Physical triggers in takotsubo syndrome: a high-risk phenotype? insights from the eVOLUTION registry.
Observational study in European heart journal. Cardiovascular Imaging, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPhysical triggers (PT) are increasingly recognized as important determinants of outcomes in Takotsubo syndrome (TS). This multicenter study investigated the prevalence, clinical features, cardiovascular magnetic resonance (CMR) findings, and prognostic impact of PT in patients with TS. METHODS AND
resultsIn this retrospective registry, 399 TS patients (mean age 70.1 ± 11.8 years, 91% female) were included with a median follow-up of 26.7 months. A PT was identified in 30.5% of cases, an emotional trigger in 38.8%, and no trigger in 30.5%. Patients with PT showed higher C-reactive protein levels (P = 0.008), lower troponin values (P = 0.018), less frequent and less extensive T2-STIR abnormalities (P = 0.007 and P = 0.005, respectively) and LGE (P = 0.002 and P = 0.005, respectively), longer hospital stays (P = 0.002), and more frequent in-hospital complications (P = 0.001). Kaplan-Meier analysis demonstrated significantly lower event-free survival in the PT group compared with patients in the emotional or no-trigger groups (log-rank P = 0.003). In multivariable Cox regression analysis, the presence of a physical trigger (P = 0.037) and pre-existing neurological disease (P = 0.027) were independently associated with a higher risk of all-cause mortality and post-discharge adverse events.
conclusionTS patients with PT represent a high-risk subgroup with worse in-hospital outcomes and increased post-discharge events. Careful identification of the trigger type may therefore help stratify risk, allowing for closer monitoring during hospitalization and more vigilant long-term management in the outpatient setting.
