Filter by:The aim of the study is to investigate the association between the use of β blockers and mortality among hospital survivors of acute myocardial infarction without heart failure.
The Tako-Tsubo Cardiomyopathy (TTC) and the Cardiac Syndrome X (CSX) are respectively acute and chronic heart diseases, which mimic myocardial infarction and stable angina pectoris without alterations of large coronary vessels. The causes and the most appropriate and best treatment for these diseases have not been yet clarified, but there are indications, that mental and psychosocial aspects may also contribute to these two diseases. So far, there is no study, which has comprehensively evaluated the interactions between mind and heart in these two conditions. The purpose of this study is to search for possible differences in mental activity, response to stressful events and function of specific areas of the brain deeply involved in relation between mind and heart. 45 subjects will be recruited and divided equally into: patients with CSX, patients with TTC (at least 6 months ago) and patients with previous acute myocardial infarction (at least 6 months ago). All participants will undergo a clinical interview and several questionnaires that assess various mental functions, the stress response and the quality of life. In addition, in a separate visit the participants will undergo a Magnetic Resonance Imaging without contrast medium that helps to assess function of specific areas of the brain.
This study is a phase 2, multicenter, double-blind, randomized, placebo controlled, parallel-group study to investigate the renal safety and tolerability of multiple dose intravenous (IV) administration of CSL112 compared with placebo in subjects with moderate renal impairment (RI) and acute myocardial infarction (AMI).
This study aims to establish a registry and surveillance system for acute myocardial infarction (AMI) patients in Xinjiang, focusing on collecting comprehensive information including basic patient demographics, patient characteristics, diagnostic methods, treatment programs, and hospitalization outcomes such as mortality, treatment complications, hospitalization costs, and follow-up events (death, major adverse cardiac events). The goal is to identify and propose effective prevention strategies to reduce the incidence of AMI, optimize the management and outcomes of AMI patients by implementing guideline recommendations in clinical practice, and conduct analyses to develop effective treatment strategies and predictive models for clinical outcomes. This focus on Xinjiang aims to provide a comprehensive understanding of AMI within this specific geographic and demographic context, ultimately contributing to improved prevention, treatment, and management of AMI patients.
The aim of the study is to compare clinical outcomes following fractional flow reserve (FFR)-guided versus angiography only guided strategy in treatment of non-infarction related artery (non-IRA) stenosis in patients with acute myocardial infarction (AMI) with multivessel disease Prospective, open-label, randomized, multicenter trial to test the clinical outcomes following FFR-guided or angiography-guided strategy in treatment of non-IRA stenosis in patients with acute AMI with multivessel disease.
Danlou tablets are Chinese patent medicine which has been approved in China for the treatment of ischemic heart disease, but the evidence supporting its efficacy on cardiac remodeling remains unclear. This pilot study was designed to determine whether Danlou tablets reduced adverse left ventricular (LV) remodeling in patients with acute myocardial infarction (MI). Patients following acute MI were enrolled and randomly allocated to Danlou tablets (4.5 g q.d. for 90 days) or placebo, superimposed on standard medications for the treatment of MI. Major end points were changes in LV volumes and ejection fractions as evaluated by serial echocardiography in addition to clinical outcomes were also determined.
A multicentric controlled phase I / IIb study evaluating the safety and the efficacy of in vitro expanded peripheral blood CD34+ stem cells output by the StemXpand® Automated Process, and injected in patients with an acute myocardial infarction and a LVEF remaining below 50% versus standard of care.
The current prospective, randomized, controlled MonAMI trial aims to systematically examine the effects of morphine on the platelet inhibitory effects of the orally administered platelet inhibitor ticagrelor in patients with acute myocardial infarction. In addition, the potential positive or negative effects of MCP in combination with morphine on platelet inhibition will be studied.
The purpose of this study was to evaluate the effect of this CR program on the improvement of myocardial function using the three-dimensional speckle tracking echocardiography (3D-STE) in AMI patients.
Recent studies suggest important gender differences in the pathophysiology and prognosis of ST-segment elevation myocardial infarction (STEMI). This is the first prospective controlled study to assess gender differences in the mechanism of plaque rupture/erosion and thrombus formation in patients presenting with STEMI treated with primary angioplasty. Gender-related mechanisms of plaque rupture or erosion will be investigated using a combination of Quantitative Coronary Angiography (QCA), high resolution Optical Coherence Tomography (OCT) of the culprit vessel and histopathology analyses of thrombus aspirates of the infarct related lesion, performed by independent core laboratories, blinded to group (male or female) and clinical variables. In OCTAVIA; enrollment in a 1:1 ratio according to gender group will be ensured by a computer-assisted matching algorithm for gender and age (< 50, 51-70, and > 70 years). Matching has the purpose to enable enrollment of an even number of male and female patients in balanced age groups. This type of dynamic algorithm is appropriate when the composition of the referral population is not known in advance. The sample size for the OCTAVIA study was calculated on the basis of per patient stent strut coverage (a continuous variable with right skewed distribution) with mean of 97.0% and standard deviation of 4.0% in men, versus mean of 95.0% and standard deviation of 4.0% in women, following XIENCE PRIME™ Everolimus Eluting Coronary Stent System implantation. Thus, aiming for a 5% 2-tailed superiority alpha, an 80% power, and assuming a 1:1 enrollment according to gender, a total of 64 patients per group should be enrolled. Anticipating a 10% dropout rate due to patients lost to follow-up and inadequate imaging (included major side branch sections), the total enrollment is set at 70 patients per group (total population of 140 subjects).
