Active clinical trials for "Infarction"

To date, the investigators have successfully employed a radiotracer (18F-sodium fluoride) as a marker of necrotic inflammation in human atherosclerosis. The investigators aim to further the mechanistic understanding of atherothrombosis by studying the activation of glycoprotein IIb/IIIa receptors in cardiovascular thrombus using the novel platelet radiotracer (18F-GP1). Binding of 18F-GP1 to activated platelets in venous and arterial thrombi has already been demonstrated in pre-clinical studies and a phase 1 trial in man. If successful, this study would define the role of the glycoprotein IIb/IIIa receptor within in vivo thrombosis across a range of cardiovascular diseases.

The size of the infarct is particularly important prognostic marker. It is clearly established that the extent of the infarct is not only correlated to mortality, but also long-term adverse events. The evaluation of the infarct size at the acute phase of the disease is therefore an essential clinical tool to adapt the immediate treatment and follow-up of patients. It is therefore crucial to have techniques that are effective, precise, reproducible, and easily performed during the acute phase to quantify the size of the infarct following angioplasty. Myocardial scintigraphy and cardiac MRI have been the standard examinations for the evaluation of infarct size. However, these exams are difficult to perform during the acute phase of the infarct owing to difficulties in monitoring unstable patients and the limited availability of the apparatus. It is for this reason that the investigators would like to investigate the rotational angiography (RA), which is comparable to a scanner in its mode of action but does not require transfer of patients as performed using the same apparatus that used for diagnostic coronarography and therapeutic angioplasty. RA is a radiological technique that uses the system employed for coronagraph, and consists rotating the fixed C-Arm around the patient and acquisition of a series of images that are then reconstituted. The investigators propose to evaluate the size of the infarct using RA in comparison with cardiac MRI (standard examination) performed as soon as possible after RA and the investigators hope to demonstrated that RA allows the measurement of an infarct as precisely as cardiac MRI.

The purpose of this study is to evaluate early preliminary efficacy of the eMotion intervention in US adults who have experienced a first cardiac event and participating in phase II cardiac rehabilitation. This study will evaluate early efficacy and evaluate the cognitive processes as intervention response variables. Investigators will also examine the relationships between emotion regulation and other cognitive processes and symptoms (threat and stress, cognition and motivation), symptoms [depression, anxiety, pain, sleep, and fatigue]), and health related quality of life among adults enrolled in cardiac rehabilitation after a first cardiac event.

In the literature, there are no studies comparing these two pathways in ST elevation myocardial infarction (STEMI). In this patient group, it will be investigated whether transulnar intervention causes similar or less complications than transradial intervention, and whether it provides superiority or similarity in terms of outcomes.

The purpose of this implementation trial is to execute a nurse-led, home-based cardiac rehabilitation (HBCR) program, evaluate the program's impact on patient outcomes over 6 months; and compare outcomes of HeartHome (HH) participants to a group of participants in traditional cardiac rehabilitation (CR).

Regular exercise in patients who have heart disease is highly beneficial and improves quality of life and survival. Exercise training is considered a core component of cardiac rehabilitation (CR), which is a multicomponent program delivered to patients who have heart disease. However, it is severely underutilized because people simply don't have the time or the resources to travel to a CR centre to attend rehab appointments. The investigators have developed a novel virtual reality (VR) based CR exercise system (MedBike). This system consists of an exercise bike attached to a VR world; it makes exercise engaging and fun. Furthermore, patients can be monitored during exercise remotely over the internet. The investigators intend to perform a pilot randomized controlled trial in which 10 patients are assigned to the MedBike system and 10 to standard CR. The investigators think that the MedBike system will increase exercise program compliance by providing an enjoyable and engaging exercise experience which can be performed in the comfort of one's own home. The investigators think that this will improve fitness (primary endpoint) in these patients. If the investigators demonstrate that home based exercise is feasible, the investigators plan a larger study to prove that it is something that should be broadly implemented in patients with heart disease.

This study aims to develop quality improvement strategies and relevant tools focusing on reperfusion therapy in patients with STEMI, and to evaluate their effectiveness via a hospital-level cluster randomized clinical trial, based on the nationally representative collaborative network of over 100 hospitals established in China PEACE retrospective study. In a baseline survey period, through consecutively recruiting all eligible inpatients and collecting relevant medical information, the performance of all participating hospitals before the implementation of the intervention will be assessed. During the following intervention period, 6-10 hospitals that show the strong willingness and ability to collaborate will be selected as "process optimization group". Their clinical pathways and team building will be re-organized for the purpose of quality improvement, and develop individualized treatment strategies and process. Meanwhile, other participating hospitals will be divided into intervention and control groups in a 1:1 ratio, in which the intervention group will take the treatment improvement strategy into implementation, while the control group will maintain the routine practice pattern. All hospitals will consecutively recruit qualified patients in the same method adopted in baseline period. Then the reperfusion rates and other performance measures will be compared among different groups (process optimization, intervention and control).

Psychosocial factors, including positive affect, finding meaning in the event, and managing emotional distress, influence prognosis following a heart attack or myocardial infarction (MI). Gratitude, typically defined as a feeling or attitude in acknowledgment of a benefit that one has received or will receive, is associated with higher levels of well-being, and people who are more grateful experience less stress, are less depressed, have higher levels of control over their environment, and more positive ways of coping. The present project will examine the potential benefits of a gratitude intervention (i.e., 8 weeks of gratitude journaling) to increase positive health behaviors, psychological health, and physical functioning in post-MI patients as compared to journaling about memorable events as well as care as usual alone. The investigators will study psychological and physical functioning at baseline, following 8 weeks of gratitude journaling or care as usual, and at 4-month follow-up.

The objective of this study is to evaluate the long-term plasma and urine pharmacokinetic parameters of Cardionat®, capsules 250 mg, when used in healthy athlete volunteers. The study consists of four steps: Step 1. Screening - selecting healthy volunteers for inclusion in the study; Step 2. Assignment in one of the study group, prescription of the study drug; Step 3. Samples collections for pharmacokinetic analysis; Step 4. Evaluation of pharmacokinetic data.

Remote ischaemic conditioning (RIC) is known to reduce infarct size post MI when used in the peri/immediate post infarct period. However little is known as to the effect of repeated remote conditioning post-MI (Myocardial Infarction) on not only infarct size, but also on ventricular remodeling and ultimately cardiac failure. In this phase II first in man trial, the investigators intend to carry out daily remote ischaemic conditioning in post MI patients. The principal hypothesis is that RIC applied on a daily basis for 4 weeks following a heart attack improves the ejection fraction at 4 months as assessed by cardiac magnetic resonance imaging.
