Treatment of Heart Failure With Fosinopril: An Angiotensin Converting Enzyme Inhibitor With a Dual and Compensatory Route of Excretion

Congestive heart failure (CHF) is one of the most common and clinically important cardiovascular diseases. This pathologic state is characterized not only by well-defined hemodynamic alterations, but also by complex abnormalities involving the sympathetic nervous system, the renin-angiotensin system, and other hormones involved in cardiovascular homeostasis. In addition, there is an abnormality in the homeostatic cardiovascular control exerted by arterial baroreceptors and the viscoelastic properties of medium-size arteries are altered, causing a reduction in arterial compliance. All of these abnormalities can be favorably affected by angiotensin converting enzyme (ACE) inhibitors, which have been shown to improve not only the hemodynamic and neurohumoral profiles of CHF, but also patient survival. CHF is accompanied with a decline or some sort of effect on renal function. An ACE inhibitor with a dual route of excretion, such as fosinopril, may be especially useful in treating patients with CHF.
