Figure 6 Probability of Cardiac Event–Free Survival in Patients With and Without a Stress-Induced Drop in LVEF

Probability of event–free survival as a function of mental stress-induced left ventricular ejection fraction (LVEF) change plotted at 2 prototypical values, 1 standard deviation (SD) below (LVEF change = –12.40%) and 1 SD above (LVEF change = +1.05%) the mean of the entire sample (LVEF change = –6.73%). Curves are adjusted for baseline LVEF, history of myocardial infarction, and age. The risk ratio associated with the lower curve compared with the higher curve is 2.40 (p = 0.02).
