[Diseases of the circulatory system as a cause of disability in machine-works factories].

The author analyzes a group of 154 invalid subjects where the main cause of invalidity was cardiovascular disease. The investigation was made in a large engineering factory in 1986 and 1987. The group (92% men and 8% women) accounted for 31% of all invalid subjects. The incidence of invalidity on account of cardiovascular diseases per year was approximately 2/1000 workers. Invalidity on account of cardiovascular diseases affects in particular manual male workers, most frequently those aged 50 years and above. Most seriously and most frequently affected are patients with ischaemic heart disease.
