Implication

Time-series analysis reveals elevated mortality from ambient air particles in individuals with heart failure or acute lower respiratory disease, indicating specific cardiorespiratory vulnerabilities.

Key Points

To identify specific cardiovascular and respiratory conditions that increase susceptibility to acute mortality from ambient air particle exposure.
Linked daily ambient particulate measures (including coefficient of haze and sulfates) with nonaccidental deaths in Montreal, Canada, from 1984 to 1993.
Identified subjects' preexisting cardiovascular and respiratory diseases using provincial universal medicare billing and prescription records.
Estimated associations between daily particle levels and daily mortality across disease subgroups using Poisson regression time-series models with multiday averages.
Daily mortality increased linearly with particle concentrations for acute lower respiratory diseases (mean percent change [MPC] = 5.09%; 95% CI, 2.47–7.79%), chronic coronary artery disease (MPC = 2.62%; 95% CI, 0.53–4.75%), and congestive heart failure (MPC = 4.99%; 95% CI, 2.44–7.60%) per interquartile range increase in coefficient of haze.
No persuasive evidence of increased daily mortality was observed for individuals with chronic upper respiratory diseases, airways disease, cerebrovascular disease, acute coronary artery disease, or hypertension.
Associations remained positive after adjustment for gaseous pollutants and exhibited stronger effects during the summer season.
