Filter by:This is a randomized, double blind, placebo controlled study of intracoronary cocktail injection combined with thrombus aspiration versus thrombus aspiration alone in ST-elevation myocardial infarction patients treated with primary angioplasty.
The investigators planned to evaluate the effects of liraglutide on left ventricular function in patients with non-ST-segment elevation myocardial infarction (NSTEMI).
NP202 is an experimental drug being developed by Armaron Bio Pty Ltd for potential use as a treatment for people after they have had a heart attack (MI).
Approximately 60 patients with ST-segment elevation myocardial infarction successfully treated with primary percutaneous coronary intervention will be enrolled and randomized to receive the sodium tanshinone IIA sulfonate in addition to standard therapy or the same volume/day of normal saline. The primary endpoint is the variation in LV end-diastolic volume index (LVEDVi) assessed with cardiac magnetic resonance imaging (MRI) at baseline and 6 months.
A measurable degree of heart muscle tissue injury is expected in patients undergoing heart valvular surgery. The level of this injury can be measured by cardiac biomarkers in blood samples. Those biomarkers are used to diagnose an acute myocardial infarction. Postoperative myocardial infarction (MI) is a frequent and important complication after cardiac surgery with high morbidity and mortality. Therefore it is very important to recognize any cardiac event in patients who undergo cardiac surgery. Different diagnostic tools can be used to the diagnosis of acute myocardial infarction; however few is known about the value of high-sensitivity cardiac troponin T (hs-cTn) to diagnose a MI after heart valvular surgery. The aim of this study is to determine the upper reference limit of high-sensitivity troponin T concentration to consider the diagnosis of acute myocardial infarction in patients undergoing heart valvular surgery.
Based on accumulating evidences showing that hypothyroid status is associated with poor prognosis among acute myocardial infarction (AMI) patients, the study is designed to evaluate whether replacement treatment with levothyroxine could have beneficial effects on patients with AMI and hypothyroidism. This is a multicenter prospective computerized-randomized trial stratified by ejection fraction with a 1:1 ratio to levothyroxine group or standard therapy group.
Cardiac exploration almost systematically requires the acquisition and / or calculating function indices. The ejection fraction (LVEF) is probably based index most widely used in all cardiac exploration methods. This relatively universal overall index has very many qualities. LVEF is widely used in clinical practice through the exploration and monitoring of all heart disease. Current progress in the management of various cardiomyopathies pass through the detection of early attacks. This testing often takes place upstream changes in LVEF that remains long normal or normalized. Sensitive indicators capable of detecting early abnormalities of regional functions are essential in addition to conventional echocardiography. Various studies have shown the contribution of these new markers in early detection of abnormalities of the cardiac function. The most widely used indicator in these studies because of its high sensitivity to analyze the movements of the heart is the tissue Doppler. Tissue Doppler however has limitations in particular its dependence on the incident angle, which makes it impossible to correct analysis of non-aligned in the axis of the ultrasonic beam components. A new way of exploring the regional function of the heart, speckle tracking, can analyze heart deformations along the principal axes of the heart. The advantage of this technique has been shown in various pathological situations. Currently, this technique is mostly used in longitudinal and transverse view 2D imposing multiple planes cuts. 3D potential of this technique is not currently known, acquisition of 3D technology is recent (2004) and dedicated software is confidential dissemination and unvalidated. The validated technique, 3D reference analysis of myocardial deformation is tagged MRI. In the 90s, studies have demonstrated the feasibility of this technique, the ability to access all of the myocardial deformation in space and to define normal values. The cost of the procedure, duration, limited accessibility and post-processing very time consuming limited the scope of the clinical benefits of this modality. Echocardiography has major advantages over MRI, particularly its high availability, low cost and flexibility of use. The ability to access with MRI as the 3D deformation of the heart is a new opportunity that it is essential to validate. The main purpose of the study is to compare the strain values obtained 3D ultrasound to those obtained by MRI tagged in a control group and a group of subjects with an anterior infarction sequela.
The investigators planned to evaluate the effects of liraglutide on no-reflow in patients with acute ST-segment elevation myocardial infarction (STEMI).
The objective of Left atrial appendage closure compared to standard antiplatelet therapy in patients with AF who underwent percutaneous coronary intervention (LLA-PCI) study is to evaluate the safety and efficacy of implantation of left atrial appendage closure compared to standard antiplatelet therapy for prevention of thromboembolic events and stent thrombosis in subjects with AF who underwent PCI.
Aim. To develop and examine the effectiveness of an APN-led telehealth rehabilitative programme as a transitional nursing therapeutic on readmission rates and health related outcomes amongst patients with Acute Myocardial Infarction (AMI) post discharge. Design. Randomized controlled trial with repeated measures. Methodology. A consecutive sampling of 172 patients with AMI will be recruited from a tertiary hospital in Singapore. Participants will be randomised into two groups. The experimental group (ALTRA) will receive APN-led telehealth rehabilitative programme upon discharge in addition to standard care. The control group will receive only standard follow-up care.
