apple watch may spot heart problem but more research needed

by:Sinowon     2020-02-22
A huge study shows that Apple Watches can detect at least sometimes worrying irregular heartbeats --
But experts say more needs to be done to determine whether it is really helpful to use wearable technology to screen for heart problems.
More than 419,000 Apple Watch users signed up for the unusual study, which made the study the largest ever study of people who looked healthy for screening for atrial fibrillation, if not treated, eventually
Researchers at Stanford University reported on Saturday that the watch did not scare crowds and only warned half of the participants --about 2,100 —
They may have problems.
But even among those marked, \"it\'s not perfect \".
Richard Kowach of the American College of Cardiology did not participate in the study.
The person receiving the alert should determine the accuracy of the watch by means of a telemedicine consultation with a research doctor, and then by wearing an EKG patch measuring heart activity next week.
Some people skip the virtual check.
Consult your doctor;
In general, about 57 people seek medical care.
According to preliminary results released at the American Society of Cardiology conference in New Orleans, among those who obtained EKG monitoring through this study, a third person had atrial fibrillation. A-
Dr, chief researcher at Stanford University, says fib tends to come and go, and a week of monitoring may miss some casesMintu Turakhia.
But if the watch detects another irregular heartbeat while someone is wearing the EKG patch, it\'s actually-fib, he said.
\"We believe the study provides very encouraging evidence that the Apple Watch can be used to detect-
Fib and indicate to people when additional monitoring or testing may be required, \"said Dr.
Lloyd Meno, dean of Stanford University School of Medicine
Other heart experts say the Apple-funded study suggests that screening with wearable technology may ultimately be technically feasible, but more research is needed.
\"I will not suggest this to the general population as a whole,\" said Dr.
Valentine Foster, director of the heart of Mount Sinai in New York and former chairman of the American Heart Association, did not participate in the study.
Instead, he would like to see testing in older people with risk factors such as high blood pressure.
What is atrial fibrillation? A-
When the top chamber of the Heart (called atrium) is different from the pumping action of the bottom chamber, fib occurs.
Sometimes the patient feels a rush or a heart beat, but many times they are not aware of the incident.
Sometimes the heart recovers itself.
Other patients are subject to electric shock to restore rhythm or are prescribed to take blood thinners to fight a stroke --
Resulting in untreated blood clotsfib can spur. A-
In the United States, fib causes 130,000 deaths and 750,000 hospital admissions each year. S.
How did the doctor check? A-
FIB is most common in older adults, and other risks include a family history of hypertension or arrhythmias.
But regular screening of people without symptoms is not recommended.
The study has not yet demonstrated that early findings of screening can prevent enough strokes from exceeding the risk of unnecessary testing or over-treatment.
How is apple watch checked?
The mobile app uses optical sensors on certain versions of the watch to analyze pulse rate data.
If it detects enough changes in the beat of more than 48
Within hours, users will receive an irregular warning of cardiac rhythm.
The latest version of the Apple Watch also allows the wearer to press a button to take an EKG and share the reading with the doctor.
Saturday\'s study did not include watches with this function.
Is this new study a good idea to suggest mass screening? No.
The study was designed to tell people how watches compare to a week\'s standard EKG monitoring --
If arrhythmia was found to be not uniform due to screening and the health of the wearer was improved, this would not be the case.
If a-is detected-
It will take years of research to reduce the risk of stroke early.
Since this study did not have a comparison group to get regular EKGs, there is no way to know if the watch missed the heartbeat issue, which gives a false sense of security, Kovacs said.
The confusing low number of alarms may be due to the fact that most participants are young or middle-aged
Older people, not the most dangerousfib, he said.
