Active clinical trials for "Coronary Artery Disease"

To evaluate the role of the genetic variant 2C19*2 on the pharmacodynamic response as assessed by optical aggregometry and on the pharmacokinetic response as assessed by measuring active metabolites following an oral administration of a loading dose of 300/900mg of clopidogrel in patients with established coronary artery disease.

The objective of this study is to evaluate the completeness of struts coverage and vessel wall response to the new generation JACTAX drug-eluting stent vs Taxus stent in de novo coronary artery lesions at 6 months post index procedure. To investigate the completeness of the coverage as well as the number of uncovered stent struts per section, high resolution (~ 10-15 µm axial) intracoronary Optical Coherence Tomography (OCT) will be used.

Exercise training in patients with coronary artery disease is able to correct several risk factors. Furthermore endothelial function can be improved. There are some hinds for improved collateral circulation after exercise training, nevertheless there is no study showing significant improvement/ increase in coronary collaterals. This might be due to technique of collateral measurement. Therefore we conduct a study were coronary blod flow before and after 4 weeks of exercise training were measured.

All patients undergoing elective or sub-acute PCI are screened by MULTIPLATE test for clopidogrel low-responsiveness after receiving 600 mg clopidogrel the day before. A cut off value has previously been established. Only low-responders with Multiplate values above the cut off value are included in the study. The patients are randomized to either clopidogrel 150 mg once daily or Prasugrel 10 mg (age > 75 og bodyweight < 60 kg 5 mg)once daily for 30 days after the procedure. Follow up will be at 30 days after PCI were another MULTIPLATE test will be performed. Primary endpoint:Platelet inhibition (by MULTIPLATE) after 30 days of intensified antiplatelet therapy. Clinical endpoints such as bleeding complications (GUSTO, TIMI) during treatment, and major adverse cardiac events (MACE) at 30 days will be collected and reported but the study size does not allow for formal statistical analysis The study ends by the 30 days follow up visit and all patients continue with clopidogrel 75 mg once daily for another 11 months (not study related)

The purpose of this study is to evaluate whether the newly-approved everolimus-eluting stent is not inferior to the sirolimus-eluting stent in terms of the rate of target-lesion revascularization at 1-year and death or myocardial infarction at 3-year after stent implantation in the real world clinical practice.

The changes in risks of developing coronary heart disease in patients with morbid obesity after different weight loss interventions have not been extensively studied. The primary objective of this study is to investigate whether an intensive lifestyle intervention program in a tertiary care clinic (Spesialsykehuset for Rehabilitering) is comparable with a 7-week low-energy-diet followed by bariatric surgery in decreasing the risk of cardiovascular disease in these patients.

Randomized clinical comparison of the serolimus eluting Cypher stent and the zotarolimus eluting Endeavor stent.

To evaluate the procedural, short and long term clinical outcomes of the TAXUS stent compared to Cypher stent in coronary arteries of ≥ 2.5 and ≤ 3.75 mm in the reference vessel diameter with a lesion of ≤ 46 mm (by visual observation) in routine clinical settings in Japan.

This study will test the hypothesis that elective use of the Intra-Aortic Balloon Pump (IABP) in patients undergoing high-risk Percutaneous Coronary Intervention (PCI) will reduce the rate of in-hospital major adverse cardiac and cerebrovascular events compared to patients who are managed without planned insertion of IABP.

The purpose of the DEBIUT study is to assess procedural, clinical and angiographic outcomes of: Provisional T-stenting use for dilation the Paclitaxel-eluting PCI-balloon (DiorTM) in comparison to dilation with a standard balloon prior to the implant of the Liberty Bare Metal Stent in bifurcation lesions (with side branch involvement). Comparison of the results above with the results of using a standard balloon prior to provisional T-stenting with the Paclitaxel-eluting stent TaxusTM LibertéTM.
