The relationship between ambient air pollutant exposures and acute ischaemic stroke was evaluated based on the timing of symptom onset. A time-stratified, case-crossover analysis was conducted among 520 patients who had ischaemic stroke admitted to the Second Hospital of Tianjin Medical University (Tianjin, China) between 4/1/2018 and 3/31/2019. Daily air pollutant concentrations of PM2.5, PM10, SO2, NO10, CO, and O3were obtained from fixed-site monitoring stations. Overall, a higher risk of ischaemic stroke was found between April and September. During this period PM10 was associated with an increased risk of ischaemic stroke among patients between 34 and 70 yearsr old. Positive associations were observed between PM10, O3, and ischaemic stroke occurrence among those with hyperlipidaemia.
