    5. Study Description

    Brief Summary
    The MARKOV study is an investigator-sponsored single arm, prospective study to assess the effect of evolocumab on the improvement in coronary flow (FFRCT) after 18 and 36 months of treatment in patients with coronary atherosclerosis.
    Detailed Description
    The MARKOV study is an investigator-initiated, open-label, single arm, international, multicenter, prospective study to assess the effect of evolocumab on the improvement in coronary flow (FFRCT) after 18 and 36 months of treatment in patients with coronary atherosclerosis. The study will be conducted in 5 sites in 3 different countries in Europe. Patients will receive evolocumab for approximately 3 year. The expected duration of the entire study from First Subject First Visit to Last Subject Last Follow-up is 46 months (3 year and 10 months).
