Functional Diagnostic Accuracy of Quantitative Flow Ratio in Tandem Lesions and Virtual Stenting...

Coronary Artery DiseaseCardiovascular Diseases5 more

Quantitative Flow Ratio (QFR) is a novel method for evaluating the functional significance of coronary stenosis. Virtual stent implantation technique combined with QFR was recently developed to predict the functional significance of coronary stenosis as if the stenosis was revascularized. The purpose of this study is to evaluate the diagnostic accuracy of QFR in in tandem lesions with fractional flow reserve (FFR) as the reference standard. The secondary purpose is to evaluate the diagnostic accuracy of QFR-based virtual stent technique in predicting the FFR values after revascularizing the culprit lesion.

Retrospective Cohort Study on Post Analysis on the Link Between the Clinical Heart Rate and Outcomes...

Coronary Heart Disease

The trial is a single centre, retrospective cohort, non-interventional study to be conducted in the department of cardiology, Chinese PLA General Hospital, Beijing, China. To evaluate the link between mean perioperative clinical heart rate and short-term composite outcomes during PCI among local CHD patients.

Pro-calcitonin Marker as Indicator of Ischemia in Patients With Complicated Coronary Intervention....

Coronary Disease

The aim of this study is to determine on preliminary basis weather an elevated pro-calcitonin level can be used to assess ischemia as a result of coronary artery complications during percutaneous coronary intervention (PCI).

New Vectorcardiogram Analysis a Good Predictor of Coronary Disease in Patients With Normal Rest...

Cardiovascular Disease

The aim of this study is to determine whether a new vectorcardiogram (VCG) analysis will facilitate the detection of significant coronary disease (CAD) in patients with normal rest 12-leads ECG (NE).

Aspirin Response in High Risk Patients With Coronary Artery Disease

Coronary Artery DiseaseMyocardial Infarction3 more

Previous studies indicate that patients with cardiovascular disease have a variable response to aspirin. Despite treatment with aspirin a large number of patients suffer a myocardial infarction. This has given rise to the phenomenon "aspirin low-responsiveness". Laboratory aspirin low-responsiveness can be defined as the failure of aspirin to inhibit platelet production of thromboxane A2 or inhibit thromboxane-dependent platelet aggregation. Whether a low platelet response to aspirin results in an increased risk of future thrombotic events is of great clinical significance, but is still unknown. The investigators hypothesize that patients with a reduced response to aspirin, determined by platelet aggregation using the apparatus Verify Now Aspirin and Multiplate, have a higher risk of thrombosis. The purpose of this study is to investigate whether a higher incidence of cardiovascular events is found in patients with coronary artery disease (CAD) having a reduced biochemical response to aspirin compared with CAD patients having a normal biochemical response to aspirin. In addition to CAD, all patients have at least one of the following risc factors: previous myocardial infarction, type 2 diabetes mellitus and/or renal insufficiency.

Clinical Impact of Cytokine in Cardiac Surgery

Coronary Disease

Cardiac surgery leeds to a systematic inflammatory response induced by the surgical trauma and the use of the cardiopulmonary bypass (CPB). Activation of inflammatory cascades can cause a systemic inflammatory response syndrome (SIRS) which is associated with increased morbidity and mortality. Therefore, strategies to reduce the inflammatory response have a potential benefit for cardiac surgery patients. The clinical benefit of reducing proinflammatory cytokines such as IL-6, Il-8 and TNF-a with the use of a cytokine adsorbing circuit (Cytosorb) during CBP remains unclear. Therefore, the investigators conduct this prospective, observational pilot study to determine the clinical impact of the use of a cytokine adsorbing circuit during CBP.

Prevalence of Coronary Artery Disease in the Siblings of Premature Coronary Heart Disease

Coronary Heart Disease

The aim of this prospective study is to investigate the prevalence of coronary artery disease using computed tomography with family history of premature coronary heart disease

Genetic Predisposition of Coronary Artery Disease -- The COROGENE-Study

Coronary DiseaseInflammation

The aim of this study is to identify genetic loci,or gene variations contributing to inflammation and to the development of CHD. We will compare coronary angiogram results to genetic findings within coronary artery disease patients and in patients with normal coronaries.

Coronary Artery Geometry and the Severity of Coronary Atherosclerosis

Coronary Artery DiseaseAtherosclerosis2 more

The purpose of this study is to investigate the potential association of coronary artery geometry, based on coronary CT angiography (CCTA), with the complexity and the severity of coronary atherosclerosis.

Unknown status8 enrollment criteria

Evaluation of Inflammatory Markers and Periodontal Viruses on Periodontitis Patients With CAD

PeriodontitisCoronary Artery Disease

To assess and compare the demographic variables, periodontal parameters, cardiac parameters and the expression of periodontal viruses (CMV, HSV and EBV) and inflammatory biomarkers(PTX-3, TLR-2 & TLR-4) in periodontally healthy and generalized periodontitis patients with and without coronary artery disease(CAD).
