Some behavioural changes in 493 patients after an acute myocardial infarction.

Abstract
Changes in behavior studied were related to smoking, physical activity and weight loss. Personalities of patients were studied by the Eysenck Personality Inventory to find out if there was any relationship between personality factors, extroversion and neuroticism, and changes in behavior. Of the men (66%) and 59% of the women reduced or stopped smoking, 60% of the men and 81% of the women reduced their physical activity and 67% of the men and 56% of the women lost weight. Some significant associations were found between these changes and medical advice given, patients'' views of the value of change in behavior and severity of the illness. Personality factors as assessed were not associated with any observed changes, except in the case of physical activity. Those who increased or decreased their physical activity had a significantly higher mean neuroticism score than those who did not change their behavior in this respect.
