Correlation analysis of serum endothelial cell specific molecule-1, endothelial microparticles, hypoxia inducible factor-1α levels and acute myocardial infarction and their predictive value for major adverse cardiovascular events: a retrospective study

TL;DR

This study found that high levels of ESM-1, EMPs, and HIF-1α in blood are linked to heart attacks and can predict future cardiovascular problems.

Contribution

The study identifies ESM-1, EMPs, and HIF-1α as potential biomarkers for predicting adverse cardiovascular events after heart attacks.

Findings

Serum levels of ESM-1, EMPs, and HIF-1α were significantly higher in AMI patients compared to healthy controls.

Elevated levels of these biomarkers were strongly associated with the development of MACE after AMI.

Combined evaluation of the three biomarkers showed high predictive accuracy for MACE with an AUC of 0.931.

Abstract

This study aimed to analyse the correlation of endothelial cell specific molecule-1 (ESM-1), endothelial microparticles (EMPs) and hypoxia inducible factor-1α (HIF-1α) serum levels with the occurrence of acute myocardial infarction (AMI) and determine their short-term predictive value for major adverse cardiovascular events (MACE) following AMI treatment.

Retrospective data analysis was performed on the medical records of 106 patients with AMI admitted to our hospital between October 2020 and October 2022. The control group consisted of 106 healthy volunteers that received a physical examination at our hospital’s physical examination centre within the same time frame. ESM-1, EMP and HIF-1α serum levels were compared between the two groups. Independent risk variables for AMI were examined. Furthermore, these individuals were separated into the poor prognosis group (n = 41) and good prognosis group (n = 65) according to the presence or absence of MACE. Finally, the ESM-1, EMPs and HIF-1α serum levels were correlated with the development of MACE in patients with AMI, and the predictive value of serum ESM-1, EMPs and HIF-1α for MACE was evaluated. The serum HIF-1α, EMP and ESM-1 levels were significantly different between the two groups (P < 0.05). Multivariate logistic regression analysis revealed the elevated serum levels of HIF-1α (odds ratio (OR) = 1.819), EMPs (OR = 1.071) and ESM-1 (OR = 14.655) as AMI risk variables. A substantially significant (P < 0.05) correlation was found between the elevated levels of serum HIF-1α (OR = 18.716), EMPs (OR = 26.185) and ESM-1 (OR = 13.992) and the development of MACE in patients with AMI. According to receiver operating characteristic (ROC) curve analysis, the combined evaluation value of HIF-1α, EMPs and ESM-1 serum levels in predicting MACE was high with an area under the curve (AUC) of 0.931.

Patients with AMI have abnormally high ESM-1, EMP and HIF-1α levels in their serum, all of which have been linked to the development of MACE. Together, these parameters have high sensitivity and specificity for early MACE identification.
