RESUMO
Congestive heart failure (CHF) is the most common discharge diagnosis for elderly patients. The survival of elderly (age greater than or equal to 75 years) patients with CHF has not recently been reported, especially with reference to left ventricular ejection fraction (LVEF). A patient database was searched for the diagnosis of CHF and then screened for age greater than or equal to 75, Framingham Criteria for CHF and an LVEF evaluation. Ninety-four men fitted all criteria, including a minimum potential follow-up of 3 years. Life-table analysis was employed to compare their survival experience to an expected survival based on a sex- and age-equivalent subset of the 1980 Census data. Causes of death were determined from autopsy, medical records or death certificates. Mean age at onset of CHF was 82.5. Forty-three per cent had an LVEF greater than or equal to 0.45. There was no difference in the prevalence of potential aetiologies between those with LVEF greater than or equal to 0.45 versus LVEF less than 0.45. Life-table analysis revealed that CHF patients had a worse survival than controls for the first 5 years after diagnosis, attributable primarily to a high first-year mortality (28%) for the CHF group. There was no difference in survival between the LVEF greater than or equal to 0.45 and LVEF less than 0.45 groups.
