Noninvasive left ventricular myocardial work identifies subclinical myocardial dysfunction in patients with systemic sclerosis.
Article in Clinical rheumatology, 2025. 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
objectiveMyocardial work (MW) is a novel indicator measured by noninvasive echocardiography, which could detect subclinical myocardial dysfunction before reduction of left ventricular ejection fraction (LVEF). The study aimed to evaluate subclinical myocardial dysfunction in patients with systemic sclerosis (SSc) with normal LVEF, using left ventricular MW through two-dimensional speckle-tracking imaging (2D-STI).
methodEighty patients with SSc, which included 40 diffuse skin type SSc (dcSSc) and 40 limited skin type SSc (lcSSc) according to LeRoy's criteria, and 40 gender and age matched health subjects were enrolled. The images were collected using standard transthoracic echocardiography. Global longitudinal strain (GLS), global work index (GWI), global constructive work (GCW), global wasted work (GWW), and global work efficiency (GWE) were obtained.
resultsOur study showed that there were no significant differences in LVEF and GLS between the SSc group and the control group. Both the lcSSc group and the dcSSc group had lower GWI, GCW, and GWE and higher GWW than the control group (P < 0.05). GWI, GCW, and GWE were lower in the dcSSc group than those in the lcSSc group, while GWW was higher in the dcSSc group (P < 0.05). GWI and GCW were positively correlated with LVEF (P < 0.001). GWI, GCW, and GWE were negatively correlated with GLS (P < 0.001), and GWW was positively correlated with GLS (P < 0.05). Elevated CRP was associated with reduced GWI and GCW (P < 0.05).
conclusionsOur study demonstrates the presence of subclinical myocardial dysfunction in SSc patients. The dcSSc patients may be more prone to have subclinical myocardial dysfunction than the lcSSc patients. Noninvasive left ventricular myocardial work may be a promising novel tool for detection of subclinical myocardial dysfunction.
