Plaque regression and stabilization by proprotein convertase subtilisin/kexin type 9 inhibitors: a meta-analysis of intravascular imaging studies

Key Points

This research aims to evaluate the effects of PCSK9 inhibitors on coronary plaque characteristics through intravascular imaging.
Conducted a meta-analysis of intravascular imaging studies
Analyzed plaque area volume (PAV) and lipid content changes
Assessed changes in fibrous cap thickness
PCSK9 inhibitors are linked to significant reduction in plaque area volume (PAV)
A decrease in lipid content within coronary plaques was observed
An increase in fibrous cap thickness was noted, indicating stabilization of plaques

Abstract

This comprehensive intravascular imaging meta-analysis demonstrates that PCSK9 inhibitors are associated with both regression and stabilization of coronary plaques, as evidenced by reductions in PAV and lipid content and increases in fibrous cap thickness. These imaging-based structural changes may underlie the cardiovascular benefits observed in major outcome trials.
