Levels of Serum IGF-1, HCY, and Plasma BNP in Patients with Chronic Congestive Heart Failure and Their Relationship with Cardiac Function and Short-Term Prognosis.

Abstract

Objective To investigate the levels of serum insulin like growth factor-1 (IGF-1), homocysteine (HCY), and plasma brain natriuretic peptide (BNP) in patients with chronic congestive heart failure (CCHF) and their relationship with cardiac function and short-term prognosis. Methods A total of 95 patients with CCHF admitted to our hospital from October 2017 to December 2018 were selected as the observation group. Patients conform to grade II∼IV of the New York Heart Association (NYHA) heart function class. At the same time, the people with normal physical examination results were selected as a control group. Serum IGF-1, HCY, and plasma BNP levels were detected in the two groups, and left ventricular end-diastolic diameter (LVDd) and left ventricular ejection fraction (LVEF) were detected in the observation group. According to the follow-up results, the observation group was divided into the subgroup with good prognosis and the subgroup with poor prognosis. The relationship between the levels of serum IGF-1, HCY, and plasma BNP among cardiac function and short-term prognosis were analyzed. Results The serum IGF-1 level of the observation group was lower than that of the control group, and the serum HCY and plasma BNP levels were higher than those of the control group (P < 0.05). Serum IGF-1 level in grade III of NYHA was lower than that in grade II, and serum HCY and plasma BNP levels were higher than those in grade II. Serum IGF-1 level in grade IV was lower than that in grade II and grade III, and serum HCY and plasma BNP levels were higher than those in grade II and grade III (P < 0.05). Serum IGF-1 level was negatively correlated with LVDd and positively correlated with LVEF. Serum HCY and plasma BNP levels were positively correlated with LVDd and negatively correlated with LVEF (P < 0.05). There were 42 patients with poor prognoses (44.21%). Serum IGF-1 levels of patients with poor prognosis were lower than those with good prognosis, and serum HCY and plasma BNP levels were higher than those with good prognosis (P < 0.05). Conclusion The serum IGF-1 level in patients with CCHF decreased, and serum HCY and plasma BNP levels increased. Serum IGF-1, HCY, and plasma BNP were correlated with cardiac function and have some clinical value for short-term prognosis.
