Abstract

Objectives Due to concerns about the safety of stimulants for ADHD, novel assessments of the cardiopulmonary impact of these agents are needed. Methods An open design of lisdexamfetamine (LDX) in 15 adults with DSM-IV ADHD. Following a psychiatric evaluation and medical history, subjects underwent echocardiography (TTE) and cardiopulmonary exercise testing (CPET). LDX was titrated to 70 mg daily over 6 weeks, followed by monthly visits to 6 months. Change in TTE and CPET measures were examined following up to 6 months of LDX. Results At endpoint, there were no significant alterations in indices of cardiac systolic performance, or in metabolic and ventilatory variables at maximum exertion (P values >0.05). We found significant mean changes in resting LV systolic dimension and Doppler diastolic indices. Change in heart rate recovery at 1 min met statistical significance (P = 0.05). Conclusions We did not detect clinically meaningful changes in cardiac structure and function or in metabolic and ventilatory variables at maximum exertion in ADHD adults receiving open LDX. The clinical significance of changes in resting LV dimension and indices of diastolic function are not in the direction of cardiomyopathy. Future large sample controlled study can examine these findings, as well as stimulants' impact on heart rate recovery.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • A 6-month study of LDX titrated to 70 mg/d in 15 patients (aged 18-60) using comprehensive provocative physiological testing including resting transthoracic echocardiogram and noninvasive cardiopulmonary exercise testing did not find clinically meaningful changes in cardiac structure or function at rest or during peak exertion.

    “A 6-month study where LDX was titrated to 70 mg/d in 15 patients (aged 18-60 years) used comprehensive, provocative physiological testing including resting transthoracic echocardiogram and noninvasive cardiopulmonary exercise testing and did not find clinically meaningful changes in cardiac structure or function at rest or during peak exertion.”
  • Postmarketing safety data are consistent with earlier reported adverse events, and poison centers have reported patients presenting with insomnia, dystonia, hallucinations, jitters, tachycardia, and chest pain.

    “Postmarketing safety data are consistent with the earlier reported adverse events, and poison centers have reported patients presenting with insomnia, dystonia, hallucinations, jitters, tachycardia, and chest pain.47”
  • At maximum exertion, diastolic blood pressure was significantly increased in hypertensive patients (P < .003), but not in healthy subjects.

    “At maximum exertion, diastolic blood pressure was significantly increased in hypertensive patients (P < .003), but not in healthy subjects, which may require further studies to elucidate the cause.”
  • In that study, no significant mean changes in metabolic and ventricular variables were noted.

    “Likewise, no significant mean changes in metabolic and ventricular variables were noted.48”
  • In that study, a decrease in left ventricular dimensions was observed; however, a more sensitive measure of LV size, a change in LV volume, was not noted.

    “A decrease in left ventricular (LV) dimensions was observed; however, a more sensitive measure of LV size, a change in LV volume, was not noted.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
