Evaluation of the circulatory system in a population of seamen and deep-sea fishermen based on the analysis of blood circulation by means of Wezler and Boeger's method.

Abstract

1,397 seamen and deep-sea fishermen were examined, their polycardiographic records were evaluated. Their mean age was 44.1 +/- 9.3 years, while the period of the service at sea averaged 22.8 +/- 7.1 years. Using Wezler and Boeger's method, physical analysis of the blood circulation was carried out. Carotid arteriograms were evaluated with Donzelot's method. Electrocardiograms were evaluated following Minnesota Code 1982. In 587 people (42.0%) pathological changes in the blood circulation were revealed. In 260 people (18.6%) ECG records were abnormal. In 112 people (8%) border hypertension was recorded and in 486 people (13.3%) arterial hypertension was diagnosed. Abnormal speed of the central pulse wave, air chamber elasticity coefficient and peripheral resistance occurred in 35%, and abnormal carotid arteriograms were registered in 34.5% of the men examined. The data of the survey indicated that the risk of diseases of the circulatory system was high in the occupational group examined.
