Cardiovascular Risk of Stimulant Treatment in Pediatric Attention-Deficit/Hyperactivity Disorder: Update and Clinical Recommendations

ObjectiveThis review provides an update on the cardiovascular impact of therapeutic stimulant-class medication for children and adolescents with attention-deficit/hyperactivity disorder (ADHD).MethodRelevant clinical literature was ascertained using PubMed searches limited to human studies and the English language as of May 2011. Current practice guidelines and consensus statements also were reviewed.ResultsStimulant-class medications for healthy children and adolescents with ADHD are associated with mean elevations in blood pressure (≤5 mmHg) and heart rate (≤10 beats/min) without changes in electrocardiographic parameters. A subset (5–15%) of children and adolescents treated may have a greater increase in heart rate or blood pressure at a given assessment or may report a cardiovascular-type complaint during stimulant treatment. It is extremely rare for a child or adolescent receiving stimulant medication to have a serious cardiovascular event during treatment, with the risk appearing similar to groups of children not receiving stimulant medication.ConclusionsClinicians should adhere to current recommendations regarding the prescription of stimulant medications for youth with ADHD. Scientific inquiry is indicated to identify patients at heightened risk and to continue surveillance for the longer-term cardiovascular impact of these agents.
