About
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.
Full 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.
