Abstract
Objective To investigate the relationship between plasma N-terminal B-type natriuretic peptide precursor (NT-proBNP), hypersensitive C-reactive protein (hs-CRP), troponin Ⅰ (cTnⅠ) and carbohydrate antigen 125 (CA125) and cardiac function in patients with acute heart failure. Methods From May 2017 to May 2019, 97 patients with acute heart failure admitted to Hangzhou Dajiangdong Hospital were selected as the observation group.According to the cardiac function classification of New York Heart Association (NYHA), 29 patients were classified as grade Ⅱ group, 51 patients as grade Ⅲ group and 17 patients as grade Ⅳ group.Fifty healthy people were selected as control group.The changes of plasma NT-proBNP, hs-CRP, cTnⅠ and CA125 levels, left ventricular end-diastolic diameter (LVEDD) and left ventricular ejection fraction (LVEF) were compared between the two groups.The changes of plasma NT-proBNP, hs-CRP, cTnⅠ and CA125 levels, as well as the changes of LVED and LVEF in the different heart function grading group were compared.The correlation between plasma NT-proBNP, hs-CRP, cTnⅠ, CA125 and LVEDD, LVEF was analyzed. Results The plasma NT-proBNP[(5 684.21±174.39)ng/L], hs-CRP[(16.54±3.27)mg/L], cTnⅠ[(0.43±0.13)g/L] and CA125[(83.24±15.46)U/mL] in the observation group were higher than those in the control group(t=216.813, 25.684, 19.432, 34.138, all P<0.05). The LVEDD in the observation group[(63.21±4.87)mm] was higher than that in the control group[(48.97±2.41)mm], and the LVEFin the observation group[(39.27±3.25)%] was lower than that in the control group[(62.87±4.36)%], the differences were statistically significant (t=19.461, 37.008, all P<0.05). The levels of NT-proBNP[(7 368.18±201.05)ng/L], hs-CRP[(24.19±4.18)mg/L], cTnⅠ[(0.63±0.14)μg/L] and CA125[(164.52±27.48)U/mL] in the grade Ⅳ group were higher than those in the grade Ⅱ group and grade Ⅲ group(grade Ⅲ group: t=31.109, 6.557, 5.321, 13.017; grade Ⅱ group: t=75.873, 16.582, 11.755, 23.178, all P<0.05). The plasma NT-proBNP[(5 751.42±180.34)ng/L], hs-CRP[(15.98±4.56)mg/L], cTnⅠ[(0.41±0.15)g/L] and CA125[(87.97±18.45)U/mL] in the grade Ⅲ group were higher than those in the grade Ⅱ group[(3 481.34±145.26)ng/L, (8.23±2.37)mg/L, (0.25±0.08)μg/L and (28.43±12.21)U/mL](t=57.893, 8.507, 5.320, 15.530, all P<0.05). The LVEDD[(67.95±5.15)mm] in the grade Ⅳ group was higher than that in the grade Ⅱ group and grade Ⅲ group(grade Ⅲ group: t=3.553, grade Ⅱ group: t=8.157, P<0.05), while the LVEF[(34.28±2.36)%] in the grade Ⅳ group was lower than that in the grade Ⅱ group and grade Ⅲ group(grade Ⅲ group: t=6.673, grade Ⅱ group: t=10.417, all P<0.05). The LVEDD[(62.78±5.21)mm] in the grade Ⅲ group was higher than that in the grade Ⅱ group[(57.87±3.25)mm](t=4.586, P<0.05), while the LVEF in the grade Ⅲ group[(39.98±3.24)%] was lower than that in the grade Ⅱ group[(45.98±4.25)%](t=7.097, P<0.05). LVEDD was positively correlated with NT-proBNP, hs-CRP, cTnⅠ and CA125, while LVEF was negatively correlated with NT-proBNP, hs-CRP, cTnⅠ and CA125. Conclusion The levels of NT-proBNP, hs-CRP, cTnⅠ and CA125 in plasma of patients with acute heart failure are elevated, and they are significantly correlated with cardiac function grading and cardiac function indicators.
