Abstract
PURPOSE: Few studies have examined the interplay between psychosocial and physiological variables in prediction of mortality in heart failure (HF) patients. This study investigated the prospective influence of marital status, social support, depression, and C-reactive protein (CRP) on the mortality of patients with chronic HF. In addition, it examined whether there was a mediating relationship between social support and marital status and whether depression and inflammation influenced one another to predict mortality of HF patients. METHODS: The participants were 220 HF patients, among whom 48 were deceased over an average of 4.60 years. A number of psychosocial and biomedical variables were examined for their associations with mortality and their relationships between each other in hierarchical logistic regression analyses. RESULTS: After adjusting for New York Heart Association (NYHA) class, age, and gender, being unmarried predicted mortality (OR = 2.80, p = 0.004), whereas perceived social support did not. Higher CRP was not associated with depression, and it independently predicted mortality (OR = 1.92, p = 0.030). Depression predicted mortality only in the univariate analysis (OR = 1.02, p = 0.030), but the association was no longer significant either after removing somatic items or after adjusting for covariates. In the combined multivariate model, marital status (OR = 2.20, p = 0.047), CRP (OR = 1.91, p = 0.035), and NYHA class (OR = 2.41, p = 0.001) independently predicted mortality. CONCLUSIONS: Monitoring chronic HF patients who are unmarried, with elevated inflammation, or in higher NYHA class may help identify those at greater mortality risk to implement targeted intervention.
