Background

The usefulness of the 2013 ACC-AHA guidelines for the management of blood cholesterol in the Asian population remains controversial. In this study, we investigated whether eligibility for statin therapy determined by the 2013 ACC-AHA guidelines is better aligned with the presence of subclinical coronary atherosclerosis detected by CCTA coronary computed tomography angiography compared to the previously recommended 2004 NCEP ATP III guidelines.

Methods

We collected the data from 5,837 asymptomatic subjects who underwent CCTA using MDCT during routine health examinations. Based on risk factor assessment and lipid data, we determined guideline-based eligibility for statin therapy according to the 2013 ACC-AHA and 2004 NCEP ATP III guidelines. We defined the presence and severity of subclinical coronary atherosclerosis detected in CCTA according to the presence of significant coronary artery stenosis defined as >50% stenosis, plaques, and the degree of coronary calcification.

Results

As compared to the 2004 ATP III guidelines, a significantly higher proportion of subjects with significant coronary stenosis 61.8% vs. 33.8%, plaques 52.3% vs. 24.7%, and higher CACS CACS >100, 63.6% vs. 26.5% was assigned to statin therapy using the 2013 ACC-AHA guidelines P < .001 for all variables. The area under the curves of the pooled cohort equation of the new guidelines in detecting significant stenosis, plaques, and higher CACS were significantly higher than those of the Framingham risk calculator.

Conclusions

Compared to the previous ATP III guidelines, the 2013 ACC-AHA guidelines were more sensitive in identifying subjects with subclinical coronary atherosclerosis detected by CCTA in an Asian population.
