Air pollution increases heart attacks in nonsmokers, study finds

Air pollution increases heart attacks in nonsmokers

Air pollution is associated with significant increases in heart attacks among nonsmokers, according to a study presented at the European Society of Cardiology Congress 2022, held from Aug. 26 to 29 in Barcelona, Spain.

Insa de Buhr-Stockburger, M.D., from the Berlin Brandenburg Myocardial Infarction Registry, and colleagues examined the association between nitric oxide, particulate matter (PM10), and weather variables with the incidence of myocardial infarction (MI) in Berlin. The analysis included 17,873 MI cases from 2008 to 2014.

The researchers found a highly significant, independent association between overall MI incidence and same-day mean values of nitric oxide concentrations and with the average PM10 concentration over the preceding three days. MI incidence variation with same-day nitric oxide was 3.2 percent, and variation with PM10 in the preceding three days was 4.8 percent. There was an inverse relationship between daily peak ambient temperature and MI incidence. No associations were seen for sunshine duration and precipitation. Nitric oxide and PM10 pollution did not affect MI incidence in current smokers.

"The study indicates that is a risk factor for and more efforts are needed to lower pollution from traffic and combustion," de Buhr-Stockburger said in a statement.

"Causation cannot be established by an observational study. It is plausible that is a contributing cause of myocardial infarction, given that and PM₁₀ promote inflammation, atherosclerosis is partly caused by inflammatory processes, and no associations were found in smokers."
