Apple Watch can detect weak heart pump with improved Mayo Clinic algorithm

The Mayo Clinic is working on an algorithm that can analyze electrocardiogram data recorded on the Apple Watch. The algorithm will be able to detect weaker heart pumps directly from these EKG tests. This could potentially detect life-threatening conditions at an early stage for users without having to be in a medical setting.

The algorithm was presented at the Heart Rhythm Society meeting in San Francisco. The algorithm accurately detected weak heart pumps in a small number of patients, the study found. The testing was part of a decentralized study that included 125,000 Apple Watch EKG tests from participants in the U.S. and 11 countries.

The clinic's cardiologists believe the new results will "establish the early feasibility of embedding this capability into [Apple Watch]."

This shows that you can design studies to explore the utility of single-lead (EKG) devices such as the Apple Watch for clinical questions, and the researchers need to be commended for this. This should be considered a first step, but in no way ready for prime time.

The study also drew on data from more than 2,400 people who had recently undergone an electrocardiogram. . A Mayo Clinic app uses the algorithm to analyze EKG traces. Of the 16 patients who were said to have a weak heart pump, 13 of them were correct.

It helps detect heart problems early

While the algorithm would be best used on patients who are at higher risk for heart disease, it's unclear who would actually benefit. However, the clinic is working to improve this. It is currently conducting a study that will include 1 million people around the world to test various heart function algorithms. Its goal is to detect heart disease in patients earlier so they can receive treatment before their condition worsens.

According to the STAT article, weak heart pump is treatable and affects about 3% of people worldwide. People with weaker heart pumps are at greater risk for arrhythmias and heart disease.

If you are a person with high blood pressure and diabetes and you are over 60 years old, you may have a weak heart pump and not know it. You may not go to the doctor that often, but the impact of a watch you buy in a store that can tell you there's an important sign that you need to be screened can be huge.

More studies are underway to ensure The algorithm can be used with different individuals. It also aims to help high-risk patients seek better health outcomes earlier.

With more and more people buying Apple Watch for health purposes, it seems like it’s time to bring more benefits. This Apple Watch algorithm will take some time to improve, but it's good to see the progress. While these devices have saved lives before, they may save even more lives in the future.
