Active clinical trials for "Coronary Artery Disease"

The objective of the study is to evaluate the safety and efficacy of XIENCE Xpedition Everolimus-Eluting 2.25mm Stent in real world practice in Japanese hospitals.

Background: The cardiomyocytes apoptosis induced by ischemia-reperfusion(I/R) is one of the most important factors in the myocardial I/R injury(MIRI) undergoing cardiac valve replacement with cardiopulmonary bypass(CVRCPB),and Ischemic postconditioning (I-postC) can inhibit apoptosis of myocardial cells. Consequently, this study investigated the key genes and apoptosis signaling pathways of myocardium in patients undergoing CVRCPB. Methods: A total of 36 New York Heart Association class II or III patients with rheumatic heart disease (RHD) of both sexes, aged 21-59 years, who were scheduled for first cardiac valve replacement with CPB in the investigators' hospital from February 2014 to May 2015, were randomly divided into the following three groups (n=12 each): negative control group (NEG group); I/R group (POS group); and I-postC group (Treat group). In the Treat group, the procedure involved 5 min before opening the ascending aorta, aortic unclamping for 30 s, and cross-clamping for 30 s for three cycles, after which the ascending aorta was completely opened. The NEG and Treat groups were not treated. Thirty-six patients were assessed for arrhythmia and recovery of myocardial contractile function after reperfusion by electrocardiograms and degree of dependence on vasoactive drugs. The myocardial tissues of the right atrial appendage were obtained at 3 min before CPB was established in the NEG group, and at 45 min after opening the aorta in the POS and Treat groups. In all three groups, the myocardial tissues of the right atrial appendage were obtained and preserved at -80°C for further experiments. The right atrial appendage of three patients randomly selected in each group was fixed with RNA later (Qiagen, Hilden, Germany) in a centrifuge tube overnight at 4°C, and then preserved at -20°C for RNA extraction. Human 12×135K Gene Array profiling of mRNA expressions was undertaken in human cardiac muscle cells. Differentially expressed mRNAs verified by quantitative real-time RT-PCR were subjected to pathway analysis. The mRNA expressions of AIF, APAF1, CYCS, Bax, caspase-3, caspase-9, caspase-6, caspase-7, BCL2, BAG1, and PI3K were assessed by real-time RT-PCR and western blot analysis. The levels of myocardial apoptosis induced by I/R were investigated by TUNEL assays. The changes in MIRI induced by myocardial apoptosis were investigated by pathologic examination of the myocardium.

The Holding Area LINQ Trial is a clinical trial designed to compare the benefits in conducting impant procedures in the holding area of a hospital operating room vs cardiac catheterization/electrophysiology laboratory.

The purpose of the study was to analyze negative affectivity (NA) and social inhibition (SI) inquired by DS14 score in type D personality (distressed personality) to the relation of autonomic regulation of heart function (HRV) and immune response (T lymphocyte) among obese patients within coronary heart disease group (CHD). As stress is the key psychological activator of the hypothalamic-pituitary-adrenal axis (HPA axis) and therefore an important risk factor for diminished immune competency and prevalence of chronic conditions such as obesity, investigators chose exercise as the stress release intervention, especially as chronic stress may have a role in obesity, related to initiation or exacerbation of the condition. Abnormal regulation of the hypothalamic-pituitary-adrenal axis is additionally associated with chronic inflammatory conditions. Proinflammatory T-lymphocytes are present in visceral adipose tissue and may contribute to local inflammatory cell activation before the appearance of macrophages, suggesting that these cells could play an important role in the initiation and perpetuation of adipose tissue inflammation.

The purpose of this trial is to investigate the relationship between DNA methylation and hydroxymethylation and the expression of DNMTs, TET family gene and the degree of coronary heart disease.

This trial will compare the procedural success rate between right and left radial approach in patients undergoing coronary angiography and coronary intervention.

One-center, observational, non-interventional, prospective study of the efficacy of azilsartan medoxomil in patients with arterial hypertension associated with stable ischemic heart disease and type 2 diabetes mellitus.

It is well established that clopidogrel-induced antiplatelet effects is suboptimal in many patients who are thus exposed to an increased risk of adverse cardiovascular events. Studies have shown that genotypes of the cytochrome P450 (CYP) 2C19 enzyme, which is a key determinant of clopidogrel metabolism, contribute to these findings. Prasugrel and ticagrelor are alternative agents whose effectiveness is not dependent on CYP2C19 genotype. A boxed warning on the Food and Drug Administration (FDA)-approved clopidogrel labeling warns of reduced effectiveness in patients with the LOF genotype and recommends alternative therapies in these patients. The availability of an assay recently approved by the FDA, SpartanRX, which provides results within one-hour facilitates performing genetic testing as a clinical test in real-world practice. We therefore propose to 1) examine the feasibility of implementing CYP2C19 genotyping using SpartanRX as standard of care for patients undergoing cardiac catheterization at UF Health Jacksonville providing the opportunity for clinicians to embrace genotype-guided antiplatelet therapy in those who proceed to PCI and 2) determine if CYP2C19 genotype-guided antiplatelet therapy reduces the risk for major adverse cardiovascular outcomes after PCI.

This is an analysis conducted in the Nurses Health Study and the Health Professional Follow-Up Study, both prospective cohort studies, where the investigators systematically investigated the association between carbohydrate quality using a variety of metrics in relation to coronary heart disease. This was a secondary data analysis of previously collected data in both cohorts.

The purpose of the study: to increase the efficiency of diagnosis, treatment and prediction of the course of coronary heart disease in patients with adenocarcinoma of the prostate gland, depending on the hormonal status by determining the cardiovascular risk factors, factors of angiogenesis, structural and functional state of the heart, coronary vessels, kidney damage and their pharmacological correction.
