Apple Watch Can Detect Hypertension And Sleep Apnea
Nov 15 2017 by Joanne Wise
A study from the University of California San Francisco and Cardiogram has been published, and the findings suggest that the Apple Watch might be an excellent tool for predicting hypertension and sleep apnea. In their first effort, they similarly found that the Apple Watch could detect a serious but often symptomless type of heart arrhythmia, atrial fibrillation. Hypertension - also known as high blood pressure - was detected by the Apple wearable with an accuracy of 82 percent.
Moreover the Apple watch successfully detected sleep apnea in the subjects with an accuracy of 90 percent.
It affects 22million adults in the United States and if left untreated the oxygen deprivation from sleep apnea can result in a growing number of health problems, including high blood pressure, stroke, heart failure, diabetes and heart attacks.
The study was conducted through the Cardiogram app with over 6,00 participants invited to use the Apple Watch over a period time. Meanwhile according to the American Sleep Apnea Association 80% of U.S. adults are considered to have moderate and severe cases of undiagnosed sleep apnea.

I&B Ministry released the final list on November 9 and had taken off these two names, which were recommended by the jury. Jadhav also plans to write to the ministry , too for Nude being removed from the list of films to be screened at IFFI .
As for the Cardiogram study, Ballinger said the results will soon go into the peer review process to validate whether wearables can be used as screeners for major health care conditions.
Sleep apnea is a potentially serious sleep disorder largely associated with heavy snoring in which breathing repeatedly stops.
Another 75 million American adults have high blood pressure (hypertension), according to the Centers for Disease Control (CDC), putting them at risk for heart disease and stroke, the top causes of death in the United States. DeepHeart was trained on data from 70 percent of participants and tested on the 30 percent of participants that weren't the same participants used to collect the data.
Being able to detect sleep apnea and hypertension in the comfort of our homes with just a simple device could be a game-changer in medicine. The study is promising as a way to diagnose health problems in people who may not they have it. The idea is that your Fitbit or AppleWatch's heart rate sensor would automatically, constantly screen for those conditions, and flag you to visit the doctor if the algorithm detected anything abnormal.
