The authors hypothesized that a possible reason for this inconsistency could be represented by the differences between the clinical trial selected populations and the general population and, therefore, they designed a study aimed to compare characteristics of patients referred to their heart failure outpatient clinic with those of patients enrolled in large clinical intervention studies on heart failure pharmacological treatment.
