Acute heart failure in the 'oldest old' (>=85 years) is characterized by a higher prevalence of preserved ejection fraction and female predominance compared to younger cohorts.
While the incidence and prevalence of heart failure (HF) increase markedly with age, few studies have included data on a large series of patients aged 85 years and older. Clinical and echocardiographic data from 533 patients admitted to a tertiary care hospital for acute HF were obtained. Data from the oldest old (>or=85 years; n=252; mean age, 91.9+/-3.6 years) were compared with data from those aged 65 to 74 years (n=123; mean age, 70.1+/-2.8 years) and 75 to 84 years (n=158; mean age, 79.4+/-2.9 years). Echocardiographic data were consistent with hypertensive remodeling. The proportion of patients with HF and a preserved left ventricular ejection fraction was greatest in the oldest patients (61%) in comparison to patients aged 65 to 74 years (48%) and 75 to 84 years (48%). Approximately three-fourths of the oldest patients were women, and two-thirds of women had a left ventricular ejection fraction >or=50%.
