Impact of early hyperoxia on 28-day in-hospital mortality in patients with myocardial injury

We included consecutive patients with myocardial injury (cardiac troponin-I ≥ 0.2 ng/mL in the first 24 hours of presentation) who were arrived at our emergency department and admitted to the hospital over 7 years, and evaluated the association between hyperoxia in the first 24 hours and outcomes (28 day mortality and occurrence of organ dysfunction estimated by the SOFA score). The results showed hyperoxia was strongly correlated with unfavorable outcomes.本研究纳入了7年期间就诊于本院急诊科并住院的连续性心肌损伤患者，该类患者的定义为首次就诊后24小时内心肌肌钙蛋白I（cardiac troponin-I）≥0.2 ng/mL；本研究分析了患者就诊后前24小时内的高氧血症与预后之间的关联，预后指标包括28天死亡率及通过序贯器官衰竭评分（SOFA score）评估的器官功能障碍发生情况。研究结果显示，高氧血症与不良预后显著相关。
