Active clinical trials for "Acute Coronary Syndrome"

Study objectives To compare the safety and long-term efficacy of coronary stenting with biostable polymer drug-eluting stent (Promus PremierTM, Xience Alpine®, Resolute Onyx®) with biodegradable polymer drug-eluting stent (Biomatrix®, Biomatrix Flex®, Nobori®, Ultimaster®, Synergy ® and Orsiro®) in patients with acute coronary syndrome To compare the efficacy and safety of 5 mg prasugrel maintenance therapy compared with 10 mg prasugrel maintenance therapy in patients with acute coronary syndrome undergoing percutaneous coronary intervention Study design : Prospective, open-label, 2-by-2 multifactorial, randomized, multicenter trial to test the following in CHD patients Non-inferiority of biostable polymer drug-eluting stent (Promus PremierTM, Xience Alpine®, Resolute Onyx®) compared with biodegradable polymer drug-eluting stent (Biomatrix®, Biomatrix Flex®, Nobori®, Ultimaster®, Synergy ® and Orsiro®) in terms of patient-oriented composite outcome Non-inferiority of 5 mg compared to 10 mg dose of prasugrel maintenance in terms of major adverse cardiovascular events

This study is aimed to evaluate the effect of renal denervation to decreasing blood pressure and left ventricle remodeling progression in patients after acute coronary syndrome.

The purpose of this study is to compare the effectiveness and safety, at 24 months, of the TITAN2 stent to any bare-metal stent (BMS) in Cobalt-Chromium in a population presenting an indication for these stents among 40% of which present an acute coronary syndrome (ACS).

Research hypothesis: Is the treatment with renal denervation (RDN) early post ACS safe and effective and does it leads to improved cardiac function and attenuation of pathologic left ventricular remodelling? In a following study, the hypothesis will be tested in a larger ACS population with major adverse cardiovascular events (MACE) after ACS as the endpoint. Rationale for conducting this study: ACS i.e. ST-elevation myocardial infarction (STEMI) and non- ST-elevation myocardial infarction (non-STEMI) are the most important causes of morbidity and mortality in western societies. Hypertension is a major risk factor for development of ACS and heart failure but it also worsens the prognosis in patients after ACS. Our research highlights the combination therapy of PCI and RDN in an ACS patient population with simultaneous hypertension. Primary objective: The primary objective of this study is to establish safety and efficacy of combined treatment with PCI and renal denervation (RDN) in hypertensive patients with acute coronary syndromes (STEMI and non-STEMI ) having ventricular mass after 4 months as the primary variable. Endpoints: The primary end point is change in left ventricular mass (LVM) at 4 months evaluated by magnetic resonance imaging (MRI). Secondary endpoints:, blood pressure (office and 24-h ABPM), and left ventricular volumes and ejection fraction.

This protocol describes a study to compare intended trans-radial versus trans-femoral intervention and bivalirudin monotherapy versus current European standard of care consisting of unfractionated heparin (UFH) plus provisional use of glycoprotein IIb/IIIa inhibition via the use of one of the three available agents on the market (e.g. abciximab, tirofiban or eptifibatide) in patients (≥18 years) with ACS, that are intended for an invasive management strategy. This study will be conducted in compliance with Good Clinical Practices (GCP) including the Declaration of Helsinki and all applicable regulatory requirements.

Prospective, randomized, multi-center trial comparing the safety and efficacy in the prevention of net adverse clinical outcomes (NACE) of transfemoral vs. transradial approach for the treatment of patients with ST-elevation acute coronary syndrome (STEACS) undergoing primary angioplasty

Assess the role of a nicotine antagonist in helping patients presenting to hospital with acute coronary syndrome to stop smoking.

The purpose of this study is to compare the antinflammatory and endothelial progenitor cell (EPC) mobilizing effect of Ramipril and Telmisartan in patients presenting with acute coronary syndrome

This is a prospective observational study focused on monitoring the effects of various treatment options for acute coronary syndrome (ACS) patients by measuring serum neopterin levels. Serum neopterin is a marker for measuring macrophage activation. Prior studies have illustrated that there are elevated serum neopterin levels in ACS. Patients enrolled are those with ACS. Blood samples are drawn at presentation, and at 72 hours after admission, or at office visits and at 72 hours later. Neopterin levels are measured via a commercially available assay..

The McGill University Health Center (MUHC) Division of Cardiology, with funding from the Canadian Institute of Health Research, is performing this randomized controlled trial to determine which dual antiplatelet therapy (DAPT), ticagrelor + aspirin (T+A) or clopidogrel and aspirin (C+A), is the most effective and safest for our patients. While the PLATO trial reported that T+A was superior, the prespecified group of North American patients (about 1/10 of the total study sample) actually did better with C+A, although this difference was not statistically significant. When the FDA approved T, they also stated: "Lack of Robustness of PLATO Superiority with Failure in the US Makes a Confirmatory Study Mandatory." As no confirmatory study has been done, this TC4 study aims to fill that void. Study design: A cluster randomization design, so all patients will receive either T+A or C+A, depending on the month they arrive at the MUHC when they start their DAPT. We will follow patients through their electronic health records. The patients have no follow-up visits for this research project.
