Apple Watch can help you Spot an Another Fatal Cardiac illness, Results of Mayo Clinic

Apple Watch may be able to save your life in ever-new ways, according to medical researchers around the globe. The ECG capabilities of the Apple Watch are examined in greater detail in a recent study from Mayo Clinic researchers, with an emphasis on identifying heart anomalies such left ventricular failure.

This study, which was first reported by MyHealthyApple, is significant because left ventricular dysfunction frequently occurs after congestive heart failure:

Left Ventricular dysfunction of the heart is usually followed by congestive heart failure that can lead to a multitude of cardiac disorders.

The left ventricle is primarily responsible for pumping oxygen to your body’s vital organs. It is, therefore, important to diagnose any problems with the left ventricle as early as possible.

According to the Mayo Clinic study, cardiac dysfunction frequently goes undiagnosed because it has no symptoms, which means that those who have it are unaware of it. It would be a significant development if a device like the Apple Watch could detect it passively or assist in its diagnosis.

2,454 patients from the United States and 11 other nations participated in the study. Between August 2021 and February 2022, these participants sent over 125,000 ECGs from their Apple Watch. The researchers then “scrubbed and processed these results using a proprietary AI algorithm they developed.”

The AI algorithm detected patients with low EF(ejection fraction) with an area under the curve of 0.885 (95% confidence interval 0.823–0.946) and 0.881 (0.815–0.947), using the mean prediction within a 30-d window or the closest ECG relative to the echocardiogram that determined the EF, respectively.

The results demonstrate that “consumer-watch ECGs recorded in nonclinical contexts can detect patients with heart dysfunction,” according to MyHealthyApple. The study also implies that “smartwatches’ potential to support the execution of remote digital health studies is currently in its early stages.”

This past week, Nature Medicine published the complete study findings. The FDA is currently examining the Mayo Clinic’s proprietary AI algorithm.
