Filter by:The objective of this study is to assess the safety and efficacy of the DREAMS 3G in the treatment of subjects with up to two de novo lesions in native coronary arteries compared to a contemporary drug eluting stent (DES).
thoracic pain is one of the most frequent reasons for consulting the emergency room. Chest pain can be a sign of different pathologies with a wide range of severity, from life-threatening aortic dissection or myocardial infarction to chest pain during an anxiety attack. Efficient triage of patients is therefore a crucial issue for emergency physicians in order not to ignore an acute coronary event requiring early and specific management. The investigators seek to evaluate whether a diagnostic strategy based on a thoracic CT scan to rule out coronary calcifications and a single troponin assay can exclude an acute coronary event with sufficient accuracy compared to usual management.
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).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.

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.
Coronary heart disease (CHD) is the leading cause of mortality worldwide. Every year, millions of people suffer its most adverse manifestation, an acute myocardial infraction (AMI). The majority of these patients present at least one of the standard modifiable risk factors (SMuRFs). These include smoking, hypertension, dyslipidemia, and diabetes mellitus (DM). However, emerging scientific evidence recognizes a clinically significant proportion of patients presenting with life-threatening AMI without any SMuRF (SMuRF-less patients). This proportion of patients with ACS without SMuRF appears to be increasing during the last two decades and has recently been reported as high as 20% (of total AMIs). To date, there are no scientific data capable of highlighting specific risk factors-biomarkers responsible for the development of AMIs SMuRF-less patients. Therefore, two groups of patients with AMI (with SMuRFs vs SMuRF-less) will be compared regarding their clinical, laboratory and imaging (echocardiographic and angiographic) profile, and possible predictive factors leading to SMuRF-less AMI will be evaluated. On the basis of the above, the aim is to prospectively analyze a cohort of well-characterized patients with AMI. The rationale of the study is to investigate potential correlations between metabolic profile of patients and SMuRF-less AMI. This could lead to the development of predictive risk stratification algorithms for patients without SMuRFs and coronary artery disease.
This is a prospective four-site cohort study, which will accrue adults with symptoms concerning for acute coronary syndrome over a period of 12 months. After application of inclusion and exclusion criteria, Physicians will complete HEART Pathway and EDACS risk assessments on eligible participants. Major adverse cardiac events as defined by our study will be assessed at 30 days using electronic health record, telephone contact, and national death and health events search. Outcomes for all patients will then be matched against the existing pathway of care for acute chest pain that is being used currently to compare diagnostic accuracy of both scores to diagnose low risk chest pain in this population. The objective of this study is to compare the test performance of the HEART and EDACS pathway in a large cohort of patients presenting to the Emergency department with chest pain in the United Arab Emirates and to determine if either accelerated diagnostic pathway can achieve a negative predictive value of ≥99% for 30-day MACE as well as to externally validate EDACS-ADP and the HEART pathway in the UAE population and gain further insight into the applicability of these decision-making aids in different clinical settings in order to assess which score is best suitable for the UAE population. Our third objective is to compare the effectiveness of both scores to the existing framework for chest pain work up in each hospital and have the opportunity to unify Emergency Departments in their chest pain pathways in the UAE. The investigators will be testing the null hypothesis that there is no difference in using the EDACS-ADP to safely classify patients to low-risk category and early discharge from the ED versus the HEART pathway.
Coronary angiography is a key examination in the management of many patients hospitalized in intensive care units. The most frequent indication remains the performance of a gesture of unblocking of part of the coronary network in the context of an acute coronary syndrome (ACS) complicated by cardiogenic shock (CS) and/or cardiac arrest. cardio-respiratory (ACR). However, there are other indications in intensive care, in particular for diagnostic purposes. Given the lack of harmlessness of this procedure in itself and the consequences of intra-hospital transport outside intensive care units for patients who are sometimes very unstable, the risk-benefit balance before performing a coronary angiography requires always be properly assessed by the resuscitating physician.
Acute coronary syndromes (ACS) represent a major contributor to mortality, morbidity, and healthcare costs. Effective therapies are widely available; however, adherence is low. This contributes to worse patient outcomes and increased risk of morbidity and mortality. The once-daily polypill leverages a population-based strategy that has previously demonstrated efficacy in improving adherence and access to therapy in low-resource settings, making it an innovative approach for improving post-ACS care. This study aims to investigate the utility of a polypill-based strategy for patients with ACS with drug eluting stent (DES) placement. The polypill will consist of a high-intensity statin (rosuvastatin 40 mg daily), aspirin 81 mg daily, and either clopidogrel 75 mg or prasugrel 10 mg daily.
This study aims to: 1. Assess the incidence of hemostasis failure after manual compression of trans-femoral arterial sheath post percutaneous coronary intervention. 2. Assess the predictors of time to hemostasis achieved by manual compression for trans-femoral arterial sheath post percutaneous coronary intervention. 3. Assess the association between time to hemostasis and the incidence of vascular access complications after manual compression for trans-femoral arterial sheath removal post percutaneous coronary intervention. 4. Assess the association between failed hemostasis and the incidence of vascular access complications after manual compression for trans-femoral arterial sheath removal post percutaneous coronary intervention.
Several clinical and preclinical studies have focused interest on lipoprotein(a) [Lp(a)], showing a direct and independent relationship of its circulating levels with the progression of atherosclerosis and its clinical manifestations. However, to date, Lp(a) represents an underestimated predictor of CV risk, especially in higher-risk populations, such as patients with strong CV familiarity and recurrent and/or early-onset CV events. The key point of the project will be the evaluation of the role of Lp(a) in the development of atherosclerotic disease and, specifically, acute coronary syndrome.
