Heart Facts

  • Heart disease and stroke are the first and fourth leading causes of death in the U.S.
  • Air pollution can affect heart health and can trigger heart attacks and strokes that cause disability and death.
  • One in three American adults has heart or blood vessel disease and is at higher risk from air pollution.

EPA is raising awareness of heart disease and its link to air pollution and other environmental factors as a partner in Million Hearts, a national initiative to prevent heart attacks and strokes.
