Filter by:Patients with ischemic heart disease are often treated with multiple cardiovascular agents, including aspirin, statins, ezetimibe, Angiotensin Converting Enzyme (ACE) inhibitors or beta-blockers. Uncertainty about the optimal timing and clinical implications of administration of cardiovascular drugs still persists. The investigators will perform a pilot randomized trial to evaluate the efficacy and safety of a one daily administration of multiple drugs vs. twice daily administration.
wide range of diagnoses may present like stroke, called stroke mimics as well as transient ischemic attacks .
The goal of the study is to correlate the effect of ischemic mitral regurgitation on the outcome of STEMI patients treated with successful primary PCI using clinical data and echocardiography on presentation and during short term follow up after 3 months
Study will investigate & compare the left ventricular remodeling & systolic function between two groups of ST-elevation myocardial infarction undergoing primary per-cutaneous coronary intervention applying ischemic post-conditioning to one of them.
The primary purpose of this trial is to compare the efficacy of different doses of investigator product and comparator product in patients with acute ischemic stroke in 4.5 Hours after stroke onset, and provide a basis of drug administration for phase Ⅲ clinical trial. The secondary purpose of this trial is to compare the safety of different dose of investigational product and comparator product in patients with acute ischemic stroke in 4.5 hours afterstroke onset .
Study drug and dosage form : Umbilical cord-derived mesenchymal stem cells (HB-MSC1) Dose and route of administration : 60 × 106 cells or 120 x 106 cells to be injected as 30 individual intramuscular injections, once at V0 within 48 hours to 2 weeks maximum after the revascularization procedure. Comparator, dose and route of administration : Placebo, injected as 30 individual intramuscular injections, once at V2 within 48 hours to 2 weeks maximum after the revascularization procedure. Study centers : 3 centers in France Study objectives : Primary: Evaluation of the feasibility and systemic and local tolerance of an implantation, via intramuscular route, of allogenic HB-MSC1, associated with a revascularization procedure, in patients suffering from critical limb ischemia (CLI). Secondary: Preliminary evaluation of efficacy and dose effect relationship of the MSC implantation in hemodynamic, anatomical and functional terms. Exploratory: Constitution of a serum bank of the patients included in the study for inflammation and auto immunity biomarkers analysis Study design : This will be a multicenter Phase IIa study, consisting in a first, open-label, ascending dose feasibility and safety stage followed by a randomized placebo-controlled feasibility, safety and preliminary efficacy stage.
CT myocardial perfusion imaging (CTP) represents one of the newly developed CT-based techniques but its cost-effectiveness in the clinical pathway is undefined. The aim of the study is to evaluate the usefulness of combined evaluation of coronary anatomy and myocardial perfusion in intermediate to high-risk patients for suspected CAD or with known disease in terms of clinical decision-making, resource utilization and outcomes in a broad variety of geographic areas and patient subgroups.
In this study, advanced techniques of myocardial nuclear magnetic perfusion scanning were used to quantitatively assess infarct size after acute myocardial infarction, saved viable myocardium, and microcirculatory obstruction area. Objectively and quantitatively evaluate early use of cardiomyopeptidin for direct PCI of ST-segment elevation myocardial infarction. After the improvement of microcirculation and increase the intervention effect of viable myocardium.
The main purpose of this study is to increase the pool of organs available for donation by performing ARP to recondition donation after cardiac death (DCD) organs prior to transplantation. We will compare the outcomes of our ARP DCD liver transplants with historical data to determine the efficacy of this treatment compared to transplantation with standard DCD and donation after brain death (DBD) organs. We will also analyze biological samples from donors and recipients and compare them with outcome data in an effort to determine if any biological markers are able to predict the quality/success of the grafts.
Skeletal muscle regenerates after injury, due to the satellite cells (SCs), the muscle stem cells that activate, proliferate, differentiate and fuse to form new myofibers. While SCs are indispensable for regeneration, there is increasing evidence for the need for an adequate cellular environment. Among the closest cellular partners of SCs are vascular cells. During muscle regeneration, endothelial cells (ECs) stimulate SC differentiation while SCs exhibit pro-angiogenic properties indicating a coupling between angiogenesis and myogenesis.The specific signaling cues controlling these relationships are still poorly characterized, specially in specific pathologic context such as limb ischemia. The investigators research aims to evaluate the role of chronic and acute lower limb ischemia on the SC status and interaction with ECs in human patients.
