NCT ID: NCT03315234 Recruiting - Clinical trials for Coronary Artery Disease

Correlation of Genetic Polymorphisms and Clinical Parameters With the Complexity of Coronary Artery Disease

Start date: September 1, 2016
Phase: N/A
Study type: Observational [Patient Registry]

The purpose of the research project is to investigate the potential association of 6 genetic polymorphisms with the complexity and the severity of coronary artery disease (SYNTAX score). The aim of the study is to combine genetic, clinical and laboratory data in order to create a prognostic tool that will enable an individualized therapeutic patient approach.

NCT ID: NCT03313752 Recruiting - Clinical trials for Type2 Diabetes Mellitus

Effects of SGLT2 Inhibition on Myocardial Insulin Sensitivity

Start date: December 1, 2017
Phase: Phase 3
Study type: Interventional

A Phase III, single-centre, randomized, 2-arm, parallel-group, double blind, placebo-controlled study, consisting of a screening phase (Days -14 to -1), a 4-week double-blind, placebo-controlled treatment phase and a 4-week follow-up phase. Subjects: Type 2 diabetic patients with coronary artery disease (CAD) not requiring revascularization, with sub-optimal glycemic control (HbA1c 7.5-8.5%) on their current anti-hyperglycemic regimen Subjects will be randomized in a 1:1 ratio to dapagliflozin or placebo. Subjects will undergo screening assessment in the 14-day period preceding administration of the first dose of study drug on Day 1. Primary Objective The primary objective is to assess the effect of dapagliflozin on myocardial insulin sensitivity Secondary Objective The secondary objective is to assess global heart function, and metabolic systemic effects of dapagliflozin, and glycemic control. The study aims to enroll patients with type 2 diabetes with poor glycemic control, and with coronary artery disease not requiring revascularization, who have already undergone, under routine cardiological assessment, a positron emission tomography (PET) 13NH3 scan in order to assess the cardiovascular function. Thus, the study aims to assess whether the improvement in cardiac metabolism obtained with dapagliflozin is greater than that obtained with normal clinical practice (according to Standards of Care).

NCT ID: NCT03308539 Recruiting - Clinical trials for Myocardial Infarction

Prediction of Coronary Artery Disease Severity by Epicardial Adipose Tissue Thickness

Start date: November 1, 2017
Phase: N/A
Study type: Observational

is to test the hypotheses that epicardial adipose tissue can be a marker of severity of coronary artery disease in myocardial infarction patients

NCT ID: NCT03304496 Recruiting - Clinical trials for Coronary Artery Disease

Subcutaneous Nitroglycerin to Facilitate Trans-radial Access.

Start date: March 30, 2017
Phase: Phase 4
Study type: Interventional

Femoral artery approach to perform coronary procedures is considered the standard technique for vascular access due to optimal catheter control, lower thromboembolic complications and immediate access due to the large diameter of the artery. Trans-radial approach has been shown to reduce major bleeding complications, vascular complications related to the site of puncture, including death from all causes, and to prevent post-procedure limb rest, greater comfort for patients, immediate ambulation, early discharge and reduction of costs. Previous studies have shown that intravenous, topical and intraarterial use of nitroglycerin produces vasodilation of the radial artery. Extravascular (subcutaneous) administration of nitroglycerin is extremely effective in restoring the radial pulse, and allows adequate cannulation.

NCT ID: NCT03292367 Recruiting - Clinical trials for Coronary Artery Disease

The Procedural Success and Complication Rate of the Left Distal Transradial Approach

Start date: October 11, 2017
Phase: N/A
Study type: Observational

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.

NCT ID: NCT03292354 Recruiting - Cardiac Disease Clinical Trials

Personalization of CM Injection Protocols in Coronary Computed Tomographic Angiography

Start date: April 11, 2017
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT03280433 Recruiting - Clinical trials for Coronary Artery Disease

Influence of EPICardial Adipose Tissue in HEART Diseases: EPICHEART Study

Start date: September 1, 2014
Phase: N/A
Study type: Observational

This translational study was designed to explore the association of the quantity and quality of epicardial adipose tissue (EAT) with coronary artery disease (CAD), left atrial remodeling and postoperative atrial fibrillation in a high cardiovascular disease-risk population. The investigators expect to identify new biochemical factors and biomarkers in the crosstalk between the epicardial adipocytes, coronary plaques and atrial cardiomyocytes that are involved in the pathogenesis of atherosclerosis and atrial fibrillation, respectively.

Communicational Program "Trust" to Improve Adherence to Medications

Start date: March 1, 2017
Phase: N/A
