Polypharmacy, Safety, and Medication Adherence in Patients With Chronic Heart Failure With Reduced and Mildly Reduced Ejection Fraction (FARAON)

June 12, 2026 updated by: National Medical Research Center for Therapy and Preventive Medicine

Prospective Observational Study of Polypharmacy, Safety, and Medication Adherence in Patients With HFrEF and HFmrEF: Data From the FARAON Registry

This prospective registry study (FARAON) aims to assess the prevalence, structure, safety profile, and dynamics of polypharmacy, as well as its association with medication adherence, quality of life, and clinical outcomes in multimorbid patients with HFrEF and HFmrEF, aiming to identify potentially inappropriate prescribing (over/mis/underprescribing) and determine factors linked to low adherence and adverse events.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

The proposed statistical analysis plan for validating the Modified Express Module focuses on comparing biomarker levels and echocardiographic data between patients with true and declarative adherence, using the two-step Spearman correlation analysis for construct validation. To secure intellectual property, the description emphasizes methodological steps-specifically, analyzing correlations before and after excluding high-lie-score patients-without disclosing the specific proprietary questionnaires used, masking them under functional terms.

Study Type

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

The study included patients with a confirmed diagnosis of chronic heart failure with reduced or mildly reduced ejection fraction (HFrEF/HFmrEF), verified by echocardiography within 3 months before enrollment. All participants provided written informed consent. Patients with documented mental disorders or severe cognitive impairment were excluded

Description

Inclusion Criteria:

  1. Patients with a confirmed diagnosis of chronic heart failure with reduced or mildly reduced ejection fraction (HFrEF / HFmrEF).
  2. Diagnosis of HFrEF or HFmrEF confirmed by echocardiography within 3 months prior to enrollment.
  3. Signed informed consent.

Exclusion Criteria:

  1. Documented mental disorders.
  2. Severe cognitive impairment

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Primary Outcome Measure
Time Frame: 12 months

Composite clinical endpoint (MACE and emergency medical care):

Incidence of all cause death, emergency hospitalization for heart failure decompensation, acute myocardial infarction, stroke, or emergency calls for underlying CHF
12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Medication adherence assessed by the National Society of Evidence-Based Pharmacotherapy Scale
Time Frame: Baseline, 3 months, 6 months, and 12 months
Medication adherence will be assessed using the National Society of Evidence-Based Pharmacotherapy Scale. Scores range from 0 to 4 points, with lower scores indicating better treatment adherence
Baseline, 3 months, 6 months, and 12 months
Quality of life assessed by the Kansas City Cardiomyopathy Questionnaire (KCCQ)
Time Frame: Baseline and 12 months
Quality of life will be assessed using the Kansas City Cardiomyopathy Questionnaire (KCCQ). Scores range from 0 to 100 points, with higher scores indicating better health status and quality of life.
Baseline and 12 months
Health literacy level assessed by a specialized screening tool
Time Frame: Baseline
Score ranges from 1 to 5 points. Higher scores indicate lower health literacy and greater need for medical reading assistance (1 is never needs help, 5 is always needs help)
Baseline
Response validity score assessed by the Modified Express Module
Time Frame: Baseline
Score ranges from 0 to 3 points. Higher scores indicate a greater tendency toward social desirability and declarative behavior (0-1 indicates true adherence/reliable reports, 2-3 indicates declarative adherence/high risk of overreporting compliance).

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 20, 2026

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
