Nearly 5 million Americans have heart failure (HF) today, with an incidence approaching 10 per 1000 population in persons older than 65 years of age; approximately 50% of these patients are women (Figure 1).1 In 2000, 62.3% of all HF mortalities occurred among women; 20% of those patients died within 1 year of their diagnosis, and less than 15% of women survive more than 8 to 12 years after diagnosis.2 These results notwithstanding, the Framingham study recently noted that the age-adjusted rates of HF are higher among men, with no significant change in this rate over a 50-year period.3 Among women, the incidence of HF has decreased by 31% to 40% in the decades after 1950.

HF is the reason for at least 20% of all hospital admissions in persons older than 65 years, and over the past decade, hospitalizations for HF have increased by 159%. Women who have been hospitalized with HF have less improvement in physical health status and perceive their quality of care to be lower than that of their male cohorts.4 Of the thousands of patients disabled from HF within 6 years of their diagnosis, 46% are adult women compared with only 22% of men. In 1997, an estimated $5501 was spent for every hospital-discharge diagnosis of HF, and another $1742 per month was required to care for each patient after discharge. Gender has been shown to be an important determinant of hospital length of stay, hospital charges, . . . [Full Text of this Article]
