EVIDENCE is stronger than ever that pollution from industry, traffic and power generation causes strokes and heart attacks, and people should avoid breathing in smog, according to the American Heart Association.
Fine particulate matter from burning fossil fuels such as gasoline, coal and oil is the clearest offender, the group said.
"Particulate matter appears to directly increase risk by triggering events in susceptible individuals within hours to days of an increased level of exposure, even among those who otherwise may have been healthy for years," said Dr Robert Brook of the University of Michigan in Ann Arbor, who headed the group writing the report.
A review of six years of medical research also showed strong evidence that pollution can help clog arteries, and a "small yet consistent" association between short-term exposure to air pollution and premature death.
"The foremost message for these high-risk groups remains that they should work to control their modifiable risk factors - blood pressure, cholesterol, diabetes, smoking," Brook said.
