LncRNA-MYL2-2 and miR-124-3p Are Associated with Perioperative Neurocognitive Disorders in Patients after Cardiac Surgery

Abstract

Background

Perioperative neurocognitive disorders (PND) resulting from cardiac surgery is a complication with high morbidity and mortality. However, the pathogenesis is unknown.

Methods

For the sake of investigating the risk factors and mechanism of PND, we collected the characteristics and neurological scores of patients undergoing cardiac surgery in the Affiliated Traditional Chinese Medicine Hospital of Southwest Medical University and Affiliated Hospital of Southwest Medical University from Jan 1, 2016 to Dec 11, 2018.

Results

We found that age and left atrial thrombus are independent risk factors for PND after cardiac surgery. Furthermore, the serum of 29 patients was collected on the 7th day after cardiac surgery for detecting the expression of lncRNA-MYL2-2 and miR-124-3p. Increased lncRNA-MYL2-2 and decreased miR-124-3p in serum were associated with the decline of patients’ cognition.

Conclusions

LncRNA-MYL2-2 and miRNA-124-3p may jointly participate in the occurrence and development of PND after cardiac surgery. These important findings are advantaged to further understand the pathogenesis of PND and prevent it, provide new biomarkers for the diagnosis and monitoring of PND.
