OTTAWA — A 43-year-old woman arrived at a rural Long Island emergency room complaining of sharp stabbing pain under her left breast, which had been on and off for the past 24 hours. She had a history of smoking and high blood pressure, but she had a normal exercise stress test two years earlier and her ECG was normal. Given her symptoms, she could have been having a heart attack or she could simply have gas. Knowing they had to act fast in case she was having a heart attack, clinicians used a point-of-care blood analyzer to test for the biomarker troponin and diagnosed her with a heart attack. She was then flown to a hospital that had a catheterization lab.

TORONTO — Yvonne Felix, an artist and mother, can watch her two young boys play at a park, read restaurant menus and street signs, and work at a job that until recently she would have had to turn down due to low vision caused by her Stargardt's Disease. She's one of many people whose lives have been changed by a high-tech pair of glasses developed by a small Canadian company called eSight eyewear (Ottawa).
