Abstract

OBJECTIVE: This prospective study examined sex differences in illness intrusiveness and in baseline predictors of illness intrusiveness in cardiac patients' 1-year postcardiac event. METHODS: Patients diagnosed with a myocardial infarction (MI) or unstable angina (UA) completed a baseline questionnaire during their hospitalization (139 men and 104 women). Eighty-one men and 67 women completed the follow-up questionnaire 1-year postcardiac event. The questionnaire included measures of illness intrusiveness in three life domains, depressive symptomatology, social support, medical information, risk factors for heart disease, and sociodemographic information. RESULTS: A MANCOVA with the three Illness Intrusiveness subscales as dependent variables, sex as the between-group factor, and partnership status as a covariate found a sex effect for the Intimacy subscale, but not for the Instrumental and the Relationships/Personal Development subscales. Men reported more intrusiveness in the Intimacy domain of their life as compared to women. After controlling for sociodemographic factors and risk factors for heart disease, hierarchical regressions indicated sex differences in baseline predictors of 1-year follow-up illness intrusiveness in the three life domains. For men, being satisfied with support from partner at baseline was associated with less intrusiveness in the Instrumental Life domain 1 year after the cardiac event. For women, surprisingly, more satisfaction with support from their partner at baseline was associated with more intrusiveness in their intimate lives 1 year after their cardiac event. In addition, emotional symptoms of depression at baseline were predictive of increased illness intrusiveness in Relationship/Personal Development and Intimacy domains for men and in Instrumental and Intimacy domains for women. CONCLUSION: Support from partner may have a differential impact for men and women after a cardiac event. Depressive symptomatology during initial hospitalization, particularly emotional symptoms, is a prominent indicator of illness intrusiveness for both sexes 1 year after the cardiac event
