ABSTRACT

A method for quantitative evaluation of the probability for ischaemic disease of the heart in epidemiological studies is recommended and the state of risk is determined by riskogram, including 3 parts 1. Assessment of the electrocardiographic changes after Minnesota code. 2. Integral quantitative interpretation of ECG-changes with the data from the Rose test. 3. Classified quantitative assessment of the probability for ischaemic disease of the heart. The quantitative interpretation of the probability for ischaemic disease of the heart allows the use of various statistical methods, mathematical models and computer processing of data, received at the epidemiological studies. By tracing the dependences "dose-effect" and "dose-response" the maximum admissible duration of the length of service could be predicted in specific conditions of professional exposure, in order to prevent injury of the cardiovascular system from harmful industrial factors.
