Abstract P379: Multimorbidity in Heart Failure: The Impact of Number and Type of Comorbid Conditions on Outcomes

Background: Multimorbidity is common in heart failure (HF); however the impact of the number and type of comorbid conditions on outcomes remains uncertain. Methods: Olmsted County, MN residents with incident HF from 2000-2010 were identified. The prevalence of 16 chronic conditions defined by the US Department of Health and Human Services was obtained at the time of HF. The chronic conditions were classified into 3 groups: cardiovascular (CV), other physical and mental. Cox regression was used to determine associations of the number of each type of condition and each individual condition with death or hospitalizations within 30 days or 1 year. Results: 1,382 incident HF patients (mean±SD age 75±14, 46% male) were identified. The mean number of conditions per patient was 2.6±1.5, 1.2±1.1 and 0.30±0.61 for CV, physical and mental conditions, respectively. After a mean follow-up of 4.4 years, 814 deaths occurred while 301 hospitalizations occurred within 30 days and 774 within 1 year. The number of physical ...
