Wearable Watches May Boost Remote Heart Rehab Success

Heart disease still tops the list as the world's biggest killer. But many people who need heart rehab never finish it. That could be changing thanks to smartwatches and fitness trackers. A new study looked at how wrist-worn devices help people do cardiac rehab from home or in a mix of home and clinic visits.

The research pulled together data from eight major health databases. They searched for studies published between January 2015 and August 2026. Only randomized controlled trials counted. These were studies where adults with heart conditions used a wrist device as part of their rehab program.

They left out studies focused mainly on heart failure. Studies that used wearables just to track results were also skipped. The team wanted to see real programs where the device guided the rehab process.

The main things they measured were how much oxygen people could use during exercise, how far they could walk in six minutes, and how many steps they took each day. They also looked at quality of life scores.

Using special math tools, they combined results from all the studies. This helped them see if the wearable-guided rehab actually worked better than usual care. The DerSimonian-Laird method helped them handle differences between studies.

Early signs suggest these wrist devices may help people stick with their rehab. Remote and hybrid programs using wearables showed promise. But the benefits were not always the same across every study. More research is needed to confirm the results.

Still, the idea is simple: give people tools they already wear to help them get healthier. If smartwatches can keep more heart patients on track, that could save lives. The key is making sure the tech works for real people, not just in labs.
