Abstract

The goals of heart failure therapy have shifted from purely hemodynamic manipulation to a combination of hemodynamic and neurohumoral modulation. Vasodilators with neurohumoral modulatory properties [such as ACE inhibitors (ACEi) and third generation β-blockers] have become the cornerstone of chronic heart failure therapy. These newer agents have proven to improve morbidity and mortality in adults with chronic heart failure. Pure vasodilators still have a place in the treatment of acute decompensated heart failure and in patients who are intolerant to ACEi or β-blocker therapy. In decompensated heart failure management, improvement of cardiac output is of paramount importance and restoration of normal hemodynamics takes priority over modulation of cardiac maladaptation. Under these circumstances agents that improve contractility and modify cardiac preload and afterload are used. In the intensive care unit setting inodilators offer the advantage of an added positive inotropic effect. NO donors play an important role when close titration of blood pressure is also needed. It is the purpose of this manuscript to address principles and current practice regarding the use of vasodilators in pediatric heart failure. ACE inhibitors and third generation β-blockers due to their importance in today’s therapeutic approach to heart failure are the focus of more detailed articles in this issue of Progress in Pediatric Cardiology.
