Brief Summary

The aim of study is to examine the relationship between lipid subfractions, inflammation and structural-functional properties of the arterial wall in patients with premature coronary heart disease, to study genetic polymorphisms that determine lipid subfractions concentration on the functional and morphological properties of the arterial vascular wall in patients with early coronary heart disease, to study the effect of alirocumab and evolocumab on lipid subfractions, inflammation and structural-functional properties of arterial wall in patients with early coronary atherosclerosis and to study the influence of NOS-3 gene expression on the functional and morphological properties of the arterial vascular wall in the same patients. Impaired blood fat metabolism and chronic inflammation are intertwined as possible causes of atherosclerosis. Lipoprotein (a) (Lp (a)) is an important risk factor for coronary heart disease and a prognostic predictor in patients after myocardial infarction, but recent research suggests that subtilisin-kexin convertase type 9 (PCSK9) inhibitors are the only drugs that significantly reduce serum Lp (a) concentration. However, there are no data on the relationship between Lp (a) values and polymorphisms for Lp (a), indicators of inflammation and impaired arterial function, and response to treatment with various PCSK9 inhibitors in patients with early coronary heart disease.

Outcome Measures

Primary Outcomes (3)

  • Ultrasound functional and morphological properties of the arterial wall and Lp (a) concentration

    Functional and morphological characteristics of arterial wall will correlate to Lp (a) concentrations.

    Baseline

  • Concentration of Lp (a) and SNP in the LPA gene

    The serum concentration of Lp (a) will correlate with single nucleotide polymorphisms (SNP) in the LPA gene

    Baseline

  • The effect of alirocumab or evolocumab on functional and morphological properties of arterial wall after 6 months

    Both drugs will improve functional and morphological properties of arterial wall in with no difference between the drugs. We expect the improvements in each drug group will be in correlation with the decrease of Lp (a) concentration.

    6 months

Study Arms (3)

Alirocumab

EXPERIMENTAL

The first group of patients will receive 150 mg of alirocumab every two weeks subcutaneously for 6 months

Drug: Alirocumab

Evolocumab

EXPERIMENTAL

the second group of patients will receive evolocumab 140 mg every two weeks subcutaneously for 6 months

Drug: Evolocumab

Control group

EXPERIMENTAL

Control group will be included in the treatment after 6 months. During this time, the control group will not receive treatment with alirocumab or evolocumab, only standard guidelines-based treatment

Drug: Control group

Interventions

The first group will receive alirocumab. Blood samples from all patients will be drawn for laboratory measurements and genetics determination. Ultrasound measurement of endothelium-dependent dilatation of the brachial artery, intima media thickness of carotid arteries and pulse wave will be measured.

Alirocumab

The second group will receive evolocumab. Blood samples from all patients will be drawn for laboratory measurements and genetics determination. Ultrasound measurement of endothelium-dependent dilatation of the brachial artery, intima media thickness of carotid arteries and pulse wave will be measured.

Evolocumab

The third group will receive only optimal guidelines-based secondary preventive treatment. Blood samples from all patients will be drawn for laboratory measurements and genetics determination. Ultrasound measurement of endothelium-dependent dilatation of the brachial artery, intima media thickness of carotid arteries and pulse wave will be measured.

Control group
