RESUMO

AIMS: The aim of this study was to investigate the long-term outcome of takotsubo syndrome (TTS) patients with and without hypertension (HT) and to evaluate the effectiveness of treatment with beta-blockers (BBs) and/or renin-angiotensin-aldosterone system inhibitors (RAASi). METHODS AND RESULTS: The study population includes a register-based, multicentre cohort of consecutive patients with TTS, divided into two groups according to the history of HT. Further stratification was performed for BB/RAASi prescription at discharge. The primary outcome was the composite of all-cause death and TTS recurrence at the longest available follow-up. The propensity score weighting technique was used to account for potential confounding. In the overall population (903 patients, mean age 70 ± 11 years), HT was reported in 66% of cases. At a median 2-year follow-up, there was no difference in the risk of the primary composite outcome between patients with and without HT. The adjusted Cox regression analysis showed a significantly lower risk for the primary outcome [adjusted hazard ratio (aHR): 0.69; 95% confidence interval (CI): 0.49-0.99] in patients who received BB vs. those who did not. Renin-angiotensin-aldosterone system inhibitors treatment was not associated with the primary study outcome. The lower risk for the primary outcome with BB treatment was confirmed in patients with HT (aHR: 0.37; 95% CI: 0.24-0.56) but not in patients without (aHR: 1.83; 95% CI: 0.92-3.64; Pinteraction < 0.001). CONCLUSION: In this TTS study, HT did not affect the long-term risk of adverse events but increased the probability of benefit from BB treatment after discharge. Owing to the favourable outcome impact of BB prescription in TTS patients with HT, a tailored pharmacological therapy should be considered in this cohort.


Although not associated with clinical outcomes, hypertension (HT) seems to modify the long-term effectiveness of pharmacological treatment in patients with takotsubo syndrome (TTS). Beta-blockers improved the overall survival of TTS patients with HT and should be considered as first-line therapy in this patient population. The effectiveness of renin­angiotensin­aldosterone system inhibitors on long-term outcome was not significant regardless of the history of HT.
