Prognostic factors in stage D heart failure in the very elderly.
BACKGROUND
The clinical characteristics of frail older patients with advanced heart failure have scarcely been studied.


OBJECTIVE
To describe this population and to identify some prognostic factors of mortality.


METHODS
104 patients aged 75 years and older hospitalized with refractory heart failure were enrolled in a prospective multicentric study.


RESULTS
Mean age was 87.2 +/- 5.3 years. Dyspnea (79.8%), crepitant rales (76.9%) and peripheral edema (73.1%) were particularly frequent. Signs of low cardiac output such as renal insufficiency (46.9%), cutaneous low flow (40.4%), and systolic hypotension (< or =100 mm Hg) (24.3%) were observed less often. Signs of cognitive impairment including anxiety (55.4%), sleep disorders (43.7%) and delirium (35.5%) were frequent. Asthenia and chronic pain were noted in 92.3 and 37.5% of cases, respectively. Mortality rates were 32.7, 59.6 and 71.2% during hospitalization, at 6 months and at 12 months, respectively. According to the multivariate Cox model, six significant factors suggesting a poor prognosis were observed: chronic renal insufficiency, past neuropsychological pathology, long-term treatment with nitrates, presence of edema, low cutaneous flow, and pain. The ability to sit on a chair was the only significant factor associated with a good prognosis.


CONCLUSIONS
Our study identified some clinical and prognostic factors which had been observed in very old patients with refractory heart failure. Pain management has to be a priority in these patients in order to improve their quality of life.
