OBJECTIONS: Development of acute lung injury after cardiac surgery is associated with an unfavourable outcome. Acute respiratory distress syndrome in general is, besides cytokine and interleukin activation, associated with activation of platelets, monocytes and neutrophils. In relation to pulmonary outcome after cardiac surgery, leucocyte and platelet activation is described in animal studies only. Therefore, we explored the perioperative time course of platelet and leucocyte activation in cardiac surgery and related these findings to acute lung injury assessed via PaO2/FiO2 (P/F) ratio measurements.
METHODS: A prospective cohort study was performed, including 80 cardiac surgery patients. At five time points, blood samples were directly assessed by flow cytometry. For time course analyses in low (< 200) versus high (≥200) P/F ratio groups, repeated measurement techniques with linear mixed models were used.
RESULTS: Already before the start of the operation, platelet activatability (P = 0.003 for thrombin receptor-activator peptide and P = 0.017 for adenosine diphosphate) was higher, and the expression of neutrophil activation markers was lower (CD18/CD11; P = 0.001, CD62L; P = 0.013) in the low P/F group. After correction for these baseline differences, the peri- and postoperative thrombin receptor-activator peptide-induced thrombocyte activatability was decreased in the low P/F ratio group (P = 0.008), and a changed pattern of neutrophil activation markers was observed.
CONCLUSIONS: Prior to surgery, an upregulated inflammatory state with higher platelet activatability and indications for higher neutrophil turnover were demonstrated in cardiac surgery patients who developed lung injury. It is difficult to distinguish whether these factors are mediators or are also aetiologically related to the development of lung injury after cardiac surgery. Further research is warranted.
