Pulmonary vascular disease & thromboembolism

Associations of PM2.5 components, residential greenness, and heatwaves with incident venous thromboembolism

Eur J Prev CardiolPublished Prospective cohort study

Authors' conclusion

This study identified that exposure to specific PM2.5 components, low residential greenness, and heatwaves were associated with elevated VTE risk.

Main finding

As reported in the abstract

Incident VTE
Per IQR increase
Hazard ratio (95% CI)
Elemental carbon
1.052(1.005–1.101)
Sulfate
1.064(1.001–1.130)
Ammonium
1.090(1.010–1.176)
Residential greenness
0.944(0.916–0.972)

Per IQR increase, as printed

Heatwaves, HR for incident VTE across heatwave definitions
1.149 (1.137, 1.161) to 1.407 (1.396, 1.417)

Observational data: associations, not effects.

Further findings

Interactions on VTE risk

Significant additive interactions with heatwaves for sulfate and ammonium, not consistently for other components or greenness
Polygenic risk score: significant additive interactions with ammonium and nitrate, multiplicative interaction with residential greenness
