About this study
Official title: THETIS: Non-interventional, Multicenter Clinical Study to Evaluate the Predictive Value of the Heart Failure Questionnaire (HF-Q) for the Occurrence of Μajor Αdverse Cardiovascular Events (MACE) According to New York Heart Association Functional Classification (NYHA) in Patients With Symptomatic Heart Failure
Cardiac Heart Failure Questionnaire HF-Q) to assess the severity of the symptoms of Heart Failure. In this study, modified and translated, the "four-point" questionnaire by Severo and his associates - Heart Failure Questionnaire HF-Q, is used. The HF-Q Heart Failure Questionnaire consists of four closed questions: the first with four possible answers and the other three questions with the possibility of three simple-choice answers.
Read the detailed description
An important new element in recent guidelines is the recommendation to prevent the onset of heart failure syndrome and / or delay its progression. The degree of patient functional limitation is determined using the New York Heart Association (NYHA) classification, which in combination with the left ventricular ejection fraction is the main criterion for all clinical studies in HF.
Specifically, NYHA's functional classification is used to describe the severity of symptoms and exercise tolerance and includes 4 classes (I-IV) :
Class I: Unbound in physical activity. Conventional physical activity does not cause fatigue, palpitations or shortness of breath.
Class II: Mild limitation to physical activity. No symptoms in the calm, but ordinary physical activity causes fatigue, palpitations or shortness of breath.
Class III: Serious restriction to physical activity. No symptoms in the calm, but even mild physical activity causes fatigue, palpitations or shortness of breath.
Class IV: Inability to perform any physical activity without discomfort. Symptoms and seclusion. Strengthening the discomfort in any physical activity.
The study evaluates the predictive capacity of the Cardiac Deficiency Questionnaire (HF-Q) for the occurrence of Adverse Cardiovascular Stroke (MACE) according to the New York Heart Association (NYHA) Functional Classification of Heart Failure in patients with symptomatic Heart Failure .
This type of approach may be useful in the reproducibility of the results and the validity of the NYHA classification system, since the severity of the heart failure symptoms is recorded on the basis of the patient's own perception.
The term MACE or "Major Unwanted Cardiovascular Syndromes" is undoubtedly the most common and complex endpoint in cardiology research. Historically, the term MACE appears to be used in the mid-1990s with its use being mainly limited to the intra-muscular complications associated with transcutaneous coronary interventions (PCIs). Despite the widespread use of the term in clinical trials, the definitions of MACE may differ, which makes it difficult to compare similar studies.
The so-called "classic 3-point MACE" is defined based on the following17:
- Cardiovascular Death
- Myocardial infarction
- Cerebral Episode (Ischemic or Haemorrhagic) In general, MACE terminology is a complex clinical event and includes endpoints that reflect both safety and efficacy.
- Conditions
- Heart Failure, Heart Failure NYHA Class III, Heart Failure NYHA Class II, Heart Failure NYHA Class IV
- Medical subject headings
- Heart Failure

Questions about this trial
What is this clinical trial studying?
An observational study of Heart Failure and Heart Failure NYHA Class III, run by Elpen Pharmaceutical Co. Inc..
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: withdrawn, as of the sponsor's last update on 30 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Heart Failure Questionnaire (HF-Q) (time frame: 6 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03947853, which also lists 15 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Jan 2020.
