Data presented as median [interquartile range]. CAC indicates coronary artery calcium score; LDL‐C, low‐density lipoprotein cholesterol; and MET, metabolic equivalent of task.
Adjusted for age, sex, body mass index, diastolic blood pressure, diabetes mellitus status, level of LDL‐C and triglyceride, and medications, which include statin, angiotensin receptor blocker, thiazide diuretic, furosemide, and calcium‐channel blocker. Bonferroni adjusted P values are P=1.0 for fatty plaque; P=0.14 for fibrous plaque; P=0.32 for noncalcified plaque; P=0.19 for total plaque; and P=0.04 for CAC score.
Plaque volume expressed as mm3 divided by artery segment length (mm).
CAC score using Agatston technique and expressed in Agatston units.
