Active clinical trials for "Acute Coronary Syndrome"

The guidelines of clinical practice, based on the randomized studies, recommend an invasive strategy in non-ST elevation acute coronary syndrome (NSTEACS). However, patients with comorbidities are excluded from the randomized studies and the observational registries showthat patients with comoribidities undergo fewer cardiac catheterizations. The aim is to investigate the benefit of the invasive strategy in patients with NSTEACS and comorbidities. Patients hospitalized with NSTEACS, older than 70 years and with significant comorbidities, will be included. The latter will be defined as at least 2 of the following: peripheral artery disease, cerebral vascular disease, dementia, chronic pulmonary disease, chronic renal failure and anemia. The included patients will be randomized to an invasive (routine coronary angiogram) or conservative (coronary angiogram only if recurrent or inducible ischemia) strategy. All patients will receive medical treatment according to current recommendations. The main outcome will be death, reinfarction or readmissions by heart cause at one-year follow-up. The hypothesis is that an invasive strategy will improve prognosis in patients with NSTEACS and comorbidities.

The purpose this study is to assess whether a tirofiban regimen of a high-dose bolus plus a shortened infusion duration compared to label-dosing eptifibatide in patients undergoing percutaneous coronary intervention (PCI) is associated with a non-inferior composite rate of death, PCI-related myocardial infarction, urgent target vessel revascularization or in-hospital major bleeding within 48 hours following PCI or hospital discharge, whichever comes first.

Previous trials have demonstrated that the use of physiological assessment of stenosis severity using fractional flow reserve (FFR) is superior to angiographic assessment in percutaneous coronary intervention (PCI) and improves clinical outcome. Despite the clinical utility, FFR is used only in 10-15% of patients today. The main reasons for the low adoption rate of FFR are the prolonged procedural time, Adenosine related discomfort and cost associated with Adenosine. Instantaneous Wave-Free ratio (iFR®) is a novel method to assess coronary lesions for functional significance. The main benefits of the method compared to FFR are that the measurement is instantaneous and does not require Adenosine infusion. Thus, the patient does not experience any discomfort from the measurement and procedural time could be shortened compared to when using FFR. This could potentially increase the adoption rate of physiologic assessment of coronary lesions. The aim of this trial is to compare the clinical outcome of patients assessed by iFR® with patients assessed by FFR. Furthermore, the trial will be conducted as a registry based randomized clinical trial (RRCT) which is a novel strategy to conduct clinical trials. The randomization will occur online in the Swedish angiography and angioplasty registry (SWEDEHEART) using a web based platform.

The observatory FAST MI 2010 proposes to establish a cohort of 3500 patients recruited prospectively over a period of 2 months. Patients will be followed up at 1 month and then followed annually for 10 years. Patients should have agreed to participate in the study, participation in the protocol, or refusal to participate will not affect the therapeutic approach of the physician. The study of genotypic or phenotypic characteristics will not change the therapeutic approach of health care teams.

Ticagrelor is a new, reversible binding, anti-platelet medication. Anti-platelet medications work to prevent the formation of blood clots. Ticagrelor is being developed as a treatment for patients with acute coronary syndrome (ACS). ACS is a term that is used to describe both heart attacks in progress or the imminent threat of a heart attack. ACS is usually caused by the formation of a blood clot in an artery that partially or totally blocks the blood supply to a portion of the heart muscle. Ticagrelor will be compared with clopidogrel to determine which drug, when either is used in conjunction with aspirin, is better at reducing deaths from vascular causes, future heart attacks and/or strokes in patients with ACS.

During the 6-month period 119 patients with acute coronary syndrome, were randomized to either stent graft group (n=40), sirolimus eluting stent group (n=39), or bare metal stent group (n=40). Demographic, angiographic and procedural characteristics were similar for all three groups. The incidence of 6-month major adverse coronary events were analysed.

The aim of the study is to assess whether a decision aid that is currently used in hospitals across Greater Manchester to determine how likely it is that a patient has a serious heart problem is still accurate in the pre-hospital environment.

In this proof-of-concept study, the investigators will assess the ease and usefulness of a positive psychology program in patients with acute coronary syndrome and less-than-optimal adherence to health behaviors. The investigators believe that positive psychology (a field that studies boosting positive emotions rather than simply reducing negative emotions) will help this cardiac population to be more healthy. The investigators want to determine whether this positive psychology program has the potential to be an adjunctive treatment for cardiac populations.

Aim of the randomized, open-label, multicenter ISAR-REACT 5 trial is to assess whether ticagrelor is superior to prasugrel in patients with acute coronary syndrome and planned invasive strategy in terms of clinical outcomes.
