The Apple Watch began arriving in homes and businesses across America on Friday. And in New Orleans, one doctor immediately strapped it to his patient's wrist. "We need to fundamentally change behavior," says that doctor — Richard Milani. "And the Apple Watch has the potential to [do] it." Milani is the Chief Clinical Transformation Officer at Ochsner Health System, and overseeing what the hospital calls a first-of-its-kind trial: Giving Apple Watch to patients who struggle with high blood pressure, and seeing if it prompts them to take their medication, to make positive changes in lifestyle, and simply, to just get up and move around.
