New Study Finds Air Pollution May Trigger Heart Attacks

The American Journal of Epidemiology has published a report finding a dramatic correlation between spikes in air pollution and hospital admissions for heart attacks, suggesting that high-pollution days may trigger heart attacks in some people.

The study examined data on more than 10,000 heart attacks between 2002 and 2005. When the heart attack data were correlated with changes in air pollution levels, researchers in Italy found that an increase of 10 micrograms per cubic meter of fine particulate matter in the air correlated with a 0.01 percent increase in hospitalizations for heart attacks over the next two days. The researchers found a similar correlation between heart attacks and increases in carbon monoxide and nitrogen dioxide. Click here to read more . . . .
