Abstract
Objectives
Trials in chronic heart failure (CHF) include few patients older than 75 years, who represent a large proportion of CHF patients. We evaluated the influence of age on CHF-medication use and of CHF medications on hospitalisation in patients older than 75 years.
Methods
Included in our nested case-control study were 281 patients admitted in 2000 to a French teaching hospital with a main diagnosis of CHF and monitored over a 12-month period. Patient characteristics, medications at discharge, outpatient medications and hospitalisation frequency and duration were compared by means of univariate and multivariate analyses.
Results
Patients older than 75 years (n=150) and 75 years or younger (n=131) were similar with regard to NYHA class and ejection fraction. At discharge, diuretic use was similar in the two groups, but fewer older patients were prescribed angiotensin-converting enzyme (ACE) inhibitors (48% versus 63%, P<0.01) or beta-blockers (19% versus 37%, P<0.001). During follow-up, total re-admission rate and mean number of re-admissions were similar; however, total hospitalisation duration was greater in patients older than 75 years (38±77 days) than in those 75 years or younger (26±59 days) (P<0.01). In patients over 75 years, shorter 12-month hospitalisation duration was associated with prescription of diuretics (P<0.001), ACE inhibitors (P<0.001), beta-blockers (P<0.01) and digitalis (P<0.05).
Conclusions
Recent advances in CHF therapy are generally applied less to patients over 75 years of age—associated with longer annual hospitalisation duration in this population. Appropriate CHF medications at hospital discharge appear to reduce annual hospitalisation duration in patients older than 75 years.
