View larger version (11K): [in a new window]   Figure 2 Kaplan-Meier cardiac event-free survival curves for the subset of patients with exercise echocardiographic abnormalities suggestive of single-vessel abnormalities. Event-free survival was greater in patients with abnormalities in the distribution of a vessel other than the left anterior descending coronary artery (LAD). LCX = left circumflex coronary artery; RCA = right coronary artery.
