Figure 1. Kaplan-Meier analysis of mortality rates in patients with myocardial viability.
Data are shown for patients with baseline end-systolic volume index (ESVI) above and below the median value of 84 ml/m2 according to treatment with coronary artery bypass surgery plus medical therapy (CABG) or medical therapy alone (MED). The relationship between viability, treatment assignment and survival is not influenced by ESVI (interaction P-value = 0.962).
