Active clinical trials for "Acute Coronary Syndrome"

Acute coronary syndrome (ACS) is any group of clinical symptoms compatible with acute myocardial ischemia and includes unstable angina (UA), non-ST-segment elevation myocardial infarction (NSTEMI), and ST-segment elevation myocardial infarction (STEMI). (1). In Egypt, the overall prevalence of coronary heart disease (CHD) is 8.3 % (2). In addition, CHD in Egypt is the principal cause of death, responsible for 21.73% of total mortality (2). Beta-blockers have shown to reduce the short-term risk of a reinfarction and the long-term risk of all-cause mortality and cardiovascular mortality (3). Beta blockers are used within 24 hours of ACS and given as long-term therapy after discharge (4). The Most frequently used drug in Egypt is bisoprolol. In patients with myocardial infarction undergoing primary percutaneous coronary intervention, early intravenous betablocker before reperfusion reduced infarct size and increased left ventricular ejection fraction (4). Despite the established benefits of beta blockers in ACS (acute coronary syndrome patients), they showed interindividual variability in patient's' blood pressure and heart rate (5). pharmacokinetic variability was found in bisoprolol response especially in elderly patients (6). Bisoprolol is eliminated in equal parts by hepatic metabolism by CYP2D6 and CYP3A4 enzymes and by the kidney(7). A possible cause for this variability may be due to CYP450 genetic polymorphism. The CYP450 activity ranges considerably within a population and includes ultrarapid metabolizers (UMs), extensive metabolizers (EMs), intermediate metabolizers (IMs) and poor metabolizers (PMs) (8).The proposed research in this application will investigate the correlation between CYP2D6 and CYP3A4 polymorphism and pharmacokinetics of bisoprolol and will investigate the impact of the Genes' polymorphism on the clinical effect of bisoprolol in patients with acute coronary syndrome.

In patients with myocardial infarction undergoing primary percutaneous coronary intervention, early intravenous betablocker before reperfusion reduced infarct size and increased left ventricular ejection fraction (4).drug interactions are common in ACS patients due to polypharmacy and comorbidities.(5) there are limited studies investigating drug interactions with bisoprolol in acute coronary syndrome patients. The proposed research in this application will investigate potential drug interactions with bisoprolol in patients with acute coronary syndrome.

Patients with troponin-negative acute coronary syndrome (ACS) are not routinely pre-treated with P2Y12 inhibitors and the rate of high on-treatment platelet reactivity (HPR) remains elevated after a loading dose of ticagrelor at the time of percutaneous coronary intervention (PCI). This suggests that faster platelet inhibition with crushed ticagrelor , eptifibatide , or cangrelor is needed to reduce HPR and periprocedural myocardial infarction and injury (PMI). The present study compared the effects of crushed ticagrelor vs. eptifibatide bolus + clopidogrel in troponin-negative ACS patients undergoing PCI.

This is a randomized controlled pilot trial in approximately 50 acute coronary syndrome patients to determine if a 12 week, telephone-delivered, combined positive psychology-motivational interviewing intervention is feasible and more effective than a motivational interviewing health education program at improving health behaviors and other outcomes. The investigators hypothesize that the intervention will be associated with better mental and physical health outcomes and better health behavior adherence compared to the motivational interviewing health education program.

Primary Objective: To compare the efficacy of alirocumab (Praluent®) with standard of care (SoC) on coronary atheroma progression (percent change in normalized total atheroma volume [TAV]) after 9 months of treatment in participants who had acute coronary syndrome (ACS) within 4 weeks prior to randomization, with hypercholesterolemia treated with statin. Secondary Objectives: To compare the efficacy of alirocumab (Praluent®) with SoC on secondary endpoints including absolute change in percent atheroma volume and normalized TAV after 9 months of treatment. To evaluate the efficacy of alirocumab (Praluent®) on low-density lipoprotein cholesterol (LDL-C), apolipoprotein B, triglycerides, non-high-density lipoprotein cholesterol and lipoprotein (a) after 9 months treatment. To evaluate the safety of alirocumab (Praluent®) including the occurrence of cardiovascular events (coronary heart disease death, non-fatal myocardial infarction, fatal and non-fatal ischemic stroke, unstable angina requiring hospitalization) throughout the study.

Investigators aimed to test the beneficial effect of tirofiban, a GPIIb/IIIa antagonist, for Non-ST-Elevation Acute Coronary Syndrome Patients who has high resistance to clopidogrel.

PCI is considered as the reperfusion strategy of choice for patients with acute STEMI. Data from RCTs and meta-analyses demonstrate a consistent and strong signal towards a significant reduction in MACE among patients with STEMI undergoing primary PCI with newer generation stents with enhanced biocompatibility. The present trial aims at filling the current gap of evidence by providing randomized data to establish the superior clinical outcome with an ultrathin strut third-generation DES with biodegradable polymer designed to improve vascular healing in patients with STEMI undergoing primary PCI, compared to the current state-of-the art second-generation DES with permanent polymer.

The objective of the RAPID GENE study is to evaluate the feasibility, efficacy and safety of a pharmacogenomic approach to anti-platelet therapy following coronary artery stenting using a CYP2C19*2 point-of-care genetic test.

In full responders to clopidogrel scheduled to undergo PCI for NSTEACS, the use of abciximab bolus only plus 600 mg clopidogrel loading dose will result in a non-inferior inhibition of platelet aggregation after 4 hours as measured by LTA (20micromol ADP) when compared with abciximab plus infusion and 300 mg clopidogrel loading dose.

Primary Objective: To demonstrate the superior efficacy (composite of all-cause death + Myocardial Infarction (MI)) of Otamixaban to Unfractionated Heparin (UFH) + Eptifibatide Secondary Objectives: To demonstrate the superior efficacy (composite of all-cause death + MI + any stroke) of Otamixaban as compared to UFH + Eptifibatide To document the effect of Otamixaban on rehospitalization or prolongation of hospitalization due to a new episode of myocardial ischemia/myocardial infarction as compared to UFH + eptifibatide To document the effect on mortality (all cause death) of Otamixaban as compared to UFH + eptifibatide To document the safety of Otamixaban as compared to UFH + eptifibatide To document the effect of Otamixaban on thrombotic procedural complications during the index Percutaneous Coronary Intervention (PCI) as compared to UFH + eptifibatide
