Filter by:The purpose of this study is to compare short-term (6-month Dual Anti Platelet Therapy(DAPT) followed by clopidogrel monotherapy) vs. standard long-term dual antiplatelet strategies (24-month DAPT followed by aspirin monotherapy) on clinically relevant bleeding complications (Bleeding Academic Research Consortium(BARC) type 2, 3, or 5)31 in patients after zotarolimus-eluting stent implantation.
The study tests if intense light could be a potential therapy in humans after myocardial infarction by inducing Per2.
Primary purpose: To evaluate the evolution in time of the antiaggregant platelet effect of sertraline (SSRI) compared to placebo in depressive patients with ACS (Acute Coronary Syndrome) and treated as recommended by a double antiplatelet therapy, aspirin and clopidogrel. Hypothesis: The benefits of SSRIs observed in depressive patients with ACS are related to an antiplatelet effect.
In a prospective international multicenter observational study, 1080 stable chest pain patients (REALITY Advanced registry of CCTA patients) with the suspected chronic coronary syndrome will be enrolled. All of them will undergo computed tomography angiography, CMR and/ or SPECT, and Echo. One of the cohorts will be examined with multimodality invasive imaging including quantitative coronary angiography, FFR, QFR with or without further percutaneous coronary intervention, OCT, and some of them - with IVUS, VH-IVUS. The plaque size and relevant stenosis, a composition of the atherosclerotic lesion, major adverse cardiovascular events (all-cause death, death from cardiac causes, myocardial infarction, or rehospitalization due to unstable or progressive angina, ischemia-driven revascularization) will be judged to be related to either originally treated (culprit) lesions or untreated (non-culprit) lesions. Moreover, the clinical potential of both non-invasive and invasive imaging, as well as anatomical vs functional modalities in two real-world patient flows, will be estimated with the special focus on the natural progression of atherosclerosis, clinical outcomes, and safety (contrast-induced nephropathy, radiocontrast-induced thyroid dysfunction, and radiation dose). The diagnostic accuracy will be analyzed. The follow-up period will achieve 12 months prospectively with collected clinical events and imaging outcomes which will be determined at the baseline and 12-month follow-up. The independent ethics expertise will be provided by the Ural State Medical University (Yekaterinburg, Russia) and Central Clinical Hospital of the Russian Academy of Sciences (Moscow, Russia). The monitoring of the clinical data with imaging as well as further CoreLab expertise (expert-level post-processing multimodal imaging software of Medis Imaging B.V., Leiden, The Netherlands) will be provided by De Haar Research Task Force, Amsterdam-Rotterdam, the Netherlands. FFR-CT is scheduled to be assessed by the ElucidVivo Research Edition software from Elucid Bio, Boston, MA, U.S.A. The REALITY project is a part of the JHWH (Jahweh) International Advanced Cardiovascular Imaging Consortium. The main objective of the Consortium that is uniting international efforts of both Academia and Industry is a synergistic development of the advanced machine-learning imaging software in order to integrate benefits of both non-invasive and invasive imaging providing the daily clinical practice with the robust tool for the anatomical and functional examination of coronary atherosclerosis, PCI-related arterial remodeling, and relevant myocardial function.
The devices used in this observational registry are the Osprey Medical Contrast Monitoring System (CMS) and the Osprey Medical AVERT Reflux Reduction System. Both products have CE Mark designations. The purpose of this registry is to evaluate the usability characteristics of the combined Osprey Medical AVERT System and the Contrast Monitoring System during normal clinical use.
This study evaluates the myocardial protection against perioperative ischemia comparing two standard anesthetic regimes in diabetic patients undergoing elective cardiac surgery. Half of the patients will receive volatile anesthesia while the other half will receive total intravenous anesthesia. Primary and secondary outcome parameters will be assessed after induction of anesthesia, at the end of the procedure and postoperative day 1 to 3.
The purpose of the study is to investigate the extent of ischemia and left ventricular function in cardiovascular magnetic resonance (CMR), as well as patency of coronary arteries and grafts in coronary computed tomography angiography at 12 months follow up in patients with advanced coronary artery disease treated with percutaneous coronary intervention with the implantation of bioresorbable scaffolds or coronary artery bypass graft surgery. Additionally, the clinical results of the two methods of revascularization will be carried out annually up to 5 years.
The purpose of this pilot study proposal is to test the ability of Transluminal Flow Encoding (TAFE) to evaluate vessel specific ischemia in patients with a clinical indication for invasive coronary angiography (ICA) with fractional flow reserve (FFR) measurements for suspected coronary disease.
The purpose of this study is to investigate the effects of febuxostat on coronary plaque volume in patients with chronic stable angina and hyperuricemia.
The purpose of this study is to determine whether pharmacologic lowering of low density lipoprotein cholesterol (LDL), initiated in healthy young to middle aged adults can eliminate or markedly reduce the composite endpoint of incident all cause mortality, myocardial infarction, stroke or coronary revascularization.
