Active clinical trials for "Acute Coronary Syndrome"

Patients with suspected acute coronary syndrome account for a tenth of all presentations to the Emergency Department and up to 40 per cent of unplanned hospital admissions. The majority of patients do not have a heart attack (myocardial infarction), and may be safely discharged from the Emergency Department. The investigators propose to evaluate whether the use of the HighSTEACS pathway in patients with suspected acute coronary syndrome reduces length of stay and allows more patients to be safely discharged from the Emergency Department. This pathways utilizes high-sensitivity cardiac troponin I testing and will rule out myocardial infarction if troponin concentrations are <5 ng/L on presentation, with further testing indicated at 3 hours only in those presenting early or with troponin concentrations between 5 ng/L and the 99th centile. In six secondary and tertiary centres across Scotland, the investigators will introduce the pathway as part of a stepped wedge cluster randomized controlled trial. Sequential hypothesis testing will evaluate the efficacy and safety of the pathway. The primary efficacy end-point will be length of stay from time of presentation until final hospital discharge and the primary safety end-point will be survival free from type 1 or 4b myocardial infarction or cardiac death from discharge to 30 days. The study population will consist of those patients with cardiac troponin concentrations within the normal reference range (<99th centile) at presentation.

Ticagrelor 90 mg twice daily treatment is recommended for 12 months in patients with acute coronary syndrome (ACS) and in patients undergoing coronary revascularization and conservative strategies. Recent data from the PEGASUS-TIMI 541 trial have shown that long-term treatment with ticagrelor reduced the risk of major cardiovascular adverse events (MACE) in stable ambulatory patients with a history of myocardial infarction. Based on these data, prolongation over 12 months of ticagrelor therapy could be indicated in selected patients; even if with such a prolongation some adverse effects on the treatment could be observed. In the PLATO2 trial, where median duration of exposure to the study drug was 277 days, the suspension of ticagrelor therapy was 7.4% in ticagrelor versus 6% in patients receiving clopidogrel ( P <0.001). Ticagrelor treatment interruption was mainly driven by non-serious adverse events occurring mainly shortly after randomization. For patients after the first year of treatment, the subsequent rate of interruption was low. These data demonstrate that adverse events considered "not serious" by traditional trial criteria may have an effect on quality of life and, therefore, can cause treatment interruption; The phenomenon emphasizes at the same time the importance of patient education and advice on timing and the nature of adverse effects in order to improve adherence. Patients in the real world may show a premature suspension rate of the drug even higher than in clinical trials. However, data from real-world patients is scarce.

Recent studies have shown that the systemic inflammation caused by periodontal disease (PD) can determine important changes in the coronary arteries, favoring atherosclerosis progression and development of acute coronary syndromes (ACS). The aim of ATHERODENT study is to assess the interrelation between PD, inflammation and progression of coronary atherosclerosis in patients with ACS. Material and methods: This case-control observational study will enroll 100 patients (group 1 - ACS and associated PD, and group 2 -ACS and no PD), in whom the following data will be collected: (1) demographic and clinical data, (2) cardiovascular risk factors, (3) full characterization of PD markers, (4) systemic inflammatory biomarkers, (5) imaging biomarkers derived from transthoracic echocardiography, computed tomography, coronary angiography, optical coherence tomography and intravascular ultrasound, and (6) assessment of the presence of specific oral bacteria in samples of coronary plaques collected by coronary atherectomy, which will be performed during percutaneous revascularization interventions, when indicated in selected cases, in the atherectomy sub-study. The follow-up will be performed at 1, 3, 6, 12, 15, 18 and 24 months. The primary endpoint of the study will be represented by the rate of major adverse cardiovascular events (MACE rates) in PD vs non-PD patients and in correlation with: (1) the level of systemic inflammation triggered by PD and/or by ACS at baseline; (2) the vulnerability degree of atheromatous plaques in the coronary tree (culprit and non-culprit lesions); and (3) the presence and burden of oral bacteria in atheromatous plaques. Secondary endpoints will be represented by: (1) the rate of progression of vulnerability degree of non-culprit coronary plaques; (2) the rate of progression of atheromatous burden and calcium scoring of the coronary tree; and (3) the rate of occurrence of left ventricular remodeling and postinfarction heart failure.

When doctors and nurses use accepted guidelines for quickly treating patients who come to the emergency department (ED) with a possible heart attack, patients do better. Research shows that there are racial-identity- and ethnicity-based differences in the symptoms these patients have, when and why they seek care, the treatments they receive, and how well they fare afterwards. There is also Canadian evidence that there may be racial-identity-based disparities in the care some patients receive, and it has been suggested that health professionals may unconsciously treat patients of different racial identities differently. But it is not known if there is racial-identity variation in the care given to Canadian patients with heart attack symptoms in the critical first hours after coming to an ED, or in their experiences of this care. The investigators collected information from the health records of patients who come to EDs with symptoms of heart attack. The investigators recorded events and times such as what provisional diagnosis was assigned to the patient, how often they received pain medication, how long until certain tests were performed and what treatments were offered. The investigators also collected information about things that might affect delivery of care, e.g., the number of doctors and nurses who were on duty. Participants also completed a short questionnaire about their reasons for coming to the hospital, how long they waited before coming and why, and what their experience in the ED was like. The investigators reviewed this information to see if there are racial-identity-based differences in the care received by patients with heart attack symptoms. The findings could identify important disparities, which could in turn inform future projects to correct these disparities, for example, education of health professionals about ethnic differences in ideas of health and illness.

The aim of REHAB trial is to investigate the impact of early mobilization after AMI in reducing left ventricular remodeling, as assessed by cardiac magnetic resonance imaging. At the same time, the study aims to demonstrate the contribution of early mobilization to reduction of: systemic inflammation in the immediate post infarction phase, complication rates and mortality, in patients who had suffered a recent AMI, for a 1 year follow-up period.

The objective of the study is to assess the performance characteristics of Apo J-Glyc as a novel biomarker for the early detection of myocardial ischaemia in patients with suspected acute coronary syndromes.

The global burden and threat of non-communicable diseases (NCDs) have become a major health challenge that undermines social and economic development throughout the world. Cardiovascular disease including acute coronary syndromes (ACS) currently accounts for 17.9 million deaths a year. Low and middle-income countries such as those in sub-Saharan Africa (SSA) have undergone a rapid epidemiological transition over the last few decades and now have a burden of disease increasingly dominated by NCDs. The global burden of disease report for 2017 revealed a 71.4% increase in cardiovascular disease in SSA, predicting a large increase in mortality. Unfortunately, reliable population-level data regarding the incidence, prevalence and demographics of ACS in SSA are limited. The investigators propose to set up and conduct a multi-centre, prospective, observational registry to describe the demographics, clinical characteristics, presentation, management and outcomes of patients admitted with ACS in Cape Town and the Garden Route Health District, Western Cape Province, South Africa. The registry is designed to shed insight on the current burden and impact of atherosclerotic cardiovascular disease in the Western Cape.

This study is to evaluate the incidence rate of Major Adverse CardioCerebrovascular Events(MACCE) in Patients with Acute Coronary Syndrome or Cerebral Infarction Who Received DAPT for the secondary prevention and Esomezol Cap for the prevention of gastrointestinal bleeding.

Asprosin, a recently discovered glucogenic adipokine, is mainly synthesized by white adipose tissue and released during fasting. Appetite, glucose metabolism, insulin resistance, cell apoptosis, etc. asprosin is associated with diseases such as diabetes, obesity, polycystic ovary syndrome, and cardiovascular diseases. Periodontal tissue may act as a source of endocrine-like inflammatory mediators (such as TNF-α, IL-6 and IL-1) that are important in periodontal inflammation and can affect glucose and lipid metabolism. Production of TNF-α and IL-6 in adipose tissues strengthens the relationship between cardiovascular diseases and periodontitis. Investigators postulated that asprosin may be a candidate for explaining the triangular relationship between cardiovascular and periodontal disease.
