Design outcomes

| Measure | Time frame |
|---|---|
| Main Objective: The main target of this prospective pilot-study is to investigate the effects of lipid therapy intensification via the recently approved and very potent monoclonal, human anti-PCSK9 antibody Alirocumab on fractional anisotropy, endothelial function, inflammation, lipoprotein particle subfractions, carotid arteries and post-prandial lipemia in clinical routine at the Medical University of Graz. Main hypothesis: - Fractional anisotropy may be increased in response to Alirocumab.;Secondary Objective: Secondary hypothesis: - Lipid therapy intensification with Alirocumab may improve flow-dependent, endothelium-mediated dilation (Flow-Mediated Dilatation, FMD). - Alirocumab may reduce intima media thickness of the common carotid artery. - Alirocumab may improve the post-prandial lipemia profile. - Alirocumab may induce a change of the lipoprotein subfraction distribution. More precisely, Alirocumab is expected to reduce the number of LDL particles and to increase the number of HDL particles, especially of small ones. - Alirocumab may reduce inflammation ;Primary end point(s): Primary Endpoint: • Change of mean carotid vessel wall fractional anisotropy (2-Dimensional Cardiovascular Magnet Resonance) by very potent lipid-therapy intensification with Alirocumab. ;Timepoint(s) of evaluation of this end point: At week 10 (plus / minus 2 weeks) | — |
Secondary
