Health care economist Aaron Carroll is here to rain on the parade surrounding the new Apple Watch and its heart-monitoring features.

The details: Writing in the New York Times, Carroll says the risk of false positives — the watch telling people they have a heart irregularity that isn’t really there — is too high.

  • Experts have previously recommended against widespread heart monitoring, Carroll notes.
  • And the Apple Watch will primarily appeal to a low-risk population to begin with.

“This is one of the major problems with such a device. The people most in need of it, those who might benefit from tests and distance monitoring, are the least likely to get it. If we truly believed this was a medical test beneficial to the general population, insurance should pay for it. No one is suggesting that should happen,” he writes in NYT.

China said Monday that it will ban entry to Sens. Marco Rubio (R-Fla.) and Ted Cruz (R-Texas) over their criticisms of human rights abuses in Xinjiang, the AP reports.

The big picture: The move seems to be retaliatory after the U.S. announced sanctions on four Chinese officials for human rights abuses against Uighur Muslims and other ethnic minorities in the region last week.
