Abstract

Introduction: Exposure to high consistency of Particulate Matter (PM)is a risk factor for cardiovascular disease. In terms of industrially andgeographically, Ahvaz city is exposed to severe pollution, particularlyby dust. Considering the high prevalence of heart disease in the city,studying the impact of particulate matter on cardiovascular diseases toimprove public health appears necessary. Materials and Methods:This retrospective study was done based on hospital records data. Thefollowings were compared based on PM10: prevalence of risk factors,demographic findings and cardiovascular events including unstablepectoral angina, ST-elevation MI, Non ST elevation MI, cardiacfailure, arrhythmia and new cases of arrhythmia, incidence of acutemyocardial infarction and acute cerebral infarction, need forcardiopulmonary resuscitation, worsening of symptoms, and incidence of cardiac arrestduring dusty and cleared days. Abundance statistical comparison of results was carried outbetween contaminated and cleared groups using chi-square test (χ2) by SPSS version 22.Results: 210 cases of 320 examined cases were related to polluted days and 110 cases wererelated to clear days. Statistical analysis of studied cardiac events showed that there is asignificant difference only in occurrence of unstable angina in two groups of clear and polluted (p <0.05). Conclusion: The results of this study showed that exposure to dust can cause to increase the risk of cardiovascular events especially unstable angina.
