Stimulants and atomoxetine should generally not be used or used only with caution in adults with pre-existing cardiovascular conditions. The extent to which pre-existing cardiovascular conditions influence initiation of these ADHD medications in adults is not known.
We performed a retrospective cohort study of privately insured adults with new ADHD treatment episodes. Pre-existing cardiovascular conditions were assessed by the presence of ICD-9-CM codes for congenital abnormalities, atherosclerosis, cardiac disease, and cerebrovascular disease in the 12 months before the index ADHD diagnosis. The primary outcome was new initiation of a stimulant or atomoxetine in the 3 months after the index date. Multivariate logistic regression was used to predict the likelihood of treatment initiation with stimulants or atomoxetine based on pre-existing cardiovascular conditions, patient demographic characteristics, clinical mental disorder comorbidities, other psychotropic drug use, and provider type.
Of 8752 patients with a new ADHD treatment episode, 917 (10.5%) had evidence of >or=1 pre-existing cardiovascular condition. Stimulants were started by 40.8% of patients with and 53.0% of patients without pre-existing cardiovascular conditions (Adjusted Odds Ratio, AOR 0.71; 95%CI 0.61-0.82). Pre-existing cardiovascular conditions reduced the likelihood of initiating stimulant treatment in younger but not in older patients (p-value for age x cardiovascular condition interaction = 0.0002). Initiation of atomoxetine treatment was not affected by pre-existing cardiovascular conditions (AOR 1.19, 95%CI 0.94-1.50).
Pre-existing cardiovascular conditions reduce the likelihood of stimulant therapy but not atomoxetine treatment in adult ADHD patients. However, many adult ADHD patients with pre-existing cardiovascular conditions initiate stimulant therapy.

ABSTRACT: Recent studies suggest an association between attention-deficit/hyperactivity disorder (ADHD) and obesity. In this article, we systematically review and critically discuss evidence on the prevalence of ADHD in obese patients as well as the weight status of individuals with ADHD. Relevant articles were searched in PubMed, PsychInfo, and ISI Web of Science (January 1980 to June 2010). We found that current evidence indicates a high prevalence of ADHD in clinical samples of patients seeking treatment for their obesity. Moreover, available studies show that individuals with ADHD have higher-than-average body mass index z scores and/or a significantly higher prevalence of obesity compared with subjects without ADHD. Three mechanisms underlying the association between ADHD and obesity have been proposed: 1) it is possible that obesity and/or factors associated with it (such as sleep-disordered breathing) manifest as ADHD-like symptoms; 2) ADHD and obesity share common biological dysfunctions; and 3) ADHD contributes to obesity. With regards to the possible clinical implications, our findings suggest that it is noteworthy to screen for ADHD in patients with obesity and to look for abnormal eating behaviors as possible contributing factors of obesity in patients with ADHD. Based on preliminary findings, appropriate treatment of ADHD may improve the weight status of individuals with both obesity and ADHD.

ABSTRACT: Most major psychiatric disorders have an onset in childhood or adolescence in a sizeable proportion of patients, and earlier onset disorders often have a severe and chronic course that can seriously disrupt sensitive developmental periods, with lifelong adverse consequences. Accordingly, psychopharmacologic treatments have been increasingly utilized in severely ill youth. However, the increased use of psychopharmacologic treatments in pediatric patients has also raised concerns regarding a potential overdiagnosis and overtreatment of youth, without adequate data regarding the pediatric efficacy and safety of psychotropic agents. Over the past decade, a remarkable number of pediatric randomized controlled trials have been completed, especially with psychostimulants, antidepressants, and antipsychotics. For these frequently used agents, effect sizes against placebo have typically been at least moderate, with most numbers-needed-to-treat well below 10 for response, indicating clinical significance as well. Nevertheless, data also point to a greater and/or different profile of susceptibility to adverse effects in pediatric compared to adult patients, as well as to a role for nonpharmacologic treatments, given alone or combined with pharmacotherapy, for many of the youth. Taken together, these results highlight the need for a careful assessment of the risk-benefit relationship of psychopharmacologic treatments in patients who cannot be managed sufficiently with nonpharmacologic interventions and for routine, proactive adverse effect monitoring and management. Although considerable progress has been made, there is still enormous need for additional data and funding of pediatric psychopharmacology trials. It is hoped that the field will acquire the necessary resources to propel pediatric clinical psychopharmacology to new levels of insight by linking it with, but not replacing it by, pharmacoepidemiologic and biomarker approaches and advances.
