiting step for the surgeon and induces renal injury via warm ischemia and reperfusion injury. This novel approach can substantially reduce renal injury during LPN via superselective embolization of level II renal arteries pre-operatively. This technique facilitates the performance of a clamp-less, zero-ischemia LPN, significantly simplifying the procedure by remove time thresholds within which to perform tumor excision. The preliminary results are promising; however, there is a need for further corroboration of their results, in addition to a randomized controlled trial comparing this modified, zero ischemia technique with standard LPN.
The purpose of this investigation is to compare subjects at high risk for silent myocardial ischemia in the placebo group to subjects at high risk for silent myocardial ischemia in the ranolazine group to determine if ranolazine can be used as a treatment to decrease silent myocardial ischemia (SMI). Subjects at high risk for silent myocardial ischemia are defined in this protocol as diabetics with stable ischemic heart disease. This study will look at the impact ranolazine treatment has on biomarkers that have been shown to be highly associated with increased risk of morbidity and mortality in relation to SMI. If the hypothesis is correct, further studies can be conducted to determine if treatment with ranolazine has impact on long-term outcomes such as hospitalizations, myocardial infarction, congestive heart failure or sudden cardiac death.
Before initiating the full randomized study, a Pilot Safety Phase will be performed. In this phase the composition of cells administered via the Biosense Webster MyoStar NOGA Injection Catheter System will be tested. The randomized portion of the study will be conducted after a full review of the safety data from the pilot Phase by the Data safety monitoring board. Following the Pilot Phase of five (5) Fifty (50) patients scheduled to undergo cardiac catheterization and meeting all inclusion/exclusion criteria will be evaluated at baseline. Patients will be randomized in a 2:2:1 ratio to one of three Treatment Strategies.
This clinical trial to study the Safety and Efficacy of Autologous Mesenchymal stem cells in critical limb ischemia.
Left Ventricular Assist Devices are commonly used to assist failing hearts as a bridge to transplantation or for long-term support. The purpose of the MESenchymal stem cell therapy and Left Ventricular Assist Device program is to improve heart function with stem cell therapy and attempt to wean patients from HeartMate Left Ventricular Assist Device.
