Global longitudinal strain decline after anthracyclines in a relatively low-risk Japanese breast cancer cohort.
Article in Heart and vessels, 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
backgroundAnthracyclines are known to exhibit dose-dependent cardiotoxicity, leading to cancer therapy-related cardiac dysfunction (CTRCD). The significance of routine global longitudinal strain (GLS) measurements remains uncertain in patients at low or moderate risk for cardiotoxicity. This study aimed to investigate the appropriateness of the contemporary CTRCD surveillance strategy in this population.
methodsWe prospectively enrolled women with breast cancer undergoing anthracycline-based chemotherapy at Keio University Hospital from April 2018 to November 2023. Cardiotoxicity risk was assessed using the Heart Failure Association-International Cardio-Oncology Society (HFA-ICOS) tool. GLS was measured by echocardiography at baseline (T0), completion of anthracyclines (T1), and 6 months (T2) and 12 months (T3) after initiating chemotherapy. CTRCD was defined as a > 15% relative decline in GLS from baseline. Repeated GLS measurements were analyzed using linear mixed models with post-hoc Tukey testing.
resultsFifty-eight patients (mean age 53.8 ± 9.3 years) were included, with 53 (91.3%) classified as low or moderate risk. GLS significantly declined at T2 and returned toward baseline at T3. GLS-based CTRCD was observed in 4 (6.9%), 14 (24.1%), and 4 (6.9%) patients at T1, T2, and T3, respectively. The majority of CTRCD cases showed spontaneous recovery by T3. Persistent CTRCD at T3 was limited to a small number of patients and was significantly associated with higher high-sensitivity cardiac troponin T levels at T1 (area under curve = 0.836; 95% CI, 0.674-0.997), with a Youden index-derived cutoff of 0.016 ng/mL by receiver operating characteristic analysis.
conclusionsIn breast cancer patients with low to moderate cardiotoxicity risk, early GLS decline following anthracycline exposure was mostly transient. These findings support current surveillance recommendations and suggest a potential role for troponin in identifying patients at risk for persistent dysfunction.
