Heart failure is a significant public health problem. The epidemiology and practice pattern of emergency department(ED)visits for acute decompensated heart failure(ADHF)have not been well characterized. A better description is essential t o highlight areas in which improvements or additional research are needed. We an alyzed all ED visits for ADHF of patients ≥40 years old using the data of the N ational Hospital Ambulatory Medical Care Survey from 1992 to 2001. During this 1 0-year period, an estimated 10.5 million ED visits occurred for ADHF, represent ing 2.9%of all ED visits. The number of ADHF visits increased on average by 18, 500 per year, for a 19.4%absolute increase during the decade. The rate per 1,00 0 United States population was unchanged. The average patient was 74 years old, and patients ≥65 years accounted for 79%of visits. Loop diuretics were adminis tered in 63%and vasodilators in 29%of visits. The ED visit rate per 1,000 Unit ed States population was 53%higher in blacks than in whites(14.2 vs 9.3). In a multivariate model, white race was a significant predictor of hospitalization. I n conclusion, during the past decade, the absolute number of ED visits for ADHF has increased owing to the aging population. Diuretics remain the most common tr eatment. Race-related differences in hospitalization merit additional study.
