Although it is known that some patients with heart failure have no clinical or radiographic signs of congestion, despite markedly elevated filling pressures and depressed cardiac output, this phenomenon has received very little attention. The lack of understanding this phenomenon leads to an erroneous impression of the patient's true cardiac status and inadequate therapy. By means of echocardiography, hemodynamics can be assessed noninvasively both at rest and during exercise and this is particularly important since available medical therapy will prolong life preventing development of heart failure and reducing hospitalization in patients with asymptomatic left ventricular dysfunction. Echocardiography can be used as an important diagnostic tool in patients likely to have significant left ventricular dysfunction, i.e. long-standing systemic hypertension or status post-myocardial infarction. Since heart failure is both underdiagnosed and overdiagnosed, echocardiography can also be used to rule out heart failure in patients with other disease states simulating congestive symptomatology.
