Simvastatin improved arterial compliance in high-risk patients.

Reduced arterial compliance is associated with arteriosclerosis. In some arteries, this is due in part to abnormal vascular tone, which can be altered by low-density lipoprotein (LDL) cholesterol reduction and statin therapy. We tested the effectiveness of statin therapy in improving arterial compliance in patients with manifest coronary disease (CAD) and/or diabetes.
