About this trial

True prevalence of FH in the Russian Federation is unknown which leads to low percentage of diagnosed and treated cases. Research is needed to determine the prevalence of FH, specific diagnostic algorithms and optimal treatment strategies. The main aim of the present study is to evaluate the extent to which FH is underdiagnosed and undertreated in the Russian Federation for reduction of cardiovascular risk related to atherosclerosis in the country.

As a first step, total cholesterol (TC) and low-density lipoprotein (LDL-C) levels will be determined in a random sample from Moscow population (n=18000). It is expected that TC ≥ 7.5 mmol/L will be detected in 10% of cohort. During 2014, approximately 500 patients will pass through non-invasive clinical examination at the Russian Cardiology Research and Production Center, including patient demographics, past medical history, family history of hypercholesterolemia, physical findings, current lipid-lowering therapies, blood tests, genetic analysis, echocardiography, carotid duplex ultrasound and exercise SPECT imaging in selected cases. On the basis of the Moscow Program four major Federal Medical Centers will be involved, and FH Registry will be created as a national, multi-center initiative to screen FH patients, control their diagnosis and management, and track clinical-reported outcomes over time.

Establishment of National Guidelines for the diagnosis and treatment of FH on the basis of these data and implementation those into clinical practice in different regions of Russia will allow improving patient care. As an expected outcome, this program will raise awareness and increase appropriate assessment and treatment of FH patients in Russia, leading to a timely detection of the disease and therapy initiation.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Total cholesterol ≥7.5 mmol/L or LDL-C ≥4.9 mmol/L (pretreatment levels)

Familial hypercholesterolemia defined as: a. Mutation in the LDL receptor and/or the ApoB gene and/or the PCSK9 gene; or b. clinical diagnosis of heterozygous FH (HeFH) according to the Dutch Lipid Network Criteria or Simon Broom Criteria

Patients with genetic mutation of FH

Disqualifiers

uncontrolled primary hypothyroidism (thyroid stimulating hormone (TSH) >1.5 x upper limit of normal (ULN)),

nephrotic syndrome and/or renal dysfunction (scrum creatinine >2.0 mg/dL or 160mmol/l, creatinine clearance <15 ml/min) at screening.

uncontrolled diabetes mellitus (Glycated hemoglobin >8.5%)

Trial population

Russian cohort of individuals who have been tested in the offices of the "INVITRO" Laboratory on the basis of advertising campaign for the purpose of total cholesterol level measurement and determination of cardiovascular risk with the use of SCORE chart.

Trial outcomes

Primary outcomes

1

Prevalence of FH patients in the Russian Federation

Time frame
at baseline

Secondary outcomes

1

Number of patients with heterozygous and homozygous forms of FH in Russia

Time frame
at baseline
2

Distribution of lipoprotein(a) in individuals diagnosed with definite and probable FH.

Time frame
at baseline
3

Severity of carotid atherosclerosis, aortic valve stenosis and coronary heart disease in Russian patients with FH

Assessment of carotid atherosclerosis will be performed with the use of carotid duplex scanning. Presence and severity of aortic valve stenosis will be evaluated with echocardiography. Exercise radionuclide myocardial perfusion imaging with single-photon emission computed tomography (SPECT) will be used for the diagnosis of myocardial ischemia in patients suspicious for CHD.

Time frame
at baseline
4

Mutations in following genes: low-density lipoprotein receptor (LDLR), proprotein convertase subtilisin/kexin type 9 (PCSK9), apolipoprotein B (apoB)

Genetic testing for FH-causing mutation in patients with probable and definite FH

Time frame
At baseline

Other outcomes

1

Clinical and diagnostic significance of Dutch Lipid Clinic Network criteria and Simon Broome Registry criteria for diagnosis of FH in Russian population

Clinical and diagnostic significance of Dutch Lipid Clinic Network criteria and Simon Broome Registry criteria for the diagnosis of FH in Russia.

Time frame
up to 5 years
2

Family Health Team model and cascade testing in individuals with FH

Time frame
up to 3 years
