Study summary

The main objective will be to evaluate the changes in the cognitive function in naive patients treated with PCSK9 inhibitors (Alirocumab and Evolocumab) by using the Montreal Cognitive Assesment questionnaire (MOCA).

The secondary objectives will be: 1) To evaluate the levels of LDL-cholesterol changes from the beginning to the end of the study 2) To evaluate changes in Quality of Life among the EuroQol EQ-5D-3L questionnaire (it will also be associated to the cognitive function) 3) Assesment of direct costs in medications and outpatients consultations related with the health procedures.

What researchers measure

Primary outcomes

  1. Changes in cognitive function

    Assesment by Montreal Cognitive Assessment questionnaire (MOCA). Minimum value is 0 and maximum value is 30. A higher or equal value to 26 points will be considered normal.

    Time frame: 24 to 36 months

Secondary outcomes

  1. LDL-cholesterol values

    LDL-cholesterol changes will be assessed during the study by routine sample tests (mg/dL)

    Time frame: 24 to 36 months

  2. Changes in Quality of life

    By using the questionnaire called EuroQol EQ-5D-3L assessment. It has 2 parts, the first one has 5 questions with 3 possible answers (5 dimensions and 3 levels), so each health status has a rate called EVA from 1,0000 (the highest value) to - 0,5095 (the worst health status). The second part is a visual self-assessment between 0 (the worst health status) and 100 (the best health status). https://euroqol.org/

    Time frame: 24 to 36 months

  3. Direct costs

    Direct costs related with treatments and consultations (€)

    Time frame: 24 to 36 months

Other outcomes

  1. Total Cholesterol

    Total cholesterol evolution during the study in mg/dL

    Time frame: 24 to 36 months

  2. Lp(a)

    Lp(a) evolution during the study in mg/dL

    Time frame: 24 to 36 months

  3. Cost-effectiveness

    Time frame: 24 to 36 months
