| Abstract | In a time series studies, air pollution was associated with specific cardiovascular mortality, but little is known about the short-term nitrogen dioxide (NO2) effects on acute heart attack risk. The objective of the study was to estimate association between NO2 exposure and emergency hospital admission for myocardial infarction and unstable angina pectoris in Kaunas within 2005-2006 periods. Associations were assessed using the case-crossover method and multivariate logistic regression. Mean daily levels of NO2 were related to the daily number of hospital admissions for heart attack. The relative risk for increase of heart attack admissions, evaluated at NO2 tertiles of day of admission and 2 days prior to the data of admissions were as follows: 1; 2.22, 95% CI 1.32-3.76; 2.84, 95% CI 1.70-4.77 and 1; 1.70, 95% CI 1.03-2.82; 2.10, 95% CI 1.27-3.45. The hospital admission odds ratios for each 10 mu g/m(3) increase in NO2 level was associated with a risk of heart attack admissions of 28% (OR=1.28, 95% Cl 1.11-1.48; p<0.001). These findings suggest that higher ambient NO2 levels might bee associated with increase of heart attack risk. |
