The prevalence of abnormal right ventricle speckle strain in the setting of acute myocarditis and preserved left ventricle function.
Article in The international journal of cardiovascular imaging, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundAcute myocarditis has a wide spectrum of clinical presentation, from subclinical disease to acute heart failure, and sudden cardiac death. Two-dimensional speckle tracking echocardiography (2D-STE) has been proven effective in early diagnosis of subclinical cardiac injury, however, there is a limited data regarding the right ventricle (RV) involvement among patients with acute myocarditis. PURPOSE: We evaluated the prevalence of early subclinical RV injury assessed by 2D-STE, among patients with acute myocarditis and preserved left ventricle (LV) function.
methodsWe performed a retrospective single-center study at Tel-Aviv Sourasky Medical Center, including all adult patients hospitalized with acute myocarditis, who presented with preserved LV function. 2D-STE analysis of the RV was performed offline, assessing both the RV four-chamber longitudinal strain peak systolic (RV4CLS PK) and the free wall longitudinal strain peak systolic (RVFWLS PK). The myocarditis group was compared to a healthy control group.
resultsFrom 2011 to 2020, a total of 90 patients included in the study and were compared to 70 healthy subjects. RV 2D-STE emerged as significantly lower for both the RV4CLS PK (-21.8 ± 4.2 vs. -24.9 ± 4.8, P < 0.001) and RVFWLS PK (-24.7 ± 4.9 vs. -28.4 ± 5, P < 0.001), and remained significant in a multivariate analysis.
conclusionWe presented for the first time the presence of subclinical RV dysfunction, assessed by 2D-STE, in patients diagnosed with acute myocarditis, in the presence of preserved LV function. Further studies are needed to evaluate its' role in the development of LV dysfunction, heart failure and mortality.
