Active clinical trials for "Myocardial Ischemia"

The aim of the study is to compare clinical outcomes between intravascular imaging-guided versus angiography-guided percutaneous coronary intervention (PCI) in complex lesions.

Study aim : To compare a novel strategy of lesion preparation with noncompliant balloons before implantation of BVS. Hypothesis: Predilatation with non-compliant balloons could facilitate optimal deployment of BVS. By achieving good scaffold apposition a need for post-dilatation could be significantly reduced. This is expected to result in better short- and long-term outcomes.

The primary objective of this study is to evaluate the in-stent late lumen loss (LLL) at 9 months, defined as the difference between the post-procedure minimal lumen diameter (MLD) and the follow-up angiography MLD, of the Resolute Zotarolimus-Eluting Coronary Stent System compared to Taxus Liberte Paclitaxel-Eluting Coronary Stent System in a real-world all-comer patient population requiring stent implantation.

Kidney transplant candidates are at very high risk for coronary artery disease (CAD). The optimal strategy to monitor and maintain the cardiac fitness of patients awaiting kidney transplantation is unknown. Currently patients undergo annual testing; however, screening for CAD may increase morbidity and mortality by: exposing patients to the risk of angiography and revascularization procedures delaying or excluding patients from life saving transplantation. Before proceeding with a definitive study to determine whether screening is necessary, feasibility will be determined in this pilot study.

Is the surgical treatment of patients with coronary heart disease using the T-graft technique an adequate solution that provides a sufficient myocardial flow reserve? A magnetic resonance examination (MRI) is required.

Psychosocial factors have been found to be associated with an increased risk for coronary artery disease incidence, progression and worse clinical outcomes. Patients with non-significant coronary artery disease (confirmed vascular irregularities, but <60% coronary occlusion) often present with complaints such as chest pain, which warrant screening by coronary angiography (CAG) or computed tomography (CT scan). The prognosis of this group of patients with mild stenosis remains to be investigated in more detail, and we propose that psychosocial factors play a role in the clinical prognosis and patient reported outcomes in this group. A special focus lies within examining personality characteristics, of which Type D personality is a primary predictor variable for prognosis. Type D personality is characterised by high negative affect and high social inhibition. In addition to psychosocial factors (personality, mood state, social support, SES), biomarkers(inflammation, clotting, DNA) as well as standard clinical risk factors (metabolic syndrome, activity level, smoking, medication use, disease severity) will be investigated. The goal of the proposed study is to investigate a preexisting psycho-biochemical risk profile for major adverse cardiovascular events (MACE) and patient perceived symptoms in a group with angiographically or CT-scan confirmed, non-significant coronary artery disease.

The purpose of the study is 1> to compare neointimal stent coverage after OCT-guided vs. Angio-guided PCI, 2> to compare neointimal stent coverage at 3 months after EES vs BES implantation, 3> to determine the duration of dual antiplatelet therapy by OCT measurement at 3 months

This is a prospective, multi-center cohort study of patients with a history of coronary artery disease (CAD) and documentation of either a prior myocardial infarction (MI) or mild to moderate left ventricular dysfunction (LVEF 35-50%). The primary objective of this study is to determine whether biologic markers and ECGs can be utilized to advance SCD risk prediction in patients with CHD and LVEF>30-35%. The overarching goal of the study is to identify a series of markers that alone or in combination specifically predict risk of arrhythmic death as compared to other causes of mortality among this at risk population of coronary heart disease (CHD) patients with preserved left ventricular ejection fraction (LVEF> 30-35%). If biologic or ECG markers are identified that can specifically predict risk of ventricular arrhythmias, then these markers may serve as relatively inexpensive methods to identify those at risk. The public health impact of identifying markers could be quite substantial, leading to more efficient utilization of ICDs and advances in our understanding of mechanisms underlying SCD.

The COMPETE study is a prospective,randomized,two-arm multi-center clinical trial comparing two commercially available coronary stents: Chrono Carbostent Carbofilm™ Coated vs Driver/Micro-Driver Coronary Stent System. In this study, 204 subjects will be included (2:1 randomization Chrono:Driver/Micro Driver) in 6 Italian sites.

A prospective Optical Coherence Tomography (OCT) study on the completeness of strut coverage and vessel wall response, at different time points (3-6-9 Months), following TAXUS Liberte stent implantation (staged procedures) in patients with multi vessel native coronary artery lesions
