[Prevalence and management of heart failure in France: national study among general practitioners of the Sentinelles network].
BACKGROUND
Epidemiological data on heart failure's epidemiology in France are scarce and mostly hospital based. The present study's objective is to estimate the prevalence of heart failure (HF) and its management, in subjects aged 60 years and older seen by the French general practitioners (GP).


METHODS
A standardised questionnaire was mailed to 900 GPs of the Sentinelles network, requiring answers for any patient aged 60 years and more, seen on a randomly assigned single day of year 2002. National census and health insurance data were used to estimate prevalence.


RESULTS
434 GPs answered, reporting data for 1797 patients aged 60 years and more. The 214 patients with HF, aged 79 years on average, had been seen by a cardiologist in 95% of cases. Results of an echocardiography was available for 58% of HF patients. Compared to non-HF patients, patients with HF were significantly more dependent, more frequently requiring home visit of the GP and more frequently hospitalised (p < 0.001, age adjusted). All the 42% HF patients with a reported left ventricle ejection fraction lower than 40% were treated with an angiotensin converting enzyme inhibitor or an angiotensin receptor inhibitor. The prevalence of HF among patients aged 60 years and older was estimated at 11.9% in general practice (95% confidence interval: 10.5-13.5), and at 2.19% (1.9-2.5) in the general population. The prevalence increased with age, over 20% in persons aged 80 years and more.


CONCLUSIONS
HF in patients aged 60 years and more seen in general practice in France is characterised by a high prevalence and medical consumption in terms of required number of hospitalisation and GP's home visit. For the GP, the diagnosis of HF relies on the cardiologist more than on an echocardiography. The therapeutic management seems to fit the actual recommendations.
