Filter by:This is a randomized Clinical Trial to assess the effects of Tai Chi Chuan on blood pressure, respiratory muscle strength and functional capacity in patients after recent acute myocardial infarction.
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 objective of this study is to evaluate the safety and tolerability of two active doses of RGN-352 (thymosin beta 4, Tβ4, Injectable Solution) in patients with acute myocardial infarction receiving percutaneous coronary intervention angioplasty with or without stent placement. Approximately 75 subjects will be randomized to receive one of two RGN-352 doses of 1200 mg, or 450 mg, or placebo, administered iv by iv push daily for the first 3 consecutive days and weekly for 4 more weeks.
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.
This clinical evaluation will study the feasibility and safety of a CE-marked paclitaxel-eluting balloon in primary PCI in patients with a STEMI. Drug eluting balloons provide the potential advantage of delivering a anti-proliferative drug, without the disadvantage of leaving a coronary stent, in STEMI patients treated with primary PCI.
- Aim The AVOID (Air Verses Oxygen In myocardial infarction) trial is designed to determine if the withholding of routine oxygen therapy in patients with acute heart attack leads to reduced heart damage compared to the current practice of routine inhaled oxygen for all patients. - Background There is evidence supporting and refuting the current practice of providing oxygen to all patients with acute heart attack. A recent summary of clinical trials suggested that oxygen may increase the degree of heart damage during heart attack. It also highlighted that the few trials into oxygen therapy were performed before the use of modern medications and procedures to treat heart attack and that further studies were urgently needed, using contemporary practices. - Design A total of 334 patients will participate in this randomized controlled trial. Patients in this study will receive the best current management and care for their condition. Patients will be randomized to routine pre-hospital care with oxygen therapy vs pre-hospital care without oxygen therapy. Patients will then receive standard hospital care, aside from allocated oxygen or no oxygen therapy. The primary outcome measure of heart damage will be investigated using routine blood tests. With additional information gathered from other aspects of routine heart care including coronary angiogram, electrocardiograms and complications of hospital stay. Patients will be followed up at 6 months to determine any longer term effects of treatment.
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.
Current antiplatelet therapy in acute coronary syndrome have a focus on the dual antiplatelet therapy including aspirin and clopidogrel. However, the patient's drug resistance of aspirin and clopidogrel is the important cause of poor clinical prognosis. Therefore, recently, clinical research about the triple antiplatelet therapy including cilostazol is actively conducted. But, clinical research about triple antiplatelet therapy for acute myocardial infarction is inadequate situation, and the ideal duration of triple antiplatelet therapy has been actively discussed. Therefore, we try to evaluate the clinical outcomes of triple antiplatelet therapy in acute myocardial infarction patients undergoing percutaneous intervention with drug eluting stent compared with dual antiplatelet therapy and investigate ideal duration of triple antiplatelet therapy through this research.
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.
