Analyze the Results of Cardiorespiratory Stress Tests, Capillary Lactatemia Measurements at the Ear, Resting and Stress Echocardiography
Conditions
Brief summary
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.

Interventions
Simultaneous performance of an echocardiogram (part of the follow-up assessment for sickle cell heart disease) at rest and then during the cardiorespiratory stress test, and an ear capillary lactatemia analysis (already routinely performed to ensure the safety of the cardiorespiratory stress test) during the cardiorespiratory stress test routinely performed at Mondor University Hospital prior to cardiovascular rehabilitation programs.
