Oral medication can be superior to IM injections for sedating children with congenital heart disease; however, the safety of all medications remains an issue.
Our study demonstrates that patients SCD on LTE have cardiac dysfunction based on elevated LVMPI. This may be a reflection of the global severity of disease. Our findings merit further investigation with serial monitoring of LVMPI on a larger number of patients with SCD.
The purpose of the study was to assess the feasibility and safety of symptom-limited cardiopulmonary stress testing (CPST) in children with sickle cell disease (SCD), who are on long-term erythrocytapheresis. Maximal symptom-limited CPST was performed in 16 children with SCD who were maintained on long-term erythrocytapheresis and the exercise response in this patient cohort was compared with those of a healthy control population. All patients completed the CPST without any complications. Twelve patients with SCD had significant reduction in aerobic capacity [peak oxygen consumption (VO2) <80% predicted]. No patient demonstrated evidence of myocardial ischemia. In summary, symptom-limited CPST can be performed safely in a subgroup of children with SCD and can yield valuable clinical information.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
