Utilisation of medications recommended for chronic heart failure and the relationship with annual hospitalisation duration in patients over 75 years of age. A pharmacoepidemiological study.

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.
