Apple Watch app could save your life by detecting irregular heartbeat, study says - CNN

Has a new bar been set for wearable technologies? An Apple Watch may detect heart rate irregularities that subsequent medical tests confirm to be atrial fibrillation, according to preliminary findings from a new study. AFib is often undiagnosed since it might not cause noticeable symptoms, but it contributes to 130,000 deaths and 750,000 hospitalizations in the United States each year.

New results from the Apple-funded study, which have not been published or peer-reviewed, were presented Saturday at the American College of Cardiology Scientific Session in New Orleans.

"The study's findings have the potential to help patients and clinicians understand how devices like the Apple Watch can play a role in detecting conditions such as atrial fibrillation," Dr. Mintu Turakhia, co-principal investigator and associate professor of cardiovascular medicine at Stanford Medical School, said in a statement.

Turakhia and his colleagues conducted a virtual study with more than 400,000 participants to understand whether a mobile app using data from a heart rate pulse sensor can identify atrial fibrillation.

Participants had both an iPhone and an Apple Watch, though not the most recent version, which features built-in electrocardiography (ECG), because it was released after the study's launch.

Intermittently, a special app checked each participant's heart-rate pulse sensor for an irregular pulse, and if it was detected, the participant would receive a notification and was asked to schedule a telemedicine consultation with a study doctor. Next, the participant would be sent ambulatory (walking) ECG patches to record the rhythm of their heart for up to a week.

The findings suggest how wearables might help to detect conditions before they strike, the researchers say.

What I learned from donating a kidney to my 70-year-old father - Vox

Two summers ago, my father asked if I would give him one of my kidneys.

He was 70 at the time, suffering from kidney disease. I was 39 with a wife and two young kids, and I was blindsided by his request. I just said, "I'll think about it. Give me the information."

I did think about it. A year later, my father and I found ourselves at Saint Barnabas Medical Center in Livingston, New Jersey, where doctors would remove one of my kidneys and transplant it into him. It was one of the most difficult decisions I've ever made — and in the end, while it was certainly gratifying, what truly convinced me to do it was that all the facts and data told me that it was simply the sensible, practical, right thing to do.

You may have read Dylan Matthews's account on this very site of his kidney donation to a total stranger. It was a remarkably generous act, and I admire him deeply for it.

But that experience is fairly uncommon. The fact is that 95 percent of live donors give their kidneys to someone they know. Out of the more than 6,000 live donor transplants made last year in the United States, some 300 were donated to strangers. Most donors never thought this is something we would do until faced with the prospects of a loved one going into kidney failure.
