title: [Congestive heart failure in the aged. Diagnosis].
abstract: THREE DIAGNOSTIC PITFALLS: The difficulty in diagnosing congestive heart failure in the elderly subject is basically caused by three factors. First, clinical expression is often atypical. Secondly, severity is often underestimated as the prevalence of asymptomatic systolic dysfunction increases with age. Half of all cases of left ventricular systolic dysfunction go unrecognized if clinical signs alone are considered. Finally, the pathophysiology of diastolic dysfunction, which predominates in the over 75 population, is still poorly understood. COMPLEMENTARY EXPLORATIONS: As the clinical signs are the same whatever the mechanism of the ventricular dysfunction, echocardiography is the key exploration for diagnosis and for guiding management. Comorbidity is often a confounding factor preventing precise diagnosis and risk stratification.
