Value of Brain Natriuretic Peptide and Heart Failure Ultrasound in the Diagnosis of Early Chronic Heart Failure / 医学研究杂志

ABSTRACT

Objective To investigate the value of brain natriuretic peptide and heart failure ultrasound in the diagnosis of early chronic heart failure.Methods One hundred and forty-six patients with chronic heart failure and seventy-five healthy people with normal heart function were involved.According to NYHA classification,patients with chronic heart failure were divided into grade Ⅰ,Ⅱ,Ⅲ and Ⅳ,including grade Ⅰ twenty six,grade Ⅱ forty three,grade Ⅲ forty eight and grade Ⅳ twenty nine patients.Results There was no significant difference in the general information between patients with chronic heart failure and healthy people with normal heart function (P ＞ 0.05),including age,sex,ALT,AST,fasting blood glucose,total cholesterol,triglyceride,serum creatinine and CRP.The BNP of the two groups were compared,and we found the BNP of grade Ⅱ (181.19 ±48.06),Ⅲ (279.26 ±49.45) and Ⅳ (882.34 ± 388.71) patients was significantly higher than healthy people (54.12 ± 25.87),and with the severity of heart failure,BNP increased gradually.There was statistically significant the difference (P ＜ 0.05).but there was no significant difference between the patients of grade Ⅰ (77.14 ± 24.32) and healthy people (P ＞ 0.05).Compared with healthy people(0.78 ± 0.42),HFEI was significantly higher in patients with chronic heart failure.The HFEI of grade Ⅰ (1.58 ± 0.89),Ⅱ (2.64 ± 1.07),Ⅲ (4.47 ± 1.39) and Ⅳ (6.33 ± 1.61) were compared,we found HFEI increased gradually with the severity of heart failure,and the difference was statistically significant (P ＜ 0.05).From the analysis between BNP and HFEI,we found that BNP was significantly positively correlated with HFEI in patients with chronic heart failure (r =0.935,P =0.000).From ROC curve analysis,the area under the ROC curve of early chronic heart failure was 0.970,showing that plasma BNP combined with HFEI could be accurately diagnosed early chronic heart failure.Conclusion We find plasma brain natriuretic peptide and heart failure echocardiography index can be used in early diagnosis of chronic heart failure.
