Echocardiographic Alterations in Subjects with Sarcopenia and Right Heart Failure.
Article in Medical sciences (Basel, Switzerland), 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
backgroundChronic heart failure (HF) is a significant public health issue. The principal risk factors for left ventricular diastolic dysfunction (LVDD) include older age, female sex, obesity, hypertension, smoking, and diabetes, among others, all of which can reduce physical activity. Additionally, peripheral factors such as skeletal muscle mass (SMM) abnormalities decrease maximal oxygen consumption. In elderly HF patients, the prevalence of sarcopenia is higher than in those without HF; however, the relationship between sarcopenia and HF remains insufficiently explained, particularly in right HF (RHF). Our objective was to describe the echocardiographic alterations between sarcopenic and non-sarcopenic subjects with RHF.
methodsA cross-sectional study was conducted. Outpatients aged 18 years or older with a confirmed diagnosis of RHF were included. Sarcopenia was defined according to EWGSOP2.
resultsA total of 183 patients were included; 24.5% had sarcopenia. The mean age was 64.34 ± 13.97 years. Echocardiographic characteristics revealed evidence of LVDD in sarcopenic subjects, as indicated by lower E wave velocity, E/A ratio, and e' lateral and medial values, as well as lower right ventricular (RV) wall thickness compared with non-sarcopenic subjects. The multivariate model showed that sarcopenia subjects had lower RV wall thickness (B: -1.36 mm, 95% CI: -2.30 to -0.42), e' medial (B: -1 cm/s, 95% CI: -1.99 to -0.02), and e' lateral (B: -1.78 cm/s, 95% CI: -2.97 to -0.60).
conclusionsThe prevalence of sarcopenia in RHF patients was 24.6%, which was associated with LVDD and lower RV wall thickness, suggesting a loss of cardiac muscle mass.
