Perfect storm: concurrent stress and depressive symptoms increase risk of myocardial infarction or death.

ABSTRACT: Depression and stress have each been found to be associated with poor prognosis in patients with coronary heart disease. A recently offered psychosocial perfect storm conceptual model hypothesizes amplified risk will occur in those with concurrent stress and depressive symptoms. We tested this hypothesis in a large sample of US adults with coronary heart disease.Participants included 4487 adults with coronary heart disease from the REasons for Geographic and Racial Differences in Stroke study, a prospective cohort study of 30,239 black and white adults. We conducted Cox proportional hazards regression with the composite outcome of myocardial infarction or death and adjustment for demographic, clinical, and behavioral factors. Overall, 6.1% reported concurrent high stress and high depressive symptoms at baseline. During a median 5.95 years of follow-up, 1337 events occurred. In the first 2.5 years of follow-up, participants with concurrent high stress and high depressive symptoms had increased risk for myocardial infarction or death (adjusted hazard ratio, 1.48 [95% confidence interval, 1.08-2.02]) relative to those with low stress and low depressive symptoms. Those with low stress and high depressive symptoms (hazard ratio, 0.92 [95% confidence interval, 0.66-1.28]) or high stress and low depressive symptoms (hazard ratio, 0.86 [95% confidence interval, 0.57-1.29]) were not at increased risk. The association on myocardial infarction or death was not significant after the initial 2.5 years of follow-up (hazard ratio, 0.89 [95% confidence interval, 0.65-1.22]).Our results provide initial support for a psychosocial perfect storm conceptual model; the confluence of depressive symptoms and stress on medical prognosis in adults with coronary heart disease may be particularly destructive in the shorter term.

Project description:BACKGROUND: The use of cardiovascular health services is greater among patients with depressive symptoms than among patients without. However, the extent to which such associations between depressive symptoms and health service utilization are attributable to variations in comorbidity and prognostic disease severity is unknown. This paper explores the relationship between depressive symptoms, health service cardiovascular consumption, and prognosis following acute myocardial infarction (AMI). METHODS: The study design was a prospective cohort study with follow-up telephone interviews of 1,941 patients 30 days following AMI discharged from 53 hospitals across Ontario, Canada between December 1999 and February, 2003. Outcome measures were post discharge use of cardiac and non-cardiac health care services. The service utilization outcomes were adjusted for age, sex, income, comorbidity, two validated measures of prognosis (cardiac functional capacity and risk adjustment severity index), cardiac procedures (CABG or PTCA) and drugs prescribed at discharge. RESULTS: Depressive symptoms were associated with a 24% (Adjusted RR:1.24; 95% CI:1.19-1.30, P < 0.001), 9% (Adjusted RR:1.09; 95% CI:1.02-1.16, P = 0.007) and 43% (Adjusted RR: 1.43; 95% CI:1.34-1.52, P < 0.001) increase in total, cardiac, and non-cardiac hospitalization days post-AMI respectively, after adjusting for baseline patient and hospital characteristics. Depressive-associated increases in cardiac health service consumption were significantly more pronounced among patients of lower than higher cardiac risk severity. Depressive symptoms were not associated with increased mortality after adjusting for baseline patient characteristics. CONCLUSION: Depressive symptoms are associated with significantly higher cardiac and non-cardiac health service consumption following AMI despite adjustments for comorbidity and prognostic severity. The disproportionately higher cardiac health service consumption among lower-risk AMI depressive patients may suggest that health seeking behaviors are mediated by psychosocial factors more so than by objective measures of cardiovascular risk or necessity.

Project description:IntroductionAcute myocardial infarction (MI) is a potentially fatal condition, leading to high psychological distress and possibly resulting in the development of depressive symptoms and posttraumatic stress symptoms (PTSS). The aim of this study was to investigate the association of clusters of positive psychosocial factors (resilience, task-oriented coping, positive affect and social support) with both MI-induced depressive symptoms and PTSS, independent of demographic factors.MethodsWe investigated 154 consecutive patients with MI, 3 and 12 months after hospital discharge. All patients completed the short version of the German Resilience Scale, the Coping Inventory for Stressful Situations (CISS), the Enriched Social Support Inventory (ESSI) and the Global Mood Scale (GMS). The level of interviewer-rated MI-induced posttraumatic stress disorder (PTSD) symptoms at 3- and 12-months follow-up was evaluated through the Clinician-Administered PTSD Scale (CAPS). Depressive symptoms were assessed at 3- and 12-month follow-up with the Beck Depression Inventory (BDI-II).ResultsThree different clusters were revealed: (1) lonely cluster: lowest social support, resilience and average task-oriented coping and positive affect; (2) low risk cluster: highest resilience, task-oriented coping, positive affect and social support; (3) avoidant cluster: lowest task-oriented coping, positive affect, average resilience and social support. The clusters differed in depressive symptoms at 3 months (F = 5.10; p < 0.01) and 12 months follow-up (F = 7.56; p < 0.01). Cluster differences in PTSS were significant at 3 months (F = 4.78, p < 0.05) and 12 months (F = 5.57, p < 0.01) follow-up. Differences in PTSS subscales were found for avoidance (F = 4.8, p < 0.05) and hyperarousal (F = 5.63, p < 0.05), but not re-experiencing, at 3 months follow-up. At 12 months follow-up, cluster differences were significant for re-experiencing (F = 6.44, p < 0.01) and avoidance (F = 4.02, p < 0.05) but not hyperarousal.DiscussionThe present study contributes to a better understanding of the relationships among different positive psychosocial factors, depressive symptoms and PTSS following acute MI. Future interventions may benefit from taking into account positive psychosocial factors to potentially reduce patients' depressive symptoms and PTSS after MI.

Project description:BACKGROUND:Depressive symptoms is associated with adverse cardiovascular outcomes in patients with myocardial infarction (MI), but the underlying mechanisms are unclear and it remains unknown whether subgroups of patients are at a particularly high relative risk of adverse outcomes. We examined the risk of new cardiovascular events and/or death in patients with depressive symptoms following first-time MI taking into account other secondary preventive factors. We further explored whether we could identify subgroups of patients with a particularly high relative risk of adverse outcomes. METHODS AND RESULTS:We conducted a prospective population-based cohort study of 897 patients discharged with first-time MI between 1 January 2009 and 31 December 2009, and followed up until 31 July 2012. Depressive symptoms were found in 18.6% using the Hospital Anxiety and Depression Scale (HADS-D?8). A total of 239 new cardiovascular events, 95 deaths, and 288 composite events (239 new cardiovascular events and 49 deaths) occurred during 1,975 person-years of follow-up. Event-free survival was evaluated using Cox regression analysis. Compared to the 730 patients without depressive symptoms (HADS-D<8), the 167 patients with depressive symptoms (HADS-D?8) had age- and sex-adjusted hazard ratios [HR] (95% confidence interval [CI]) of 1.53 (95% CI, 1.14-2.05) for a new cardiovascular event, 3.10 (95% CI, 2.04-4.71) for death and 1.77 (95% CI, 1.36-2.31) for a composite event. The associations were attenuated when adjusted for disease severity, comorbid conditions and physical inactivity; HR?=?1.17 (95% CI, 0.85-1.61) for a new cardiovascular event, HR?=?2.01 (95% CI, 1.28-3.16) for death, and HR?=?1.33 (95% CI, 1.00-1.76) for a composite event. No subgroups of patients had a particularly high risk of adverse outcomes. CONCLUSIONS:Depressive symptoms following first-time MI was an independent prognostic risk factor for death, but not for new cardiovascular events. We found no subgroups of patients with a particularly high relative risk of adverse outcomes.
