A/B behaviour pattern not correlated with other coronary risk factors in industrial plant populations.

The behaviour pattern was assessed in two groups of middle aged men, 157 subjects selected randomly from a coronary risk group of 1553 subjects and 83 respondents for physical fitness testing. The number of risk factors i.e. smoking, hypertension, hypercholesterolemia, angina pectoris by chest-pain questionnaire and positive family history was higher in the physical fitness testing respondents than in randomly selected subjects, the difference being highest for A Type men. No correlation between the behaviour pattern and prevalence of RF was found. Subjects with higher score of neuroticism in EPI were the heaviest smokers.
