[The prevalence and clinical characteristics of heart failure in a population sample of Calabria].
Two-hundred and fourteen patients with congestive heart failure were identified over a six-month period in the general practice of 29 GPs covering an adult population of 29,959 subjects residing in the region of Calabria, in southern Italy, with an overall prevalence of 7 per 1000. Males represented 52% of the cases and females 48%, with a median age of 75 years. On average, the condition was first diagnosed 41 months before the present examination. Patients generally had a high body mass index (28 kg/m2). Patients were classified as follows in the NYHA classification: 9.4% in class I, 45.3% in class II, 39.2% in class III, 6.1% in class IV. Hypertension, either alone or associated with ischemic heart disease (totally about 75% of cases), was the most common etiology, while COPD was the most commonly associated chronic condition. Clinical symptoms and signs were used to classify patients in a simplified version of the Boston score which was reported in 48% of cases as definite, 12% as possible, 6% as improbable and 34% as absent. A specific treatment was already ongoing in 97% of patients. The most commonly administered drugs were diuretics (83%), ACE-inhibitors (77%), and digitalis (67%). This three-drug combination (alone or with other drugs) covered 46% of patients. A comparison of four predefined typologies of treatment against the Boston score suggested that at least part of the outcome in classifying patients using this procedure was due to pathomorphosis of the syndrome induced by early pharmacological treatment.
