    The study evaluated the relationship between air pollution exposure and cardiovascular disease (CVD) incidence in individuals with cardiovascular–kidney–metabolic syndrome.

  • 2

    Among 7400 individuals studied, 21.8% experienced CVD events, including 1212 heart disease cases and 551 strokes over a 7-year follow-up.

  • 3

    Increased exposure to PM1, PM2.5, PM10, and NO2 was associated with higher risks of new-onset CVD, while O3 showed no significant association.

  • 4

    Lower educational attainment was linked to greater risk of incident CVD and heart disease associated with air pollution exposure.

  • 5

    Metabolic syndrome partially mediated the relationship between air pollution exposure and CVD risk among the studied population.
