Dynamic changes of cardiac biomarkers levels during hospitalization
All patients were divided into three groups (non-critical group, critical-survivor group and critical-nonsurvivor group to record and compare dynamic changes of cardiac biomarkers. BNP increased rapidly after the 14th day in critical-nonsurvivor group but decreased respectively from the 3th day and 7th day in the non-critical and critical-survivor groups. Levels of hs-cTnI was clearly elevated from the 14th day and rapidly decreased from the 21th day in critical-survivor group and critical-nonsurvivor group, but for non-critical group, it gradually decreased after the peak on the 3th day. Differences among three groups were significant for LDH, CK-MB, HBDH throughout the clinical course. LDH and HBDH increased for all patients in the early stage of illness, then decreased for non-critical and critical survivors but rapidly increased for nonsurvivors in the late stage of illness.
