If A-B does not predict heart disease, why bother with it? A clinician's view.

Ray asks the question: 'If A-B does not predict heart disease, why bother with it?' (British Journal of Medical Psychology, 64 (1) 1991). Having worked for several years in prevention of heart attack recurrence, I am inclined to agree with his conclusion that the construct is a trail which should now be abandoned. Grief, hostility and social isolation, fear and work demands have each been implicated in heart disease independently of Type A.
