ABSTRACT
BACKGROUND:
Previously the stabilization of coronary plaque with atorvastatin was demonstrated in the TWINS (evaluaTion With simultaneous angIoscopy and iNtravascular ultraSound) study. The influence of the low-density lipoprotein cholesterol (LDL-C) level on plaque stabilization was analyzed. METHODS ANDRESULTS:
Patients (n=29) with hypercholesterolemia and coronary artery disease (CAD) were analyzed. They received atorvastatin (10-20mg/day) for 80 weeks and were divided into low (< 91 mg/dl) and high (≥ 91 mg/dl) LDL-C groups based on their 80-week LDL-C level. Angioscopy was performed before and after treatment. Yellow coronary plaques were classified into six grades (grades 0 to 5) and mean grade was determined for each patient. The LDL-C levels at week 28 and 80 were reduced in both low LDL-C groups (n=14, 140.3 to 77.9 and 75.9 mg/dl; P<0.001 both groups) and high LDL-C groups (n=15, 151.7 to 93.0 and 99.1mg/dl; P<0.001 both groups). Significant improvement in the mean grade was shown in the low LDL-C groups (1.44 to 1.00 and 1.05; P=0.003 both groups) at week 28 and 80 vs. no significant change in high LDL-C groups (1.43 to 1.23 and 1.28; P=0.032 and P=0.169 respectively).CONCLUSIONS:
Adequate reduction of LDL-C is important for the stabilization of coronary plaques.
