Active clinical trials for "Coronary Disease"

Evaluate the prevalence of familial hypercholesterolemia (FH) in patients with documented coronary artery disease (CAD) event [acute myocardial infarction (AMI), acute coronary syndrome (ACS), coronary artery bypass graft (CABG) or percutaneous coronary intervention (PCI)] followed by 100 cardiological centers representative of the whole Italian territory

Coronary heart disease (CHD) is the leading cause of death worldwide. The disease is characterized by a high mortality rate (about 40%) and a course continuously altered by lifestyle, gene polymorphisms and therapeutic treatment. Fasting concentration of blood lipids and lipoproteins only partially express the complex relation between dyslipidemia and CHD. Following the indication stated nearly 40 years ago by Zilversmit, there is now accumulating evidence that postprandial lipemia plays an important role in the atherogenic process [ref Kolovou], particularly that most hours of the day are spent in the postprandial state. Furthermore, the increases in blood glucose and triglycerides (TGs) following meals stimulate oxidative stress, impair endothelial function, and rises the inflammatory factors that lead to atherosclerosis. Previous studies reported on postprandial lipemia in subjects with obesity, metabolic syndrome, diabetes mellitus, elderly, patients with CHD and others. However, currently the estimation of cardiovascular disease risk is based on fasting blood values of triglycerides (TGs) and inflammatory markers. The effect of postprandial atherogenic factors on the initiation and progression of atherosclerosis is actually not known.The Hellenic Postprandial Lipemia Study (HPLS) was designed to study the consequences of postprandial lipemia in CRP as inflammatory marker in high-risk adults. Furthermore, the HPLS study will investigate whether hypolipidemic, hypoglycemic or antihypertensive medication may lessen the exaggerated postprandial lipemia as well as the rest abnormal postprandial metabolism. Finally, the HPLS study is intending to evaluate the influence of gene polymorphisms involved in lipid and glucose metabolism on postprandial lipemia and cardiovascular outcomes.

The objective of the DeQCAD study is to measure the quality of the decision-making process for patients with coronary artery disease (CAD) and Acute Coronary Syndrome (ACS) who are making treatment decisions. In particular, this study is seeking to answer: a) How informed are patients about their treatment choices, b) are patients participating in the decision-making process as much as they would like to, and c) do the treatment decisions made match patients' preferences?

The purpose of this study is to investigate the variation in blood glucose levels, hemodynamic effects and patient anxiety score during tooth extraction in type 2 diabetes mellitus with coronary disease patient under local anesthesia with lidocaine 2% with and without epinephrine.

Background About 2/3 patients of coronary heart disease (CHD) are complicated with disorder of carbohydrate metabolism which results in hyperglycemia and subsequent abnormality of coagulation system and inflammation. These patients have serious coronary artery pathology, multiple complications and poor prognosis. Platelets and lymphocytes play important roles in the occurrence and progression of atherosclerosis. The platelet/lymphocyte rate (PLR) is one simple hematological index. Previous studies confirmed that PLR could predict the long-term mortality of non-ST elevated myocardial infarction (NSTEMI). If simple hematological index could predict the prognosis of such kind of patients, it will provide new thought for early diagnosis and treatment in future. Therefore, the present study try to investigate if PLR could predict the poor prognosis of CHD patients complicated with impaired glucose tolerance (IGT) through calculating PLR. Methods/design The present study is performed with strategy of an observational and prospective single-centre cohort. These patients are recruited from August 2013 to August 2014, according to the inclusion criteria of CHD complicated with IGT. CHD is confirmed with coronary angiography while IGT is determined according to the WHO criteria (1999). Routine blood test and serum glucose data of patients are acquired before hospitalization and surgery. According to the median of PLR after admission, the patients are divided into 3 groups. The patients are followed up for half, 1 and 3 years, respectively. The major clinical endpoint is mortality. The minor clinical endpoint indices are the correlations of PLR with MACE (including mortality, recurrent rate of infarction and reperfusion rate of target vessels), recurrent infarction, re-perfusion rate of target vessel, intra-stand thrombogenesis, stroke and acute onset of heart failure. The correlations are analyzed with receiver operating characteristics (ROC) survival curve and Kaplan-Meier survival analysis to find optimal prognosis index. Summary Through regression analysis of long-term follow-up of patients, it is expected to find optimal predicting index of prognosis. While judging whether PLR is effective, other possible factors for new predictor are sought in order to provide help for future study.

In acute coronary artery disease, pre-clinical studies have indicated that, during a continuous infusion of intravenous perfluorocarbon containing microbubbles, the ultrasonic power delivered from a diagnostic ultrasound transducer is capable of restoring microcirculatory flow and improving epicardial recanalization rates obtained by conventional therapy, a process known by Sonothrombolysis. The investigators proposed to examine the feasibility, safety and efficacy of such an ultrasound guided approach in 100 patients with ST segment elevation myocardial infarction (STEMI).

Antiplatelet therapy is the cornerstone for the prevention of atherothrombosis in patients with coronary artery disease (CAD). However, the efficacy and safety of antiplatelet therapy are varied due to ethnic and/or individual variability. The aim of the OPT-CAD study was to demonstrate contemporary status and outcomes of antiplatelet therapy in Chinese CAD patients, and to explore predictors of ischemic or bleeding events in such cohort.Patients above 18 years old who were diagnosed as CAD and received antiplatelet therapy were prospectively enrolled in this national wide, non-intervention registry. All medications and laboratory tests were physician discretion.

Coronary artery disease (CAD) is one of the leading causes of morbidity and mortality worldwide. Life threatening manifestations such as acute myocardial infarction (AMI) and sudden cardiac death are the most important causes of death in many countries. Cardiac troponin is a biomarker with a high specificity for cardiac necrosis and is recommended for diagnosis of acute myocardial infarction by the Universal definition of myocardial infarction. Since a new generation of high-sensitivity cardiac troponin assays has become commercially available a few years ago, myocardial infarction can be detected earlier and even small AMIs, that were classified as unstable angina pectoris (UAP) with the less sensitive assays, are detectable now. On the other side, more patients with acute or chronic myocardial damage not due to AMI are identified now. Thereby, the reason for elevated troponin levels should be sought actively, because high troponin levels were associated with adverse outcome - independent of the underlying pathomechanism. The reasons for troponin elevations in patients with stable CAD are not clear yet. Associations with extensive atherosclerosis, carotid lesions and complex coronary plaques in coronary CT scans were reported. Therefore, patients with elevated troponin levels represent a risk population and might profit from intensified secondary prevention. In this context, ticagrelor might be part of a prevention strategy as currently tested in the PEGASUS trial. We plan to conduct a single-centre pilot study in a cohort with clinically stable patients of our outpatient clinic, because data regarding prevalence, causes and prognosis of elevated troponin values in unselected cohorts is sparse. Therefore, all patients (n=910) that presented to our outpatient clinic 12 months after introduction of the high-sensitivity troponin T assay (june 2009) and were free of complaints or presented with UAP are being enrolled. All patients are characterized by demographic, laboratory and clinical characteristics (including medication) and all available imaging data (exercise-ecg, echocardiography, stress-echocardiography, computed tomography, cardiac MRI and coronary angiography) in order to compare baseline characteristics of troponin positive and troponin negative patients. In addition, the Framingham- and PROCAM-Score representing established calculators of long-term risk prediction are calculated. Prognostic endpoints are defined as severe cardiovascular events and progress of the initially diagnosed disease. Those endpoints are associated with the initial hs-cTnT value and serial changes.
