Background: The perception of takotsubo syndrome (TTS) has evolved significantly over the years, primarily driven by increased recognition of acute complications and mortality., Objectives: This study aimed to explore temporal trends in demographic patterns, risk factors, clinical presentations, and outcomes in patients with TTS., Methods: Patients diagnosed with TTS between 2004 and 2021 were enrolled from the InterTAK (International Takotsubo) registry. To assess temporal trends, patients were divided into 6 groups, each corresponding to a 3-year interval within the study period., Results: Overall, 3,957 patients were included in the study. There was a significant demographic transition, with the proportion of male patients rising from 10% to 15% (P = 0.003). Although apical TTS remained the most common form, the diagnosis of midventricular TTS increased from 18% to 28% (P = 0.018). The prevalence of physical triggers increased from 39% to 58% over the years (P < 0.001). There was a significant increase in 60-day mortality over the years (P < 0.001). However, a landmark analysis excluding patients who died within the first 60 days showed no differences in 1-year mortality (P = 0.150)., Conclusions: This study of temporal trends in TTS highlights a transition in patients demographic with a growing prevalence among men, increasing recognition of midventricular TTS type, and increased short-term mortality and rates of cardiogenic shock in recent years. This transition aligns with the rising prevalence of physical triggers, as expression of increased recognition of TTS in association with acute comorbidities., Competing Interests: Funding Support and Author Disclosures Dr Templin has received institutional grants from Abbott Vascular, Medtronic, and SMT; and has received consulting grants from Biotronik, Microport, and Innova.

Background: Takotsubo syndrome (TTS) occurs predominantly in post-menopausal women but is also found in younger patients., Objectives: This study aimed to investigate age-related differences in TTS., Methods: Patients diagnosed with TTS and enrolled in the International Takotsubo Registry between January 2011 and February 2017 were included in this analysis and were stratified by age (younger: ≤50 years, middle-age: 51 to 74 years, elderly: ≥75 years). Baseline characteristics, hospital course, as well as short- and long-term mortality were compared among groups., Results: Of 2,098 TTS patients, 242 (11.5%) patients were ≤50 years of age, 1,194 (56.9%) were 51 to 74 years of age, and 662 (31.6%) were ≥75 years of age. Younger patients were more often men (12.4% vs. 10.9% vs. 6.3%; p = 0.002) and had an increased prevalence of acute neurological (16.3% vs. 8.4% vs. 8.8%; p = 0.001) or psychiatric disorders (14.1% vs. 10.3% vs. 5.6%; p < 0.001) compared with middle-aged and elderly TTS patients. Furthermore, younger patients had more often cardiogenic shock (15.3% vs. 9.1% vs. 8.1%; p = 0.004) and had a numerically higher in-hospital mortality (6.6% vs. 3.6% vs. 5.1%; p = 0.07). At multivariable analysis, younger (odds ratio: 1.60; 95% confidence interval: 0.86 to 3.01; p = 0.14) and older age (odds ratio: 1.09; 95% confidence interval: 0.66 to 1.80; p = 0.75) were not independently associated with in-hospital mortality using the middle-aged group as a reference. There were no differences in 60-day mortality rates among groups., Conclusions: A substantial proportion of TTS patients are younger than 50 years of age. TTS is associated with severe complications requiring intensive care, particularly in younger patients., (Copyright © 2020 American College of Cardiology Foundation. Published by Elsevier Inc.

Background: Prognosis of Takotsubo syndrome (TTS) remains controversial due to scarcity of available data. Additionally, the effect of the triggering factors remains elusive., Objectives: This study compared prognosis between TTS and acute coronary syndrome (ACS) patients and investigated short- and long-term outcomes in TTS based on different triggers., Methods: Patients with TTS were enrolled from the International Takotsubo Registry. Long-term mortality of patients with TTS was compared to an age- and sex-matched cohort of patients with ACS. In addition, short- and long-term outcomes were compared between different groups according to triggering conditions., Results: Overall, TTS patients had a comparable long-term mortality risk with ACS patients. Of 1,613 TTS patients, an emotional trigger was detected in 485 patients (30%). Of 630 patients (39%) related to physical triggers, 98 patients (6%) had acute neurologic disorders, while in the other 532 patients (33%), physical activities, medical conditions, or procedures were the triggering conditions. The remaining 498 patients (31%) had no identifiable trigger. TTS patients related to physical stress showed higher mortality rates than ACS patients during long-term follow-up, whereas patients related to emotional stress had better outcomes compared with ACS patients., Conclusions: Overall, TTS patients had long-term outcomes comparable to age- and sex-matched ACS patients. Also, we demonstrated that TTS can either be benign or a life-threating condition depending on the inciting stress factor. We propose a new classification based on triggers, which can serve as a clinical tool to predict short- and long-term outcomes of TTS.
