The goal of this study is to assess the discriminatory power of a previously developed tool for detecting decompensated heart failure-which includes, in particular, clinical signs-in a population of patients hospitalized in cardiology units in Réunion. The main question it aims to answer is : Would a simple and rapid screening tool for decompensated heart failure help identify a high probability of this condition in a population hospitalized in a cardiology unit in Réunion? This study includes patients aged 55 and older, who reside in Réunion, who were admitted on an unscheduled basis to the cardiology department at the Réunion University Hospital or the Ouest Réunion Hospital, for any reason (whether as an inpatient or in the intensive care unit)
The study is conducted in two phases:
Phase 1: Development of the new e-DELPHI consensus-based screening tool Phase 2: Administration of the Déspist'IC-Run early detection tool for decompensated heart failure and performance of the gold standard cardiology examination (RIPH3)
Aged 55 and older
Admitted on an unscheduled basis to the cardiology department at the CHU (North and South campuses) and the CHOR for any reason (in general wards or intensive care)
Residents of Réunion
Able to read and write French
Who cannot communicate in French
For whom it is impossible to administer the questionnaire
For whom the ETT and/or cardiology consultation are impossible
Who are under guardianship, conservatorship, or judicial protection
Patients aged 55 or older who reside on Réunion Island and are hospitalized in the cardiology department of the University Hospital (CHU) or the Centre Hospitalier Ouest Réunion (CHOR)

Estimating the discriminant validity of a tool for detecting decompensated heart failure
The probability of having decompensated heart failure, as determined by a screening tool in the form of a questionnaire, will be calculated using the equation of a logistic regression model that explains the observed status (dependent variable) as determined by the gold standard test. The gold standard test for establishing a definitive diagnosis of decompensated heart failure will combine three tests: a clinical examination by a cardiologist, a transthoracic Doppler echocardiogram (TTE), and an electrocardiogram.
Describe the operational phases involved in developing the screening tool.
The detailed description of the tool's development phase is a task that complements statistical modeling (of the tool's development) and is purely epidemiological in nature.
Describe the sociodemographic and clinical characteristics, as well as the lifestyle habits, of the study population.
The following characteristics are collected: age, sex, socioeconomic status, residential area (north, south, west, east); cardiovascular risk factors (hypertension, diabetes, dyslipidemia, known heart disease, history of myocardial infarction, end-stage renal disease requiring dialysis); lifestyle factors (Body Mass Index (kg/m²), physical activity \> 30 min at least 3 times/week, current smoking, alcohol consumption \> 3 drinks/day).
Compare the sociodemographic and medical characteristics of this population of patients hospitalized in cardiology with those of other populations of patients with heart failure seen in private practices-whether in cardiology or general practice
Socio-demographic data (age, sex, residential area) and clinical data (cardiovascular history) for the population with heart failure in Réunion, obtained from the SNDS, will be compared with those of the sample in this study
