Occupational profile and cardiac risks: mechanisms and implications for professional drivers.

Of the population of 900 drivers, 419 drivers with changes in the circulatory system were enrolled in the study, and the control group consisted of 150 healthy drivers. In both groups there were professional and non-professional drivers. Traffic accidents caused by these drivers were registered over a five-year period. Drivers with cardiovascular diseases and professional drivers were more frequently responsible for accidents than healthy and non-professional drivers. The comparison between the group studied and the controls indicated over a two-fold increase in the number of accidents caused by sick drivers.
