Twelve executives with typical angina pectoris, given a 12-minute quiz, designed to be psychologically stressful, responded with ST depressions of greater than or equal to 1.0 mm. Each of these patients was given an exercise tolerance test on an upright bicycle to induce an amount of ST depression equivalent to that observed during the quiz. A statistical analysis was made of the products of th...

We examined the association between depression and anxiety and recurrent coronary heart disease events during the first 12 months subsequent to myocardial infarction. The Beck Depression Inventory and the State-Trait Anxiety Inventory were completed during hospitalization by 288 myocardial infarction patients. Peel Index score and Killip class were used as indices of disease severity. The 12-mo...

Using spontaneously beating rat myocardial cells as an in vitro model of myocardial depression, recent studies demonstrated that septic shock patients' sera frequently contain a myocardial depressant substance (MDS) that is associated with a reversible decrease in left ventricular ejection fraction (LVEF). To further characterize MDS, 50 consecutive patients with possible septic shock were stud...

Intracoronary administration of contrast materials causes myocardial depression which is related to serveral physiochemical properties of the contrast solution. The role of variations in ambient calcium ions (Ca++) in mediating this effect was evaluated in 19 anesthetized dogs. Sodium meglumine diatrizoate caused decreases in left ventricular peak systolic pressure (LVPSP),-12.6 +/- 3.2%, and d...

The effects of halothane (1.0-1.5%) on myocardial contractility, systemic vascular resistance (representing the majority of impedance to oscillatory flow), and left ventricular performance, and the interactions of these functions have been studied in openchested dogs, artificially ventilated and maintained in a state of basal narcosis with chloralose and urethane. Halothane reversibly depressed...

The circulatory responses to high equinalgesic doses of morphine are compared with those of pethidin. The decrease in mean arterial blood pressure in case of morphine was 28p.c., with a paralleled and identical de­crease in total peripheral resistance and no negative inotropic effects.  Pethidine decreased blood pressure 54p.c., as a result of peripheral vasodilation of 46p.c. and a sharp drop...

AIMS Depression in patients following myocardial infarction (MI) is associated with an increased risk of mortality, but this association may be confounded by cardiac disease severity. We explored the relationship between left ventricular ejection fraction (LVEF) and depression in MI patients. METHODS AND RESULTS In the Myocardial Infarction and Depression-Intervention Trial (MIND-IT), 1989 MI...
