Active clinical trials for "Infarction"

A multi-center randomized post-approval evaluation of delivery of intracoronary hyperoxemic supersaturated Oxygen therapy for 60 minutes in anterior AMI patients with successful reperfusion (via PCI) within 6 hours after onset of symptoms compared to standard therapy

Patients with partially blocked blood vessel(s) in their heart may need a medical procedure called "Percutaneous Coronary Intervention (PCI)" to open the narrowed blood vessel(s). The purpose of this study is to simultaneously address four potential advances in ST-Elevation Myocardial Infarction (STEMI) care for patients at least 65 years old. The investigators are looking to see if these advances can improve the outcome for these patients. Opening the arteries with a Medtronic stent Radial access (from wrist) success with a Medtronic stent Checking the percent of blockage in the diseased artery/arteries using Volcano guide wires. Reduced bleeding and vascular complications with radial arterial access for primary PCI in STEMI.

Physiological cardiovascular stress test plays a crucial role in the assessment of patients with suspected heart disease. There are several methods of cardiac physiological stress tests and each of them offer varied insight into cardiac physiological adaptation: passive leg raise, intra-venous fluid challenge, pharmacological stressors and physical exercise stress test. Echocardiography, which is the mainstay for the non-invasive rest/stress assessment of the left ventricular (LV) haemodynamics has several limitations. Novel methods of CMR imaging allow to map intra-cardiac flow in three-dimension using novel flow acquisitions. These novel flow acquisitions are called four-dimensional flow CMR, where the fourth dimension is time. Additionally, traditional cine CMR imaging for functional assessment can now be done without breath-holds using advanced acceleration methods, allowing them to be used during exercise. A comprehensive understanding of functional-flow coupling at rest, during increased pre-load (fluid challenge) to the heart or during exercise, is lacking in the literature. There is an important need to validate these novel CMR methods for developing mechanistic insight into physiological cardiac adaptation to increased pre-load or to exercise in health and how it alters in heart disease.

The overall aim with the project is to evaluate if a digital patient group-education can reduce kinesiophobia and promote physical activity in patients with myocardial infarction (MI) and/or atrial fibrillation (AF) Research questions Can a digital patient group-education reduce kinesiophobia and promote PA in patients with MI and/or AF? Is a digital patient group-education feasible based on the patients' experiences? Intervention: Patients with MI and/or AF and kinesiophobia meet 7 times in a group education via Zoom® video meetings with a tutor (nurse, physiotherapist) for 8 weeks and learn about PA, kinesiophobia, AF and/or CAD. The education involves four real life scenarios as a starting point for the learning process inspired by problem-based learning, live stream/recorded lectures/resource, behavioral activation and exposure to PA in order to reduce kinesiophobia and promote PA.

In this randomized clinical trial, the researchers are investigating whether a multi-component virtual cardiac rehabilitation program in addition to usual care will improve functional status, cholesterol level, overall cardiovascular health, individual risk factors, quality of life and mental health for patients who have recently been diagnosed with atherosclerotic cardiovascular disease, as compared to usual care.

Favourable in-hospital outcome is observed in numerous patients after Non ST myocardial infarction (NSTEMI) with invasive strategy but European guidelines proposed systematic intensive care unit monitoring up to 24 h in lower risk patients (grade 1, level of evidence C). Regarding absence of prospective study supporting this strategy, we assessed the hypothesis that the lower risk NSTEMI patients identified through simple medical criteria and after coronary angiography evaluation may not require intensive care unit admission.

The goal of this cross over study is to investigate the effect of short term time restricted eating (TRE) on the innate immune system in patients with a history of myocardial infarction.

This randomized control trial seeks to better understand the educational needs of Acute Coronary Symptom (ACS) patients including the optimal timing and method of delivery as well as linkages with appropriate community resources and supports are important for cardiac patients to self-manage post hospital discharge to improve outcomes. While there is some literature of the learning needs of ACS patients, there is a paucity of research related to the timing and preferred methods of delivery. This study aims to better understand how best to tailor care for ACS patients from hospital to community. Specifically, the investigators propose a 2 phased approach to understand the needs of patients, and then to develop and deliver a tailored approach to assess, educate and support patients both in-hospital and within the community. The intervention compares 1) a virtual remote home monitoring (RHM) platform and 2) Rapid Response Nursing (RRN) staff to follow, educate and support ACS patients post hospital discharge for a period of no more than 30 days. The Primary Objective of this study is to safely transition low risk ACS patients, from hospital to home, with appropriate supports to safely self-manage in the community and to provide educational and community supports to improve post discharge outcomes of low risk ACS patients

The present study focusses on the effects of the diagnostic testing environment on psychological wellbeing, cardiac symptoms and patient satisfaction during cardiac stress testing (CST) in patients who are referred to the Institute Verbeeten for SPECT myocardial perfusion imaging (MPI). The diagnostic procedure consists of two days of MPI using SPECT: day 1 of MPI involves obtaining a resting image and day 2 (typically 3 or 4 days later) a stress MPI following exercise or pharmacological challenge with adenosine. The diagnostic procedure can result in undesirable effects on psychological wellbeing, such as anxiety or psychological distress. These effects can be related to anticipatory anxiety (day 1 of MPI) and/or responses to the exercise or adenosine stress testing (day 2 of MPI). The present investigation aims to develop methods to further improve patients' experiences and wellbeing during the diagnostic process for the presence of inducible myocardial ischemia. This research project will compare four groups to establish the effect of providing information and supportive coaching: (1) care as usual, (2) information support using video materials, (3) supportive coaching during the diagnostic testing procedure, and (4) a combination of both interventions. The video-based information and supportive coaching are aimed at reducing feelings of anxiety, uncertainty and psychological distress during the diagnostic testing procedure. In addition to standardized self-report questionnaires, this project will utilize facial expression analysis software to measure emotional states during CST as well as 24- hour ambulatory assessments to evaluate autonomic nervous system activity, cardiac symptoms and psychological wellbeing during everyday life activities in the period between the two days of MPI. It is hypothesized that additional video-based information and supportive coaching during the diagnostic process for the inducibility of myocardial ischemia will result in improved psychological wellbeing (reduced acute negative emotions; primary outcome) as well as less cardiac and other physical symptoms and improved patient satisfaction (secondary outcomes) of the diagnostic clinic visit. The innovative aspect of the present proposal is its focus on emotional expression during evaluation for myocardial ischemia using FaceReader software in combination with self-reported momentary mood and perceived stress assessments. Knowledge about the interaction between psychological wellbeing and cardiac function obtained in this project will strengthen the development of future interventions aimed to reduce symptom burden and psychological distress in patients undergoing diagnostic evaluations for heart disease.

Aim: To develop and field test an Integrative Cardiac Rehabilitation Employing Smartphone Technology (I-CREST) system, and evaluate its effects on CR utilization, cardiac self-efficacy, functional capacity, health-related quality of life (HRQoL), anxiety, depression, medication adherence, cardiac risk factor control and clinical outcomes among post-myocardial patients in Singapore. Background: Centre-based cardiac rehabilitation (CBCR) participation rates among eligible patients remain low at 10-30% worldwide and less than 10% in Singapore, reportedly due to long-standing challenges surrounding accessibility, conflicting commitments, low socioeconomic status, and costs. A recent challenge is the COVID-19 pandemic, that resulted in the partial or complete closures of CBCR programmes Alternative strategies to deliver cardiac rehabilitation using novel technologies are needed to increase participation rates and improve health outcomes. Design: A single-blinded two-arm randomised controlled trial (RCT) will be adopted. Methodology: The is a two-phase study. Phase one involves the development and field-testing of the I-CREST system. The I-CREST system comprises of a smartphone application, a wearable heart rate monitor and a web-portal. Phase two is a single-blinded two-arm RCT with repeated measures. 124 participants will be recruited from the National University Hospital in Singapore and will be randomly allocated to intervention or control group. Participants in the intervention group will receive the 6-week I-CREST intervention - including the newly developed I-CREST system, one face-to-face training session, and weekly telephone calls. The participants in the control group will receive the 4-week traditional CBCR. Data will be collected at baseline, at 6 weeks (after completion of the CR programme), at 3months and at 6months from baseline. Sociodemographic and clinical data will also be collected. A cost-effectiveness analysis will also be performed to evaluate the feasibility of I-CREST compared to the CBCR platform. To assess the participants' experiences of the I-CREST system, a process evaluation will be undertaken at the conclusion of the study. Significance. This study will generate insights into the suitability and effectiveness of I-CREST as an alternative to traditional CBCR outpatient services.
