Abstract
The extracardiac effects of cardiac glycosides which are of greatest interest to us are those that involve an interaction of these drugs with neural tissue, and result in changes in cardiovascular function. In this category, we are especially interested in interactions of cardiac glycosides with two neural sites, namely, reflexogenic areas of the cardiovascular system, and the central nervous system (i. e., CNS sites that control sympathetic outflow). In this review we will discuss evidence documenting an interaction of cardiac glycosides with reflexogenic areas and with CNS sites that influence autonomic nervous system outflow. This will be followed by a discussion of evidence indicating that neuroexcitatory effects of cardiac glycosides play an important role in the cardiovascular effects of these agents. Interaction of cardiac glycosides with reflexogenic sites can explain many of the therapeutic effects of these drugs such as their antiarrhythmic effects and effects on preload, afterload, and renal function in patients with congestive heart failure. Interaction of cardiac glycosides with the CNS, specifically CNS sites that influence sympathetic outflow, can explain in part the ventricular tachyarrhythmias that occur with toxic doses of these agents.
