Another potential etiology for cardiac manifestation after snakebite.
Article in Tropical medicine and health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
This letter discusses the possibility of Takotsubo cardiomyopathy (TTC) as an alternative diagnosis in a recently reported case of acute myocardial infarction following a hump-nosed viper bite. The patient's presentation, including delayed chest tightness, elevated troponin, ECG changes, and normal coronary arteries, coupled with complete recovery within 3 months, strongly suggests TTC. Multiple case reports have documented the association between snakebites and TTC, with proposed pathophysiological mechanisms including sympathetic surge from pain and stress, direct cardiotoxic effects of venom, and inflammatory mediators during envenomation. The excessive catecholamine response may trigger transient cardiac dysfunction characteristic of TTC. Recognizing TTC as a potential complication of snakebites has important clinical implications, as its management and prognosis differ from acute coronary syndrome. Understanding this association may enhance diagnostic approaches and treatment strategies in similar cases, particularly when normal coronary arteries and complete cardiac recovery are observed.
