No takes yet. Share an insight, caveat, or question.
May signal higher MI risk from psychosocial factors in women; hypothesis-generating and requires prospective confirmation before any clinical role.
Szklo et al. (1976) conducted a case-control in Myocardial infarction (n=325). Psychosocial factors (educational discrepancy, household crowding, late birth order) vs. Controls hospitalized for other diseases was evaluated on Myocardial infarction. Educational discrepancy was independently associated with myocardial infarction in white women, while household crowding and late birth order were risk factors only when biologic risk factors were present.
