Myopericarditis After Combined Idarubicin and Quizartinib in FLT3-ITD-Positive AML.
Article in JACC. Case reports, 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 key components of induction therapy for acute myelogenous leukemia with well-understood cardiotoxicity. Quizartinib inhibits FLT3 and has been shown to potentiate apoptosis and promote maladaptive remodeling after myocardial infarction in mice; however, the impact of FLT3 inhibition on a heart already exposed to anthracyclines is poorly understood. CASE SUMMARY: A 64-year-old man with acute myelogenous leukemia developed fever, hypotension, troponin I elevation, and diffuse ST-segment elevation after treatment with cytarabine and idarubicin followed by quizartinib. Cardiac magnetic resonance imaging showed late gadolinium enhancement consistent with myopericarditis and a new reduced left ventricular ejection fraction. Quizartinib was stopped, and the patient received colchicine and guideline-directed medical therapy. Quizartinib was successfully reintroduced at a lower dose without recurrence of cardiac injury. DISCUSSION: This case illustrates a "two-hit" mechanism resulting in acute myopericarditis. The reversibility of the injury and the successful rechallenge emphasize the potential role of dose modification and close monitoring when combining targeted therapies with anthracyclines. TAKE-HOME MESSAGES: Drug-induced myopericarditis should be suspected when cardiotoxic agents are administered sequentially. Rechallenge with a reduced dose may be feasible.
