Physical exercise test in the diagnosis of coronary heart disease and arterial hypertension in locomotive engineers

Coronary heart disease and arterial hypertension occupy an important place in the structure of therapeutic pathology in locomotive engineers. It is known that physical activity increases myocardial oxygen demand. Normally, it is compensated by the increase of coronary vessels flow rate. In pathological conditions, coronary circulation reserves are reduced, which leads to myocardial hypoxia and decreased tolerance to physical load. The use of these stress tests in medical examination, in particular bicycle ergometry, allows not only to estimate the state of cardiovascular system, but also to increase the efficiency of detection of the mentioned diseases.

The aim of the present work was to study the level of tolerance to physical load, diagnose coronary heart disease and arterial hypertension in locomotive engineers by bicycle ergometry test data.
