Abstract
Background/Synopsis
According to the American Heart Association, the accumulation of plaque in the walls of arteries is identified as the primary cause of atherosclerotic cardiovascular disease (ASCVD). Currently, ASCVD-related conditions remain the leading cause of morbidity and mortality globally. Apolipoprotein B has been identified as a more precise cardiovascular risk marker than LDL-C, while hsCRP has shown potential as a cardiovascular disease indicator. This study aims to investigate the diagnostic performance and routine screening cut-off of hsCRP for early atherosclerosis vascular diseases (ASCVD) risk in adult patients, comparing it with Apo B.
Objective/Purpose
To compare the diagnostic performance of high-sensitivity C-reactive protein (hsCRP) with apolipoprotein B in assessing ASCVD risk.
Methods
A sample of 494 individuals from the NHANES 2015-2016 laboratory dataset, with a mean age greater than 17 years, was used for this study. ASCVD risk was measured by non-HDL-C, categorized into low and high risk based on the Mayo Clinic reference range. Predictors included Apo B, and hs-CRP. Binomial logistic regression and ROC curve analyses were conducted using the generalised linear models and pROC packages in RStudio IDE. Hypotheses were validated at p≤0.05, and diagnostic performance metrics such as ROC AUC, sensitivity, and specificity were measured on a scale of 0-1.
Results
The findings revealed that for every 1g/L increase in apo B concentration, the odds of high ASCVD risk were approximately 3.8 × 1011 times higher. Additionally, the model indicated that the odds of high ASCVD risk were 1.03 times higher for every 1mg/L increase in hsCRP concentration. However, this indicate that hsCRP level was not associated with odds of ASCVD risk. The ROC AUC for apo B and hsCRP were approximately 0.9739 and 0.6165, respectively, with cut-off values (sensitivity, specificity) of approximately 0.9g/L (0.927, 0.897) and 2.4 mg/L (0.596, 0.601), respectively. Thus, levels above these thresholds for both apo B and hsCRP are associated with high ASCVD risk.
Conclusions
The study demonstrates that apo B exhibits high discriminatory and diagnostic accuracy, making it a suitable ASCVD risk biomarker compared to hsCRP. While hsCRP shows moderate diagnostic accuracy, it is not sufficient as a standalone ASCVD risk diagnostic marker. Therefore, apo B could serve as a replacement for LDL-C, while hsCRP could possibly serve as an add-on test in ASCVD risk assessment.
期刊介绍:
Because the scope of clinical lipidology is broad, the topics addressed by the Journal are equally diverse. Typical articles explore lipidology as it is practiced in the treatment setting, recent developments in pharmacological research, reports of treatment and trials, case studies, the impact of lifestyle modification, and similar academic material of interest to the practitioner. While preference is given to material of immediate practical concern, the science that underpins lipidology is forwarded by expert contributors so that evidence-based approaches to reducing cardiovascular and coronary heart disease can be made immediately available to our readers. Sections of the Journal will address pioneering studies and the clinicians who conduct them, case studies, ethical standards and conduct, professional guidance such as ATP and NCEP, editorial commentary, letters from readers, National Lipid Association (NLA) news and upcoming event information, as well as abstracts from the NLA annual scientific sessions and the scientific forums held by its chapters, when appropriate.
