Objectives: The aim of this study was to evaluate the efficiency of ischemia-modified albumin (IMA) for predicting major adverse cardiovascular events (MACE) in continuous ambulatory peritoneal dialysis (CAPD) patients.
Design and methods: A prospective observational study was conducted with 120 CAPD patients and 37 healthy volunteers. Demographic and clinical data were collected. The primary end point is the occurrence of MACE.
Results: A total of 157 participants with a mean age of 43.64 years finally completed this study. The CAPD patients had a significantly high rate of MACE (P=0.001) and high levels of IMA than healthy controls (P<0.001). Compared with CAPD patients with normal levels of IMA, the CAPD patients with high levels of IMA (>85 kU/L) had lower non-MACE survival rate (P<0.001), which indicated that the high IMA CAPD patients may suffer a high rate of MACE. In addition, the high IMA CAPD patients also had a low level of serum albumin (P<0.001) and hemoglobin (P=0.018). The correlation analysis showed that the serum albumin level was the most effective factor influencing IMA (B=-0.967, P<0.001).
Conclusions: CAPD patients with high levels of IMA had a high incidence rate of MACE. IMA was a good predictive marker of MACE and might be important in cardiovascular risk stratification of CAPD patients.
