Active clinical trials for "Myocardial Ischemia"

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: Cardiac rehabilitation is indicated for ischemic heart disease patients; the program content of which is well described in both European and American guidelines. In contrast, literature on cardiac rehabilitation program content and efficacy in the Asian population is sparse. Methods: BeSingCardioRehab will be an intercontinental, retrospective cohort study conducted in two cardiac rehabilitation referral centers in Belgium and Singapore. The first aim is to compare the impact of phase II center-based cardiac rehabilitation on Major Adverse Cardiac Events for ischemic heart disease patients between Europe (i.e. Belgian) and Asia (i.e. Singaporean) in the long-term. The second objective is to compare the efficacy of phase II cardiac rehabilitation on short-term morbidity (assessed with the validated SMART Risk Score) between index European and Asian ischemic heart disease patients. The level of compliance of the Belgian and Singaporean cardiac rehabilitation programs to European guidelines standards will also be evaluated. Hypotheses BeSingCardiorehab will be one of the first studies assessing cardiac rehabilitation in Asia. Based on the BeSingCardioRehab study results, phase II center-based cardiac rehabilitation programs, can/will be adapted in order to improve program content and outcomes.

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

The purpose of this study is to determine whether Rosuvastatin 10mg/d or 20mg/d for 36 weeks can regress critical coronary atherosclerosis as determined by IVUS imaging in Chinese Acute Coronary Syndrome (ACS) patients.

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.

CAROLE seeks to evaluate the relationship between chest Radiation Therapy and coronary artery disease. The purpose of CAROLE is to check the heart health of women who received breast cancer treatments in the past and protect them from future heart disease.

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.

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.

The aim of this study is measurement of expression and activity of RBC eNOS in different clinical cohorts of patients with coronary artery disease and acute coronary syndrome and to investigate the importance of the NO-stimulated reaction cascade in terms of sGC and PKG.
