Diagnostic values of serum BNP, PTX3, and VEGF in acute pulmonary embolism complicated by pulmonary artery hypertension and their correlations with severity of pulmonary artery hypertension

Abstract

ObjectiveThis paper aimed to unveil the diagnostic values of serum brain natriuretic peptide (BNP), pentraxin 3 (PTX3), and vascular endothelial growth factor (VEGF) in acute pulmonary embolism complicated by pulmonary artery hypertension (APE‐PAH) and their correlations with severity of PAH.MethodsA total of 153 patients with APE were selected for our study and divided into the PAH and Non‐PAH groups according to the measurement of pulmonary artery pressure by echocardiography. Serum BNP levels were measured by chemiluminescence immunoassay, and serum PTX3 and VEGF levels were appraised by ELISA. The predictive values of BNP, PTX3, and VEGF for APE‐PAH were evaluated by applying the receiver operating characteristic (ROC) curve. Spearman test was implemented to correlate BNP, PTX3, and VEGF with the severity of PAH.ResultsHigher serum levels of BNP, PTX3, and VEGF were observed in the PAH group versus the Non‐PAH group (p < .05). ROC curve analysis indicated that BNP, PTX3, and VEGF had acceptable diagnostic value for predicting APE‐PAH. Higher serum levels of BNP, PTX3, and VEGF were witnessed in the moderate and severe PAH groups in contrast to the mild PAH group (p < .05), and the levels of these parameters were elevated in the severe PAH group versus the moderate PAH group (p < .05). Spearman correlation analysis signified that serum BNP (r = 0.377), PTX3 (r = 0.488), and VEGF (r = 0.575) levels were positively correlated with the severity of PAH in APE‐PAH patients.ConclusionSerum BNP, PTX3, and VEGF levels are significantly elevated in APE‐PAH patients. Serum BNP, PTX3, and VEGF levels are of clinical value in the diagnosis of APE‐PAH patients, and serum BNP, PTX3, and VEGF levels are positively correlated with the severity of PAH and can be used as predictors of the severity of PAH.

Application Value of Serum Cardiac Troponin T, Brain Natriuretic Peptide Levels and Electrocardiogram Changes in the Treatment and Prognosis Evaluation of Severe Pneumonia in Children

“…Singh et al 21 discovered that in patients undergoing non-cardiac surgery with hypertension and diabetes, preoperative and postoperative serum BNP levels are significantly elevated, making BNP an important predictor for perioperative and postoperative complications, hospital stay, and mortality rates in these patients. Zheng et al 22 found that BNP is significantly overexpressed in the serum of patients with acute pulmonary embolism combined with pulmonary hypertension, and its expression increases with the severity of pulmonary hypertension, having high diagnostic value for the disease, and correlates positively with disease severity, serving as a predictive marker for the severity of the condition. Our study found that the serum levels of BNP in the severe group before and after treatment were significantly higher than those in the mild group; the expression levels in the serum after treatment were significantly lower than before treatment; and the expression levels in the serum of the death group after treatment were significantly higher than those in the survival group, suggesting that BNP reflects cardiac functional changes due to stress in patients and is one of the reasons for worsening conditions, poor therapeutic effect, and poor prognosis in pneumonia patients.…”
