The NIH Pragmatic Trials Collaboratory Coordinating Center is pleased to announce that the Chat 4 Heart Health trial received approval to transition from the planning phase to the implementation phase of the study. Congratulations to Michael Ho and Sheana Bull, the Chat 4 Heart Health principal investigators, and their study team for reaching this important milestone!

Chat 4 Heart Health, an NIH Collaboratory Trial, will test the comparative effectiveness of 3 text messaging delivery strategies that have been shown to improve individuals’ self-management health behaviors, including physical activity and medication adherence. The study will provide evidence regarding the best population-based strategy for universal delivery to engage patients in self-management to improve the American Heart Association’s “Life’s Essential 8” measures for improving and maintaining cardiovascular health.

Bull and Ho spoke recently about the importance of the study at the NIH Pragmatic Trials Collaboratory’s 2024 Annual Steering Committee Meeting.

Bull is a professor of community and behavioral health and the director of the mHealth Impact Laboratory at the Colorado School of Public Health. Ho is a professor of medicine at the University of Colorado School of Medicine. They also led the Nudge study, another NIH Collaboratory Trial.

Chat 4 Heart Health is supported through a cooperative agreement from the National Heart, Lung, and Blood Institute. Learn more about Chat 4 Heart Health.
