Eur J Prev CardiolPublished

  • Registry-based cohort study
  • consecutive patients
  • propensity-score adjusted

Authors' conclusion

We found no clear environmental associations with CT-derived coronary obstruction or ischaemia.

Study context

Population
Consecutive patients screened by coronary computed tomography angiography (CCTA) for stable chest pain, 2019–2020420 FFRCT analyses
Participants
2,620 patients
Exposure
Residential air pollution, noise, and green exposure and CT-derived coronary obstruction and ischaemia
Outcome
Obstructive CAD (OCAD, stenosis ≥50%) and abnormal FFRCT (≤80%)

Main finding

As reported in the abstract

Associations of PM2.5, NO2, major road distance, airport distance, vegetation index with OCAD and abnormal FFRCT

Obstructive coronary artery disease (OCAD)

518 (20%)

Abnormal FFRCT

276 (11%)

Observational data: associations, not effects.

Further findings

OutcomeOR (95% CI)
Airport distance, OCAD vs no OCAD (univariable) · OCAD risk, per 1 km, univariable0.983 (0.974–0.992)
Abnormal FFRCT, high-risk patients (Framingham >20%, subgroup) · per 1 km, after PS adjustment0.634 (0.421–0.926)
Airport distance, OCAD vs no OCAD (univariable) — Distance to airport, OCAD vs no OCAD
10.841 (7.869-19.022) km vs. 12.297 (8.691-22.843) km, P < 0.001

Airport distance, OCAD vs no OCAD (univariable)

People living closer to the airport had more cardiovascular (CV) and socio-economic risk factors
