Clinical efficacy of amiodarone in prehospital emergency treatment of myocardial infarction: a systematic review and meta-analysis.
Synthesis in Journal of cardiothoracic surgery, 2025. 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
objectiveTo systematically review the clinical efficacy of amiodarone in the treatment of myocardial infarction in prehospital emergency.
methodsArticles related to the use of amiodarone in prehospital emergency treatment of myocardial infarction were retrieved from PubMed, Cochrane Library, EMBASE, Wanfang, VIP and CNKI databases, and the retrieval time was from the establishment of the database to October 31 2024. Meta-analysis and risk bias evaluation were carried out with R 4.2.2 software, and the results were considered statistically significant when P < 0.05.
resultsA total of 16 studies involving 832 patients receiving prehospital amiodarone and 800 control patients were included in this systematic review and meta-analysis. Pooled results demonstrated that, compared to the control group, amiodarone significantly reduced the incidence of malignant arrhythmia (RR = 0.29, 95% CI: 0.22 to 0.37, P < 0.01), decreased the average number of defibrillations (MD = -2.40, 95% CI: -2.61 to -2.19, P < 0.01), improved the success rate of rescue (RR = 1.16, 95% CI: 1.12 to 1.21, P < 0.01), lowered the recurrence rate of myocardial infarction (RR = 0.22, 95% CI: 0.13 to 0.35, P < 0.01), reduced the incidence of adverse reactions (RR = 0.33, 95% CI: 0.12 to 0.87, P = 0.02), and shortened the length of hospital stay (MD = -3.81, 95% CI: -4.02 to -3.59, P < 0.01).
conclusionThis systematic review and meta-analysis demonstrated that prehospital amiodarone administration in patients with myocardial infarction significantly reduced the incidence of malignant arrhythmia and the average number of defibrillations, while improving the success rate of rescue. Furthermore, it lowered the incidence of adverse reactions, the recurrence rate of myocardial infarction, and shortened the length of hospital stay. These findings support the clinical promotion of amiodarone in prehospital emergency care for myocardial infarction.
