Abstract

The purpose of this dissertation was to evaluate the association of psychological distress with cardiac disease, events, and mortality. Specific aims were to: 1) to evaluate the association between hostility level and recurrence of acute coronary syndrome (ACS) and all-cause mortality in patients with coronary heart disease (CHD); 2) to evaluate the psychometric properties of the Brief Symptom Inventory (BSI) hostility and anxiety subscales in a group of incarcerated participants at high risk of cardiovascular disease; and 3) to evaluate the association of patient and caregiver psychological state with quality of life in both patient and caregiver, and postoperative complications after cardiac surgery.

Specific aim one was addressed through a secondary analysis of data collected during the Patient Response to Myocardial Infarction following a Teaching Intervention Offered by Nurses trial to determine whether hostility was a predictor of ACS recurrence and mortality. Hostility was common after ACS and predicted all-cause mortality. Hostility did not predict recurrent ACS. Specific aim 2 was addressed in a secondary analysis of baseline data from a randomized controlled trial in male prisoners. Participants completed the BSI at baseline prior to the intervention. Internal consistency reliability was good for both subscales (Cronbach’s alpha - hostility 0.83, anxiety 0.81). Items from the two dimensions were analyzed together using exploratory factor analysis with varimax rotation. Two dimensions, anxiety and hostility, were identified. Construct validity was supported; those with high anxiety and hostility reported a greater number of days where their self-reported health was rated as fair or poor. Those prisoners with less perceived control had higher levels of anxiety and hostility. Specific aim 3 was addressed through a prospective, descriptive correlational study that measured patient and caregiver anxiety, hostility and depressive symptoms, at baseline to determine whether these predicted quality of life using a multilevel dyadic analysis; and to evaluate the association of baseline anxiety, hostility and depressive symptoms and quality of life with postoperative complications and mortality. Anxiety, hostility, and depressive symptoms were common in both cardiac patients and their caregiver. Psychological state influenced quality of life in both dyad members, but was not associated with complications.
