“…Increased left ventricular (LV) mass and chamber sizes in the setting of normal systolic function are well-known findings in SCA (31)(32)(33)(34)(35) and have been attributed to a high-output state from the chronic anemia (31,36). More recently, evidence of diastolic dysfunction has emerged in patients with SCA (37)(38)(39)(40), the mechanism of which remains unknown. Unlike the iron overload-related diastolic dysfunction seen in patients with β-thalassemia (41), myocardial iron deposition is not seen in patients with SCA with diastolic dysfunction Significance Sickle cell anemia (SCA) is a common monogenic disorder associated with significant morbidity and mortality and a high incidence of unexplained sudden death in young adults.…”

“…Ces résultats concordent avec les données de la littérature [3, 1517]. Eddine et al[4] avaient montré que la dilatation de ventricule gauche ainsi que l'augmentation de la masse ventriculaire gauche était corrélée à l'anémie et non modifiée par le traitement par l'hydroxyurée.…”

“…La majorité des travaux de la littérature [3, 4] n'avaient pas retrouvé de dysfonction systolique en terme de fraction d’éjection du ventricule gauche ou de fraction de raccourcissement entre les patients drépanocytaires et non drépanocytaires. Certains auteurs [16, 21] ont rapporté une hyperkinésie, probablement en rapport avec l'anémie.…”
