Everyday Life, Work Can Pose Pollution RisksThough anyone can be exposed, people who live near road intersections or factories or who direct traffic are particularly at risk, Dr. Luepker said.
In 2004, the American Heart Association issued a scientific statement concluding that exposure to air pollution contributes to cardiovascular illness and mortality. A 2010 update elaborated on those risks.
Short-term exposure can increase the risk of heart attack, stroke, arrhythmias and heart failure in susceptible people, such as the elderly or those with pre-existing medical conditions, according to the statement.
