Given the putative harmful effects of catecholamines in patients with TTS, beta-blockers may potentially decrease the intensity of the detrimental cardiac effects in those patients. Objective The purpose of this study was to assess the impact of beta-blocker therapy on long-term mortality and TTS recurrence. Methods The cohort study used the national Spanish Registry on TakoTsubo Syndrome (RETAKO). A total of 970 TTS post-discharge survivors, without pheochromocytoma, left ventricular outflow tract obstruction, sustained ventricular arrhythmias, and significant bradyarrhythmias, between January 1, 2003, and July 31, 2018, were assessed. Cox regression analysis and inverse probability weighting (IPW) propensity score analysis were used to evaluate the association between beta-blocker therapy and survival free of TTS recurrence. Results From 970 TTS patients, 582 (60.0%) received beta-blockers. During a mean follow-up of 2.5 ± 3.3 years, there were 87 deaths (3.6 per 100 patients/year) and 29 TTS recurrences (1.2 per 100 patient/year). There was no significant difference in follow-up mortality or TTS recurrence in unadjusted and adjusted Cox analysis (hazard ratio [HR] 0.86, 95% confidence interval [CI] 0.59–1.27, and 0.95, 95% CI 0.57–1.13, respectively). After weighting and adjusting by IPW, differences in one-year survival free of TTS recurrence between patients treated and untreated with beta-blockers were not found (average treatment effect −0.01, 95% CI −0.07 to 0.04; p=0.621). Conclusions In this observational nationwide study from Spain, there was no significant association between beta-blocker therapy and follow-up survival free of TTS recurrence.
