Prognostic Impact of Right Ventricular Diastolic Dysfunction in Patients Undergoing Isolated Coronary Artery Bypass Grafting.
Observational study in Archives of Iranian medicine, 2025. 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
backgroundRight ventricular diastolic dysfunction (RVDD) increases the volume load on the right ventricle. We aimed to evaluate the association of RVDD with perioperative outcomes in patients undergoing isolated coronary artery bypass graft surgery (CABG).
methodsThis single-center observational study included all consecutive isolated CABG patients with a left ventricular ejection fraction (LVEF)>40% from May 2022 to May 2023 who were evaluated for RV diastolic function by transthoracic echocardiography. We divided patients into two groups, with and without RVDD, and then compared the two groups in terms of the primary outcomes of the duration of hospitalization, intensive care unit (ICU) stay, and intubation time, and the secondary outcome composed of postoperative in-hospital complications.
resultsOur study found that 49.1% of patients suffered from RVDD, and patients with RVDD had significantly lower systolic blood pressure and were more likely to take angiotensin-converting enzyme inhibitors than those without RVDD. There was no association between RVDD and primary outcomes of hospitalization time (β=-0.01; 95% CI -0.05, 0.04;
conclusionPreexisting RVDD in CABG patients with LVEF>40% increased postoperative complications but not significantly. More extensive studies are needed to evaluate RV diastolic function before cardiac surgery to identify high-risk patients and optimize their perioperative management.
