Abstract
Congestive heart failure is a syndrome that is usually initiated by a reduction in pump function of the heart, i.e. a decrease in cardiac output. Initially, a reduction in cardiac output leads to unloading of baroreceptor reflex that, in turn, increases heart rate through vago-sympathetic mechanisms and total peripheral resistance via an increase in sympathetic outflow to vascular beds. In this review we are thinking on how baroreceptor reflex plays a role in the abnormal control of the circulation in heart failure. This review and our recent studies suggest that: (1) baroreceptor reflex is blunted in heart failure; (2) central angiotensin II and reactive oxygen species play an important role in blunted baroreceptor reflex; (3) cardiac sympathetic afferent stimulation and chemoreceptor reflex inhibit baroreceptor reflex; and (4) exercise training normalizes abnormal reflexes in the heart failure state.
