Active clinical trials for "Coronary Disease"

The investigators aimed to identify the value of concordance between the diastolic hyperemia-free ratio (DFR) and fractional flow reserve (FFR) during pre-interventional and post-interventional period using a 0.014" COMET II Pressure Guidewire

Our study focuses on the question about primary cardiac rehabilitation (CR) patients with coronary heart disease are concerned about demonstrating the association between the patients' view of CR and social associated factors. In our study, all participants are invited to choose at least 1 question in 15 questions or provide their questions regarding their doubt about the CR after filling in their personal information. The selectable questions can be categorized into five titles: the content or purpose of CR, the method of CR, the advantage of CR, the adverse effect of CR, and the expenditure of CR.

Multidisciplinary team-approach in order to offer personalized treatments represents the emerging mainstream in cardiovascular medicine. "Hybrid operative rooms" allow to offer selected heart-disease patients truly "tailored" operations. This study wants to evaluate the effectiveness and safety of Hybrid Procedures in cardiac patients in three subgroups of patients: Hybrid coronary revascularization strategy (coronary by-pass + PCI); Hybrid valve and coronary disease correction (combination of surgical valve replacement and PCI); Hybrid coronary and carotid artery disease treatment (combination of coronary by-pass and carotid stenting). The investigators hypothesize that morbidity might be reduced by 50% in hybrid procedures group as compared with predicted Society of Thoracic Surgery (STS) score.

This study sought to assess the diagnostic and prognostic values of metabolomics in coronary artery disease(CAD).

Patients with Chronic Coronary Syndrome (CCS) undergoing with elective percutaneous coronary intervention (PCI) are treated with dual antiplatelet therapy (DAPT), consisting of aspirin combined with clopidogrel for 6 months. The aim of DAPT is to prevent recurrent thrombotic events, i.e. death, stent thrombosis and/ or myocardial infarction (MI). However, the trade-off of thrombotic prevention by DAPT is an increased risk of bleeding. Multiple strategies to reduce bleeding risk and optimize outcomes have been proposed. On one hand the bleeding risk can be reduced by shortening the duration of DAPT and omitting aspirin. This has been proven effective in patients with acute coronary syndromes (ACS) compared to standard DAPT, without a significant difference in thrombotic events. On the other hand, personalized medicine by means of genotyping to ensure that a patient is treated with an, for them, effective drug, can be a strategy to optimize patients outcomes. In CCS patients the preferred P2Y12-inhibitor is clopidogrel. However, clopidogrel must first be activated by the CYP2C19 enzyme in the liver. Only then can clopidogrel inhibit the P2Y12-receptor and prevent platelet activation. Almost thirty percent of patients has a genetic variation of the gene encoding this CYP2C19 enzyme. In these patients, clopidogrel is not or hardly activated, putting them at a higher risk of thrombotic events than patients who do not have this gene variation. By determining the CYP2C19 genotype, it is possible to estimate whether clopidogrel will be effective or not. In this trial the investigators evaluate the pharmacodynamic effects of genotype guided P2Y12-inhibitor monotherapy in patients with CCS undergoing PCI. In the intervention arm the CYP2C19 genotype will be assessed using a point-of-care test device on the cardiology ward, which can be performed by (research) nurses. Patients with a CYP2C19 loss-of-function (LOF) allel will be treated with monotherapy ticagrelor or prasugrel. Patients who are non-carrier of a LOF allel will receive clopidogrel. The control arm will be treated with the current standard-of-care, which is DAPT, consisting of aspirin combined with clopidogrel for 6 months. The main goals is to assess the antithrombotic effects of individualized P2Y12 monotherapy strategy versus clopidogrel plus aspirin in elective PCI patients.

A considerable proportion of patients with clinically suspected coronary artery disease (CAD) do not have angiographic signs of luminal narrowing caused by coronary atherosclerosis. In patients with suspected CAD, we will assess the ability of cardiovascular biomarkers to identify patients with (a) angiographically normal epicardial coronary vessels (b) absence of significant epicardial coronary stenosis, as assessed by coronary computed tomography angiography (CCTA). Patients will be stratified according to the presence or absence of dynamic changes of high sensitivity cardiac troponin T levels above the 99th percentile.

Coronary artery disease (CAD) is the leading cause of morbidity and mortality in developed countries. In addition, many patients suffer from valvular and aortic disease. Although various tools are available to identify patients with cardiovascular (CV) disease at risk for major adverse cardiac events (MACE), the identification of these patients remains a clinical challenge. One promising avenue is the use of different serum biomarkers involved in atherothrombosis which could provide an easy and cost-effective step in risk stratification.

Nicorandil is potentially effective to prevent cardiovascular events in patients with coronary artery disease (CAD) receiving hemodialysis. The purpose of this study is to prospectively investigate whether nicorandil is effective in reducing the incidence of cardiovascular events in patients with CAD on hemodialysis.

The purpose of this study is to evaluate the relative effectiveness and safety of Onyx stent compared to other (drug eluting stents) DES.

This study evaluates effectiveness and safety of DESyne X2 in Routine Clinical Practice.
