Filter by:This is a single-center, randomized, single-blind, investigator-initiated, pharmacological study with a parallel design. Patients with ST elevation myocardial infarction undergoing primary percutaneous coronary intervention and presenting high platelet reactivity as assessed with the Verify Now P2Y12 assay-Accumetrics(Platelet Reactivity Units -PRU≥235) at 2 hours post-clopidogrel 600mg LD (Day 0), as assessed with the Verify Now P2Y12 assay, will be randomized after informed consent, in a 1:1 ratio to the following treatment groups: Group Α: Clopidogrel 150mg per day,starting from Day 1 until Day 5 (5 days after randomization) Group Β: Prasugrel 60 mg immediate loading (on Day 0) followed by 10mg/day starting from Day 1 until Day 5 (5 days after randomization). Platelet reactivity assessment will be performed 2 hours after randomization (Day 0), 24 h after randomization (Day 1) and on Day 5. Documentation of major adverse cardiac events (death, myocardial infarction, stroke, revascularization procedure with PCI or CABG)and serious adverse events (bleeding, other adverse events)will be performed until Day 5.
This is a single-centre, open-label prospective randomized pharmacodynamic investigation of 2 antiplatelet regimens in patients undergoing coronary intervention for ST segment elevation myocardial infarction(STEMI): 1. Tirofiban bolus only or bolus followed by 2 hour infusion on top of 600 mg clopidogrel or 60 mg prasugrel. 2. Prasugrel given at 60 mg.
An estimated three million people are affected by chronic obstructive pulmonary disease (COPD) in the UK, giving it a prevalence of 1.5% of the population in 2007/08. COPD accounts for approximately 30,000 deaths each year in the UK and is an important co-morbidity in those dying from other smoking related diseases, most commonly ischaemic heart disease and lung cancer. The National COPD audit showed a very high level of co-morbidity, the association with cardiovascular disease being particularly strong with 51% of patients with cardiovascular disease having been admitted for COPD within the preceding 24 months. Patients with COPD are at increased risk of myocardial infarction compared to the general population. Although this increase in cardiovascular risk exists, it is not clear is whether survival after myocardial infarction is different in patients with and without COPD and what factors contribute to this survival difference. Differences in survival may arise due to differences in prescribing certain drugs such as beta-blockers, differences in prevalence of risk factors (e.g. current smoking status) or increased COPD events such as exacerbations which themselves are associated with increased mortality. The investigators primary aim is to investigate whether survival after first myocardial infarction is shorter in patients with COPD than those without COPD and to establish reasons for these differences in survival.
Acute myocardial infarction is generally caused by a thrombotic occlusion of coronary arteries. Primary aim of early therapy is a fast and complete reperfusion of the infarcted myocardium.
This randomized, double-blind, placebo-controlled study will evaluate the efficacy and safety of RO4905417 in patients with non ST-elevation myocardial infarction (Non-STEMI) undergoing percutaneous coronary intervention (PCI). Patients will be randomized to receive an intravenous infusion of either 5 mg/kg RO4905417 or 20 mg/kg RO4905417 or placebo before PCI. Follow-up will be for 4 months.
ST segment elevation myocardial infarction (STEMI) is a common presentation of heart attack constituting approximately 30% of all cases. Clinical guidelines around the world support the prolonged use of secondary preventative medications including aspirin, clopidogrel, statin, beta-blocker and angiotensin blockers with the highest recommendations. While in-hospital and discharge prescription rates are excellent, adherence to these essential life-saving medications is far less than ideal, even a few months following hospital discharge. The investigators plan to capitalize on the existing structure of the SMART-AMI project already underway in LHIN IV to undertake a randomized controlled trial evaluating a reminder sent on behalf of the interventional cardiologists, delivered by mail, at 1, 2, 5, 8, and 11-months post-discharge, reviewing the evidence for life-saving cardiac medications and urging long-term adherence to secondary preventative cardiac medications. This will be sent to the family physician and the patient, using audience-appropriate language. If the DERLA-STEMI project is accepted by physicians and patients, found to be both feasible and effective, then this simple and low-cost intervention will be studied in all patients with an abnormal coronary angiogram.
This study will evaluate change in heart muscle function from baseline to three months and twelve months in participants who present with a heart attack and a completely occluded coronary artery. These subjects will be randomized to receive standard Percutaneous transluminal coronary angioplasty (PTCA)/Stenting to open the artery or routine PTCA/Stenting plus post conditioning. Post conditioning commences immediately upon reperfusion using four cycles of thirty second inflations with a standard angioplasty balloon followed by a thirty seconds of reperfusion. The investigators hypothesize that Postconditioning reduces the size of the heart attack when utilized with successful primary Angioplasty/stent.
The investigators wish to examine whether a novel 'nanoparticle' of iron oxide, administered intravenously allows an area of heart muscle damage after heart attack to be visualised using a magnetic resonance scanner.
The aim of the FOCUS project is to test the Fixed Dose Combination concept for cardiovascular prevention in populations of different socio-economic characteristics. At the same time, FOCUS aims to understand the factors determining inappropriate prescribing for secondary cardiovascular prevention and those for poor patients adherence to treatment. This will allow FOCUS to establish recommendations for a better use of medication in patients with ischemic heart disease. In addition, after a successful completion of FOCUS, secondary prevention medication will be available and affordable for a large number of patients in both developed as well as developing countries. There are two Phases in this study: Phase 1: Is a descriptive, non interventional study. Phase 2: Is an interventional, randomized trial with prospective economic evaluation.
The purpose of this study is to test whether early pre-reperfusion metoprolol administration in patients suffering and acute myocardial infarction might reduce the size of myocardial necrosis.
