Filter by:The primary objective of this study is to assess the accuracy in terms of sensitivity, specificity, negative and positive predicted values of the DL-based algorithm with respect to correct identification of the plaque and associated vulnerability grade.
For patients with ACS undergoing PCI, intensive lipid-lowering including PCSK9 monoclonal antibody should be started as soon as possible, that is, lower LDL-C level should be achieved as soon as possible. Compared with conventional lipid-lowering regimen, it is expected that the occurrence of major adverse cardiovascular events can still be reduced after drug discontinuation. Therefore, the optimization strategy of "for patients with ACS undergoing PCI, intensive lipid-lowering with PCSK9 monoclonal antibody can be started as soon as possible" is proposed.
Magnetocardiography (MCG) is a promising noninvasive and accurate method for detecting myocardial infarction. Although progress has been made in this area, there is a lack of studies using up-to-date examination instruments for the calibration of MCG analysis. This is a prospective single-center study aiming to build accurate analytical models of MCG to detect myocardial infarction. Myocardial infarction are diagnosed by electrocardiogram, biomarkers (high-sensitivity cardiac troponin, etc), or non-invasive imaging (cardiac magnetic resonance or single-photon-emission tomography). Myocardial infarction is also quantified by cardiac magnetic resonance or single-photon-emission tomography. Healthy volunteers and chest pain patients who will receive electrocardiogram, biomarkers (high-sensitivity cardiac troponin, etc), or non-invasive imaging (cardiac magnetic resonance or single-photon-emission tomography) examination will be enrolled in this study.
This study aims to investigate the association between H.Pylori and ACS .
The PROTEUS study is a randomized, cross-over, open-label, pharmacodynamic trial designed to compare the antiplatelet effect of reduced maintenance doses of prasugrel and ticagrelor in stable patients who recently had non-ST-elevation acute coronary syndrome (non-ST-elevation myocardial infarction or unstable angina).
The aim of the study is to acess the association between admission serum uric acid level and in_hospital outcomes in patients with acute coronary syndromes
Magnetocardiography (MCG) is a non-invasive and accurate method of detecting myocardial ischemia. However, the previous MCG is limited in clinical practice due to its high working conditions and limited sensitivity. The next-generation MCG based on optical pumped magnetometer (OPM) has the advantages of high sensitivity, high reliability, high usability and low cost, which makes it suitable for most medical scenarios. Thus, this prospective single-center study aimed to use OPM MCG to explore its diagnostic efficacy and predictive value for myocardial ischemia. Participants who will receive coronary angiography examinations will be enrolled in this study. Participants enrolled in the study will also have a 1, 3, 6, 12, 24, 36, and 48-month follow-up for analysis of adverse cardiac events.
Limited data have been published on the management and outcome of patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) that involves the left main (LM) coronary artery. Little is known about different strategies and techniques of percutaneous revascularization and long-term outcomes of these patients. Beside scarcity of data, most studies represent outmoded experience not reflecting contemporary advances in stent technologies, with the introduction of newer generation thinner strut drug eluting stents (DES), bioresorbable polymers, and faster re-endothelization properties promoting vascular healing and endothelial repair. These advances have significantly reduced the rate of ischemic (especially thrombotic) complications in different cohorts. Whether these advances would alter the outcome of PCI that involves the LM in patients with ACS is yet to be explored. II. Objective 1. To explore real-world PCI strategies and techniques in patients with unprotected LM coronary disease presenting with ACS 2. To explore short- and long-term outcomes of patients of ACS with LM intervention III. Study endpoints Primary endpoint Major adverse cardiovascular events (MACE) at one year; a composite of all-cause mortality, non-fatal myocardial infarction (MI), or unplanned revascularization* *With further extended yearly follow-up to 5 years Secondary endpoints 1) All-cause death at one year* 2) Non-fatal MI at one year* 3) Any unplanned revascularization at one year* 4) Target vessel revascularization (TVR) at one year* 5) Academic Research Consortium (ARC) definite/probable stent thrombosis at one year* 6) Bleeding Academic Research Consortium (BARC) type 3 or 5 bleeding at one year* 7) Contrast induced nephropathy (CIN) defined as serum creatinine rise >25% or absolute increase >0.5 mg/dL within 72 hours after index PCI 8) Echocardiographic left ventricular ejection fraction (LVEF)% [Time Frame: from 6 to 12 months after index PCI]* 9) Angiographic (re)stenosis of the LM [Time Frame: from 6 to 12 months after index PCI] (Optional)
This projects studies the role of tai chi exercise and wearable fitness trackers to promote physical activity in acute coronary syndrome (ACS) survivors.
Chest pain is a frequent reason of consultation in emergency department. Emergency physician have to identify patients at high risk of Acute Coronary Syndrome from those presenting a lower risk.
