Filter by:In this study, the investigates try to confirm our hypothesis that low dose ticagrelor(60mg) had similar anti-platelets function compared with the standard dose ticagrelor in senior （no less than 75 years old)acute coronary syndrome patients . Totally 40 senior ACS patients will be divided into 2 groups randomly one month after PCI . Group 1 will be treated with ticagrelor 90mg and aspirin 100mg after PCI for 12 months as the standard group; Group 2 will be treated with ticagrelor 60mg plus aspirin 100 mg for 11 months after one month standard DAPT treatment. The platelets function will be tested in VASP and TEG methods 2 months after PCI as the primary endpoints.The clinical events will be observed 12 months after PCI.
This study aims to investigate the incidence and characteristics of cognitive Impairment(CI) in the elderly patients with acute coronary syndrome (ACS), and to determine whether CI are predictive of the prognosis of major adverse cardiovascular events (MACE) and mortality.
Patients with Acute Coronary Syndrome associated with de novo atrial fibrillation are randomized to benefit from either a conventional therapy associating dual antiplatelet therapy (DAPT) and anticoagulant or DAPT and an implantable monitoring device with a follow-up by telecardiology
This study is to evaluate the safety and efficacy of 60mg ticagrelor plus 100mg Aspirin to prevent major adverse cardiovascular and cerebrovascular events in one years after drug-eluting stents implantation for Chinese ACS patients compared with 90mg ticagrelor plus 100mg Aspirin
This is a prospective, observational, multicenter study that enroll consecutive and all-comers patients hospitalized with a diagnosis of Acute Coronary Syndrome (ACS) at admission.
The present study is aimed to compare the safety and efficacy of Ticagrelor with low-dose Aspirin versus standard dual anti-platelet therapy (DAPT) in patients with acute coronary syndrome (ACS) at high risk for ischemic events after percutaneous coronary intervention (PCI) and stent implantation.
The BRAVADO Registry pretends to identify stratification, diagnosis, total atherosclerotic burden and treatment approaches in oncologic patients with Acute Coronary Syndrome (ACS) and identify strategies to improve health care quality
In this project the investigator's plan to collect blood during a patient's routine angiogram procedure which they will have due to having suffered a heart attack. Data from the patients' routine procedures for this condition, including but not exclusively, ECG, Echocardiogram, MRI scans, will be collected. The aim of the research project is to analyse the blood samples and identify novel biomarkers and clinical parameters associated with acute coronary syndromes. The investigator's will particularly focus on markers of inflammation and micro-organism activity. The investigator's hope that this will help to gain more knowledge about what causes heart disease and how various conditions can be treated more efficiently. The investigator's will follow-up and collect further research data via a questionnaire at the routine 6 weeks and 6 months follow-up appointment after the angiogram procedure. Participants will also be telephoned at one-year post procedure, to update any events and medication status and data will thereafter be collected form data held by the hospital without having to contact the participant. Remaining blood samples will be stored securely for further analysis into blood and other markers.
The present study aims to compare a planned angiographic control (PAC) follow-up strategy vs. conservative management for patients treated with drug-eluting stents on unprotected left main artery in a prospective, randomized setting. PAC will be performed by coronary computed tomography (CCT), to avoid the limitations of the invasive coronary angiography which is usually employed to perform PAC. The superiority of a PAC-based approach will be tested on a hard clinical end-point such as the incidence of major adverse cardiovascular events. The investigators will also assess the performance of CCT as a tool to perform PAC.
Background and rationale: Evaluating patients with acute chest pain, elevated high-sensitive cardiac troponin (hs-cTn) levels and non-diagnostic electrocardiogram (ECG), i.e. suspected non-ST elevation myocardial infarction (MI), is a daily challenge. Although contemporary hs-cTn assay-based algorithms have greatly facilitated clinical decision-making, still one-quarter of patients is categorized as 'observe' group and in whom a diagnosis initially remains unknown. Although routinely treated as acute (MI) with referral to invasive coronary angiography (ICA), up to one-third does not have obstructive coronary artery disease (CAD). Follow-up cardiac magnetic resonance imaging (CMR) has been shown to be a very useful diagnostic tool in this setting but is not part of routine clinical care in every patient. Objectives: To investigate in patients with suspected non-ST elevation MI meeting the 'observe' criteria and who are scheduled for ICA: 1) the prevalence of coronary artery disease as well as non-coronary artery disease related and extra-cardiac diseases by adding CMR early in the diagnostic pathway, and 2) the number of major adverse cardiac events (MACE) and a composite of MACE and major (non-cardiac) adverse events after 30 days and one year. These objectives allow an accurate estimate of the number of potentially avoidable ICA in the future and whether early CMR could be a safe gatekeeper for inappropriate ICA. Study population and design: In this prospective, observational two-center study in The Netherlands (MUMC+ and VieCuri Medical Center), 87 consecutive patients with acute chest pain, non-diagnostic ECG and hs-cTn levels meeting the observe criteria and scheduled for ICA, will be investigated. Patients will undergo a comprehensive CMR examination prior to ICA and will be followed-up at one month and one year. After completion of follow-up, an independent clinical diagnosis committee will adjudicate a final diagnosis: at discharge and after one year. The final diagnosis at discharge will be adjudicated twice: once with and once without considering the results of CMR. For the diagnosis at one-year, all clinical variables and CMR results will be considered. MACE and complications will be scored after 30 days and one year. Main study parameters/endpoints: The primary endpoint is the prevalence of coronary artery disease as well as non-coronary artery disease related and extra-cardiac diseases. The secondary (safety) endpoint is the number of major adverse cardiac events (MACE) and a composite of MACE and major (non-cardiac) adverse events after 30 days and one year. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: CMR is an accepted and safe imaging modality in patients with (suspected) non-ST-elevation myocardial infarction.
