STUDY DESIGN An open-label, prospective phase III study to compare the efficacy and safety of administering evolocumab versus treatment with LDLapheresis in patients with familial hypercholesterolemia and high cardiovascular risk.~STUDY POPULATION The chosen population is constituted by patients belonging to the LDL-apheresis program of the General University Hospital Gregorio Marañón with the diagnosis of familial hypercholesterolemia and a history of cardiovascular disease.~Number of patients expected to participate in the study according to the base of patients treated with LDL-apheresis: 10.~STUDY DESIGN:~Non-controlled intervention study to evaluate the different therapies in the treatment of hypercholesterolemia, in which each patient will be self-controlled. The variables will be analyzed during different phases~LDL-apheresis phase: Retrospectively during the previous year, pre- and postapheresis variables will be collected from the following lipid parameters: total cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides, atherogenicity index, Lipoprotein A, apo-A, apo- B; inflammatory parameters: PCR, ferritin, fibrinogen, leukocytes and polymorphonuclear and immunological parameters: immunoglobulins and complement.~Evolocumab phase: LDL-apheresis will be suspended for three months and Evolocumab administered: 140 mg / 15 days subcutaneously. The same parameters indicated in the previous section will be measured every two weeks.~Combined phase: During the following three months evolocumab will continue to be administered biweekly and the LDL-apheresis procedure will be spaced from biweekly to monthly, the same analytical parameters being measured again every two weeks.
