[A comparative analysis of different approaches to identifying cardiovascular diseases in coal miners during medical
Abstract:
An expert evaluation of identifiability of cardiovascular diseases was carried out together with a clinical and functional examination of certain groups of miners of basic underground occupations at different ages and lengths of service, that showed a high incidence of cardiovascular diseases along with a low informative value of methodical approaches, indices and criteria used for their diagnosis in conducting preliminary and periodic health check-ups. To improve the quality of diagnosis of diseases of the circulatory system it is necessary that standardized methods of investigation should be employed together with consistent indices of high informative value as well as a purposive training of physicians.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
