Active clinical trials for "Acute Coronary Syndrome"

This study has the following objective: To identify related factors to hospital mortality in patients with ST-segment elevation acute myocardial infarction submitted to pharmacoinvasive strategy within a structured healthcare network.

This is a multicenter, prospective, observational investigation, focusing of antiplatelet treatment in patients with moderate to high risk acute coronary syndrome (TIMI risk score ≥3)subjected to percutaneous coronary intervention (PCI), being conducted in 7 PCI capable hospitals in Greece. Data concerning patients' demographic, clinical/procedural characteristics and contraindications/special warnings and precautions to P2Y12 inhibitors are collected during initial hospitalization. Study involves 3 follow-up visits after hospital discharge(Day 30, at 6 months and at 12 months) where data on major adverse cardiac events (death, myocardial infarction, stroke, urgent revascularization procedure with PCI or CABG), bleeding events(according to Bleeding Academic Research Consortium criteria)and adherence to antiplatelet treatment are collected. In patients under ticagrelor or prasugrel treatment, platelet reactivity measurement with VerifyNow assay will be performed at Day 30

This register will evaluate the use of different antithrombotic therapies, combinations of different drugs routinely used during any stage of hospital admission, with their timing, dosage and mode of administration, in patients with a diagnosis of Acute Coronary Syndrome in the Italian Coronary Care Unit during a study period of three weeks

Our research will examine whether the presence or absence of serial electrocardiogram (ECG) changes aids in reclassifying participants' risk for major adverse cardiac events (MACE) over and above serial blood testing.

To develop and implement quality improvement programs for the treatment of acute coronary syndrome (ACS) in China based on the successful experience of the AHA-Get with the Guidelines program. This program will use data collection, analysis, feedback, and process improvement to extend the use of evidence-based guidelines throughout the healthcare system and improve patient care of acute coronary syndrome.

The whole blood Thrombelastograph (TEG®) Platelet Mapping™ assay measures clot strength, maximal amplitude (MA), reflecting maximal platelet function, and detects the reduction in platelet function, presented as percentage inhibition, by both aspirin and clopidogrel. A study reported that the TEG® can be used as routine monitoring of the variability in ADP receptor inhibition and of antiplatelet therapy. Therefore, using TEG Platelet Mapping assay, we could find out the perioperative clopidogrel responsiveness of the patients with ACS undergoing OPCAB. The purpose of this study is to determine whether the rate of the major adverse cardiac events (MACE, a combined endpoint of MI, revascularization and cardiac death) is higher in the patients with high degree of clopidogrel resistance, who are scheduled to undergo the OPCAB due to ACS.

This clinical investigation is designed to demonstrate the performance characteristics of the RAMP® cardiac tests analyzed on the RAMP® 200 by non-laboratorial Operators at the point-of-care when compared to the results for the same samples analyzed on the RAMP® Reader.

The UNICORN consists of two collaborating biobanks, one in Utrecht and one in Singapore. From these two sites we include all patients who undergo a coronary catheterization for any reason. At the moment of catheterization we draw blood, which will be stored in a biobank and we collect clinical characteristics. Patients are followed-up for 5 years for the occurrence of major cardiovascular events. By including from two sites in the world we include 4 major ethnic groups: Caucasians, Chinese, Indians and Malays. We aim at including at least 2000 patients per ethnic group. Our hypothesis is that there are differences in the risk factor burden, clinical presentation of CAD, and biochemical patterns in the blood among the ethnic groups. Furthermore, this biobank offers a platform for multi-ethnic biomarker discovery.

The primary objective of the UPSTREAM Registry is to address the data gap regarding the course of NSTEMI (Non-ST-Elevation Myocardial Infarction)between ED (Emergency Department) arrival and diagnostic angiography in detail, by characterizing and following the ED and peri-ED use of advanced OAP (Oral Anti-Platelet) agents. In addition to exploring ED treatment patterns and success of both ischemic and bleeding risk stratification prior to definition of the coronary anatomy, data generated via the UPSTREAM registry will allow plausible attribution of ischemic and bleeding outcomes to pre-catheterization antiplatelet therapy in the management of NSTEMI. This registry further seeks to demonstrate that contemporary use of upstream ticagrelor is associated with an economically-sound utilization of hospital resources, and smooth transition of care into the outpatient, secondary prevention setting for the first 30 days after hospitalization. Finally, it will allow characterization of patient selection factors and processes for ticagrelor vs alternative OAP agents, carrying out that descriptive comparison through discharge. Patients transferred in to an UPSTREAM hospital are eligible for inclusion, but the timing for OAP agent administration and diagnostic catheterization begin with ED care at the first hospital.

TRACE is a Multicentre Retrospective Study planned to gather follow up data for a period of 1 year in order to understand anti-thrombotic management patterns and outcomes of Acute Coronary Syndrome patients in India. This retrospective study is designed to provide a rapid and quick analysis of the existing database of ACS patients. So as to ensure quality check in the study, a pilot study will be conducted with around 500 patients at 10 centres across India and based on the meaningful results of the pilot study, full retrospective multi-centric study will be initiated at various selected centres across India. This study will use available registry data from a defined time period of Jan 2007-Dec 2009.
