More deaths reported as extreme heat bakes U.S. coasts

The death toll is rising as life-threatening heat continues to bear down on both U.S. coasts. Officials are investigating at least 11 fatalities in Washington state and Oregon that may be tied to the extreme temperatures. 

"People who have existing pre-existing medical problems like hypertension and diabetes, high cholesterol, even mental health disorders are at risk," said Dr. Michael Redlener, an emergency medicine physician at Mount Sinai Hospital.   Through the heat wave, Washington state reported more than 1,300 emergency room visits for heat-related illnesses. Across the border with Canada, the Vancouver Police Department reported nearly 100 sudden deaths since Friday — the vast majority likely related to the heat.
