Filter by:The goal of this clinical research study is to compare the effects of sodium bicarbonate to normal saline when used for clearing mucus blockage in patients with airway stents.
The primary objective of this study is to compare platelet reactivity between patients receiving a loading dose of clopidogrel and a reloading dose of prasugrel to patients receiving only a loading dose of prasugrel.
The purpose of this study is to describe the short-and long-tern (i.e. up to 2 years following the index event) AMPs in patients hospitalized for an acute coronary syndrome (i.e. STEMI or NSTE-ACS), and to document clinical outcomes, economic aspects and impact on quality of life of these AMPs in a 'real-life' setting.
This is a single-center, randomized, single-blind, investigator-initiated pharmacological study with a crossover design. Patients with acute coronary syndrome (ST-elevation myocardial infarction, non-ST elevation myocardial infarction, unstable angina) and presenting high on-clopidogrel platelet reactivity as assessed with the VerifyNow assay (platelet reactivity units PRU≥235) 24 hours post percutaneous coronary intervention (PCI), will be randomized after informed consent in a 1:1 ratio to either prasugrel 10mg/d or ticagrelor 90mg twice a day for 15 days. Platelet reactivity assessment will be performed at Day 15±2 days and then a crossover directly to the alternate treatment group for an additional 15 days period, without an intervening washout period will be carried out. Patients will return at Day 30±2 days for platelet reactivity assessment.
The purpose of this study is determine if SCH 530348 2.5 mg tablets containing a high percentage of drug as the free base are equivalent to tablets with the standard percentage when given to participants.
This non-inferiority study aims at comparing Versa® to the reference enoxaparin (Clexane®, Sanofi-Aventis) in patients with high-risk unstable angina and NSTEMI. The main justification is the search for scientific evidence to prove the Versa® effectiveness for this new therapeutic indication, since it is a product with potential for reducing costs, with effectiveness and safety comparable to the reference drug.
The aim of this study is to evaluate whether dabigatran reduces clopidogrel mediated ADP induced platelet aggregation measured by MEA as compared to phenprocoumon after a two-week treatment with either agent.
Although successful, percutaneous coronary interventions (PCI) with stent implantation may be hampered by periprocedural myocardial necrosis. In acute ST-elevation myocardial infarction (STEMI), the reduction of thrombus burden through manual thrombus aspiration (TA) of an occluded coronary artery has been documented to produce an improved myocardial perfusion rate and significant survival advantage. To date, beyond feasibility and safety studies no clinical benefit has been yet documented with the use of TA before stent deployment in the setting of acute coronary syndromes (ACS) outside acute STEMI. The investigators hypothesize that TA before stent deployment reduces the thrombus/plaque burden - as assessed by intravascular imaging systems - in the setting of acute coronary syndromes (ACS) outside acute STEMI.
Patients admitted to hospital with chest pain due to reduced blood flow to heart muscle (diagnosis Acute Coronary Syndrome) can be treated with medication and an angioplasty ± stent procedure, which restores blood flow to the heart. Antiplatelet drugs (Aspirin and Clopidogrel) are blood thinning treatments and research has reported they reduce heart attacks, death and stroke. The investigators know some patients do not respond fully to Clopidogrel but currently patients are not tested for this. The investigators wish to perform a trial to identify those patients who do not respond fully to Clopidogrel and randomise them to either Prasugrel (newer drug) or a higher dose of Clopidogrel. Patients admitted to the hospitals (2 in the UK and 1 in Germany) will be asked for their consent to participate. A blood sample is tested for platelet activity. 1. Low platelet activity result means patient has responded well to Clopidogrel and will continue on the routine dose. They will be entered into an observational registry. Data will be collected of routine blood tests and investigations, medication and procedures. Their GP will be contacted at about 30 days to see if they are alive. 2. High platelet activity results means patient has not responded fully to Clopidogrel. These patients will be randomly allocated to a higher dose of Clopidogrel or new drug Prasugrel. Data will be collected of routine blood tests and investigations, medication and procedures. A hospital visit at 30±5 days is required to assess how patients are doing, medications and occurrence of any events.
OSA may be a modifiable risk factor for cardiovascular disease due to its association with hypertension, stroke, heart attack and sudden death. The standard therapy for symptomatic OSA is continuous positive airway pressure (CPAP). CPAP has been shown to effectively reduce snoring, obstructive episodes and daytime sleepiness and to modestly reduce blood pressure and other risk factors for cardiovascular disease. The overall aim of ISAACC is to determine if CPAP can reduce the risk of heart attack, stroke or heart failure for people with OSA admitted in a hospital for an acute coronary syndrome. Overall objective: To assess the impact of obstructive sleep apnea (OSA) and its treatment on the clinical evolution of patients with acute coronary syndrome (ACS). Primary objectives: 1. To determine if continuous positive airway pressure (CPAP) treatment will reduce the rate of cardiovascular events (cardiovascular (CV) death, non-fatal events (acute myocardial infarction (AMI), non-fatal stroke, hospital admission for heart failure, and new hospitalizations) for unstable angina or transient ischaemic attack (TIA)) in patients with ACS and co-occurring sleep apnea. Secondary objectives: 1. Determine the prevalence of OSA in patients who have suffered an episode of ACS. 2. Other secondary objectives will include the effects of CPAP on: - To evaluate a composite of CV death, myocardial infarction (MI) and ischaemic stroke. - Components of primary composite endpoints - Re-vascularization procedures - To evaluate all-cause death - To evaluate new onset, ECG-confirmed atrial fibrillation or other arrhythmias - To evaluate newly diagnosed diabetes mellitus, according to standard definitions - To evaluate OSA symptoms (Epworth Sleepiness Scale (ESS)) - To evaluate quality of life in patients with ACS (Test EuroQol (EQ-5D). 3. To establish the relationship between the severity and phenotype of patients with OSA and clinical outcomes of ACS. 4. To establish the relationship between CPAP compliance and CV events incidence. 5. To identify biological risk markers that allow us to establish the most important mechanisms involved in cardiovascular complications in these patients. 6. To conduct a cost-effectiveness analysis of the diagnosis and CPAP treatment of patients with ACS who have obstructive sleep apnea.
