Fasting serum concentration of apolipoprotein B48 represents residual risks in patients with new-onset and chronic coronary artery disease

► We evaluated fasting serum level of apoB48 as a marker for coronary artery disease (CAD). ► ApoB48 was an independent predictor of new-onset or chronic CAD, irrespective of LDL-C levels. ► ApoB48 was increased in patients with new lesion progression after coronary intervention. ► Fasting serum apoB48 concentration was a marker of CAD and predicts lesion progression.
