• This study aimed to assess the effect of air pollution and weather conditions on the frequency of hospital admissions due to acute coronary syndrome (ACS) in the population of Bialystok, known as the capital of the Green Lungs of Poland. The study analyzed the medical records of 2,645 patients living within the borders of Bialystok who were treated for ACS between 2009 and 2017 and the data on air pollutants—nitrogen dioxide (NO2), sulfur dioxide (SO2), and particulate matter with a diameter of 2.5 μm or less (PM2.5) and 10 μm or less (PM10)—and the basic meteorological factors (temperature, humidity, and atmospheric pressure). A time-stratified case-crossover study design was applied to assess the effects of particulate matter, the concentration of gases, and weather conditions on ACS. The number of patients admitted for ST-segment elevation myocardial infarction, non-ST-segment elevation myocardial infarction (NSTEMI), and unstable angina (UA) was 791, 999, and 855, respectively. The daily concentration norm for PM2.5 recommended by the World Health Organization (WHO) was exceeded in 692 days (i.e., 24.58% of the observation period). The significant increase in the number of ACS hospitalizations was associated with an interquartile-range increase in NO2 concentration, with an odds ratio of 1.08 (95% confidence interval (CI): 1.02–1.15, P = 0.01), 1.09 (95% CI: 1.01–1.18, P = 0.03), and 1.11 (95% CI: 1.00–1.22, P = 0.048) for patients with ACS, NSTEMI, and UA, respectively. The study showed that the effects of air pollution and weather conditions on the number of ACS hospitalizations are also observed in cities with moderately polluted or good air quality. NO2 was identified as the main air pollutant affecting the incidence of ACS. •The first case-crossover study on the air pollution and acute coronary syndromes in Poland, Europe.•The effect of air pollution on the incidence of acute cardiac events is also observed in cities where World Health Organization norms of air pollution are not often exceeded.•Short-term exposure to NO2 was associated with an increase in prevalence of acute coronary syndromes.
