Clinical Trials

A clinical trial is a research study that allows volunteers to receive treatment with a drug or device currently under research testing by a pharmaceutical or biotechnology company. These companies carefully select qualified physicians who serve as "investigators” to lead the study trials.

Arkansas Children's offers opportunities to the community to participate in many studies. Use the search fields below to review the current available studies.

Flow-Mediated Dilation in Children

We are conducting a research study to find out if children can hold still long enough for researchers to use an ultrasound to take pictures of a blood vessel in a child’s upper arm before and after their blood pressure is taken. We expect that the study visit will take up to two and half hours. We hope that this study will help us learn more about children’s heart health. This study will include one visit. Upon completion of the study visit, you will be paid for your time.
