The Evolving Features of Takotsubo Syndrome.
Curr Cardiol Rep
January 2025
Berne Cardiovascular Research Center and Division of Cardiology, University of Virginia, Charlottesville, USA.
Purpose Of The Review: Takotsubo syndrome (TTS) is a transient form of left ventricular dysfunction, typically affecting post-menopausal females, often preceded by emotional or physical stressful events that act as triggers. Initially believed to be a rare and benign condition for its reversible nature, TTS has recently emerged as a complex multifaceted clinical entity, with heterogenous clinical presentations and a non-negligible risk of serious in-hospital complications, including acute heart failure, arrhythmias and death.
Recent Findings: Emerging pathophysiological hypotheses, ranging from microvascular dysfunction to systemic inflammation, offer new insights into the underlying mechanisms of TTS.
Myocardial microvascular function assessed by cardiovascular magnetic resonance first-pass perfusion in patients with Takotsubo syndrome.
Eur Radiol
January 2025
Department of Radiology, Azienda Ospedaliero Universitaria (A.O.U.), di Cagliari-Polo di Monserrato s.s. 554 Monserrato (Cagliari), Cagliari, 09045, Italy.
Objective: The purpose of this study was to explore microvascular function impairment using first-pass cardiovascular magnetic resonance (CMR) in patients with Takotsubo syndrome (TS). Moreover, we explored myocardial microcirculation in patients with TS and related this to demographic data, cardiovascular risk factors, clinical parameters, cardiac biomarkers, and cardiac function.
Methods: This retrospective study performed CMR first-pass perfusion scans in 42 consecutive patients with TS (37 females, 70.
A dynamic variant of Takotsubo cardiomyopathy mimicking apical hypertrophic cardiomyopathy: a case report.
Eur Heart J Case Rep
January 2025
Cardiovascular and Thoracic Division, Cardiology Department, University Hospital Southampton, Tremona Road, Southampton SO16 6YD, UK.
Background: Takotsubo cardiomyopathy usually presents with acute reversible left ventricular apical hypokinesia and apical ballooning with basal hyperdynamic function. We describe an underreported case of Takotsubo cardiomyopathy (TCM), misinterpreted as apical hypertrophic cardiomyopathy (HCM) due to transient apical oedema in the recovery phase of the condition.
Case Summary: A 74-year-old Caucasian woman, presented to the emergency department complaining of retrosternal chest pain following, emotional stress.
Fulminant immune checkpoint inhibitor-associated myocarditis bridged to recovery with a temporary left ventricular assist device: a case report.
Eur Heart J Case Rep
January 2025
Cardiology Department, Loyola University Medical Center, 2160 S 1st Ave, Maywood, IL 60153-3328, USA.
Background: Immune checkpoint inhibitors (ICIs) are effective antineoplastic agents but can cause adverse effects in many organ systems. Cardiovascular toxicities include arrhythmias, myocarditis, heart failure, takotsubo syndrome, pericarditis, coronary artery disease, and vasculitis.
Case Summary: A 66-year-old woman with Stage 3C2 endometrial carcinoma presented for her second cycle of pembrolizumab, carboplatin, and paclitaxel.
Sacubitril/valsartan attenuates inflammation and myocardial fibrosis in Takotsubo-like cardiomyopathy.
J Mol Cell Cardiol

Department of Cardiology, The Second Hospital, Cheeloo College of Medicine, Shandong University, Jinan, Shandong 250031, PR China. Electronic address:
Background: Takotsubo syndrome (TTS) primarily manifests as a cardiomyopathy induced by physical or emotional stress, remains a poorly understood condition with no established treatments. In this study, we investigated the potential of sacubitril/valsartan (sac/val) to increase the survival of TTS patients and reduce inflammation and myocardial fibrosis in experimental models.
Aim: This study aimed to evaluate whether sac/val could improve survival rates in TTS patients, mitigate cardiac remodeling in vivo, and explore its anti-inflammatory and antifibrotic mechanisms in vitro.
