Coronary artery disease (CAD) progression seems more tightly linked to changes in non-high-density lipoprotein cholesterol (non-HDL-C) than to those in low-density lipoprotein cholesterol (LDL-C).
Researchers analyzed data from 9 clinical trials involving patients with CAD undergoing serial intravascular ultrasonography (n=4957) to compare changes in percent atheroma volume (ΔPAV) with lower vs higher on-treatment non-HDL-C and triglyceride (TG) levels.
Funding sources for the study were not disclosed.
Lower on-treatment non-HDL-C and TG levels were associated with significant PAV regression compared with higher non-HDL-C and TG levels across all levels of LDL-C and C-reactive protein and irrespective of diabetic status (P<.001 across all comparisons).
ΔPAV were more strongly influenced by changes in non-HDL-C (β=0.62; P<.001) compared with changes in LDL-C (β=0.51; P<.001).
Kaplan-Meier sensitivity analyses demonstrated significantly greater major adverse cardiovascular event rates in those...
