Cardiotoxicity in low-to-moderate cardiovascular risk patients undergoing anti-HER2 therapy: a prospective cardiac magnetic resonance study.

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
backgroundThe study aimed to investigate cardiotoxicity among individuals undergoing anti-human epidermal growth factor receptor 2 (HER2) therapy with a low-to-moderate risk of cardiovascular complications. Cardiac magnetic resonance (CMR) imaging was employed in the investigation. PATIENTS AND
methodsHER2-positive breast cancer patients who underwent CMR examinations both before and during therapy (first follow-up: 3-5 months; second follow-up: 6-12 months) between January 2021 and December 2022 were prospectively included. Each patient was evaluated for the risk of cardiovascular toxicity.
resultsThirty-five HER2-positive breast cancer patients were included (48.86 ± 10.34 years). Eighty-nine percent of patients had low cardiovascular toxicity risk, and 11% had moderate cardiovascular toxicity risk. At follow-up CMR, nine (25.71%) patients developed cardiac dysfunction. At follow-up 1, there was a notable decrease in left ventricular ejection fraction, stroke volume index, cardiac output index, and absolute strain values, accompanied by higher T1 and T2 values as well as end-systolic volume index compared to baseline (p ≤ 0.002). At follow-up 2, the T1 and T2 values recovered to near baseline. The cardiac output index exhibited a continuous decline (p ≤ 0.022), while other variables were similar (p > 0.05). Furthermore, at follow-up 1, the T1 value displayed a marked increase in patients with 1-3 points in cardiovascular toxicity risk factors compared to those with no risk factors (p ≤ 0.043).
conclusionsIt is common for patients with low-to-moderate cardiovascular risk to experience early cardiotoxicity during anti-HER2 therapy. T1 mapping was a valuable approach for quantifying the specific extent of subtle tissue damage.
