Abstract:
Objective:To analyze the correlation of serum lipoprotein-associated phospholipase A2(Lp-PLA2)and nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3)levels with the severity of coronary heart disease in elderly patients.Methods:Clinical data of 200 elderly patients with coronary heart disease in the hospital from January 2017 to July 2019 were retrospectively collected.Data of 80 healthy elderly patients undergoing regular physical examinations in our hospital during the same period were collected and used as the healthy control group.All patients received laboratory tests using relevant parameters and coronary angiography on admission, with complete records of examination results for analysis.Based on SYNTAX scores from angiography of coronary artery lesions, all 200 elderly patients with coronary heart disease were further divided into a low-risk lesion subgroup, an intermediate-risk lesion subgroup and a high-risk lesion subgroup.The correlation of serum Lp-PLA2 and NLRP3 levels with the severity of coronary lesions was analyzed in elderly patients with coronary heart disease.Results:The mean SYNTAX score was 27.6±10.1.There were 60 cases with low-risk lesions, 68 cases with intermediate-risk lesions and 72 cases with high-risk lesions, accounting for 30.0%, 34.0% and 36.0%, respectively.The control group had the lowest serum levels of Lp-PLA2 and NLRP3, followed by the low-risk lesion, intermediate-risk lesion and high-risk lesion subgroups( F=305.026, 9.173 and 582.029, all P<0.001). Bivariate Pearson correlation analysis showed that serum levels of Lp-PLA2 and NLRP3 were positively correlated to the Syntax score in elderly patients with coronary heart disease( r=0.545 and 0.689, all P<0.001). Conclusions:Serum levels of Lp-PLA2 and NLRP3 are correlated to the severity of coronary artery disease in elderly patients with coronary heart disease.Overexpression of these two markers may indicate growing severity of coronary artery disease.Testing for serum Lp-PLA2 and NLRP3 levels in elderly patients with coronary heart disease can be considered to evaluate coronary lesions and treatment options in the future.
