Clinical implications of cytokines in the critical-care unit.
To understand the role of different cytokines in the pathophysiology and management of different acute cardiovascular disorders in critically ill patients, we reviewed most of the pertinent articles published on Medline, Scopus and EBSCO host research databases from 1985 to January 2009. We used the indexing terms 'cytokines', 'cardiovascular', 'sepsis', 'critical care', 'myocardial dysfunction', 'shock', 'thromboembolism', 'inflammatory' and 'arrhythmias'. Myocardial dysfunction, dysrhythmic and thromboembolic disorders all appear associated with important fluctuations in cytokines. When and how to sample cytokine levels and the ways in which cytokines contribute to patient deterioration or improvement require further clinical studies. The measurement and interplay of several different cytokines may ultimately be of substantial clinical importance in the diagnosis, treatment and prognosis of patients with different acute cardiovascular disorders managed by critical-care physicians in intensive-care units. Although the role of cytokines in cardiovascular disorders is debatable, the clinical implication of cytokines in the critical-care unit is a new horizon that warrants more attention.
