Key Quotes:
“Cardiac arrest accounts for more than 300,000 deaths in the U.S. each year.”
“When cardiac arrests occur outside of the hospital, victims typically have less than eight percent chance of survival”
"As the levels of particulate matter air pollution increased, more cardiac arrests occurred..for a 10ug/m3 rise in small particle air pollution, there was a four-to-10 percent increase in the number of out-of-hospital cardiac arrests”
“The greatest risks appeared in the warm weather seasons. No differences in effects were seen between men and women, or between middle-aged and older individuals”
"Being indoors may offer only limited protection since small particles can penetrate into buildings and homes"
“The scientists also evaluated levels of ozone, nitric oxide, sulfur dioxide and carbon monoxide, but these showed a much weaker relationship”
“pollution related cardiac arrests occurred during times when the levels were high but still below the current EPA safety threshold”
“The current EPA standard is 35ug/m3.”
“The researchers are now looking for a relationship between out-of-hospital cardiac arrests and traffic flow patterns.”
