The combined action of the atmospheric pollutants as well as their combination with the meteorological parameters leads to alteration of their effects on the heart. Only for the ozone influence is described a relative independence from the rest of the toxic substances in combined action. Aim is to study the possibility for isolated and combined with the other atmospheric pollutants and conditions of work influence of the levels of particulate matter on the frequency of hospital admissions from acute myocardial infarction (AMI). Data obtained from the medical documentation on laboratory and instrumental investigations were assessed of the 585 patients admitted to the Intensive Care Clinic of University Hospital in Varna with a diagnosis of acute myocardial infarction (AMI) in the period from December 2004 to December 2005. Data from the Regional Inspectorate of Environment and Water and the Regional Inspectorate of Protection and Control of Public Health were analyzed for the mean daily values of the concentrations of ozone, general particulate matter and fine particulate matter (PM) in atmospheric air. The seasonal subordinations described as well as the variability of the effect in combined models of interaction give reason to assume reciprocal influence of the effects on the coronary blood flow of ozone in its combined influence with the other atmospheric pollutants, as well as in its combination with the various meteorological parameters, and from there indirectly with the sun activity. At the same time those effects are determined also by the diverse individual susceptibility of the exposed persons.
