Filter by:The RITMO (Registro Italiano sul trattamento del Tronco coMune non protettO) observational study will appraise the prevalence, management strategy, and prognosis of unprotected left main coronary artery disease in Italy.
The goal is to determine if prehydration based on LEVDP is superior to a standard hydratation with NaCl 0.9% or NaHCO3 for the prevention of contrast nephropathy related to a diagnostic coronary angiogram or to PCI.
The purpose of the study is to compare two surgical strategies for coronary artery bypass grafting with respect to the occurrence of cerebral infarctions made visible by magnetic resonance imaging
Background—Despite the pivotal pathogenic role of platelets in atherothrombosis has been widely recognized, there is a striking lack of consensus regarding how to measure platelet function and how to monitor the effects of various antiplatelet drugs. In view of the fact that recurrent ischemic events occurred in 8.5% to 8.8% of patients treated with dual antiplatelet drugs and there is significant inter-individual variability in platelet reactivity, we believe that the importance of platelet function assessment and its clinical implication should not be overlooked.
The purpose of this prospective, non-randomized, single-arm feasibility study is to evaluate safety and feasibility of the iCoapsys System in patients with functional mitral valve insufficiency caused by annular dilation and/or papillary muscle displacement.
Atherosclerotic cardiovascular disease is the major cause of morbidity and mortality in Western societies. It is a complex genetic disorder with many genes involved and significant gene-environment interactions. The aim of the study is to identify novel genetic- and biological-markers of atherosclerosis. Atherosclerosis is assessed in the coronary arteries using coronary angiography as well as in the carotid artery (intima-media-thickness) and peripheral vessels (ankle brachial index). Association analysis of genetic and metabolic markers with atherosclerotic burden will be performed to identify novel factors of disposition to atherosclerotic vascular disease.
The purpose of this study is to determine whether the use of drug eluting stents is associated with higher rates of death, myocardial infarction, and major bleeding. In addition, the overall economic costs of implanting drug eluting stents compared to bare metal stents will be assessed.
The purpose of this study is to compare the rates of vascular related complications in patients undergoing percutaneous coronary intervention assigned to one of two arms: 1) bivalirudin + provisional Gp IIB/IIIA use versus 2) heparin + Gp IIB/IIIA (eptifibatide (Integrilin®)) use.
Patients with coronary artery disease are characterized by an increased cardiovascular risk and they often have low blood high density lipoprotein (HDL)-cholesterol levels or HDL-cholesterol with modified vasculoprotective properties. The purpose of the present study is to characterize the quality of HDL-cholesterol in patients with coronary artery disease and normal blood HDL-cholesterol levels and to examine the effect of exercise training on the vasculoprotective effects of HDL-cholesterol in these patients. Additionally, the researchers aim to investigate the endothelial function, oxidative stress and the regenerative capacity of the endothelial progenitor cells in patients with coronary artery disease and the changes dependent on physical activity of patients.
The main objective of this study is to determine the usefulness of the HyperQ™ System in improving the positive predictive value of conventional ECG stress testing. Patients who are referred for stress test will perform an ECG stress test on a treadmill, with high-frequency ECG recording from conventional 12 leads using BSP's HyperQ™ System. Conventional 12 lead ECG, as well as HyperQ™ recordings will be provided by the HyperQ™ System. The results of the conventional test and the HyperQ™ data will be compared, using one of three cardiac tests (stress echocardiography, SPECT myocardial perfusion imaging and angiography) as gold standards. Statistical analysis will compare the sensitivity, specificity, PPV and NPV of the conventional and HyperQ™ stress ECG in detecting myocardial ischemia.
