Preoperative Right Ventricular Tei Index as a High-Risk Marker for Adverse Outcomes in Patients Undergoing Cardiac Surgery.

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
purposeCardiovascular surgery entails considerable risk because of its complexity and the frequency of perioperative complications. The right ventricular Tei index (RV-TI) provides an integrated measure of ventricular performance, encompassing systolic and diastolic function. Although not widely applied in this setting, its role as a predictor of outcomes is promising. This study evaluated the utility of RV-TI in predicting postoperative complications in patients undergoing diverse cardiovascular surgeries, emphasizing its value for surgical risk stratification and patient management.
methodsA single-center, cross-sectional study was conducted at the National Institute of Cardiology Ignacio Chávez, Mexico City, including 195 adults who underwent cardiac surgery between June 2022 and April 2023. RV-TI was obtained by transthoracic tissue Doppler, using 0.53 as the abnormal cutoff. One hundred and forty-nine patients had normal RV-TI values, while 46 were classified as abnormal.
resultsAbnormal RV-TI correlated with diabetes mellitus, advanced age, and vasoplegic syndrome. These patients experienced higher in-hospital mortality and more severe complications, including the need for renal replacement therapy, pneumonia, delirium, and greater transfusion requirements.
conclusionRV-TI appears to be a valuable adjunct in preoperative risk assessment for cardiac surgery. Its incorporation into clinical practice could improve patient selection and decision-making, contributing to better surgical outcomes.
