Heart Attacks

Investigators both in the U.S. and abroad have shown relationships between short- and long-term exposure to air pollution and the increased risk of heart attack and other forms of heart disease. For example, researchers have demonstrated increases in heart attack hospitalization rates in relation to fine particles (PM_2.5) found in haze, smoke and dust. This is particularly true for sensitive groups, such as the elderly, patients with pre-existing heart disease, survivors of heart attack, or people with chronic obstructive pulmonary disease.

The level of environmental risk for heart attacks depends on several factors:

• The amount of pollution in the air

• A person’s exposure to the air pollution

• Overall health

• Know your sensitivity to air pollution.

• Know when air pollution may be bad in your area.

• Plan activities when and where pollution levels are lower, using the air quality index to guide planning.

• Reduce your activity level during times of higher pollution.

• Listen to your body.

• Consult with your health care provider.

• Have your medication with you.

Vermont Tracking provides annual data about hospitalizations for heart attack starting in 2000 and emergency department visits for heart attack starting in 2003. Vermont Tracking also provides data about air quality. Air pollution has been linked to heart disease.
