Urine Adiponectin Concentration in Prediction of Contrast Induced Nephropathy
Myocardial IschemiaThe present study is to determine the ability of urinary total adiponectin and its isoforms excretion in the prediction of contrast induced nephropathy (CIN) in the patients undergoing PCI.
Comparison of the HyperQ Versus Conventional Electrocardiogram (ECG) to Detect Ischemia
Coronary Artery DiseaseThe purpose of the investigation is to verify the efficiency of the HyperQ™ system in detecting exercise induced ischemia, with higher specificity and sensitivity than conventional ECG Stress testing. The study will be carried out by applying the HyperQ™ system during cycle ergometer stress testing in patients who are referred for angiography at the Department of Cardiology, Essen University Hospital, Essen, Germany. The HyperQ™ results will then be compared to the standard ECG stress test results using the angiography results as the gold standard. The study will be considered successful if analysis of the HyperQ provides a statistically significant improvement over the diagnostic accuracy of conventional ECG stress testing analysis.

Correlation Between the Severity of Coronary Artery Disease and Peripheral Arterial Stiffness in...
Premature Coronary Heart DiseasePremature coronary heart disease (CHD) refers to the onset of myocardial infarction in men < 55 years old, women < 65 years old. At present, researches on early-onset coronary heart disease mostly focus on its risk factors and clinical characteristics, but there is no relevant research on the relationship between early-onset myocardial infarction and atherosclerosis.
Correlation Between Quantitative Analysis of Coronary MRA and FFR
Coronary Artery DiseaseMagnetic Resonance Angiography1 moreThis study aims to evaluate whether quantitative analysis of coronary MR angiogram would improve the detection of functionally-significant coronary artery stenosis.
Relation Between Postprandial Lipogram and Coronary Artery Disease Severity
Postprandial DyslipidemiaCoronary artery disease (CAD) is usually used to refer to the pathological problem affecting the coronary arteries (usually atherosclerosis) that leads to Coronary Heart disease (CHD) which includes the diagnoses of angina pectoris, MI and silent myocardial ischemia. Despite the mortality for this condition has gradually declined over the last decades in western countries, it still causes about one-third of all deaths in people older than 35 years. Dyslipidemia is very important risk factors of atherosclerosis that is one of the causes leading to cardiovascular disease Despite management of dyslipidemia by controling fasting total plasma cholesterol and LDL cholesterol as these are the best biomarkers for prediction of cardiovascular diseases (CVD) risk. LDL elevation is absent in many patients with atherosclerosis and about 1/3 of cardiac events remains to be unpredicted using this method. Even more, in fasting normolipidemic subjects, increased CVD risk is associated with an exaggerated postprandial lipemic response. Postprandial dyslipidemia is defined as a rise in triglyceride-rich lipoproteins (TRLs), including chylomicron remnants (CMRs) and remnant lipoproteins (RLPs), after eating, has drawn an increasing interest recently because of its association with cardiovascular events. Chylomicron remnants (CMRs) have been shown to penetrate the artery wall and to be retained within the intima. Endothelial dysfunction is an initial process of atherogenesis and it contributes to the pathogenesis of CHD. Postprandial hyperlipidemia (postprandial hypertriglyceridemia) is involved in the production of proinflammatory cytokines, recruitment of neutrophils, and generation of oxidative stress, resulting in endothelial dysfunction
Coronary Atherosclerosis Disease Early Identification and Risk Stratification by Noninvasive Imaging...
Coronary Artery DiseaseThe investigator prospectively enroll 30,000 outpatients who were suspected of coronary artery disease (CAD) and underwent cardiac computed tomography angiography (CTA). The endpoint was major adverse cardiac events (MACE).The investigator aim to evaluate the prognostic value of CTA, risk factors and bio-markers for MACE.
the Change of CEM and the Prognosis of Coronary Artery Disease in Real Clinical Practice
Coronary Artery DiseaseThe purpose of this study is to investigate the change of total cholesterol content of erythrocyte membranes (CEM) in patients with coronary artery disease treated with secondary prevention drugs, and the correlation with the prognosis.
Relationship Between OCT Coronary Plaque Morphology and Clinical Outcome
Coronary Artery DiseaseThe multicenter observational CLIMA registry has been conceived to explore correlation between OCT morphology of atherosclerotic plaques located in the left anterior descending artery with mid and long term clinical outcome.
