Filter by:The purpose of this study is to evaluate possible mechanisms of aspirin resistance at a molecular level in aspirin-treated patients with coronary artery disease. We hypothesize that certain patient characteristics associate with aspirin resistance. In addition, we will compare the effects of enteric-coated aspirin and chewable aspirin.
Using blood testing and cardiac magnetic resonance imaging (MRI), the investigators aim to determine if there are necrotic areas of myocardium in participants who complete a marathon. In addition, the investigators aim to describe the acute and chronic structural abnormalities that occur as a result of endurance training. The study hypothesis is that myocardial necrosis is present in runners completing a marathon competition.
The primary objective of the RESOLUTE international registry is to document the safety and overall clinical performance of the Resolute Zotarolimus-Eluting Coronary Stent System in a 'real-world' patient population requiring stent implantation.
The objective of this study is to compare the safety and effectiveness of two different approaches to treat bifurcational lesions with CYPHER SELECT™ Sirolimus-eluting Balloon-expandable Coronary Stent , Cordis Corp): a) the "crushing" technique to stent both branches vs. b) a provisional T stenting technique of the side branch.
Serum NGAL has been described as a biomarker of neutrophil activation and an inflammatory marker which correlates to obesity and its metabolic complications. Since neutrophil activation has been implicated in the pathogenesis of coronary artery disease, the investigators hypothesized that serum NGAL levels would be higher in patients with CAD and that serum concentration would correlate with the extent of CAD as documented by coronary angiography, serving as a potential biomarker of the severity of CAD.
Despite remarkable gains in treatment over the last decade short-term mortality for those who survive to hospital with AT-elevation acute myocardial infarction (STEMI) remains high (5%-10%). Different studies have pointed out that reperfusion (intravenous fibrinolysis or percutaneous coronary interventions (PCI) and its timing are critical in decreasing STEMI patients' mortality. Studies of prehospital 12 lead electrocardiograms (12 lead PHECG) with advance emergency department (ED) notification suggest that there is a time to treatment advantage with this intervention. The use of 12 lead PHECG is not currently universal and part of standard treatment throughout the province. The purpose of the study is to follow STEMI study subjects during standard treatments and to compare the outcomes of subjects that received 12 lead PHECG with advanced ED notification in mixed rural/urban areas with outcomes of subjects treated in areas with only 3 lead PHECG monitoring and indirect ED notification. The investigators hypothesize that there will be a survival benefit for study subjects with 12 lead PHECG and advance ED notification in rural and urban environments through a reduction in door-to-reperfusion time and that 12 lead PHECG will be a cost-saving technology for the province of Ontario.
The INDICOR study is a controlled, prospective, multicenter, randomized, two arm phase-II real world study assessing the acute, 6 months, and 12 months and 3 year outcome of cobalt-chromium stent (Coroflex Blue) deployment followed by Paclitaxel-eluting PTCA-balloon dilatation (SeQuent Please) and of Paclitaxel-eluting PTCA-balloon dilatation (SeQuent Please) followed by cobalt-chromium stent (Coroflex Blue) deployment for the treatment of de-novo and restenotic lesions in native coronary arteries. The study will be conducted in India.
The purpose of this study is to determine whether aspirin and clopidogrel resistance measured with Multiplate function analyser has a good correlation with incidence of major adverse cardiac events in patients with coronary artery disease (CAD).
This study is being conducted to examine the effect of AZD6140 on the levels of certain chemicals in subjects' blood and urine.
The aim of AUTAX study is to investigate the frequency of MACCE in patients with multivessel disease and multiple Taxus stent implantations in the "real world" stenting at 30 days, 6 and 12 months at 2 year follow-up. Because multivessel stenting using DES has been limited due to economic considerations, the secondary aim is to enhance experience in multivessel stenting with drug-eluting stents in order to improve short- and long-term outcomes of the patients with severe multiple coronary artery stenoses. The objectives of the study are: 1. To determine the frequency of MACCE at 30-day, 6 and 12-month and at 2 year clinical follow-up after multivessel intervention with drug-eluting stents in a prospective patient cohort.. 2. To determine the rate of in-stent restenosis, target lesion and target vessel revascularization (angiographic measures) 6 months in patients with multiple DESs in multiple lesions. 3. To investigate the clinical and angiographic outcomes after implantation of multiple DESs in the subgroup of patients with accompanying diseases (diabetes mellitus, renal insufficiency) with known high restenosis and late complication rate. 4. To evaluate potential cost burden in attempting a strategy of complete revascularization by multiple DES in patients with multivessel disease.
