Abstract

Of 3010 participants, 607 had (CVD), with specific pollutants linked to increased risk.

  • Air pollutants chloride ion (Cl), nitrate ion (NO), and particulate matter (PM) are each associated with increased risk of CVD.
  • The three-year mean concentration of Cl is linked to a 1.37-fold risk of CVD.
  • Nitrate ion (NO) exposure is associated with a 1.03-fold risk of CVD.
  • Healthier lifestyles may reduce the risk of CVD related to air pollutants, with varying impacts based on lifestyle scores.
  • For individuals with low, medium, and high healthy lifestyle scores, the risk associated with Cl is 1.34, 1.34, and 1.32 times higher for CVD, respectively.
