| Abstract: | Objective To study the correlation of serum monoamine oxidase (MAO) and interleukin-6 (IL-6) levels with cardiac function classifications in chronic renal failure patients with heart failure. Methods 80 chronic renal failure patients with heart failure treated from June 2021 to May 2022 in Nephrology and Dialysis Department of Handan Mingren Hospital were chosen as experimental group. According to New York Heart Association (NYHA), the experimental group was assigned to grade I group (20 cases), grade II group (20 cases), grade III group (20 cases) and grade IV group (20 cases). Over the same time period, 80 chronic renal failure patients were set as control group A. 80 healthy checkups were set as control group B. Serum MAO, IL-6 and N-terminal pro-brain natriuretic peptide (NT-proBNP) levels were measured, and analyze its correlations with cardiac function classifications. Among them, the test group and the control group A met the disease diagnostic criteria; were confirmed by various examinutions, and were in a stable comdition, and did not receive treatment before the experiment. In addition, all the observation objects signed a love letter with their familes receive the therapy; the research subjects and their family members had signed the informed consent forms. Results Serum MAO(8.56±1.85U/L), IL-6(128.56±17.48ng/L ) and NT-proBNP (872.04±11.25pg/ml) levels in the experimental group were, and which were significantly higher than those of control group A (3.14±1.01U/L, 97.42±12.36ng/L, 195.79±6.87pg/ml)]and control group B (2.87±0.85U/L, 77.69±8.15ng/L, 66.04±5.48pg/ml)]，the differences were statistically significant（F=478.790，300.850，220 577.310，all P ＜ 0.05）. Serum MAO, IL-6 and NT-proBNP levels in grade I group were 3.77±1.05U/L, 104.26±15.47ng/L and 381.25±8.44pg/ml， respectively. Serum MAO, IL-6 and NT-proBNP levels in grade II group were 5.26±1.35U/L, 113.15±16.89ng/L and 579.31±10.10pg/ml，respectively. Serum MAO,IL-6 and NT-proBNP levels in grade III group were 7.48±2.09U/L, 125.73±17.02ng/L and 782.08±11.24pg/ml，respectively. Serum MAO, IL-6 and NT-proBNP levels in grade IV group were 8.99±2.67U/L, 130.58±17.96ng/L and 901.54±12.10 pg/ml，respectively. Serum MAO, IL-6 and NT-proBNP levels in grade IV group were significantly higher than grade I group, grade II group and grade III group （F=29.750，172.220，9 414.430, all P ＜ 0.05）. The diagnosis sensitivity（97.50%）, specificity（95.00%） and area under ROC（0.893） curve based on combined examination were higher than those based on MAO（86.25%，83.75%，0.600） or IL-6（87.50%，83.75%，0.580）, the differences were statistically significant（χ2=0.004，7.207，6.664，all P ＜ 0.05）.Serum MAO, IL-6 and NT-proBNP levels were positively correlated with cardiac function classifications for chronic renal failure patients with heart failure (r=0.562 ～ 0.781，all P ＜ 0.05). Conclusion Serum MAO and IL-6 levels were closely correlated with cardiac function classifications in chronic renal failure patients with heart failure, which can make for disease diagnosis and evaluate the cardiac function classifications; the diagnosis sensitivity and specificity based on combined examination are higher than single examination. |
