AbstractThis study aimed to explore the organ-protective effects of dexmedetomidine in patients with sepsis combined with myocardial injury. From December 2021 to December 2023, 263 sepsis patients with myocardial injury were included based on inclusion and exclusion criteria. They were divided into an experimental group (n = 122), who had previously received dexmedetomidine, and a control group (n = 141), who had received midazolam. After matching baseline characteristics, the treatment outcomes between the 2 groups were compared. In a propensity score-matched cohort of 263 patients, each group had 62 individuals with balanced baseline characteristics. The experimental group showed significantly lower heart rates on days 1, 3, and 7 compared to the control (P < .05). Biomarkers high-sensitivity troponin I and creatine kinase-MB decreased significantly by days 3 and 7, with lower levels in the experimental group. B-type natriuretic peptide levels were also lower in the experimental group on days 3 and 7. Heart function improved in both groups, with the experimental group showing better outcomes. Inflammatory markers decreased significantly after 7 days, with the experimental group having lower levels. Hospitalization duration was similar between groups. Dexmedetomidine reduces heart rate and inflammatory markers, protects myocardial cells, and improves cardiac function in patients with sepsis and myocardial injury. It shows potential as a treatment option, with future research needed to assess its long-term efficacy and safety.Copyright © 2024 the Author(s). Published by Wolters Kluwer Health, Inc.
