- Brief Summary
This is a prospective multicenter study to decipher phenotypic variability within patients with heart failure and preserved left ventricular ejection fraction (HFpEF). From a registry of heart failure patients (2500 anticipated) hospitalized in the participating centers in the last 3 years, up to 300 participants (with a final ratio of 3 HFpEF patients, 2 patients with heart failure and reduced ejection fraction (HFrEF) and 1 matched subjects without heart failure will be enrolled for an extensive phenotyping with physical evaluation, biomarkers and omics, cardiac and vascular imaging and telemonitoring of cardiovascular parameters. Cluster analysis with machine learning methods will be performed to define phenogroups unique to the HFpEF patient population.
- Detailed Description
Heart failure with preserved ejection fraction (HFpEF) is a complex and prevalent syndrome with currently no efficient therapy. This syndrome is likely explained by different pathophysiological inputs leading to common symptoms of heart failure. These pathophysiological abnormalities can primarily involve the heart but also other organs with secondary impact on the myocardium. There is however no clear understanding and diagnostic algorithms of the different HFpEF subpopulations. Novel mathematical methods (such as machine learning) can help identifying clusters within an heterogeneous population such as HFpEF patients.
A registry (2500 anticipated) will be constituted with patients hospitalized for congestive heart failure in the participating centers during the last 3 years. From this registry, up to 500 patients will be invited to visit in the hospital for 8-10 hours for physical examination, ECG, performance-based tests, blood draw, cMRI, echocardiography (rest and low-level exercise), Ultrafast echo (for non-invasive measurement of myocardial stiffness), low radiation cardiac CT (for calcium scoring), non-invasive measurement of arterial stiffness. They will be asked to fill out questionnaires about dyspnea, depression and about general health and quality of life. They will then be equipped with a smart connected garment (with cardiovascular \& hemodynamic sensors), a connected weight balance and a blood pressure monitoring device for telemonitoring collection of cardiovascular hemodynamic parameters in real-life conditions (for 14 days).
Patients included in the registry will be followed-up for 3 years using medico-administrative databases and vital status, cardiovascular and heart failure outcomes will be collected.
