Filter by:The purpose of this study is to assess whether the use of physiology parameters as guidance post-percutaneous coronary interventions (PCI) is associated with less risks of target vessel failure (TVF) and angina-related events than standard angiographic guidance.
Early diagnosis of NSTEMI and UA patients is mainly through the construction of machine learning model.
This is a national registry study to determine genetics risk factors and serial biomarkers of Acute Coronary Syndrome.
The EMERALD II study is a multinational, multicenter, and retrospective study. ACS patients who underwent CCTA from 1 months to 3 years prior to the event will be retrospectively identified. Plaques in the non-culprit vessels will be regarded as a primary control group.
Serum uric acid level is a commonly measured biomarker. The association between serum uric acid level and the risk of developing cardiovascular diseases has been observed in some studies, while others showed controversial results. Estimation of this association may help to predict cardiovascular outcomes and may guide new treatment strategies. The hypothesis is that increased serum uric acid level is associated with a range of cardiovascular diseases.
Approximately 5 to 8% of patients undergoing percutaneous coronary interventions requires chronic anticoagulant therapy due to atrial fibrillation or other clinical entities. There are many possible different combinations of the antithrombotic therapy after stent implantation in these patients. Aim of this observational study is to evaluate the real world antithrombotic treatment in patients requiring anticoagulant therapy undergoing stent implantation and to compare the clinical outcome of patients treated with new oral anticoagulant drugs compared to warfarin. The study is prospective, performed in different Italian hospitals and aimed to enroll 1080 patients with a 1 year follow up
The current study sought to evaluate the clinical relevance of iFR-guided strategy in real world clinical practice using unrestricted study population from stable angina to acute coronary syndrome including acute ST-segment elevation myocardial infarction. Previous abundant historical data of FFR-guided strategy will be also included as historical control to validate the iFR-guided strategy.
Study aim : To compare a novel strategy of lesion preparation with noncompliant balloons before implantation of BVS (Bioresorbable Vascular Scaffold). Hypothesis: Predilatation with non-compliant balloons could facilitate optimal deployment of BVS. By achieving good scaffold apposition a need for post-dilatation could be significantly reduced. This is expected to result in better short- and long-term outcomes.
The purpose of this study is to collect additional safety and effectiveness data for on the Biosensors BioFreedom™ BA9 Drug Coated Coronary Stent in patients with native, de novo coronary artery disease.
Autoimmune diseases are diseases in which inappropriate immune responses that have the capability of harming host cells play an important role. Evidence suggests that the presence of certain autoimmune diseases such as rheumatoid arthritis or systematic lupus erythematosus increase the risk of cardiovascular disease (CVD). However, this evidence is inconsistent for autoimmune disorders and no systematic approach has been previously used to study the relationship between a range of common autoimmune disorders and specific forms of cardiovascular diseases such as myocardial infarction, intracerebral and subarachnoid haemorrhage, or venous thrombosis. The investigators will use linked electronic health records to investigate whether commonly diagnosed autoimmune disorders are associated with increased risk of CVD development and whether effects differ in men and women and change with age.
