Apple Watch Study Reports Success Identifying Heart Problem

Published

on

A new study suggests the Apple Watch was able to identify abnormal heart rates that could be linked to a serious heart condition.

More than 400,000 Apple Watch users volunteered for the study. It was a project of researchers at the Stanford University School of Medicine.

Apple, the American technology company, provided money for the study. Results were recently presented at a major conference on heart health in New Orleans, Louisiana.

The researchers looked for signs of atrial fibrillation, the most common form of irregular heartbeat. The condition, also called “a-fib,” results from the abnormal firing of electrical signals in the upper chambers of the heart.

Some people with atrial fibrillation feel changes in their heartbeat, while others do not. Because of this, many people do not know they have the condition.

People with untreated a-fib are about five times more likely to suffer a stroke. In the United States, a-fib causes an estimated 130,000 deaths and 750,000 hospitalizations each year.

People taking part in the study wore the Apple Watch for extended periods during 2017 and 2018. The devices contain an app that continuously gathers information without users having to do anything. It uses the watch’s light sensor technology to measure blood flow. The system is designed to identify changes that might show an irregular heartbeat.

The researchers said that out of those taking part, about 2,000 subjects received a warning from the device that they might have a problem.

Those individuals were then asked to contact a doctor, who decided whether they should receive a patch to more closely watch for a possible irregular heartbeat. The patch uses electrocardiography, or ECG technology. Electrocardiography is the process of measuring and recording electrical signals in the heart.

The study found that about 84 percent of the time, those who received warnings of irregular heartbeat activity were found to be experiencing a-fib at the time. Of those who received warnings and followed up by using an ECG patch, one third were found later to have a-fib.

Overall, about 57 percent of those taking part in the study sought some kind of medical attention, researchers said.

Lloyd Minor is head of Stanford’s School of Medicine. In a statement, he said the results show great promise in using technology to create “more predictive and preventive health care.”

Doctor Minor added that a-fib is just one example of a condition devices can help identify in the future. “This study opens the door to further research into wearable technologies and how they might be used to prevent disease before it strikes,” he said.

But some health researchers warned against making any general judgements based on the Apple-financed study. They have called for much more research to measure the effectiveness of wearable devices to identify signs of disease.

Richard Kovacs is with the American College of Cardiology. He was not involved with the study. Doctor Kovacs told the Associated Press that despite the results, the Apple Watch system “is not perfect.” He noted that since the study did not have a comparison group getting regular ECG measurements, there is no way of knowing if the device missed heartbeat problems. This could give users a false sense of security, he said.

Other experts agreed that more studies are needed before similar device-based health observation systems are widely recommended.

“I would not advise this to the overall general population,” said Valentin Fuster, director of New York’s Mount Sinai Heart system and a former American Heart Association president. He said he would rather see such systems tested in people with additional health risks, such as older adults with high blood pressure.

XIAOMI MI 9 REVIEW: CHEAP SPEED

Published

Lightning-fast performance at a low price… if you live in the right place

Xiaomi’s flagship Mi series of smartphones is usually relatively unremarkable. Unlike the notch-busting Mi Mix line, the Mi phones don’t tend to have particularly interesting designs, and Xiaomi doesn’t push the prices as far down as it can with the Redmi range. The Mi phones are always just pretty good, pretty affordable phones.

The Mi 9 is a little different. It doesn’t depart from the basic Mi formula of offering high-end specs in a mainstream design at a reasonable price. But more so than any other Mi series phone in the past, the ~$500 Mi 9 narrows the gap with its high-end flagship competitors even further. If you live in a country where the Mi 9 is available, there’s very little reason not to give it serious consideration.8VERGE SCORE

XIAOMI MI 9

GOOD STUFF

  • Excellent performance
  • Fast wireless charging
  • Incomparable value

BAD STUFF

  • No waterproofing
  • MIUI isn’t for everyone
  • Bad speaker

The Mi series has established its own design language at this point, and this continues with the Mi 9. There’s the same stainless steel frame that’s thinner on the sides than the top and bottom edges, leaving a curved glass panel to fill in the space. The left side of the phone has a dedicated Google Assistant button, which I could take or leave. (I would rather have it than a Bixby button.)

Overall, it’s a sleek, attractive device, though my “piano black” review unit is more like “mirrored gunmetal,” and it’s one of the slippier, more fingerprint-prone phones I’ve seen in a while. I’d probably like the iridescent purple and blue options better, not to mention the transparent model.

The screen is a 6.4-inch 1080p OLED panel with a slight chin at the bottom and a minimalist waterdrop-style notch at the top. It looks great and also houses an optical in-display fingerprint scanner, which works well enough — if not quite as quickly as Vivo’s most recent implementations. Xiaomi isn’t doing anything cutting edge with its display, but if you’re cool with the small notch, there’s little reason to complain.

The camera can also be safely classified as solid. This is Xiaomi’s first phone to use a triple-lens setup, with a 16-megapixel ultrawide and a 12-megapixel 2x telephoto camera flanking the standard 48-megapixel sensor. The extra resolution is used for pixel-binning and greater light sensitivity at 12 megapixels, but unlike the Honor View 20, there’s no “ultra clarity” mode to bring out extra detail in the 48-megapixel files. You can shoot at full resolution, but it won’t do much beyond giving you unnecessarily large files.I HAVE ABSOLUTELY NO COMPLAINTS ABOUT PERFORMANCE

Again, Xiaomi isn’t competing with high-end competitors with advanced AI-powered HDR implementations. You’re not going to get anything like the Huawei P30’s mind-blowing low-light performance, but its results are broadly satisfying. Colors are well-balanced in daylight, and the night mode is pretty good for what it is. The ultrawide and telephoto cameras aren’t optically stabilized, so they’re not as well-suited to low-light use, but they’re a welcome addition nonetheless.

The Mi 9 is one of the first phones available with Qualcomm’s latest top-end Snapdragon 855 processor, and I have absolutely no complaints about its performance. MIUI, Xiaomi’s version of Android, is extremely smooth on this phone, with the kind of snappy animations and buttery scrolling that I’d normally only expect from OnePlus in this space. Whether I can thank the software or the hardware or — more likely — both, the Mi 9 has been fast and reliable with everything I’ve thrown at it.

MIUI is certainly a radical reskin of Android, and it probably won’t appeal to Pixel or OnePlus purists. But it’s a mature OS in its own right, and I generally find it to be thoughtfully designed and pleasant to use. The Mi 9’s implementation of a full-screen gesture-based navigation system, for example, is the best I’ve seen on Android, though the iPhone-style swipe from the left side of the screen to go back does take a little practice to invoke when using apps with similar gestures.

Xiaomi has also thrown in a couple of features that tend to be first on Chinese phone makers’ cutting room floor. The Mi 9 now has the fastest wireless charging in the world, for example, despite companies like Huawei and Vivo mostly ignoring the feature. Xiaomi sells a 20W wireless charger that’s a pretty great product in its own right; it has an austere white design and a rubberized finish that ensures that even the Mi 9 won’t slip off. For about $15, including a 27W USB-C wired power adapter, it’s a bargain.

The Mi 9 also has the best haptic feedback of any Chinese phone I’ve used. It doesn’t match up to Apple or LG, and it isn’t used extensively throughout MIUI, but it’s a step above what companies like Oppo and OnePlus are doing. While this probably isn’t the most crucial feature in the world for most people, it goes some way to enhancing the sense that you’re getting far more than you’re paying for with the Mi 9.

So what are you missing out on if you do go for the Mi 9 over a more expensive flagship? Not a whole lot. There’s no IP rating for water or dust resistance. There’s only a single mono speaker on the bottom edge of the phone, and it’s pretty bad. There’s no headphone jack, although that isn’t associated with high-end phones any more unless you’re buying from Samsung or LG. The camera isn’t quite world-class, but it’s a perfectly usable three-lens setup.

At €449 (just over $500) for a model with 6GB of RAM and 128GB of storage, the Mi 9 is a ridiculous bargain as long as you live somewhere it’s sold. (Right now, that basically means China or Europe. There’s no Indian release on the horizon, and it doesn’t have broad compatibility with US LTE bands.) Xiaomi has been talking of its ambitions to launch phones in the US for several years, but it still has almost nothing to show for it.

I would say this is the best value in a flagship smartphone in the world, but it’s increasingly hard to say things like that as the global tech market continues to fragment. Instead, all I can say is that Xiaomi has turned in an incredibly solid product at an extremely reasonable price, and now that the company has at least some Western presence, OnePlus and Honor should be on notice.
