In Japan, heart disease and cerebral ischemic disease are major causes of death. A decrease in the level of low-density lipoprotein cholesterol (LDL-C) through intensive treatment with statins positively correlates with a reduction in the volume of plaques in patients with cardiovascular disease. The METEOR trial, evaluating the effect of rosuvastatin on carotid intima-media thickness (IMT), was conducted only in Europe and the US. Here we planned another trial, the Justification for Atherosclerosis Regression Treatment (JART) study, to clarify the efficacy of intensive lipid-lowering therapy with rosuvastatin in Japanese with atherosclerosis.


Four hundred patients with hypercholesterolemia (LDL-C >or=140 mg/dL) and a maximum IMT of >or=1.1 mm will be treated for 24 months either with intensive lipid-lowering therapy with rosuvastatin (target LDL-C levels: 80 mg/dL for primary prevention, and 70 mg/dL for secondary prevention) or conventional lipid-lowering therapy with pravastatin (target LDL-C level: complying with JASGL2007). The primary endpoint will be the percent change of mean-IMT and the objectives of the study are to compare the two protocols.


The JART trial is a prospective, randomized, open-label, blinded end-point evaluation, multi-center, parallel-group, comparative study to examine the regressive effect of intensive lipid-lowering therapy with statins on atherosclerosis by evaluating IMT in the Japanese population.
