Active clinical trials for "Coronary Artery Disease"

A prospective analytic study to evaluate the incidence, clinical and laboratory characteristics, extent of coronary artery disease and short-term outcome of newly diagnosed diabetes and pre-diabetes in patients with first-time diagnosed coronary artery disease treated in Saud Al Babtain Cardiac Center.

Although epigenetics has been identified as one of the most relevant pathophysiological components in the development of cardiovascular diseases, there is still considerable difficulty in finding markers of epigenetic damage useful in clinical practice. Moreover, these markers could be useful to predict the onset and severity of disease as well as to stratify stratification the prognostic risk during the follow-up. The aim of this project will be to evaluate the genome wide DNA methylation status in circulating CD4+ T cells and CD8+ T cells in patients with acute coronary syndromes (ACS), atrial fibrillation (AF) and with ACS in the presence of AF.

The purpose of the FUSION study is to validate the diagnostic performance of Virtual Flow Reserve (VFR) by comparing it against a reference standard, fractional flow reserve (FFR).

The research question was to investigate whether non-surgical periodontal therapy could reduce cardiovascular risk markers in Coronary heart disease (CHD) patients.

Background Revascularization of complex coronary artery disease, including multivessel coronary artery disease, left main stenosis, bifurcation stenosis and chronic total occlusions (CTO) can be performed by Percutaneous Coronary Intervention (PCI) or Coronary Artery Bypass Graft (CABG), according to current guidelines.[1] In order to decide whether to revascularize by either CABG or PCI, patient characteristics, the presence of comorbidities, including diabetes, and coronary lesion complexity (e.g. SYNTAX) should be taken into consideration. Because of the ageing population with a higher incidence of comorbidities and higher surgical risk scores, high-risk PCI in complex coronary disease with high risk for periprocedural cardiogenic shock is increasingly performed.[2, 3] Mechanical Circulatory Support (MCS) devices for elective high-risk PCI can provide hemodynamic support, preventing hemodynamic failure during PCI. Several studies are performed using Intra-Aortic Balloon Pump (IABP) and co-axial left cardiac support device (Impella device (Abiomed, Danvers, USA)), showing no clear benefits in patients with high-risk PCI.[4-6] Veno-Arterial Extracorporeal Membrane Oxygenation (VA-ECMO) is a recent addition to mechanical support options, providing more extensive hemodynamic support in patients with potential or ongoing failure of circulation. This concept is already demonstrated in the setting of Extracorporeal Cardiopulmonary Resuscitation (ECPR).[7, 8] ECMO has the additional benefits of right ventricular unloading and blood oxygenation as opposed to IABP and Impella.[9] Our experience with fully percutaneous VA-ECMO in cardiogenic shock and for ECPR combined with the experience for Transcatheter Aortic Valve Replacement (TAVR) with local anaesthesia and mild sedation resulted in the selection of VA-ECMO as our preferred method in high risk PCI. Studies investigating the use of VA-ECMO support during high-risk PCI are however limited.[10-13] Objective The aim of this study is to provide additional data concerning the short-term outcomes of elective high-risk PCI with VA-ECMO in a single PCI centre. Methods Design We will perform a single-centre, retrospective registry, using data collected from medical records of included patients. Inclusion criteria Patients older than 18 years, who underwent high-risk PCI with VA-ECMO support. The use of mechanical circulatory support (MCS) is indicated by HeartTeam based on patient and lesion characteristics described in the expert consensus on the use of MCS Devices for high-risk PCI. [14] Exclusion criteria • Non-elective PCI with VA-ECMO support, primarily applied for cardiogenic shock or ECPR. Study Procedures All patients older than 18 years who underwent high-risk PCI with VA-ECMO support will be included in the registry. Baseline patient and angiographic characteristics, ECMO characteristics and short-term outcomes, described in the paragraph 'Study Endpoints and Definitions' will be collected from medical records. The Dutch Act on Medical Research involving Human Subjects (WMO) does not apply to this study, because of the retrospective design of the study using only medical records and consequently patients are not subjected to additional procedures. Therefore, no written informed consent will be obtained from patients or legal representatives as well. Data Collection All data will be collected in a cloud-based electronic case report form (eCRF, Castor Electronic Data Capture), which will be developed and managed by investigators in the Radboudumc. Only members of the study team will have access to the patient eCRFs and will be allowed to enter data in the system. The study team exists of the investigators mentioned earlier. The study team will collect the data from medical records and enter the data in Castor. All patient data will be encoded. Only the investigators involved will have access to the patient identification key. Study Endpoints and Definitions Successful revascularization is defined as final residual stenosis <50% with a TIMI flow grade 3, achieved in at least one of the target vessels. Procedural success is defined as angiographic success without the occurrence of peri-procedural MACE, including death and myocardial infarction (MI). Additionally, MACE will be assessed during hospital stay and within 60-days follow-up after discharge and defined as a composite of death, MI, Target Vessel Revascularization (TVR) by PCI or CABG and clinical bleeding, assessed by the Bleeding Academic Research Consortium (BARC) scale. Bleeding complications of type 2 and higher are included.

Title: Combined Optical Coherence Tomography Morphologic and Fractional Flow Reserve Hemodynamic Assessment of Non-Culprit Lesions to Better Predict Adverse Event Outcomes in Diabetes Mellitus Patients COMBINE (OCT-FFR) Prospective Register To study the natural evolution of patients with at least one intermediate angiographic but non-hemodynamic significant stenotic lesion, in two subgroups of patients, with TCFA vs. no TCFA as detected by OCT imaging and to compare these two groups of patients with each other as well as to a subset of patients with FFR-positive and PCI-treated intermediate lesions on future MACE.

Coronary artery disease (CAD) is associated with high mortality worldwide. Narrowing of the coronary arteries can cause an acute myocardial infarction. Patient with cardiac ischemia are often treated with percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). Following hospitalisation, the patients are offered to attend a classical rehabilitation program with moderate exercise intensity. Current exercise program for cardiac rehabilitation has proven to reduce cardiovascular risk factors 1. Is it possible to improve the exercise capacity and risk profile even more if the exercise program includes more vigorous training? The program starts one week after the cardiac incident (AMI, PCI or CABG) and takes 12 weeks to complete. Patients with heart failure and valvular disease are excluded. First ventilatory threshold (VT1) and second ventilatory threshold (VT2) are determined during cycloerometry. VT2 reflects aerobic-anaerobic transition and therefore the aerobic functional capacity2. Exercise load reached at VT2 is used to determine the training load during rehabilitation. The research goal is to investigate the influence of training intensity on the exercise capacity and risk profile of CAD patients.

This study aimed to explore the associations between constitutions of traditional Chinese medicine (TCM) and common disease (CD). A large-scale, community-based, cross-sectional study was performed to investigate the associations. A total of 3748 participants were available for analysis in this study. The assessment of constitution of TCM was based on recommendations of Association Chinese Medicine in China. In this study, the diagnosis of CD was based on self-reported medical history. The associations were analyzed using univariate and multivariable logistic regression (MLR).

There is growing evidence that central blood pressure is a better predictor of hypertensive end-organ damage and cardiovascular outcome than routine brachial readings. The investigators aimed to evaluate the accuracy of a novel device for the non-invasive determination of central blood pressure based on automated oscillometric radial pulse wave analysis.

The aim of the study is to compare different devices available to measure fractional flow reserve (FFR) in coronary arteries.
