Study on the predictive effect of fibrinogen on vascular calcification

Fibrinogen, lipoprotein, and high-density lipoprotein levels were associated with vascular calcification, but their predictive capacity for a vascular calcification was not reported.

The purpose of this study was to evaluate the predictive efficacy of fibrinogen, lipoprotein, and high-density lipoprotein by retrospective analysis of fibrinogen, lipoprotein, and high-density lipoprotein levels in patients with vascular calcification, to explore the effective predictive indexes of vascular calcification, to predict the occurrence and development of vascular calcification, and to provide a simple and effective method for the diagnosis and prevention of vascular calcification.Hypothesis: Fibrinogen is a good prediction of vascular calcification.

Univariate and multivariate analyses were used to assess the effects of fibrinogen, lipoprotein, and high-density lipoprotein on the CV, and the ROC curve of the predictive model was used to assess its predictive effectiveness. We collected the relevant indicators of 462 patients admitted to the Department of Vascular Surgery of the First Hospital of Hebei Medical University from August 2018 to July 2020, including 189 patients with vascular calcification (40.9%) and 273 patients without vascular calcification (59.1%); 75% of the collected data is used for modeling (modeling group) and 25% for verification (verification group).

Results from the multivariate analysis showed fibrinogen, lipoprotein, and high-density lipoprotein to be independent predictors of vascular calcification. Next, the three-factor models are developed respectively. The area below the ROC curve in the fibrinogen, lipoprotein, and high-density lipoprotein forecast model was 0.8018, 0.7348, and 0.7019, respectively.

Fibrinogen is more predictive than high-density lipoprotein and lipoprotein in patients with arteriosclerosis.
