Evaluating the Use of Post-Systolic Shortening and Global Longitudinal Strain in Predicting Immediate Postoperative Course after Coronary Artery Bypass Grafting: Prospective Observational Study.
Observational study in Annals of cardiac anaesthesia, 2026. 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
objectiveTo study the use of post-systolic shortening (PSS) and global longitudinal strain (GLS) in predicting immediate postoperative adverse events after coronary artery bypass grafting (CABG).
designA prospective observational study.
settingConducted in a single tertiary care hospital.
participantsA total of 71 patients undergoing elective CABG were included in our study. Our patients were aged between 45 and 75 years and included both off-pump and on-pump cases. We excluded patients with left ventricular function less than 30%, severe diastolic dysfunction, severe right ventricular dysfunction, concomitant more than moderate valve dysfunction, arrhythmias, left or right bundle branch blocks, and unwillingness to participate in the study.
methodsPreoperative echocardiogram included left ventricular post-systolic index (LV PSI) and GLS. Postoperatively, composite adverse events were documented by measuring the vasoactive-inotrope score (VIS) of ≥ 10 at 24 h, total duration of inotropes >40 h, intensive care unit (ICU) stay >7 days, and adverse events like low cardiac output, acute kidney injury, ventilation requirement of >24 h, and any mortality. MEASUREMENTS AND MAIN
resultsLeft ventricular global longitudinal strain (LV GLS) and LV PSI values were analyzed using receiver operating characteristic (ROC) curves, and the area under the curve (AUC) was used to compare the prediction and to derive a cutoff. AUC for LV GLS and LV PSI was 0.92 each and showed good prediction. We got a cutoff of -14.6 for LV GLS and a cutoff of 10.5 for LV PSI.
conclusionWe conclude that GLS and PSI can effectively predict immediate postoperative adverse events effectively in patients undergoing CABG.
