| Popis: | Objective Coronary artery calcification (CAC) is closely associated with adverse coronary artery events and mortality. Measuring the extent of CAC can lead to the early diagnosis of coronary artery atherosclerosis. In this study, we determined the association between the low-density lipoprotein cholesterol (LDL-C) and apolipoprotein B (ApoB) ratio, ApoB, and CAC and compared the usefulness of the LDL-C/ApoB ratio and ApoB for diagnosing CAC. Methods A total of 10 357 subjects who underwent self-paid health checkups from July 2006 to May 2016 were enrolled in this cross-sectional study. The extension of CAC was assessed using a coronary artery calcium score with electron-beam computed tomography. Subjects who had an Agatston calcium score >0 were defined as having CAC, whereas those with a score ≥400 were defined as having severe CAC. Low LDL-C/ApoB ratios were used to represent the predominance of small, dense LDL-C. Results The prevalence of subjects with coronary calcification increased with the quartile values of ApoB levels and low quartile values of LDL-C/ApoB ratios. The odds ratios for CAC and severe CAC were 2.9 [95% confidence interval (CI), 2.2-3.9] and 4.4 (95% CI, 3.3-5.9) among the highest quartile of ApoB compared with the lowest quartile, and 9.5 (95% CI, 8.3-10.9) and 103.0 (95% CI, 56.9-187.8) among the lowest quartile of LDL-C/ApoB ratios compared with the highest quartile. The areas under the curve of ApoB and LDL-C/ApoB ratio for the diagnosis of CAC and severe CAC were 0.591 versus 0.679 and 0.618 versus 0.787, respectively. The LCL-C/ApoB ratio was superior to ApoB in terms of diagnosing subjects with CAC and severe CAC. Conclusion The LDL-C/ApoB ratio is a superior indicator to ApoB in the diagnosis of subjects with CAC, it can be conveniently used to improve the diagnostic ability of ApoB for CAC. |
