Digital heart-health app and lifestyle program for adults with heart disease or high-risk diabetes

An Innovative Technology-based Approach to Translating Clinical Practice Guidelines of Nutrition Therapy in Primary Care: The Coronary Heart Effectiveness Assessment of the Portfolio Diet in Primary Care (CHEAP) Trial

NA · University of Toronto · NCT06919302

This program will test whether adding a digital heart-health app and lifestyle support to usual care helps adults on statins with established heart disease or high-risk type 2 diabetes lower their cardiovascular risk.

What this trial studies

This randomized interventional study compares a digital heart-health program plus standard primary care to standard care alone in adults taking statin therapy. Participants use a web- and mobile-based app that provides nutrition and lifestyle guidance alongside routine clinical follow-up. Eligible participants are adults on a stable statin dose with either established atherosclerotic cardiovascular disease or older adults with treated type 2 diabetes and additional risk factors. The study will track changes in cardiovascular risk factors and related health measures over the follow-up period.

Who should consider this trial

Good fit: Adults on a stable statin dose for at least three months who have either established atherosclerotic cardiovascular disease (age ≥45) or are age ≥50 with treated type 2 diabetes plus additional risk factors are ideal candidates.

Not a fit: People not on stable statin therapy, those without cardiovascular disease or high-risk diabetes, or those unable or unwilling to use a smartphone or web app are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, the digital program could help patients improve diet and risk factors and possibly reduce future heart problems while saving clinician time.

How similar studies have performed: Similar digital lifestyle and app-based programs have shown modest improvements in risk factors like weight and blood pressure, but large-scale evidence for reducing major cardiovascular events remains limited.
