Rurality and event-free survival in patients with heart failure

Heart Lung. 2010 Nov-Dec;39(6):512-20. doi: 10.1016/j.hrtlng.2009.11.002.

Abstract

Background: Evidence of health disparities between urban and rural populations usually favors urban dwellers. The impact of rurality on heart failure (HF) outcomes is unknown.

Objective: We compared event-free survival between HF patients living in urban and rural areas.

Methods: In this longitudinal study, 136 patients with HF (male, 70%; age, mean ± SD 61 ± 11 years; New York Heart Association class III/IV, 60%) were enrolled. Patients' emergency department visits for HF exacerbation and rehospitalization during follow-up were identified. Rural status was determined by rural-urban commuting area code. Survival analysis was used to determine the effect of rurality on outcomes while controlling for relevant demographic, clinical, and psychosocial variables.

Results: Rural patients (64%) had longer event-free survival than urban patients (P = .015). Rurality (P = .04) predicted event-free survival after controlling for age, marital status, New York Heart Association class, medications, adherence to medications, depressive symptoms, and social support.

Conclusions: Rural patients were less likely than their urban counterparts to experience an event. Further research is needed to identify protective factors that may be unique to rural settings.
