Congestive heart failure is a frequent disorder with an estimated prev
alence of 0.4-2% in the general population. Despite recent advances in
our understanding of the pathophysiology of this disorder and new dev
elopments in its treatment, the prognosis of heart failure remains poo
r. All patients with heart failure should undergo diagnostic evaluatio
n to determine the type of cardiac dysfunction, establish its etiology
and orient treatment. Angiotensin converting enzyme (ACE) inhibitors,
diuretics and digoxin are the standard therapy for chronic congestive
heart failure caused by systolic dysfunction. ACE inhibitors are indi
cated in all stages of heart failure, even in asymptomatic patients. D
iuretics should be added in the presence of fluid retention. Digoxin r
emains an important component in the management of refractory symptoms
and atrial fibrillation. Symptomatic improvement and reduced morbidit
y have been shown with all these drugs. However, improved survival has
been documented for ACE inhibitors only. Currently, numerous drugs wi
th different mechanisms of action are being evaluated in ongoing clini
cal trials. Promising results have been published, mainly with beta-re
ceptor blocks and newer positive inotropic substances. Rapidly growing
evidence from basic research will advance our understanding of heart
failure and hopefully pave the way for new preventive and therapeutic
strategies in the near future.
