Key result
A 10 μg/m3 increase in PM2.5 exposure was associated with significant reductions in heart rate variability, including low frequency (-1.66%; 95% CI -2.58% to -0.74%).

Short-term PM2.5 exposure may impair autonomic function; confirms inverse HRV association across pooled observational data.
Meta-Analysis (n=18,667)
Does short-term exposure to particulate air pollution reduce heart rate variability?
Effect estimate: -1.66% change (95% CI -2.58 to -0.74)
This meta-analysis demonstrates a consistent inverse relationship between short-term particulate air pollution exposure and heart rate variability, suggesting a potential mechanism for adverse cardiovascular outcomes.
Pieters et al. (2012) conducted a meta-analysis in Particulate air pollution exposure (n=18,667). Particulate matter (PM2.5) exposure was evaluated on Low frequency heart rate variability (-1.66% change, 95% CI -2.58 to -0.74). A 10 μg/m3 increase in PM2.5 exposure was associated with significant reductions in heart rate variability, including low frequency (-1.66%; 95% CI -2.58% to -0.74%).
