Abstract 17270: Digital Health Intervention During Cardiac Rehabilitation Reduces Emergency Department Visits and Improves Weight Loss: A Randomized Controlled Trial
Background: Digital health interventions (DHI) improve intermediates of cardiovascular (CV) health, but data regarding their impact on outcomes are lacking. The current study was designed to address the hypothesis that DHI administered during cardiac rehabilitation (CR) would reduce emergency department (ED) visits and rehospitalizations in patients after acute coronary syndrome (ACS).
Methods: Eighty patients undergoing CR following ACS were prospectively randomized to either usual CR (n=40) or CR+DHI (n=40) for three months. DHI entailed educational and metric-tracking extensions of usual CR. Weight, blood pressure, lipids, diet, and activity were compared at 90 days, and ED visits plus rehospitalizations evaluated at 180 days.
Results: Baseline demographics were similar between the groups. The DHI+CR group had improved weight loss compared to the control group (-5.1±6.5 kg vs. -0.8±3.8 kg, respectively, p=0.02). Those in the DHI + CR group also showed a strong trend towards reduced CV-related rehospitalizations plus ED visits compared to the control group at 180 days (8.1% vs. 26.6%; RR 0.30, 95% CI 0.08 to 1.10, p=0.054).
Conclusion: This study demonstrates for the first time that DHI may reduce CV-related ED visits and rehospitalizations in patients 6 months after ACS. DHI may constitute a useful adjunct to CR to improve outcomes in the secondary prevention of cardiovascular disease.
Figure: DHI during CR reduces cardiovascular-related ED visits + rehospitalizations by 6 months after ACS.
