Pressure-strain loop evaluation of myocardial work in patients with coronary artery disease and preserved left ventricular ejection fraction: a retrospective study based on propensity score matching.
Article in European journal of medical research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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 quantify left ventricular function changes in stable coronary artery disease (SCAD) patients with preserved left ventricular ejection fraction using left ventricular pressure-strain loop (LV-PSL) technology. And to evaluate the independent correlation between myocardial work (MW) parameters and SYNTAX score.
methodsWe enrolled 126 patients with suspected SCAD. Forty-five had significant stenosis (SYNTAX score calculated). Seventy-two without significant stenosis served as controls. LV-PSL provided global longitudinal strain (GLS) and MW parameters Including global constructive work (GCW), global wasted work (GWW), global work efficiency (GWE), global work index (GWI) Propensity score matching balanced baseline characteristics. We used paired t-tests, Wilcoxon signed-rank tests, and chi-square tests for group comparisons. Correlation analysis assessed links between SYNTAX scores and GLS/MW parameters. Receiver Operating Characteristic (ROC) curve analysis determined diagnostic performance.
resultsForty-two patient pairs were successfully matched. Significant differences (P < 0.05) were found in GLS and MW parameters between SCAD patients and controls. SCAD patients exhibited lower GCW, GWI, and GWE compared to controls (P < 0.05). Correlation analysis revealed moderate positive correlations between SYNTAX scores and GWW, and moderate negative correlations with GCW. Strong negative correlations were observed between the SYNTAX score and GWE, GWI, and GLS (P < 0.01). ROC analysis identified GWI as a strong SCAD predictor (AUC = 0.713).
conclusionLV-PSL technology effectively monitors left ventricular function and assesses disease severity in SCAD patients, offering practical guidance for clinical decision-making.
