Seth Martin discusses how investigators used the Apple Watch to track heart rates of heart attack patients and found that heart rates tended to spike right before readmissions in some people.
Ah, project that we're presenting a H A Scientific sessions. This is led by Daniel Wang, who's one of our star medical students on the Corrie team. And so Daniel really dove into the heart rate. Data coming from the Apple Watch is part of the Cory platform. So in heart attack patients, we know that higher heart rates are associated with worse clinical outcomes. And so the Apple Watch provided an opportunity to see, uh, in more detail the heart rate trends in our patients as they recovered from a heart attack. And in general, if the heart rate is progressively improving, that would be a positive signal of thanks, cardiac recovery. And so, in our my core study, we collected over 4000 heart rate values from the Apple Watch as our patients recovered. And what Daniel showed is that there was a progressive improvement down towards heart rate levels after 30 days of around 70 with many patients getting below 70. And that would be an indicator that patients are getting better. Um, but in some cases of the patients who are re admitted, the what we also saw where there were heart rate signals that would go up above 90 beats per minute, proceeding those rehospitalization. So we also see that the heart rate stream could be used as an early risk indicator. And then in the future, potentially, we could pair that with interventions that could help patients address those problems sooner rather than later and hopefully avoid some of those hospitalizations.
