Filter by:The purpose of this study is to assess safety and effectiveness of direct oral anticoagulants (DOACs) and warfarin for stroke prevention in patients with non-valvular atrial fibrillation (AF). The comparison of DOACs versus oral vitamin K antagonists, in particular warfarin, is of interest. The investigators will carry out separate population-based, matched cohort studies, using health administrative databases in seven Canadian provinces. New users of oral anticoagulants (DOACs or warfarin) for stroke prevention in non-valvular AF will be eligible to enter the cohorts. Follow-up will continue until a hospitalization or emergency department visit for a stroke. The results from the separate sites will be combined by meta-analysis to provide an overall assessment of the safety and effectiveness of the different anticoagulation regimens in stroke prevention in AF. The investigators hypothesize that DOACs and warfarin will have similar safety and effectiveness profiles.
The study design is a prospective, multicenter, single-arm, global IDE study to evaluate the safety and effectiveness of the Shockwave Medical Coronary Intravascular Lithotripsy (IVL) System in de novo, calcified, stenotic coronary arteries prior to stenting. Disrupt CAD III is being conducted as a staged pivotal study.
The main purpose of this study is to compare the myocardial protection effect of intravenous metoprolol combined with remote ischemic conditioning (RIC) and single treatment before reperfusion in Chinese patients with anterior STEMI. This study sought to find possible strategies to further improve myocardial protection in Chinese patients with anterior STEMI.
This is a Phase 2b randomized, blinded, placebo controlled study to evaluate the efficacy, safety, PK/pharmacodynamic, and immunogenicity of repeat doses of MEDI6012 in adult participants presenting with acute STEMI (ST segment elevation myocardial infarction). The study will enrol participants presenting with acute STEMI who are planned for primary percutaneous coronary intervention (pPCI). For all participants, an end of study CMR will be performed at 10-12 weeks (70-84 days following Dose 1). A subset of participants will also undergo an index and an end of study CTA.
The purpose of this study is to improve the differential diagnosis and clinical outcomes of acute coronary syndrome with non-obstructive coronary arteries, to investigate the relationship between the structural and functional state of the heart and the clinical course of the disease.
Brief Summary: This study is a prospective, multicenter, randomized, controlled trial aimed to compare the reperfusion strategy and clinical outcomes of STEMI patients treated by angiography-guided vs. OCT-guided PCI. Patients presenting STEMI with coronary artery diameter stenosis ≤70% and TIMI blood flow grade 3 at index or after thrombus aspiration are randomly assigned to either an OCT-guided group or an angiography-guided group. In OCT-guided group, stent implantation or conservative medical treatment is determined based on OCT findings. Conservative non-stenting strategy will be recommended in those with culprit plaque erosions, certain ruptures without dissection and hematoma, SCAD without obstructive stenosis. In the angiography-guided group, reperfusion strategy is decided by the operators according to the local practice. The rate of stenting during primary PCI and clinical outcomes at 1-month and 1-year are collected.
The purpose of this study is to assess safety and effectiveness of direct oral anticoagulants (DOACs) for stroke prevention in patients with non-valvular atrial fibrillation (AF). The comparison of DOACs between themselves is of interest. The investigators will carry out separate population-based, matched cohort studies, using health administrative databases in nine jurisdictions in Canada, the UK and the US. New users of DOACs for stroke prevention in non-valvular AF will be eligible to enter the cohorts. Follow-up will continue until a hospitalization or emergency department visit for a stroke. The results from the separate sites will be combined by meta-analysis to provide an overall assessment of the safety and effectiveness of the different anticoagulation regimens in stroke prevention in AF. The investigators hypothesize that different DOACs will have similar safety and effectiveness profiles.
This is a feasibility study aiming to generate pilot data on safety and efficacy of a novel anticoagulant regimen (enoxaparin bolus and prolonged infusion) compared to the local standard-of-care in opiate-treated patients undergoing primary percutaneous coronary intervention.
This is a prospective, randomized controlled trial. The aim of the study is to evaluate the impacts of a cardiac post-discharge management solution in the secondary prevention of Coronary Artery Disease (CAD).
A randomized, controlled trial to determine whether the use of ultrasound guidance for vascular access during coronary angiography or percutaneous coronary intervention (PCI) will reduce the rates of major vascular complications.
