Vascular leakage following cardiopulmonary bypass contributes to morbidity. Angiopoietin-1 and -2 are biomarkers of endothelial dysfunction. Our aim was to characterize Ang-1 and -2 association with clinical characteristics and outcomes.
Observational cohort study measuring Ang-1/-2 with a panel of cytokines in adults undergoing cardiopulmonary bypass.
Ang-2 levels increased immediately postop whereas Ang-1 levels decreased over time. No significant correlation was found with other inflammatory mediators. High correlation was found between the hospital length of stay and Ang-2 increase at 24 h (rho = 0.590; p < 0.0001). The predictors of Ang-2 increase were female gender, cross clamp time, transfusion of blood and absence of angiotensin-converting enzyme inhibitor as a pre-op medication.
Angiopoietins can detect vascular leakage early and could impact patient's management to decrease length of stay after cardiac surgery.
体外循环后的血管渗漏会导致发病。血管生成素-1和-2是内皮功能障碍的生物标志物。我们的目的是明确血管生成素-1和-2与临床特征及预后的关联。
在接受体外循环的成人中进行观察性队列研究，同时检测血管生成素-1/-2及一组细胞因子。
术后即刻血管生成素-2水平升高，而血管生成素-1水平随时间下降。未发现其与其他炎症介质有显著相关性。住院时间与术后24小时血管生成素-2升高之间存在高度相关性（rho = 0.590；p < 0.0001）。血管生成素-2升高的预测因素为女性、主动脉阻断时间、输血以及术前未使用血管紧张素转换酶抑制剂。
血管生成素能够早期检测血管渗漏，并可能影响患者管理，以缩短心脏手术后的住院时间。
