CArdio-Reno- Hepato -MEtabolic Disease iN Chronic Heart Failure (CARMEN-CHF)

Study aims to investigate the incidence, associations and prognostic value of CRGM and its components: chronic kidney disease, type 2 diabetes, atherosclerotic cardiovascular diseases, and non-alcoholic fatty liver disease in patients with different phenotypes and severity of clinical manifestations of CHF.

The CARMEN-CHF study is a multicenter, observational, prospective study of the KRGMB in patients with pre-onset CHF or clinically overt CHF. Patients who meet the study eligibility criteria and consent to participate must provide written informed consent prior to any study-related procedures. By signing the informed consent form, patients grant access to medical information for the purpose of verifying eligibility and collecting information during follow-up. To ensure a representative sample, it is planned to enroll at least 3,000 patients at study centers across Russia. The proportion of patients included based on pre-onset CHF will be limited to 25% of the entire cohort. The study's follow-up period is 24 months, during which four visits are planned: two telephone visits at 6 and 18 months, and two in-person visits at 12 and 24 months. If it is not possible to visit a doctor in person, it is permissible to collect information through telephone contacts with the patient or his relative or person caring for the patient.
