Abstract

Abstract:

Objective To explore the predictive value of ApoB/ApoA1 ratio on the degree of coronary artery lesions in patients with unstable angina (UA). Methods One hundred and seventy six patients with UA who were hospitalized and underwent coronary angiography in the Department of Cardiovascular Medicine, Hebei General Hospital from October 2019 to August 2021 were retrospectively analyzed. Clinical data of the enrolled patients were collected, ApoB/ApoA1 ratio was calculated, and Gensini score was calculated based on coronary angiography results. The median Gensini score of UA patients was used to divide the patients into the high Gensini score group (Gensini score ≥40) and low Gensini score group (Gensini score <40), and clinical data of patients in two groups were compared. Correlation analysis on Gensini scores and ApoB/ApoA1 ratio in UA patients was performed. Binary multivariate Logistic regression was applied to analyze the independent risk factors for high Gensini score. ROC curves were applied to analyze the diagnostic value of ApoB/ApoA1 ratio and other lipid indices for high Gensini score, and the best diagnostic threshold was determined by the Yordon index. Results The ApoB/ApoA1 ratio of patients in the high Gensini score group was significantly higher than that of patients in the low Gensini score group (P<0.01). The Gensini score of UA patients was positively correlated with the ApoB/ApoA1 ratio (r=0.321, P<0.01). Binary multivariate Logistic regression analysis showed that ApoB/ApoA1 ratio was an independent risk factor for severe coronary lesions (Gensini score ≥40) in UA patients (OR=4.593, 95%CI=2.434-8.664, P<0.01). ROC curve analysis showed that the diagnostic value of ApoB/ApoA1 ratio was higher than that of ApoB, TG, TC and LDL-C, with an AUC of 0.723(P<0.01), an optimal diagnostic threshold of 0.69, a sensitivity of 0.644 and a specificity of 0.742.Conclusion The ApoB/ApoA1 ratio is positively correlated with the degree of coronary artery lesion in UA patients, and it has a certain diagnostic and predictive value and serves an independent risk factor for severe coronary artery lesions in UA patients, delivering guiding significance in the clinical diagnosis and treatment of UA.
