View larger version (18K): [in a new window]   Figure 1 Kaplan-Meier curves depicting survival in patients having (overall anatomic myocardial perfusion index score [AMP] = 1) or not having (overall AMP = 0) unobstructed blood flow to a major vessel in at least one vascular territory. On the basis of univariate analysis, this factor was the strongest single factor which correlated with the risk of mortality after transmyocardial revascularization (TMR) (p = 0.002).

View larger version (17K): [in a new window]   Figure 2 Kaplan-Meier curves depicting survival in patients having (anterior AMP = 1) or not having (anterior AMP = 0) unobstructed blood flow to the left anterior descending artery. On the basis of univariate analysis, this factor also correlated with the risk of mortality after TMR (p = 0.005). Abbreviations as in Figure 1.

On the basis of univariate analysis, prior CABG predicted a better outcome after transmyocardial revascularization (TMR) (p = 0.003).

View larger version (18K): [in a new window]   Figure 4 Kaplan-Meier curves depicting survival in patients having (inferior AMP = 1) or not having (inferior AMP = 0) unobstructed blood flow to the posterior descending artery. On the basis of univariate analysis, this exhibited a statistically significant, though weak correlation with the risk of mortality after TMR (p = 0.05). Abbreviations as in Figure 1.
