To examine whether digitalis use is associated with an increased mortality in certain highrisk subsets of patients with coronary artery disease, we analyzed the data of 14,547 patients in the Coronary Artery Surgery Study (CASS) registry who had significant coronary artery stenosis (¢ 70% narrowing) and received medical treatment for their disease. At the time of entry, 2600 patients (18%) Were...

The toxic effects of digitalis are attributable in part to poisoning of the enzyme Na+-K+ ATPase and in part to the interactions of digitalis with the sympathetic and parasympathetic nervous systems. Additional modifiers of the toxic effects of digitalis include the concentrations of ions such as K+ and Ca2+, the age of the subject and the extent and type of cardiac disease. At the cellular ele...
INTRODUCTION 1985 marks the bicentenary of the publication of William Withering's account of his studies on the clinical use of digitalis.' The first part of the present article reviews the use of digitalis before Withering and also the impact that his work had on the use of digitalis in the next hundred years or so. The final two sections deal with work in the present century concerning the cl...
W HILE animal studies have demonstrated that digitalis enhances the force of contraction of the nonfailing heart,'X the effects of this agent on ventricular contractility of the normal human heart are as yet unsettled. In the absence of clinical heart failure, digitalis administration is associated with either a slight decrease -9 or no significant change in cardiac output.10-'4 Such observatio...
PREVIOUS studies on the effect of digitalis on the hypothermic heart have indicated that the arrhythmic effects of hypothermia and digitalis are antagonistic. Those experiments were primarily intended to study the effect of digitalization on hypothermia using pharmacological doses of digitalis. In the experiments reported herein, the procedure was reversed in that it was thought to be of value ...
OBJECTIVE The course of anorexia nervosa often includes the emergence of bulimic symptoms and a crossover to the full syndrome of bulimia nervosa. However, clinicians' ability to predict who will develop bulimia nervosa is limited. The converse phenomenon, crossover from bulimia nervosa to anorexia nervosa, has not been investigated as thoroughly. The authors identified factors that are associa...
Preceding the study of the effect of digitalis upon coagulation of the blood, the reliability of the Lee and White method was determined in 173 normal adults. The effect of digitalis was then studied in cardiac patients before and after coinpenation and with normal controls in eaegroup: digitalis in clinical doses; addition of heparin to the blood; the heparin tolerance curve; the substitution ...
• The primary clinical indication for digitalis therapy is congestive heart failure and the inotropic effect of digitalis preparations has been demonstrated in both experimental animals and man. However, studies by Ross et al.' have shown that digitalis affects not only myocardial contractility but also total peripheral resistance. In view of the latter effects, we have to consider the possibil...
