Filter by:ADAPTABLE is a pragmatic clinical trial in which 15,000 patients who are at high risk for ischemic events will be randomly assigned in a 1:1 ratio to receive an aspirin dose of 81 mg/day vs. 325 mg/day. Study participants will be enrolled over 38 months. Maximum follow-up will be 50 months. The purpose of the study is to identify the optimal dose of aspirin for secondary prevention in patients with Atherosclerotic cardiovascular disease (ASCVD). The primary endpoint is a composite of all-cause death, hospitalization for MI, or hospitalization for stroke. The primary safety endpoint is hospitalization for major bleeding with an associated blood product transfusion.
The purpose of this study is to evaluate the effect of preoperative remote ischaemic preconditioning (RIPC) on organ damage and the functional characteristics of arteries in patients undergoing vascular surgery. In addition, we investigate the connection between RIPC and changes in the functional characteristics of arteries and low molecular weight metabolites.
Background: Effectiveness of Percutaneous transluminal angioplasty and stenting (PTAS) on prevention of events of stroke and death in patients with symptomatic intracranial atherosclerosis (ICAS) is controversial. Aim: to determine whether PTAS plus medical treatment (MT) are superior to MT alone in preventing events of stroke and death in patients with symptomatic ICAS. Methods: The investigators will carry out a randomized controlled trial in 3 hospitals in China. A total of 198 patients with ICAS will be randomized into 2 groups: PTAS+MT and MT group. All patients will receive aspirin (100 mg daily) and clopidogrel (75 mg daily) immediately after randomization, and patients in PTAS+MT group will receive surgery within 5 days after randomization. The patients will be followed up for 1 year after randomization and assessed for events of stroke and death at 30 days and 1 year after randomization, the incidence of recurrent ischaemic stroke in the stenting-involved vascular territory at 30 days and 1 year after randomization, incidence of in-stent restenosis at 1 year after randomization,etc.
Patients undergoing semi-elective lower extremity major amputation from complications associated with atherosclerotic limb ischemia will received intra-muscular injections of allogeneic Mesenchymal Stromal Cells in the leg above and below the point of amputation to prevent ischemic wound complications after surgery and decrease the incidence of revision and further amputation. Cohort Groups 1-4 will serve as controls.
The aim of the study is to evaluate the efficacy and safety of sirolimus-eluting coronary stent "Calypso" (Angioline, Russia) in comparison with everolimus-eluting coronary stent "Xience" (Abbott Vascular, USA)
The purpose of this study is to see if ETC-1002 (bempedoic acid) is safe and well-tolerated versus placebo in patients with high cardiovascular risk and elevated LDL cholesterol that is not adequately controlled by their current therapy.
This study was to investigate the Effect of Sitagliptin, a dipeptidyl peptidase-4 inhibitor, on Progression of Coronary Intermediate Lesion.
The purpose of the study is to assess short and long term outcomes of acute coronary syndrome in patients with non obstructive coronary atherosclerosis, to optimize the algorithm for diagnosis and to evaluate its effectiveness
This study is a non-randomized prospective cohort study that will define the rate of index atherosclerotic plaque development in adults with a prior coronary artery calcium (CAC) score of 0 given prior CAC zero > 5 years previous. Ancillary testing of serum, whole blood, and endothelial dysfunction will be performed to investigate any detectable systemic processes that predict CAC development.
The combination of aspirin and dipyridamole, two antiplatelet drugs, is approved in Italy for the secondary prevention of cerebral embolism in patients with carotid atherosclerosis. Besides antiplatelet activity, Dipyridamole has additional pharmacological action, including vasodilation and antioxidant properties. A role for oxidative stress has been suggested in acute cerebrovascular disease. In this study the investigators want to test the in vivo antioxidant activity of dipyridamole in patients who are candidate to take the drug under approved conditions of the Italian Drug Regulation Agency, i.e. secondary prevention of TIA/Stroke in patinets with carotid stenosis (>= 70%). To test the hypothesis that dipyridamole acts as antioxidant in vivo, oxysterols (products of cholesterol autoxidation) and vitamin E are measured in plasma before and after 6 months therapy after carotid endoarterectomy. Since dipyridamole is approved as combination preparation with aspirin, a control group of patients taking aspirin alone is enrolled. Outcome measures: plasma biomarkers (oxysterols and vitamin E) change at two time points: baseline and 6-months therapy.
