Filter by:The goal of this study is to develop a prognostic score for ischemic posterior circulation strokes, based on our previous work on with the ASTRAL scores (Acute STroke Registry and Analysis of Lausanne) on overall stroke prognosis, intracranial occlusion, recanalization and stroke recurrences. The main question it aims to answer is the modified Rankin score in 3 months after the event. Participants will be patients with acute ischemic stroke of the posterior circulation with mRS priot to event <3. All the data will be collected retrospectively from patients included in the ASTRAL registry between January 2003 and December 2021. The ASTRAL registry will be used as the derivation cohort of the score. Demographics, acute glucose, NIHSS score and acute imaging of each participant will be used from the derivation cohort in order to create an integer-based prognostic score. After internal validation, we plan to validate the score in external stroke registries to show its validity.
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.
The Mindray High Sensitivity Troponin-I Measurement System is an in vitro diagnostic test for the quantitative determination of high sensitivity cardiac troponin I (hs-cTnI) in human serum or plasma. The Mindray High Sensitivity Troponin-I Measurement System is to be used as an aid in the diagnosis and rule out of acute myocardial infarction (AMI).
The goal of this clustered, diagnostic randomized controlled trial is to study a clinical decision rule including a high-sensitive troponin I point of care test in patients with chest pain in primary care. The main questions it aims to answer are: 1. Can unnecessary referrals to secondary care be reduced by the use of a clinical deci-sion rule in patients with new onset, non-traumatic chest pain in primary care? Compared to current daily practice. 2. What is the accuracy (sensitivity, negative prediction value) of the clinical decision rule for excluding ACS and MACE at 6 weeks and 6 months?
There are limited data on how the guideline indications for ICD implantation are applied in clinical practice across Europe. Moreover, the impact of "time-dependence" of some indications to implantation on the guidelines adherence is still unknown. Objective of the present observational study is the evaluation of the adherence to the scientific guidelines in patients with a time-dependent indication to ICD/CRT-D implantation admitted to an in-hospital cardiac rehabilitation program.
The current ST-segment elevation (STEMI)/non-STEMI treatment paradigm misses nearly one fourth of acute coronary occlusions (ACO) that needs immediately reperfusion. Many of these cases can be recognized by subtle changes on ECG, but the current STEMI criteria do not include them. The investigators of this research believe a new occlusive/non-occlusive myocardial infarction (OMI/NOMI) approach will be superior to the established STEMI/non-STEMI paradigm in early detection of ACO, limiting infarct size, reducing re-hospitalizations and most important of all, reducing mortality.
The primary objective is to explore if HRS8179 could improve midline shift at 72 hours (or at time of decompressive craniectomy or comfort measures only, if earlier) in participants with large hemispheric infarction. The secondary objective is to explore if HRS8179 could improve acute neurologic status, functional outcomes, treatment requirements and safety.
Patients with chest pain and persistent ST segment elevation (STE) may not have acute coronary occlusions or serum troponin curves suggestive of acute necrosis. Our objective is the validation and cost-effectiveness analysis of a diagnostic model assisted by artificial intelligence (AI). Our hypothesis is that an AI analysis of the surface electrocardiogram allows a better distinction of patients with STE due to acute myocardial ischemia, from those with another etiology. This is a prospective multicenter study with two groups of patients with STE: I) coronary arteries without significant lesions and without serum troponin curve suggestive of acute necrosis, II) myocardial infarction with acute coronary occlusion. A manual centralized electrocardiographic analysis and another by AI algorithms will be performed.
In this study, the investigators evaluated the association between various measures of adiposity [BMI and waist circumference (WC)] and clinical outcomes in Asian patients with Myocardial Infarction who underwent percutaneous coronary intervention or bypass surgery, using a nationwide population based cohort.
The goal of this observational multi-center study is to evaluate the clinical performance of the i-STAT hs-TnI test (i-STAT High Sensitivity Troponin I) using the investigational i-STAT hs-TnI cartridge for the proposed intended use as an aid in the diagnosis and treatment of myocardial infarction (MI). The cartridge measures cardiac troponin I (cTnI) in whole blood or plasma samples using the i-STAT 1 Analyzer or i-STAT Alinity Instrument. Subjects presenting to the emergency department (ED) with chest discomfort or equivalent ischemic symptoms suggestive of Acute Coronary Syndrome (ACS) who are enrolled in this study will be asked to provide blood samples for testing.
