Apple Watch can help detect left ventricular dysfunction in apples


Medical researchers around the world continue to discover new ways Apple Watch can help save your life. A new study from Mayo Clinic researchers provides a deeper look at the ECG features of the Apple Watch, with a focus on detecting heart abnormalities such as left ventricular dysfunction.

As I first mentioned before MyHealthyApplethis is an important study, given that left ventricular dysfunction often follows it Congestive heart failure:

Left ventricular dysfunction of the heart usually follows congestive heart failure which can lead to several cardiac disorders.

The left ventricle is primarily responsible for pumping oxygen to the body’s vital organs. Therefore, it is important to diagnose any left ventricular problems as early as possible.

The Mayo Clinic study explains that heart failure often goes undiagnosed because it is asymptomatic, which means that people who have it do not know they have it. If something like the Apple Watch could passively detect it or help diagnose it, that would be a huge breakthrough.

The study included 2,454 patients from the United States and 11 other countries. These participants submitted more than 125,000 EKGs from their Apple Watch between August 2021 and February 2022. These results were then “scanned and processed via a proprietary AI algorithm developed by the researchers.”

The AI ​​algorithm detected patients with low EF (ejection fraction) with an area under the curve of 0.885 (95% CI 0.823-0.946) and 0.881 (0.815-0.947), using the mean prediction within a 30-day window or the closest ECG relative to a chart Echocardiograms determined by EF, respectively.

The results, as explained by them MyHealthApple, It has been shown that “consumer-monitored ECGs obtained in non-clinical settings can identify patients with abnormal heart function.” The study also notes that “the potential of smartwatches to assist in conducting digital health studies remotely is still in its infancy.”

The study results and full findings are published in Nature Medicine this week. The proprietary AI algorithm used by Mayo Clinic is currently being reviewed by the Food and Drug Administration.
