Figure 4 Comparison of Rates for Late Revascularization

(Left) Kaplan-Meier curves for freedom from late myocardial revascularization among the coronary artery calcium (CAC) patients having nonischemic myocardial perfusion scintigraphy (MPS). (Right) Kaplan-Meier curves for freedom from late myocardial revascularization among the nonischemic MPS patients. CAD = coronary artery disease; LL = low likelihood.
