Abstract
OBJECTIVE: To investigate the correlation between the levels of urine calcium integrin binding protein-1 (CIB1) and serum precursor N-terminal brain natriuretic peptide (pro-BNP) and ischemic heart failure. PATIENTS AND METHODS: 30 patients diagnosed as acute ischemic heart failure for the first time in our hospital from January to August 2016 were continuously selected as the observation group 1, 30 patients with chronic stable ischemic heart failure as the observation group 2, and 30 healthy volunteers as the control group. Urine CIB1 level was detected via enzyme linked immunosorbent assay (ELISA) and serum pro-BNP level was detected via radioimmunoassay. The linear correlation between the CIB1 and pro-BNP levels in observation group 1 was observed, and the diagnostic value of CIB1 and pro-BNP levels for chronic stable ischemic heart failure were analyzed using the receiver operating characteristic (ROC) curve. RESULTS: CIB1 and pro-BNP levels in the observation group 1 were significantly higher than those in the observation group 2. These levels were significantly lower in the control group (p < 0.05). In the observation group 1, CIB1 and pro-BNP levels were positively correlated (p < 0.05). The diagnostic accuracy of CIB1 for chronic stable ischemic heart failure in the observation group 2 (area under the curve, AUC) was 0.854, the sensitivity was 86.6% and the specificity was 82.5%, respectively. The diagnostic accuracy of pro-BNP was 0.823, the sensitivity was 83.5% and the specificity was 85.9%, respectively. CONCLUSIONS: There is a significant correlation between the urine CIB1 and serum pro-BNP levels in patients with acute ischemic heart failure. In patients with chronic stable ischemic heart failure, the diagnostic value of urine CIB1 outperforms that of serum pro-BNP, which still needs further study.
