Filter by:Heart scarring, also known as fibrosis, plays a major role in a lot of heart muscle abnormalities. These abnormalities of the heart muscle can lead to major issues such as symptoms of heart failure, dangerous heart rhythm disturbances and even death. However, a lot of these conditions are still not fully understood and treatment options are limited. We here aim to use a new radioactive dye called 68Ga-FAPI to identify patterns and the activity of heart muscle scarring. This radioactive dye is being used in humans particularly in identifying and monitoring cancers and has shown promise in identifying scarring in the heart as well. This will help us not only understand the underlying disease process and risk stratify these patients but also potentially help us develop new targeted therapies that can affect heart muscle scarring. Participants will undergo a baseline MRI scan using this new dye and a plain MRI scan will repeated 12-18 months after to see if there are any changes in the process.
To handle daily life challenges, one needs to be psychologically resilient. It plays a crucial role in disease development, prognosis, as well as social, occupational, and community participation. Cardiovascular diseases cause physical and psychological stress, which can be linked to individual resilience and the development of such diseases. Stress can trigger TakoTsubo cardiomyopathy and acute coronary events. Individuals who have experienced TakoTsubo cardiomyopathy or an acute coronary event often feel stressed due to emotional or physical triggers. These triggers may include job loss or illness. In medical rehabilitation, therapists consider the individual circumstances of their patients when planning therapy. It may be important to add a special focus on psychological care, including building resilience, which could greatly benefit these individuals. Therefore, the study aims to investigate whether resilience training, as part of an inpatient multidisciplinary rehabilitation program, affects the individual resilience of rehabilitants with TakoTsubo cardiomyopathy or those who have experienced an acute coronary event.
This clinical study examines patients presenting with acute myocardial infarction and no significant coronary artery disease on coronary angiography (MINOCA) and patients with MINOCA-mimics with advanced CMR. The present study aims to: - assess the microvascular function with a novel quantitative 3D myocardial perfusion imaging approach in the acute phase and post-convalescence - refine the role and diagnostic potential of advanced quantitative CMR imaging - assess the potential prognostic significance of microvascular dysfunction and epicardial adipose tissue on cardiovascular outcomes Participants will undergo advanced CMR imaging in the acute setting (within 10 days after event) and post convalescence (after 3 months).
The primary objective of this observational registry is to develop a comprehensive clinical and imaging score (incorporating echocardiography and cardiac magnetic resonance data) that enhances risk stratification for patients with Takotsubo syndrome. The secondary objectives of this registry are as follows: Investigate the diagnostic value of cardiac magnetic resonance parameters in predicting in-hospital and long-term outcomes in patients with Takotsubo syndrome. Compare the proposed risk stratification score for patients with Takotsubo syndrome with previously existing scores. Investigate the contribution of machine learning models in predicting in-hospital and long-term outcomes compared to standard clinical scores. The design and rationale of this registry are available at 10.1097/RTI.0000000000000709
The study hypothesis is that participants enrolled in a virtual Takotsubo support group will have significantly less anxiety at one year.
The goal of this clinical trial is to investigate the impact of repetitive acute Cyclosporine A (CsA) bolus therapy in patients suffering from TTS with an elevated risk of impaired outcome. The main question it aims to answer is whether CsA reduces myocardial injury (primary outcome). Participants will receive CsA or placebo at baseline and every 12h in the first 24h after study inclusion. Researchers will compare CsA and the placebo group to see if a) myocardial injury is reduced, and b) ejection fraction is improved compared to baseline, as well as several other secondary endpoints over a one year follow-up.
The overall aim of the study is to establish the clinical importance of cardiac dysfunction, by estimating its incidence and impact on short- and long-term outcomes, in a mixed population of critically ill patients with multi-organ failure. Pathogenesis of cardiac dysfunction in critical illness and key molecules linked to this will be explored.
Takotsubo syndrome (TTS) is an acute and reversible form of myocardial injury often preceded by a physical or emotional trigger. Although TTS was generally considered a benign disease for its reversible nature, it is now clear that hemodynamic and electrical instability during the acute phase exposes patients to frequent serious adverse in-hospital complications. However, the pathophysiology of TTS is far from being completely understood. Consistent evidence demonstrated that the environmental events experienced by most of these patients and perceived as stressful (both physical or emotional) induce a brain activation and a stress-related response, with increasing bioavailability of local and circulating stress mediators, such as catecholamine and cortisol, which showed to play a major role in the etiology of to the "neurogenic stunning myocardium" responsible for this clinical condition. Primary and secondary TTS showed an important clinical heterogeneity identifying two different subtypes of patients with different outcomes and risk profiles. the invastigators hypothesize that a different activation of the brain structures involved in acute stress response, as well as a different exposure to chronic stress, may subtend the different clinical and risk profiles observed in primary vs. secondary TTS patients. Moreover, the invastigators hypothesize that distinct signatures of circulating biomarkers may be associated with these two categories of TTS patients. Therefore, identifying these specific signatures may help in the diagnosis of these patients and pave the way for the identification of specific pathophysiologic pathways and the development of future therapies.
The primary objective of this prospective, observational study is to compare muscle sympathetic nerve activity at rest and during stress between female patients with Takotsubo syndrome and healthy, matched volunteers. - Do Takotsubo patients have an increased sympathetic nerve activity compared to controls? - Do Takotsubo patients have an exaggerated sympathetic nerve activity response to stress? - Does the sympathetic nerve activity response to stress in Takotsubo change after receiving the beta blocking agent metoprolol? Participants will be examined with muscle sympathetic nerve activity recording in the peroneal nerve at rest and during cold pressor test. After intravenous injection with beta blocking agent (metoprolol) or placebo (saline) in a 1:1 randomized fashion, muscle sympathetic nerve recording at rest and during stress will be repeated.
Takotsubo syndrome (TTS) is an acute and reversible form of myocardial injury characterized by typical regional wall motion abnormalities in the absence of culprit epicardial coronary artery disease frequently precipitated by significant emotional stress or serious physical illness. The clinical presentation is usually similar to acute myocardial infarction (MI), with chest pain and/or dyspnea, ST-segment elevation or depression and/or T-wave inversion on the resting electrocardiogram (ECG) and elevation of serum cardiac troponin. Although previously considered a benign disease, it is now clear that TTS is associated with severe acute complications during the acute phase including hemodynamic and electrical instability and up to 5% of in-hospital mortality. The pathogenetic mechanisms of air pollution are likely to predispose to the occurrence as well as to mediate a worse clinical presentation and outcome of TTS, proving air pollution as a TTS risk factor.
