Oh FriedGreenTomatoes2 do you not realise that taking one sentence out of a list entitled‘Challenges’ risks you misunderstanding the context of the whole article?
If you skim read, the Conclusion is the best way of getting the article summary.
‘ Conclusion
Wearable technology has the potential to elevate the routine clinical consultation from a subjective discussion based on patient recollection to a standardised series of objective parameters of both health and quality of life gathered over months or years. Wearable devices have shown some potential application in many cardiovascular diseases, either through disease screening or monitoring; however, the evidence base and the integration of wearable data into clinical cardiology is still in its infancy. Such data could soon help personalise and improve the management of cardiovascular diseases on multiple levels, ultimately resulting in better outcomes on both an individual and a population-wide scale.’
Note the word ‘soon’. This article was published last year, and this is a rapidly growing field, the technology is already being used for some diseases as demonstrated by people who have contributed to this thread, so scoping the potential for patients using smart technology in the areas of medicine where it can help is the right thing to do now.
