ABSTRACT
The frequency of Coronary Heart Disease symptoms (questionnaire from G. Rose) and some risk factors were recorded for 314 men in a general practice as part of a preventive screening programme. Simultaneously the number of physician-patient contacts and the total days of work disability were registered. The patients were divided into four social classes. There was a significant increase of symptoms of autonomic nervous disorder and hyperuricemia (p less than 0,025) as well as the number of smokers (p less than 0,001) with descending social class. The same trend was found with the frequency of physician-patient contacts and the total days of work disability (p less than 0,1). Patients with vegetative symptoms showed a mean of 7,2 physician-patient contacts and a work disability of 37,4 days per year. For patients with abnormal ECG findings the rates were 5,6 contacts and 33,4 days of disability per year. There was a significant difference in these rates compared to a control group.
