Filter by:This double-blind, randomized, placebo-controlled, multi-center study will evaluate the safety and efficacy of dalcetrapib in patients hospitalized for an acute coronary syndrome (ACS). Treatment will be initiated within 1 week after the ACS. Patients will be randomized to receive dalcetrapib 600 mg as daily oral doses or matching placebo. The anticipated time on study treatment is 20 weeks.
The present pilot study aims to investigate the effectiveness of the preoperative infusion of levosimendan in patients with impaired left ventricular function undergoing coronary artery bypass grafting.
This study aimed to examine the prevalence of glucose metabolism disorders (GMD)in the patients with coronary artery disease and the relationship between different GMDs and coronary artery disease (CAD).
The purpose of this trial is to determine if by structured telephone based health coaching programme supported by remote monitoring system among type 2 diabetes, coronary artery disease and heart failure patients the investigators are able to improve their quality of life as measured by the SF-36 questionnaire and reduce a value of HbA1c under 6,5 % among those type 2 diabetes patients who had elevated value of HbA1c when recruited.
The purpose of this two part study is the assessment of the performance of the XIENCE V® Everolimus Eluting Coronary Stent System (XIENCE V® EECSS) in the treatment of the specific setting of patients with Multi-Vessel Coronary Artery Disease (MVD).
This study is designed as a prospective, randomized, multi-center trial to demonstrate an inequality between IVUS-guided versus angiography-guided implantation of everolimus-eluting stents(EES) at long lesions(> 28 mm) in clinical outcomes at 12 months as a primary objective and safety of 6- month dual antiplatelet therapy following EES implantation in comparison with a 12-month dual antiplatelet therapy.
The purpose of this trial is to assess the safety and efficacy of the Nile PAX® Drug Eluting Coronary Bifurcation Stent System for the treatment of single de novo bifurcation lesions in native coronary arteries with a main branch reference vessel diameter of 2.5-3.5 mm and side branch reference vessel diameter of 2.0-3.0 mm.
Pressure intermittent coronary sinus occlusion (PICSO) in patients with coronary artery disease improves collateral flow index to higher than 30%. PICSO used in this patient population is safe, feasible and effective. Safety, feasibility and effectiveness will be tested by periprocedural and logistic data.
Obstructive sleep apnea (OSA) is a respiratory disorder of sleep characterized by recurrent episodes of complete or partial upper airway obstruction, leading to intermittent oxygen deprivation. This results in sympathetic activation and surges in blood pressure, production of vasoactive substances, as well as activation of the inflammatory and procoagulant pathways. Epidemiological evidence indicates the prevalence of OSA is higher in patients with coronary artery disease than in the general population. The investigators recently showed that 65.7% and 41.9% of the Singapore patients admitted with myocardial infarction were found to have previously undiagnosed OSA and severe OSA, respectively. In a 10-year follow-up epidemiological study, OSA was independently associated with a higher prevalence of fatal and non-fatal cardiovascular events among the otherwise healthy general population. The investigators further showed that in patients who have undergone primary percutaneous coronary intervention for acute myocardial infarction, OSA was an independent predictor of future adverse event rates. Despite the observed association between OSA and adverse cardiovascular outcomes, the underlying pathophysiological mechanisms remain unclear. In this proposal, the investigators aim to elucidate the relationship between OSA and composition of coronary atherosclerotic plaques.
Clopidogrel administration is considered standard of care in patients with stable coronary artery disease post PCI. However , a significant proportion of patients is considered clopidogrel resistant and this is shown to be accompanied by future adverse events. The hypothesis of the study is to define among consecutive outpatient clinics individuals with stable coronary artery disease being on chronic clopidogrel treatment, those that are clopidogrel resistant, as assessed with the VerifyNow point of care assay. Clopidogrel resistant patients will be randomized in a 1:1 fashion to either prasugrel 10mg or clopidogrel 150mg daily. Platelet reactivity will be assessed at Day 14, when treatment crossover will be performed without a washout period. At Day 28 platelet reactivity will be assessed as well.
