Key result
An app-based lifestyle modification program did not significantly increase the proportion of post-PCI patients achieving ≥10% improvement in peak VO2 compared to usual care (41% vs. 39%, p=0.786).
Why the study?
Long-term outcomes after PCI remain suboptimal largely due to non-target lesion progression, and digital health lifestyle interventions may provide an alternative to standard care.

App-based program failed to improve peak VO2 post-PCI; leaves open whether refined digital tools can enhance risk factor control.

Yamada et al. (2026) conducted an RCT in post-PCI (n=152). App-based lifestyle modification program using IoT devices vs. Usual care was evaluated on Proportion achieving ≥ 10% improvement in peak oxygen uptake (VO2) (p=0.786). An app-based lifestyle modification program did not significantly increase the proportion of post-PCI patients achieving ≥10% improvement in peak VO2 compared to usual care (41% vs. 39%, p=0.786).
