Stroke Interventions in Clinical Trials
Printable Version
ACAPS
Asymptomatic Carotid Artery Plaque Study



Principal Investigator
Hartwell, Tyler, Study Chair

PI Address
Research Triangle Institute, Research Triangle Park, North Carolina



Study Size Actual:919
Max Age:79
Min Age:40
Status:
Trial complete. Results published 1995.

Purpose:
This study tested the effect of the HMG-CoA reductase inhibitor, lovastatin, on early-stage carotid atherosclerosis (as detected by B-mode ultrasonography) in 919 asymptomatic men and women, 40-79 years of age with moderately elevated LDL cholesterol.

Interventions:
Lovastatin
3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitor; lowers cholesterol
Warfarin
Anticoagulant (Vitamin K antagonist)

Year Started: 1988
Year Finished: 1998
Year Published: 1995


Design:
Double-blind, placebo-controlled, factorially designed study of 919 patients.

Inclusion Criteria
Men and women with early carotid atherosclerosis and LDL cholesterol between the 60th and 90th percentiles.

Patient Involvement:
Participants received lovastatin (20-40 mg/day) or lovastatin-placebo and warfarin (1 mg/day), or warfarin-placebo over a 3-year period.

Primary Outcome:
Progression of the mean maximum intimal-medial thickness (IMT) over 12 walls of both carotid arteries.

Results:
Lovastatin treatment was associated with a reduction in progression of mean maximum IMT (p < 0.001). Levels of LDL cholesterol were reduced by 28% (43.5 mg/dl [11.25 mmol/liter]) in the lovastatin group within 6 months (p < 0.0001) and remained stable throughout the follow-up period, whereas these levels remained essentially unchanged in the lovastatin-placebo group.
