Active clinical trials for "Coronary Disease"

The investigators propose to develop a computational framework involving a novel automatic image segmentation algorithm based on CTA images, an artery model reconstruction algorithm for stenosis detection, and quantification of severity of stenosis in terms of area stenosis.

Prospective, non-randomized, multi-center study assessing the long term safety and efficacy of the self expandable sirolimus eluting Xposition S stent in the treatment of unprotected left main coronary artery disease.

Biomime stent is a novel sirolimus-eluting stent (SES) (Meril Life Sciences Pvt. Ltd., Gujarat, India) with an ultra-thin stent platform (65 μm) and a biodegradable polymer licensed for the treatment of de novo coronary lesions. However no data regarding the efficacy and safety of this stent in an "all-comers" patient population treated with percutaneus coronary interventions (PCI) have been published so far. In this registry the investigators aimed to collect clinical and angiographic information about an extensive "all-comers" employ of this novel stent.

Clinical evaluation of the Orsiro LESS in subjects requiring coronary revascularization with Drug Eluting Stents (DES). Along with it, an explanatory (hypothesis-finding) problem will be investigated, whether the patient's body inflammation status correlates with the clinical outcome.

Clinical evaluation of the Orsiro LESS in subjects requiring coronary revascularization with Drug Eluting Stents (DES). 500 subjects will be enrolled in this registry.

Aim of this study is to describe clinical and procedural characteristics of real-world population initiated on triple antithrombotic therapy (double antiplatelet therapy+anticoagulant) or double antithrombotic therapy (single antiplatelet therapy+anticoagulant) after percutaneous coronary intervention (PCI). Investigator's driven trial, retrospective (2015-2019), multicenter Italian registry. Baseline clinical characteristics as well as procedural details will be collected retrospectively. Follow-up data (minimum 6 months and maximum 5 years follow-up) will focus on combined rates of stent thrombosis and myocardial infarction (primary endpoint).

Assessment of Biomarkers in Patients with Decompensated Heart Failure and Underlying Coronary Artery Disease

Restenosis occurs for many different reasons. Over the years, many predictive clinical, biological, genetic, epigenetic, lesion-related, and procedural risk factors for restenosis have been identified. Smoking is one of most important factors, however the results were contradictory. And the genetic factors of restenosis have been studied mostly in European populations. Based on literature review, study of candidate genes for restenosis in Chinese population was insufficient. With due attention to this matter mentioned above, the investigators aim to preliminary explore genetic variation and smoking effect on clinical restenosis in patients diagnosed with after percutaneous coronary intervention in the Chinese population, with correlation analysis of factors and gene-set analysis of biological pathways related to restenosis and platelet approach were widely used in this study.

A total of 100 patients with non-ST-segment elevation acute coronary syndromes with or without diabetes mellitus will be included. All patients will undergo coronary angiography with identification of the infarct-related vessel and percutaneous revascularization with implantation of a stent/scaffold. After revascularization patients will undergo a combined positron emission tomography (PET)-coronary computed tomography (CT) protocol to quantify atherosclerotic burden (i.e. plaque volume) and activity (i.e. 18 fluorum-sodium-fluoride [18FNaF] uptake) in non-infarct related vessels, to assess calcium score (aim 1), and to quantify the acute results of PCI in the infarct-related vessel (aim 2). At 12-month follow-up, all patients will repeat longitudinal 18FNaF PET-coronary CT evaluation to characterize progression of atherosclerosis in the non-infarct related vessels (aim 1) and to quantify neointimal suppression at the site of the treated coronary segment in the infarct-related vessel (aim 2). Blood samples will be collected at baseline and 12 months for all patients. The aims of the study are: To evaluate coronary artery disease progression in acute coronary syndromes patients with and without diabetes mellitus, and to investigate the predictive value of metabolic profiles, patterns of circulating miRNAs and inflammatory mediators on coronary artery disease progression; To evaluate the progression of disease within the infarct-related vessel treated with the use of bioresorbable stent/bioresorbable polymer stents in diabetic and non-diabetic patients with acute coronary syndromes.

The primary objective was to evaluate the effect of treatment with evolocumab on the risk for cardiovascular death, myocardial infarction, stroke, hospitalization for unstable angina, or coronary revascularization, whichever occurs first, in patients with high risk coronary artery disease.
