It’s incredible how many health issues people have but aren’t aware of. I advise people find doctors and facilities that are friendly towards getting more diagnostics not less. Blood work and other types of tests can help you fix things early.

Cue another 10 minute “Apple Watch Saved My Life!” segment in next year’s Keynote, as is tradition at this point.

Every 20 mmHg increase in your systolic blood pressure, or 10 mmHg increase in diastolic blood pressure, doubles your mortality. And only 23% of people with high blood pressure have it under control.

Pretty massive implications for public health.

I wrote about some of the science behind on-the-wrist blood pressure monitoring and public health implications here:

I am looking forward to this feature, but worry about it's accuracy.

Every time I go to the doctor and they hook me up to a blood pressure monitor, it comes back way high (like 160/90). I then request a manual check and it always comes back normal. I didn't figure this out until after they prescribed me calcium channel blockers (and they didn't do anything). Something about the shape of my arm or something.

Anyway point being that a faulty reading led to me being prescribed meds I did not need. Hoping this doesn't lead to more of the same.

From the article: "it will warn of a potential issue rather than diagnose it"

Seems like lawyer speak for "please don't sue us if we get this wrong" but I suspect the ad campaign for this feature will suggest otherwise.

I think the headline is wrong: at 20:18 in Apple's presentation, the presenter said they expect to notify one million people during the year, not 100 million.

Time to buy stock in companies that produce blood pressure medication?

About as useful as the annoying high volume notifications. No substitute to professional equipment and a doctors visit.
