In response to the article on which the above post is based, the Journal of Child and Adolescent Psychopharmacology received three letters to the editor that raise substantial objections to the conclusions and methodology of the article.

All of the letter authors conclude that the study does not provide any evidence for a rsik of heart disease from stimulants. The only children on stimulants who died did not die from heart disease. Five children with ADHD had a serious cardiac event but none of the children were on stimulants.

One letter writer critqued the definition of cardiac event. Becasue a parent is anxious about heart disease in their stimulant taking child and brings them to an ER for this reason does not meAn that the child hadheart disease. The article seemed to count such visits as crdiac events. This is closely related to another critique; referral bias. This refers to the concept that knowing your child is on a medication believed to be related to heart difficulties may lead hte parent to seek heart evaluations more frequently.
Also, the letter writers note several other large scale studies that have failed to find a relationship between stimulant use and heart disease. These studies and the article discussed in my blog should serve to reassure parents about the absence of cardiac risk associated with taking stimulants.
