Abstract: Objective To study the clinical significance of cardiac injury biomarkers(CK-MB and cTnI) and pro-brain natriuretic peptide(proBNP) joint detection for prognosis value in Elderly sepsis. Methods Sixty elderly patients with sepsis were selected. According to the severity of disease divided into general and severe sepsis group.Meanwhile, 30 healthy volunteers as a control group. Comparative study of plasma proBNP, cTnI, CK-MB levels and acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) in three groups;and the correlation analysis of the indicators. Results Compared with control group, the plasma levels of proBNP and cTnI were significantly higher in patients with sepsis; And the APACHEⅡ score in the severe sepsis group was significantly higher than the general sepsis group (P<0. 05). The plasma proBNP, cTnI, CK-MB level and APACHE Ⅱ scores in death group were significantly higher than the survival group (P<0. 05). The proBNP plasma levels, cTnⅠ and CK-MB levels in severe sepsis patients were positively correlated (P<0. 05); They were positively correlated between ProBNP level, cTnⅠ level and the APACHEⅡ score(P<0. 05). Conclusions ProBNP plasma levels and cTnⅠ can effectively reflect the extent of the cardiac damage in elderly sepsis; Early plasma proBNP level, cTnI and CK-MB combined detection of elderly sepsis may have important clinical significance.
