Psychological questionnaire score, cigarette smoking, and myocardial infarction: a continuing enigma

The ability of a group of 94 psychological questions to discriminate between men in whom cigarette smoking was associated with increased risk of myocardial infarction and men in whom smoking was not so associated remains puzzling. Further analyses, controlling for reported alcohol consumption and for a questionnaire item that might reflect physical activity, failed to alter this finding. This interaction of the questionnaire responses with smoking was not found with two other major coronary risk factors, serum cholesterol and systolic blood pressure. Believing that these observations may provide (a) a clue to how cigarette smoking affects risk of myocardial infarction, or (b) some means of identifying greater or lesser susceptibility to the effects of smoking, we invite other investigators to join in the pursuit of this matter. A list of ten selected yes-or-no questions with strong interaction with smoking is provided to assist others in studying this phenomenon; these are similar to ten items on the Minnesota Multiphasic Personality Inventory.
