Filter by:The main objective is to evaluate the efficacy and safety of treatment with 2 doses (80 and 160 mg) of Revacept versus placebo in patients with stable coronary artery disease undergoing PCI.
ST elevation myocardial infarction (STEMI) patients affected by multivessels coronary artery stenosis, represent a clinical relevant problem. The management and prognosis of these patents are supported by few literature data. Therefore, in this study authors enrolled real world diabetic vs. non diabetic patients admitted for STEMI and associated to multi vessels coronary disease. Then these diabetics were divided in incretin users (6 months of incretin treatment before study enrollment) vs. never incretin users. In these patients authors studied all cause mortality, cardiac mortality, and major adverse cardiac events at 12 months follow up.
This study will retrospectively review and compare clinical outcomes between left atrial appendage occlusion with dual antiplatelet therapy versus conventional antithrombotic therapy in patients with atrial fibrillation undergoing drug-eluting stent implantation.
Background: Cardiac rehabilitation is indicated for ischemic heart disease patients; the program content of which is well described in both European and American guidelines. In contrast, literature on cardiac rehabilitation program content and efficacy in the Asian population is sparse. Methods: BeSingCardioRehab will be an intercontinental, retrospective cohort study conducted in two cardiac rehabilitation referral centers in Belgium and Singapore. The first aim is to compare the impact of phase II center-based cardiac rehabilitation on Major Adverse Cardiac Events for ischemic heart disease patients between Europe (i.e. Belgian) and Asia (i.e. Singaporean) in the long-term. The second objective is to compare the efficacy of phase II cardiac rehabilitation on short-term morbidity (assessed with the validated SMART Risk Score) between index European and Asian ischemic heart disease patients. The level of compliance of the Belgian and Singaporean cardiac rehabilitation programs to European guidelines standards will also be evaluated. Hypotheses BeSingCardiorehab will be one of the first studies assessing cardiac rehabilitation in Asia. Based on the BeSingCardioRehab study results, phase II center-based cardiac rehabilitation programs, can/will be adapted in order to improve program content and outcomes.
This is a prospective, non-randomized, open label, multi-center study including 60 patients with symptomatic ischemic heart disease with 70%-100% coronary artery stenoses and occlusions enrolled and treated in this investigational device study.
Left distal transradial approach (ldTRA) can be an attractive alternative route for left radial and right radial artery. Recently, Ferdinand Kiemeneij reported the feasibility and safety of the use of ldTRA. But, there is few studies focused on this issue. Therefore, the purpose of this prospective observational study is to assess the feasibility and safety of the ldTRA for CAG and PCI.
Cardiac computed tomography (CCT) is one of the standard non-invasive imaging techniques allowing imaging of the heart and coronary arteries with a high temporal and spatial resolution. The high sensitivity and negative predictive value (NPV) of coronary CT angiography (CCTA) make it a valuable tool in the assessment of coronary artery disease (CAD) in patients with low to intermediate risk for CAD, especially to rule out CAD. This risk stratification can be done with help of multiple different risk-calculators (e.g. the updated Diamond-Forrester model by Genders et al. 2012). These calculators take different variables into account, e.g. advanced age, gender, blood pressure, diabetes mellitus (DM), lipid profile and smoking. The aim of CCTA is a high diagnostic accuracy, which depends on both optimal intravascular enhancement (in Hounsfield Units; minimal 325 HU) and contrast-to-noise ratio (CNR). Optimal intravascular enhancement and CNR depend on different factors such as scan technique (e.g. tube voltage, tube potential), parameters of the administered contrast material (CM) and patient related factors (e.g. cardiac output (CO), body weight (BW)). Patients with cardiac diseases often have multiple risk factors for developing contrast induced nephropathy (CIN), e.g. diabetes mellitus, advanced age, hypertension and chronic kidney disease. Although the relationship between CTA and CIN has recently come to discussion (AMACING trial; Nijssen et al. 2017), it is still desirable to minimise the CM volume used in these patients. One method to reduce the CM volume is to personalise the injection protocols. The personalisation of injection protocols to the individual patient is gaining more attention in the field of CT imaging. The goal is to individualise the injection protocols to a level, where the patient only receives the minimal amount of CM needed to acquire a diagnostic scan, while maintaining a diagnostic image quality. Many techniques are available and have been studied, e.g. adjustment of CM volume to scan protocol, CO, lean body weight (LBW) and BW. However, no data is available on which of these is the most beneficial method for the personalisation of CM injection protocols. Therefore, the aim of this study is to assess the performance of three different personalized injection protocols (based on CO, LBW and BW) in CCTA with regard to image quality in comparison to previously used protocols in our department. We hypothesize that the personalized injection protocols will be non-inferior, provide a homogenous coronary enhancement (less non-diagnostic scans) in patients, and will account for a reduction of CM volume in our department in comparison to the previously used protocols.
This study aims to evaluate the psychometric properties of a newly developed FFQ specified for northern Chinese CHD and their high risk patients (CHD-FFQ). The psychometric properties include test-retest reliability, content validity, convergent validity, discriminant validity, concurrent validity and predictive validity. Particularly, this study will measure the physiological indicators, including plasma lipid profile (i.e. TG, TC, HDL-C, LDL-C), BG, BP and BMI twice at baseline and the end. The level of these physiological indicators will be compared with the fat intake measured by the CHD-FFQ, i.e. the baseline intake to test its convergent validity. It is also expected to predict the diet-related progression of CHD risks among high-risk individuals, i.e. patients with two or more CHD risk factors as following: raised fasting blood glucose (BG) level, increased blood pressure (BP), increased triglycerides (TG), decreased HDL-Cholesterol (HDL-C), increased LDL-Cholesterol (LDL-C), smoking and central obesity (International Diabetes Federation, 2015). In addition, this study will provide the FFQ's concurrent validity in assessing the intake of energy and nutrients against the CDC-FFQ. Moreover, whether the FFQ could detect the known differences in energy intake between men and women will be established for its discriminant validity.
This is a Prospective, Open label, Non-randomized, Single-Arm, Multicenter Study to Evaluate the Procedural Safety and Efficacy of ELCA® in Treatment of Patients with Single or Multivessel Coronary Artery Disease (CAD). Up to 30 patients will be enrolled at up to 05 Indian study sites. Patients will be followed from enrollment through 30 days ± 7 days for the effectiveness and safety endpoints at the study centre.
