Abstract Background Effects independent from cholesterol reduction on vascular function are considered to importantly contribute to the beneficial effects of statin therapy in cardiovascular disease. We aimed to evaluate the effect of high versus low dose atorvastatin on endothelial dysfunction in patients with coronary artery disease (CAD) in a setting of comparable cholesterol reduction. Methods and results Fifty-eight patients with CAD were randomly assigned to double-blind treatment for 8 weeks with atorvastatin 80mg per day (A80) or atorvastatin 10mg+ezetimibe 10mg per day (A10E10), respectively. Flow-mediated vasodilation (FMD) of the brachial artery, nitroglycerin-mediated endotheliu…
