Filter by:This novel fibrinolytic agent is a 136 amino acid single chain protein secreted by some strains of Staphylococcus aureus and readily produced by recombinant DNA technology. Two natural variants of recombinant staphylokinase, THR-100 and SakSTAR, have been developed for investigational use in preliminary trials. Like SK, it forms an equimolar complex with plasmin which in turn activates plasminogen to plasmin. Unlike SK, the complexed, activated molecule (which undergoes proteolytic cleavage of the first ten amino acids to generate active staphylokinase) has a high degree of fibrin-selectivity in a human plasma milieu. This fibrin-selectivity is due in large measure to potent activation at the clot surface by trace amounts of plasmin, and rapid inactivation of the circulating complex by antiplasmin. Hence, it provides an interesting and promising alternative therapy.
The purpose of this study is to investigate the safety and efficacy of intracoronary human umbilical Wharton's jelly-derived mesenchymal stem cell (WJ-MSC) transfer in patients with ST-segment elevation acute myocardial infarction.
To compare rheolytic thrombectomy (RT) with manual thrombus aspiration (MTA) in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing primary PCI. Occlusive thrombosis triggered by a disrupted or eroded atherosclerotic plaque is the anatomic substrate of ST-segment elevation myocardial infarction (STEMI). Due to this substrate, macro- and microembolization during percutaneous coronary intervention (PCI) in AMI is frequent and may result in obstruction of the microvessel network, and decreased efficacy of reperfusion and myocardial salvage. Direct stenting without predilation or postdilation is the most simplistic approach to the problem of embolization, and may decrease embolization and the incidence of the no-reflow phenomenon. Other approaches to the problem of microvessel embolization include thrombectomy before stent implantation, and the use of antiembolic devices (filters and occlusive devices with retrieval of thromboembolic material after stent implantation). Most concluded studies on removing of thrombus before stenting used manual aspiration catheters and meta-analyses derived from these studies support the use of manual thrombus aspiration (MTA) catheters in the setting of primary PCI. MTA is currently recommended in the setting of primary PCI as a Class II b recommendation; level of evidence B. Rheolytic thrombectomy (RT) using multiple jets of saline solution and aspiration based on the Bernoulli effect has been proven to be effective in decreasing major adverse events during PCI in saphenous vein grafts or native coronary arteries with angiographic evidence of thrombus, and 2 out of 3 concluded studies have shown a better reperfusion and clinical outcome in patients randomized to RT as compared to control.
The purpose of this study is to evaluate the safety and tolerability of 42037788 (CNTO 0007) in patients who have suffered a stroke. The study is not designed to establish efficacy, although preliminary explorations will be conducted.
This study is performed to observe the incidence of major cardiovascular events in Korean patients with AMI after giving pitavastatin 2mg and 4mg longer than 1 year.
In patients with ST elevation myocardial infarction (STEMI)treated with primary percutaneous coronary intervention (PPCI) a subset with low risk for late complications can be identified. Early discharge (<72h) of these patients can compromise initiation of prophylaxis, information and other investigations. The researchers want to investigate prospectively whether early discharge compared to regular care have comparable patient centered outcomes at 30 days follow-up.
To determine whether higher as compared with lower maintenance doses of clopidogrel can adequately improve the degree of platelet inhibition in carriers of a reduced-function CYP2C19 allele.
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.
The primary objective is to evaluate the safety and effectiveness of the IK-5001 device for the prevention of ventricular remodeling and congestive heart failure when administered to subjects who had successful percutaneous coronary intervention with stent placement after ST segment elevation MI (STEMI).
This study is being carried out to see if a new drug called ticagrelor given twice daily in addition to the ASA therapy decreases the frequency of cardiovascular events (e.g., death from heart disease, heart attack, or stroke).
