Sudden cardiac event on a sea-going ship and recognition of a work-related accident
Objectives. Evaluation of the effect of selected work environment factors on a sea-going ship on
the occurrence of a sudden cardiac event and its recognition as a work-related accident.
Background. Sudden cardiac events, myocardial infarction in particular, among crews of seagoing
ships are the most frequent reasons for fatal morbid events. In more than 20% of such
cases, conditions and organization of work at sea are found to be of essential importance.
Problems with certification are related with the assessment of the significance and impact of
specific work environment factors overlapping with classic genetic and environmental factors of
diseases of atherosclerotic origin.
Material and methods. The analysis embraced medical documentation on the state of health
and working conditions at sea concerning 30 crewmembers of Polish sea-going vessels, who had
suffered from sudden cardiac events in the years 1998–2009. The impact of selected work
environment factors on the legitimacy of legal recognition of the event as a work-related accident
was analysed by Fisher’s test and multi-factorial regression.
Results. The presence of classic genetic and environmental risk factors of cardiovascular events
was confirmed in all persons examined. A significant effect on destabilization of the disease,
deterioration of health, and the occurrence of a sudden circulation event was shown to be
strictly related with isometric and dynamic effort, particularly with heat discomfort in the maritime
work environment. This satisfied the legal criteria for recognition of a work-related accident
in half of the cases examined.
Conclusions. Isometric and dynamic effort associated with work under heat stress conditions
may be regarded as a decisive causative factor for a sudden cardiac event and the recognition
of a work-related accident at sea.

Selected work-related nephropathies
Infections, high temperature and many of the toxic substances can cause kidney damage. Acute kidney injury is a well known complication of some work-related diseases, e.g., lead intoxication. Chronic kidney disease can also be caused by some occupational factors. Three work-related nephropathies, in which causal connection with work has been proved, are discussed in this article. There are different risk factors of nephrolithiasis, lead nephropathy and silica nephropathy, but each of them can cause chronic kidney disease. Prevention of these nephropaties seems to be relatively simple. The principles of protection from the toxic effects of heavy metals and silica dust are very specific. The most important prevention of kidney stones is correct fluid intake. In addition to providing adequate quantities of drinking water, it is also important to educate exposed workers and assure enough rest breaks at work. Med Pr 2015;66(4):583–59
