OBJECTIVE: We studied the diagnostic value of CK-MB and troponin (cTnI) in uremia with acute left ventricular failure patients.
PATIENTS AND METHODS: We enrolled 130 uremia patients with maintenance hemodialysis (MHD) and divided them into two groups: (i) the observation group with patients suffering from acute left ventricular failure (n=30) and (ii) the control group which contained cases without acute left ventricular failure (n=100). We verified CK-MB, cTnI, serum creatinine, blood urea nitrogen, pro-BNP and LVEF levels at 6 h, 12 h, 24 h, 48 h, 72 h, 7 d and 14 d after the attack and carried out 1-year follow-up to compare total mortality and cardiogenic mortality.
RESULTS: Our results showed that CK-MB and cTnI levels in the observation group were significantly higher than those in the control group (p<0.05). CK-MB and cTnI in the observation group increased into platform stage slowly with no peak or downtrend. They were in a linear pattern in the control group. Comparison of SCr and BUN in two groups at different time points produced no statistically significant differences (p>0.05). Pro-BNP levels in the hospital as well as 1 month, 6 months and 12 months follow-ups were higher than those in the control group, and differences were of statistical significant (p<0.05). While in hospital LVEF level in the observation group was higher than that in the other group, differences regarding 1 month, 6 months and 12 months follow-up between two groups had no statistical significance (p>0.05). Total mortality and cardiogenic mortality in the observation group were higher than those in the control group, and differences were statistically significant (p<0.05).
CONCLUSIONS: CK-MB, cTnI, SCr, BUN, pro-BNP and LVEF were independent risk factors for total mortality while CK-MB, cTnI and pro-BNP were independent risk factors for cardiogenic mortality.
