Examined were 225 sailors of 10 sister large-capacity vessels belonging to Russian shipowners. Clinical condition and the cardiovascular function of the sailors were assessed on months 1, 3 and 6 using physical methods and ECG, provocative tests and clinical condition scoring scale. Physical activity was evaluated. Incidence of CCI symptoms and clinical signs in sailors was significantly in excess of the all-Russian value. Clinical condition of sailors with CCI symptoms and clinical signs was noted to grow worse by the end of voyage. Factors contributing to CCI development and aggravation during long voyages were identified.
