Filter by:The China ST-elevation myocardial infarction (STEMI) Care Project (CSCAP) aims to improve the reperfusion treatment rate and shorten the total duration of myocardial ischemia by establishing a regional STEMI treatment network covering the whole-city region, whole-city population, and whole-disease process step by step. The CSCAP is a prospective, multicenter registry involving three phases. A total of 18 provinces, 4 municipalities, and 2 autonomous regions in China were included. Patients with STEMI who met with the third acute myocardial infarction definition and the Chinese STEMI diagnosis and treatment guidelines were enrolled and the estimated number is over 50,000. Phase 1 (CSCAP-1) focused on the in-hospital process optimization of primary percutaneous coronary intervention (PPCI) hospitals. Phase 2 (CSCAP-2) focused on the PPCI hospital-based regional STEMI transfer network, including emergency medical services and non-PPCI hospitals. Phase 3 (CSCAP-3) focused on the whole-city STEMI care network construction by promoting chest pain center accreditation. Systematic data collection, assessment of quality of care, and subsequent improvement were implemented throughout the project to continuously improve the quality of care for patients with STEMI. CSCAP is the first project that focused on establishing a regional STEMI emergency care network in China to help understand the condition of STEMI care in China extensively. Moreover, its objective was to optimize the quality of STEMI care through in-hospital process optimization (2012-2013), PPCI hospital-based regional STEMI transfer network construction (2015-2018), and construction of the whole-city STEMI care network step by step (2018-2021). However, hospitals were not randomly selected in CSCAP, which might be because of the lack of representatives to some degree. Alternatively, it focused on providing a tailored quality-of-care improvement plan based on the conditions of different regions.
The project is focussed on evaluating the impact of using a female-specific threshold in the diagnosis of myocardial infarction. This female threshold is lower than the overall hs-cTn threshold currently in use. The investigators hypothesize that this change in process, applied at the hospital level, will lead to better assessment, treatment and outcomes of women presenting to the emergency department with chest pain that is cardiac in nature.
Anti-platelet therapy is a key point of acute myocardial infarction (AMI) treatment. Nowadays, dual anti-platelet therapy based on aspirin and ADP-P2Y12 receptor inhibitor is the preferred treatment before primary percutaneous coronary intervention (PPCI). Restricted by pharmacokinetic and pharmacodynamic characteristics, ADP-P2Y12 receptor inhibitors cannot take effect immediately after oral administration. However, platelet glycoprotein Ⅱb / Ⅲa inhibitors take effect faster. Previous clinical trials indicated that combination of full dose of glycoprotein Ⅱb / Ⅲa inhibitor and dual anti-platelet therapy reduced AMI related ischemia events but increased bleeding events significantly. The high dose of glycoprotein Ⅱb / Ⅲa inhibitor may be the key factor contributing to the increased bleeding events. Therefore, this study aims to evaluate the effectiveness and security of triple anti-platelet therapy based on a small dose of glycoprotein Ⅱb / Ⅲa inhibitor, aspirin and ADP-P2Y12 receptor inhibitor in AMI patients receiving PPCI.
To determine the therapeutic effects of Tongxinluo Capsules as compared with placebo in the treatment of patients with acute ST-elevation myocardial infarction (STEMI): (1) Clinical efficacy and safety at 30 days: the incidence of composite endpoints comprising major adverse cardiovascular and cerebrovascular events (MACCE, including cardiovascular death, myocardial re-infarction, emergency coronary revascularization and cerebral stroke), severe complications (including cardiogenic shock, heart failure, mechanical complications and malignant arrhythmias), and major bleeding (BARC grade III and V); (2) Clinical efficacy and safety at 1 year: the incidence of composite endpoints comprising MACCE, hospitalization due to heart failure, in-stent thrombosis, and major bleeding (BARC grade III and V), as well as all-cause mortality; (3) the effects in promoting myocardial reperfusion, reducing incidence of myocardial no-reflow, protecting ischemic myocardium, minimizing infarction size, and improving left ventricular systolic function.
In a prospective, randomized clinical trial the iPOST2 trial will determine whether ischemic postconditioning reduces reperfusion injury and this will translate into improved clinical outcome of heart failure and death for STEMI patients who present with TIMI0-1 undergoing primary PCI
To determine whether long-term treatment with oral betablocker therapy after myocardial infarction in patient with no heart failure reduces the composite outcome of recurrent MI, all-cause mortality, revascularisation with percutaneous coronary intervention or coronary artery bypass graft, ischemic stroke, incident heart failure, malignant ventricular arrhythmia or resuscitated cardiac arrest.
The purpose of this registry is to depict the myocardial tissue characteristics in STEMI patients by CMR and other cardiac imaging modalities and to assess the prognostic value of imaging-derived indices. Information will be collected prospectively in about 1000 STEMI patients in 10 sites. Subjects will be followed for up to 5 years.
Left ventricular thrombus is a common complication subsequent to ST-segment elevation myocardial infarction (STEMI) that related to increased embolic events. This study aims to assess the efficacy and safety outcomes of Rivaroxaban on the treatment of post-STEMI left ventricular thrombus.
This study is to validate 1-hour and 3-hours diagnostic strategy using Architect high-sensitivity cardiac troponin I (hs-cTnI) in Chinese patients with suspected Non-ST-elevation Myocardial Infarction (NSTEMI). The accuracy of 1-hour and 3-hours algorithm of NSTEMI using hs-cTnI assays will be evaluated in China emergency patients. This trail is going to determine the optimal diagnostic cut-off value of NSTEMI in Chinese population according to 24-hour or longer clinical diagnosis of MI in routine way.
ST-elevation myocardial infarction (STEMI) is mostly caused by the rupture or the erosion of a vulnerable atherosclerotic plaque, initiating with intraluminal thrombosis and resulting in total occlusion of the coronary artery. Thrombus formation is a complex and dynamic process involving flow, blood cells and several plasma proteins, and it has not been clearly elucidated. To define - through proteomic approach - the composition of occluding thrombus and its time changes in patients with STEMI, trying to identify novel biomarkers of coronary thrombosis.
