Abstract

BACKGROUND: This study was conducted to see whether increased values of serum CA125 and BDNF (brain-derived neurotrophic factor) on acute myocardial infarction (AMI) act as predictor for acute heart failure (AHF).

MATERIAL AND METHODS: Seventy-eight patients with clinically diagnosed cardiac function II–IV; and AHF were considered as the study group of this retrospective study and patients who had cardiac function I (without AHF) were considered the control group (n=82). The values of CA125 and BDNF were measured using enzyme-linked immunosorbent assay (ELISA) for developing the correlation with the Killip classification, and the diagnostic value of AHF.

RESULTS: Statistically insignificant difference was noticed between baseline information e.g., blood pressure or smoking status of participants in study group and control group (P>0.05). The higher values of CA125 (5.68±1.8 U/mL or BDNF (19.48±5.3 pg/mL) in the study group had advantage over the control after independent sample t-test (P<0.001). A positive correlation was observed between values of the test substances and Killip classifications (I-IV) of cardiac functioning was observed (r=0.745, P<0.001; Spearman’s rank correlation coefficient). The sensitivity and specificity of area under the curve (AUC) combined with serum CA125 and BDNF levels in the diagnosis of AHF was 91.02% and 81.63%, respectively.

CONCLUSIONS: Increased serum level of the test substances indicates severity of AHF-leading AMI. Thus, monitoring is needed to avoid risk of AHF.
