Assessment of the Impact of Dexmedetomidine on Myocardial Injury in TAVI Patients: A Retrospective Cohort Study Utilizing PSM-DID.

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
Background: Transcatheter Aortic Valve Implantation (TAVI) is a minimally invasive procedure for treating severe aortic valve diseases but can lead to perioperative myocardial damage (PMD). Dexmedetomidine (DEX), an α2-adrenergic receptor agonist, has shown potential to reduce myocardial injury in other cardiac procedures. This effect is attributed to its anti-inflammatory properties, which help reduce the inflammatory response associated with myocardial damage, and its antioxidant properties, which combat oxidative stress that contributes to cell injury. But its effectiveness during TAVI remains unclear. Objective: To assess the impact of DEX on myocardial injury in patients undergoing TAVI under general anesthesia. Methods: A retrospective cohort study of 159 patients (after exclusions) who underwent TAVI from January 2022 to August 2024. Patients were divided into DEX and control groups. Primary outcomes were peak levels of cardiac troponin I and CK-MB within 48 hours postoperatively. Secondary outcomes included IL-6, PCT, and NT-proBNP levels. Propensity score matching (PSM) and Differences-in-Differences (DID) method were used for analysis. Results: After PSM, the DEX group exhibited significantly lower peak values of troponin I (P < 0.001) and CK-MB (P < 0.001) compared to the control group, indicating reduced myocardial injury. No significant differences were observed in IL-6, PCT, and NT-proBNP levels between the groups. The DID analysis suggested a negative correlation between DEX use and major adverse postoperative events, highlighting DEX as a potential protective factor. Conclusion: Dexmedetomidine administration during TAVI was associated with reduced levels of myocardial injury markers, indicating a potential cardioprotective role. By reducing myocardial injury, DEX may contribute to improved perioperative outcomes, including a decreased risk of major adverse postoperative events. These results highlight the potential clinical utility of DEX in the perioperative management of TAVI patients, suggesting that its inclusion in anesthetic protocols could enhance patient care and recovery.
