“…The lost of elasticity when the red blood cells sickle, results in microvascular occlusions and myocardial cell damage. While the exact pathogenesis is multifactorial, the reduced blood flow and the resulting ischemia are a major factor in the damage to the myocardium [6,63]. Low hemoglobin levels in most SCD patients are associated with a high cardiac output secondary to an increase in the preload and decrease in the afterload, leading to cardiomegaly [6].…”

“…A right ventricular heart catheterization is the diagnostic measurement of choice for the most accurate diagnosis, but this invasive test is not a suitable screening tool [55]. Echocardiogram is widely used to screen for pulmonary hypertension [55,61,63].…”

“…Os graus de dilatação do ventrículo esquerdo e da hipertrofia estão associados com a gravidade da anemia e com a idade do paciente (HUTZ, 1981;LESTER et al, 1990;COVITZ et al, 1995;BATRA et al, 2002), sendo estas alterações cardíacas observadas em praticamente todos os pacientes (MARTINS et al, 1999), inclusive nas populações pediátricas (HERDY, AGUAS e CHEDID, 1983;ESTRADE et al, 1989;RIBERA, 2013).…”
