Abstract
Comment on "Effect of short-term fluctuations in outdoor air pollution on the number of hospital admissions due to acute myocardial infarction among inhabitants of Kraków, Poland".
Highlights
In their important study, Konduracka et al[5] used a time‐series regression analysis to examine asso‐ ciations between daily counts of hospital admis‐ sions for myocardial infarction (MI) and short ‐term elevation in averaged daily city‐level con‐ centrations of air pollution from fixed monitoring stations
Exposure to air pollution particulate matter (PM) is correlated with subclinical pathologies underlying cardiovascular disease, including systemic inflammation and ox‐ idative stress, atherosclerosis, thrombosis, endo‐ thelial dysfunction, hypertension, cardiac remod‐ eling, and arrhythmia.[2]
The units of analysis are days; it is reasonable that the only potential confounders are variables that could change from day to day with air pollution levels
Summary
Konduracka et al[5] used a time‐series regression analysis to examine asso‐ ciations between daily counts of hospital admis‐ sions for myocardial infarction (MI) and short ‐term elevation in averaged daily city‐level con‐ centrations of air pollution from fixed monitoring stations.
