Short- and Long-Term Prognosis of Patients With Takotsubo Syndrome Based on Different Triggers: Importance of the Physical Nature
Background
Takotsubo syndrome (TTS) is an acute reversible heart condition initially believed to represent a benign pathology attributable to its self-limiting clinical course; however, little is known about its prognosis based on different triggers. This study compared short- and long-term outcomes between TTS based on different triggers, focusing on various physical triggering events.
Methods and Results
We analyzed patients with a definitive TTS diagnosis recruited for the Spanish National Registry on TTS (RETAKO [Registry on Takotsubo Syndrome]). Short- and long-term outcomes were compared between different groups according to triggering factors. A total of 939 patients were included. An emotional trigger was detected in 340 patients (36.2%), a physical trigger in 293 patients (31.2%), and none could be identified in 306 patients (32.6%). The main physical triggers observed were infections (30.7%), followed by surgical procedures (22.5%), physical activities (18.4%), episodes of severe hypoxia (18.4%), and neurological events (9.9%). TTS triggered by physical factors showed higher mortality in the short and long term, and within this group, patients whose physical trigger was hypoxia were those who had a worse prognosis, in addition to being triggered by physical factors, including age >70 years, diabetes mellitus, left ventricular eyection fraction <30% and shock on admission, and increased long-term mortality risk.
Conclusions
TTS triggered by physical factors could present a worse prognosis in terms of mortality. Under the TTS label, there could be as yet undiscovered very different clinical profiles, whose differentiation could lead to individual better management, and therefore the perception of TTS as having a benign prognosis should be generally ruled out
Renal impairment and outcome in Takotsubo syndrome: Insights from a national multicentric cohort
ntroduction: Data on the association between kidney function and Takotsubo syndrome (TTS) outcomes are scarce and conflictive.
Objective: To assess the impact of chronic kidney disease (CKD) and acute renal failure (ARF) in patients with TTS.
Material and methods: Patients from the prospective nation-wide (RETAKO) registry were included and divided into quartiles of maximum creatinine (Cr) level during hospitalization.
Results: The prevalence of CKD and ARF in the whole RETAKO cohort was 5.4% and 11.7%, respectively. Compared to Q1 (Cr 1.1) had lower left ventricular ejection fraction on admission (38.5 ± 12 vs 43.3 ± 11.3, p = 0.002) and higher bleeding rates during hospitalization (6.7% vs 2%, p = 0.005). In addition, compared to Q1, Q4 patients have a greater incidence of cardiogenic shock (17.3% vs 5.6%, p < 0.001), and a higher rate of 5-year all-cause death and major adverse cardiovascular events (31.5% vs 15.8%, p < 0.001 and 22.5% vs 9.3%, p < 0.001, respectively).
Conclusions: TTS patients with CKD have a higher incidence of ARF and exhibit greater Cr on admission, which were linked with higher rates of cardiogenic shock, bleeding during hospitalization as well as major adverse cardiovascular events and all-cause death during a 5-year follow-up.Sociedad Española de CardiologĂaMayo Clinic3.5 Q1 JCR 20221.126 Q1 SJR 2023No data IDR 2022UE

Antiplatelet therapy at discharge and long-term prognosis in Takotsubo syndrome: Insights from the Spanish National Registry (RETAKO).
Endothelial dysfunction and platelet activation have been highlighted as possible mediators in Takotsubo syndrome (TTS). Nevertheless, to date, evidence on the usefulness of antiplatelet therapy in TTS remains controversial. The aim of our study is to evaluate long-term prognosis in TTS patients treated with antiplatelet therapy (APT) at hospitalization discharge. An ambispective cohort study from the Spanish National Takotsubo Registry database was performed (June 2002 to March 2017). Patients were divided into two groups: those who received APT at hospital discharge (APT cohort) and those who did not (non-APT cohort). Primary endpoint was all-cause death. Secondary endpoints included the composite of recurrence or readmission and a composite of death, recurrence or readmission. From a total of 741 patients, 728 patients were alive at discharge. Follow-up was performed in 544 patients, who were included in the final analysis: 321 patients (59.0%) in the APT cohort and 223 patients (41.0%) in the non-APT cohort. The APT cohort had a better clinical presentation and received more heart failure and acute coronary syndrome-like therapies (angiotensin converting enzyme inhibitors/angiotensin receptor blockers: 75.1% vs. 51.1%; p Patients with TTS receiving APT at discharge presented better prognosis up to two-years of follow-up compared with their counterparts not receiving APT
Short- and Long-Term Prognostic Relevance of Cardiogenic Shock in Takotsubo Syndrome: Results From the RETAKO Registry.
This study sought to describe the incidence, determinants, and prognostic impact of cardiogenic shock (CS) in takotsubo syndrome (TTS). TTS can be associated with severe hemodynamic instability. The prognostic implication of CS has not been well characterized in large studies of TTS. We analyzed patients with a definitive TTS diagnosis (modified Mayo criteria) who were recruited for the National RETAKO (Registry on Takotsubo Syndrome) trial from 2003 to 2016. Cox and competing risk regression models were used to identify factors associated with mortality and recurrences. A total of 711 patients were included, 81 (11.4%) of whom developed CS. Male sex, QTc interval prolongation, lower left ventricular ejection fraction at admission, physical triggers, and presence of "a significant" left intraventricular pressure gradient, were associated with CS (C index = 0.85). In-hospital complication rates, including mortality, were significantly higher in patients with CS. Over a median follow-up of 284 days (interquartile range: 94 to 929 days), CS was the strongest independent predictor of long-term, all-cause mortality (hazard ratio [HR]: 5.38; 95% confidence interval [CI]: 2.60 to 8.38); cardiovascular (CV) death (sub-HR: 4.29; 95% CI: 2.40 to 21.2), and non-CV death (sub-HR: 3.34; 95% CI: 1.70 to 6.53), whereas no significant difference in the recurrence rate was observed between groups (sub-HR: 0.76; 95% CI: 0.10 to 5.95). Among patients with CS, those who received beta-blockers at hospital discharge experienced lower 1-year mortality compared with those who did not receive a beta-blocker (HR: 0.52; 95% CI: 0.44 to 0.79; pinteraction = 0.043). CS is not uncommon and is associated with worse short- and long-term prognosis in TTS. CS complicating TTS may constitute a marker of underlying disease severity and could identify a masked heart failure phenotype with increased vulnerability to catecholamine-mediated myocardial stunning
