Sulphur dioxide is an air pollutant emitted during the combustion of heavy fuels. Power plants, ships and oil refineries are important sources of this pollutant.
In this study, the potential link between exposure to ambient air sulphur dioxide and damages in the epicardial coronary arteries was investigated. A total of 2110 patients hospitalized with a diagnostic of acute coronary syndrome were studied.
It is concluded that exposure to high concentrations of sulphur dioxide (> 8 µg/m3) is a precipitating factor for hospitalization with significant obstructive lesions in patients which suffered acute coronary syndrome. Multivariate analysis shows that an increase of 10 µg/m3 in the concentrations of sulphur dioxide is associated with an increase of 41% in the probability of being increase with significant obstructive lesions in patients with acute coronary syndrome (odds ratio 1.41; 95% confidence interval 1.039-1.931; P = .028).
This study was conducted by the University Hospital of the Canaries, the Izaña Atmospheric Research Centre and other 6 institutions.
