Analysis of correlation between heart failure in the early stage of acute myocardial infarction and serum pregnancy associated plasma protein-A, prealbumin, C-reactive protein, and brain natriuretic peptide levels

Background: The study sought to analyze the predictive value of the early measurement of pregnancy associated plasma protein-A (PAPP-A), prealbumin (PAB), C-reactive protein (CRP), brain natriuretic peptide (BNP), and other indicators of heart failure (HF) after acute myocardial infarction (AMI). Methods: A total of 200 AMI patients admitted to Wuyi People's Hospital from November 1, 2019 to October 31, 2020 were continuously enrolled as the research objects and divided into a IIF group (Killip class II or above, n=94) and HF-free group (Killip dass I or below, n=106) according to the Killip Classification for Heart Function. Results: The age, creatine kinase-myocardial band (CK-MB), PAPP-A, CRP, suppression of tumorigenicity 2 (ST2), BNP, aldosterone (ALD), and left ventricular end-diastolic diameter (LVEDD) of the HF group were all significantly higher than those of the HF-free group, while the PAB and left ventricular ejection fraction (LVEF) were significantly lower (P<0.05). The PAPP-A, CRP, and BNP of HF patients increased as the Killip class increased, while the PAB decreased progressively (P<0.05). After including the statistically significant single factors in a multivariate logistic regression analysis, it was found that PAPP-A, PAB, CRP, and BNP were the independent influencing factors causing I IF in the early stage of AMI; and the diagnostic efficacy of HF in the early stage of AMI (from high to low) was combined test, PAPP-A, PAB, BNP and CRP. Conclusions: Serum PAPP-A, PAB, CRP and BNP levels are the independent influencing factors of HF after AMI, but comprehensive tests of clinical indicators, including PAPP-A, PAB, CRP, and BNP, are more accurate at predicting and evaluating HF and can be used to guide clinical decisions.

Automated summary

The study showed that PAPP-A, PAB, CRP, and BNP are independent influencing factors of HF after AMI, and comprehensive tests of these indicators are more accurate in predicting and evaluating HF.
