Background
Heart failure is a major source of morbidity and mortality in the United States. Psychosocial factors have frequently been studied as risk factors for coronary heart disease, but not for heart failure.
Methods and Results
We examined the relationship between psychological status and incident heart failure among 6,782 individuals from the Multi-Ethnic Study of Atherosclerosis (MESA). Anger, anxiety, chronic stress, depressive symptoms, and hostility were measured using validated scales and physician reviewers adjudicated incident heart failure events. Cox proportional hazards models were used to adjust for relevant demographic, behavioral, and physiological covariates. Interactions by age, race, sex, and self-reported health were examined in exploratory analyses. During a mean follow up of 9.3 years, 242 participants developed incident heart failure. There was no association between psychosocial factors and heart failure hazard ratios (95% CI) for highest vs. lowest quartile: anger=1.14 (0.81-1.60), anxiety=0.74 (0.51-1.07), chronic stress=1.25 (0.90-1.72), depressive symptoms=1.19 (0.76-1.85), and hostility=0.95 (0.62-1.42). In exploratory analysis, among the participants reporting fair/poor health at baseline, those reporting high vs. low levels of anxiety, chronic stress, and depressive symptoms had 2-fold higher risk of incident heart failure, but there was no association for those with good/very good/excellent self-reported health.
Conclusions
Overall these psychosocial factors were not significantly associated with incident heart failure. However, for participants reporting poor health at baseline, there was evidence that anxiety, chronic stress, and depressive symptoms were associated with increased risk of heart failure. Future research with greater statistical power is necessary to replicate these findings and seek explanations.
