Racial and Ethnic Disparities in In-Hospital Outcomes of Takotsubo Cardiomyopathy in the United States.
Article in Journal of racial and ethnic health disparities, 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
backgroundRacial disparities in outcomes among patients with Takotsubo cardiomyopathy (TCM) remain poorly characterized. While TCM is traditionally considered a reversible condition, emerging evidence suggests substantial variation in severity, complications, and resource utilization across racial groups.
objectivesTo evaluate racial and ethnic differences in the primary outcomes of in-hospital mortality and cardiogenic shock among adults hospitalized with TCM, and to assess secondary complications and resource utilization.
methodsWe conducted a retrospective analysis of the National Inpatient Sample (2016–2022) that included adults hospitalized with TCM. Survey-weighted descriptive statistics were used to compare clinical characteristics across White, Black, Hispanic, and Asian populations. Primary outcomes were in-hospital mortality and cardiogenic shock. Survey-weighted multivariable logistic regression adjusted for demographic, clinical, and hospital characteristics estimated adjusted odds ratios (aOR) with 95% confidence intervals (CIs), using White patients as the reference group.
resultsAmong 289,545 weighted TCM hospitalizations, 77.3% were White, 8.2% Black, 6.3% Hispanic, and 2.1% Asian. Compared with White patients, Asian patients had higher adjusted odds of in-hospital mortality (aOR 1.47, 95% CI 1.22–1.77), cardiogenic shock (aOR 1.42, 95% CI 1.17–1.71), and invasive mechanical ventilation (aOR 2.18, 95% CI 1.42–3.35). Black patients had higher adjusted odds of acute kidney injury (aOR 1.40, 95% CI 1.30–1.52) and cardiac arrest (aOR 1.34, 95% CI 1.17–1.54). Hispanic patients had lower odds of atrial fibrillation (aOR 0.62, 95% CI 0.56–0.69) and ventricular arrhythmias (aOR 0.77, 95% CI 0.66–0.89). Length of stay and total hospital charges were significantly higher in Asian and Black patients.
conclusionsRacial and ethnic differences were observed in the primary outcomes of in-hospital mortality and cardiogenic shock, with Asian patients demonstrating the highest adjusted odds of both. Asian and Black patients demonstrate disproportionate risks of hemodynamic instability, critical illness, and resource utilization. These findings underscore the importance of targeted clinical awareness and investigation into the biological, structural, and socioeconomic factors that contribute to inequities in TCM outcomes.
