Exploration of the Parameters Influencing the Effort Limitation of Patients Suffering From Homozygous Sickle Cell Anemia (PHYSIO-EXDRE)

December 16, 2024 updated by: Assistance Publique - Hôpitaux de Paris

Evaluation of Effort Limitation Parameters of Patients With Homozygous Sickle Cell Disease

The cardiovascular complications of sickle cell disease are associated with major morbidity and mortality, as well as impaired quality of life. Stratifying the cardiovascular risk of these patients solely on resting parameters (blood pressure, cardiac ultrasound) is limited. The hypothesis that an exhaustive analysis of the physiological parameters of exercise is launched allows more relevant phenotyping and therefore much better stratification of the individual risk of these patients..

Recent studies have shown a paradigm shift in the use of physical activity. Hitherto inadvisable (acidosis, vaso-occlusive crises), if adapted, moderate and regular, it can lead to functional improvement and a reduction in crises. As a result, cardiovascular exercise rehabilitation is becoming increasingly popular in this population.

It's easy to see how effort assessment, particularly through cardiorespiratory exchanges, will become more common in this pathology, making its analysis accessible and interesting.
