Autonomic Modulation in Takotsubo Syndrome

This is a minimal risk case-controlled single arm intervention study, including 10 patients with a prior history of takotsubo and 10-age and sex matched healthy controls. Subjects will undergo in laboratory testing to measure autonomic function. They will then undergo a 15-week program of device-guided breathing with remote measures of autonomic function obtained at home. Analysis will determine the reproducibility of home autonomic measures and the provide preliminary data to determine the efficacy of device-guided breathing on autonomic measures and quality of life in patients with takotsubo.

The GErman Italian Spanish Takotsubo (GEIST) Registry

GEIST is a multicenter, international observational registry of patients with Takotsubo syndrome. Data regarding the clinical profile (demographic characteristics, clinical presentation, laboratory measures, electrocardiography /echocardiography / coronary angiography parameters, treatment and medication), in-hospital course and complications and short-/long-term outcome are collected prospectively and retrospectively to increase the understanding of the disease.

Mechanisms And Prognosis of Stroke-Heart Syndrome

The incidence of stroke-heart syndrome following acute stroke, which encompasses both acute ischemic stroke and acute intracerebral hemorrhage, is notably high and is strongly associated with increased mortality and poor outcomes in stroke patients. However, the underlying mechanisms remain unclear, and there are currently no effective prevention or treatment strategies. This study aims to elucidate the neuro-humoral mechanisms of stroke-heart syndrome through multimodal imaging and multi-omics blood analysis. Additionally, it seeks to observe the progression of stroke-heart syndrome and its impact on functional outcomes, cognitive abilities, and emotional issues post-stroke. The research is expected to uncover novel blood biomarkers and brain network mechanisms associated with stroke-heart syndrome, providing potential targets and theoretical foundations for pharmacological treatments or physical interventions. Furthermore, it aims to establish a risk early-warning system for major cardiovascular complications post-stroke, enabling early identification, early intervention, and integrated brain-heart management to improve clinical outcomes for stroke patients.

BROKEN-SWEDEHEART- Optimized Pharmacological Treatment for Broken Heart (Takotsubo) Syndrome.

The aim of this study is to document an optimized pharmacologic treatment for patients with Takotsubo Syndrome. There is currently no published documentation in a large number of patients. The study is a Randomized Registry Clinical Trial and in total 1000 patients registered in SWEDEHEART will be included.

Italian Multicenter Observational Registry on Takostubo Syndrome

Takotsubo syndrome (TTS) has recently been described as an acquired form of cardiomyopathy whose pathophysiology is not yet well understood and mainly affects postmenopausal women. TTS or "broken heart" syndrome was first described in Japan in 1991. The Japanese term "tako-tsubo" means "polyp vessel" and describes the morphology of the left ventricular apex during systole in patients with this condition. The onset usually follows physical or emotional stress and mimics that of acute coronary syndrome (ACS) with a parade of symptoms, including chest pain, dyspnea, syncope, and nausea. Objective examination is often normal or otherwise nonspecific. ECG may document ST-T changes while echocardiogram shows areas of altered ventricular kinetics. Serum cardiac biomarkers may be increased. Currently, the gold standard method for the diagnosis of TTS is coronarography, which documents epicardial coronary arteries that are normal or free of critical lesions. It is estimated that more than 2.5% of patients with a suspected diagnosis of ACS have TTS, and this number is probably underestimated. Although the prognosis of TTS is generally considered favorable, during the acute phase these patients can develop potentially fatal complications such as ventricular arrhythmias, cardiogenic shock, and heart rupture. Moreover, emerging scientific evidence sheds light on the need to adopt a dedicated diagnostic-therapeutic pathway for this type of patients. The exact pathophysiology of TTS is still unknown and no large population studies or registries are currently available. Therefore, the purpose of the study is to better characterize the profile of this disease through the creation of a large registry.

Takotsubo Syndrome and Air Pollution

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.
