Filter by: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.
the study aims to 1. identify the effect of addiction on TIMI flow in patients presented with acute coronary syndrome. 2. identify the effect of addiction on outcomes of medical treatment of patients presenting with acute coronary syndrome. 3. identify the relation between addiction and LV function. 4. detect the effect of duration of addiction on myocardial infarction lesion and outcomes of pci.
Patients who suffered from acute coronary syndrome (ACS) are usually treated with a long-term dual antiplatelet therapy (DAPT) to reduce stent thrombosis and recurrent ischemic event. Nonetheless, recent important data have demonstrated the efficacy of a short term DAPT and an early single antiplatelet therapy in high bleeding and ischemic risk patients. The bleeding risk is associated with a significant mortality. This risk is especially high in patients treated with potent P2Y12 inhibitors like ticagrelor or prasugrel after an ACS. As a result of the abounding data regarding the safety of an early single antiplatelet therapy with high potency antiplatelet therapy (ticagrelor or prasugrel), it is likely that such strategy will soon be implemented in the guidelines. The benefits of these high-potency P2Y12 inhibitors over clopidogrel mostly occur in patients with genetic polymorphisms of CYP2Y12 associated with a loss of function in clopidogrel metabolism. Furthermore, the anti-ischemic benefit of potent P2Y12 inhibitors over clopidogrel occurs early, while excess bleeding events often arise during chronic treatment. Our hypothesis is that a systematic and rapid genetic screening of CYP2C90 *2 or *17 polymorphism to guide an early single therapy with low potency antiplatelet (aspirin or clopidogrel) could lead to less bleeding events with a consistent efficacy towards cardiac events compared with high potency antiplatelet therapies (prasugrel or ticagrelor) in high bleeding risk patients treated for ACS.
