Filter by:The central hypothesis for this work is that platelet - leukocyte interactions play a critical role in the pathogenesis of acute ischemic events. The primary objective of the study is to determine if early, high-dose administration of the HMG-CoA reductase inhibitor rosuvastatin in the setting of acute coronary syndrome and percutaneous coronary intervention exerts beneficial vascular effects by reducing platelet - leukocyte interactions.
It is an exploratory study evaluating a biological effect (stent strut coverage) using a novel technology such as OCT without any clinical implication.
This is the continuation of previous study (registration number: NCT00844987) which revealed that hepatocyte growth factor (HGF) is a very early, good marker of myocardial injury and prognostic factor for post myocardial infarction (MI) cardiovascular events presence in long-term follow-up. Due to potentially very important implication of the results of previous study it was decided to continue research of HGF in patients with MI. Now, is scheduled to examine 100 consecutive patients with STEMI. HGF assessments will be performed just after admission to hospital, 1h and 24h later and before discharge. Two follow-up visits were planned i.e. at 3 and 6 months after MI. During hospitalization and at 6 month visit the echocardiography examination will be performed. The composite primary endpoint consists of cardiovascular events observed during hospital course and in long term-follow-up.
Patients who have experienced and survived non-ST segment elevation acute coronary syndromes are often prescribed a combination of aspirin and clopidogrel to thin the blood and prevent further acute coronary episodes. Both clopidogrel and aspirin may cause stomach bleeds and so a prophylactic proton pump inhibitor is frequently co-prescribed in order to prevent such bleeds. Recent mechanistic and observational studies suggest proton pump inhibitors may reduce the effectiveness of clopidogrel and so patients may not benefit as much as expected from combined aspirin and clopidogrel. The investigators propose a cohort study of patients prescribed clopidogrel + aspirin. Amongst these patients the investigators will measure the relative rate of acute coronary syndrome and death comparing patients with and without proton pump inhibitor treatment. To provide a more complete picture of the risks and benefits of treatment the investigators will also measure the relative rate of stomach bleeds in the same groups of patients. In addition, whether the inhibitory effect of proton pump inhibitors on the protective effect of clopidogrel is due to their inhibition of drug metabolising enzymes will be explored by assessing the effects of other drugs that inhibit the same enzymes.
The objective of this study is to verify the relationship between coronary plaque regression and cardiovascular prevention in long term follow up of the Japan Assessment of Pitavastatin and Atorvastatin in Acute Coronary Syndrome (JAPAN-ACS) study [NCT00242944]. In addition, the effect of serum lipid levels or different type of statins on cardiovascular prevention will also be examined.
This is a randomized, open trial comparing post discharge interventions by community health workers (CHW) to standard care in acute coronary syndrome (ACS) patients. This trial will be conducted in 10 hospitals in India/different parts(both secondary and tertiary care). A total of 800 patients will be recruited, with equal allocation to SPREAD interventions and control groups (usual care)
Cardiovascular disease remains the most pressing healthcare issue for developed countries and is becoming so for developing countries. There are a number of chronic therapies available for long-term management of risk. Short term therapies for subjects with an acute event, such as an episode of acute coronary syndrome (ACS), are focused on reperfusion and removing thrombus but most subsequent events are caused by atherosclerotic plaque rupture at a different site. There are no approved therapies that can rapidly reduce the burden of unstable, inflamed plaque in the overall coronary vascular bed. HDL has multiple actions that could lead to atherosclerotic plaque stabilization, such as rapid removal of large quantities of cholesterol from the vasculature, improvement in endothelial function, protection against oxidative damage and reduction in inflammation. This study will assess the effects of CER-001, an ApoA-I-based HDL mimetic, on indices of atherosclerotic plaque progression and regression as assessed by intravascular ultrasound (IVUS) measurements in patients with (ACS).
In this study, multimodal imaging of atherosclerosis and dosage of new circulating biomarkers will be used to compare patients with stable or unstable coronary artery disease
This open-label study, prospective, randomized trial evaluating the acute (in-hospital) pleiotropic and clinical effects of a hydrophilic statin (rosuvastatin) in patients with acute coronary syndrome
Accurate detection of a heart attack (an acute myocardial infarction) is one of the most pressing needs in medicine. Recordings of the electrocardiogram (ECG) (electrical activity of the heart) are one of the first tools used to diagnose a heart attack, but the ECG is not very accurate, especially at the beginning of a heart attack. A new technique for analysing a special part of the ECG may provide more accurate detection of a heart attack. The study hypothesis is that this new technique, the HFQRS analysis, will provide important additional information to that available from the regular ECG.
