Study design
The Atorvastatin vs. Simvastatin on Atherosclerosis Progression Study (ASAP-NL) is a two-arm clinical trial based at two clinical centres: at the University Medical Center Nijmegen and the Academic Medical Centre Amsterdam. The principal aim of the trial was to investigate the effect of Simvastatin (40mg/day) versus Atorvastatin (80mg/day) on atherosclerosis in patients with familial hypercholesterolaemia. Individuals were eligible for inclusion if they were aged between 30 and 70 years with familial hypercholesterolaemia and with a mean intima-media thickness of at least 0.7mm at the common carotid artery or at least 0.9mm at the carotid bulb. The ethics committees of the centres approved the protocol and written informed consent was obtained from participating individuals.
